Important Notices

13-4-2013: calling on notebook systemboard manufacturers (Foxconn, Inventec, etc) to attach their expresscards slot in the upcoming Intel Haswell platform using the pci-e 3.0 Northbridge rather than the pci-e 2.0 Southbridge. That will give eGPU users x1 3.0 link speed, equivalent to 2011-2013 Thunderbolt but better it as a x1 link allows NVidia Fermi/Keplar eGPU pci-e compression to engage as well. Use of the Expresscard slot means no annoying Intel Thunderbolt certification/licensing issues to deal with either.

12-8-2012: Notice about Thunderbolt (TB) eGPUs. Current TB gives a 10Gbps channel to the eGPU, equivalent to x2 2.0+12.5% bandwidth as discussed, less than the x4 2.0 original thought. It's only slightly doubles what Sandy/Ivy Bridge expresscard/mPCIe x1 2.0 notebooks provide at considerably more cost. For x4 2.0 performance need to wait till 2014 when 20Gbps Thunderbolt will be available.

A US$140 BPlus TH05 x2 2.0 Thunderbolt adapter is excellent value to accompany a 2011/2012 Macbook. I'd avoid overpriced Sonnet/Magma TB boxes for their measly 12.5% better performance over a TH05. A TH05 delivers 89% of their performance for less than 1/3 their price. An absolute bargain!! <--- TH05 is discontinued. See TH05 Recall Notice for details.

If you run Windows 7 exclusively, it is very easy to enable the eGPU without a reboot. Just standby the system, plug in the PE4L, resume, Windows 7 detects the desktop GPU and reverts back to how you have your desktop setup (eg: HD5750 as primary or extended display). Easy.

The performance difference b/w the onboard 4500MHD/HD3000 and an attached desktop eGPU is staggering. The Inspiron 1440 using the x1E tweak saw 3dmark06 go from 866 to 9551. RE5 benchmark went from an unplayable 4.1FPS to a very playabe 60.9FPS. The HP 2560P's x1.2Opt link saw 3dmark06 increase over 4 times to 18340 and RE5 gave an average of 148.3FPS(!!), even allowing the internal LCD to be driven by the eGPU.

PRE PURCHASE FAQ >>>

1. How does a DIY eGPU differ from a Villagetronic ViDock3/4?

Spoiler

2. How can I check if my notebook is compatible with an eGPU?

Spoiler

If the system has a dGPU then ensure it's switchable with the Intel 4500MHD/HD/HD3000/HD4000 providing primary video if you want to do a higher performance Optimus x1.Opt setup with allows accelerated graphics to the internal LCD as well as an external LCD.

Pretty much any notebook can be eGPU compatible if it's run with 2GB of RAM. 95% are OK with 3GB of RAM. It's only if it runs 4GB or more that there needs to be particular attention paid to free pci-e configuration space to host it, which can be checked by:

(Update 3-14-2012) A DSDT override extending the root bridge into 36-bit can allow ALL systems with a 64-bit CPU and chipset (anything after 2007) to be eGPU compatible when used with Windows 7 and the latest iGPU/dGPU/eGPU drivers with up to 48GB of RAM installed. So the DSDT override solution eliminates the restrictions listed below.

if the system has a switchable iGPU+ATIAMD dGPU or switchable iGPU+NVidia Optimus dGPU configuration then can use Setup 1.x to disable the dGPU component to allow a eGPU to use it's pci-e space. This also works with all Intel chipset systems with NVidia or ATiAMD switchable graphics with the exception that Series-6 AMD switchable graphics hasn't been confirmed to be allow such disabling as explained.
if the system has only a dGPU or iGPU (not switchable) then check the system's TOLUD+Large Memory to ensure there will be no issues running 4GB+. Check in Device Manager. Set View to "Resources by connection" & expand the Memory tree like shown.

If you have the somewhat rare large memory memory entry then the eGPU can be hosted in 36-bit pci-e space.

If not, as is far more common, then the eGPU will be hosted in 32-bit pci-e space where you'll require TOLUD being 3.25GB or less. Identify this by looking for the first PCI bus entry with a 8 digit memory address. Compare it with table below (thanks Kizwan!):

First PCI bus with 8 digits memory address TOLUD
E0000000 3.5GB
D0000000 3.25GB
C0000000 3GB
B0000000 2.75GB
A0000000 2.50GB

As long as TOLUD is equal or lower than 0xD0000000 (3.25GB) your notebook will have enough 32-bit PCI space for a eGPU to work with 4GB or more of system RAM. See details. Some examples:
- older C2D/Arrandale Dell Latitudes could only do a 3GB setup. A fix requested in REQ: bios mods to make Vostro/Latitude eGPU friendly.
- Sandy Bridge Lenovo X & T series require the latest bios to do a 4GB+ setup. See Petition to fix TOLUD in newer BIOS files - Lenovo Community.
There is some exception to this rule. We've found some systems have bios allocate systemboard devices that sit right in the middle of a "free" 32-bit 256MB pci-e block that cannot be relocated and prevents an eGPU from that space.

To be absolutely sure an eGPU can be accomodated requires booting Setup 1.x and performing an 32-bit PCI "All" compaction, and seeing if you now have 256MB free shown in the Status window and confirming your system can chainload to Windows. If not, but you do have 128MB contiguous free space shown then consider that NVidia Fermi/Keplar cards use a fragmented 128MB+32MB+16MB PCI BAR so might still be able to be allocated where AMD cards require a straight 256MB contiguous block cannot.

If this is a bit too confusing then proceed to boot Setup 1.x, run Save Diags->compact_fails, then Save Diags->Windows_fails following the prompts. Boot back to Windows, mount the Setup 1.x image, archive the v:\diag folder with Winrar/WinZIP, upload to mediafire.com and link here for analysis of your diagnostic output.

FIRST STEPS >>>

See Techradar's How to make an external laptop graphics adaptor article for an overview.

1. What parts do I need and where can I buy them?

Spoiler

Above: Fujitsu S710 eGPU implementation - US$85 PE4H-EC2C(comes with SWEX and PCIEMM-030) plus a HD5770+ATX PSU

1. The expresscard or mPCIe to PCIe adapter. See related 2. Can my system use PE4H's x2 1.0.. in FAQ. You'll need the US$92-shipped PE4L 2.1 if want the faster pci-e 2.0 performance on a Sandy/Ivy Bridge Series-6/7 notebooks. The linked units below are pci-e 1.1 which is the maximum speed available on Series-5 (1st gen i-cores) or older chipsets.

x1 or x2 link mode¹		x2 link mode
US$71/$76 PE4L-EC2C or PE4L-PM3N / & US$22/$7 shipping	US$91 PE4H-EC2C or PE4H-PM3N / & US$22/$7 shipping	US$91 PE4H-EC2C or PE4H-PM3N / & US$20 PM3N US$10 PCIEMM-100 US$28/$7 shipping
US$93/$83 (BPlus/HIT)	US$113/$98 (BPlus/HIT)	US$149/$131 (BPlus/HIT)

HIT: Harmonic Inversion Technology. A US distributor of BPlus' PE4H-EC2C/PE4L-EC2C with a cheaper base price, cheaper US$7 UPS shipping, plus are entitled to the Setup 1.x software (valued at US$25) upon your request as part of your purchase. It is recommended US customers purchase from HIT as highlighted.
¹ buying the PE4H means can acquire parts later to do a x2 link
Recommend: an extra US$6-shipped DX mini hdmi cable. 2 users requiring a replacement part for the setup to work.

Which one? PE4L or PE4H?

PE4H 2.4 has a sturdier base, can allow a 15-19V DC jack input and up to x4 1.0 connectivity [note: pci-e 1.x only].
PE4L 1.5 is not as sturdy but is smaller and lighter. It can allow a 12V DC jack input and x1-only connectivty. [note: pci-e 1.x only]
PE4L 2.1b is pci-e 2.x compliant and recommended for Sandy/Ivy bridge expresscard/mPCIe equipped systems.

Amfeltec has a cheaper x1 1.0 mPCIe kit starting at US$29 here.

2. A video card of your choice

Review next item 2. Which video card do you recommend for best performance on my system? to determine if an AMD or NVIDIA solution will perform better on your setup.

3. A suitable power supply to drive your video card

Can determine how much power you require by counting the number of 6 or 8-pin PCIe connectors on your video card. The total power required to drive it will then be:

75W for the slot¹
+ 75W for each 6-pin PCIe connector
+ 150W for each 8-pin PCIe connector

¹: Can be supplied using either the DC or the floppy molex jack. The DC jack differs on the PE4L and PE4H: PE4L takes 12V input, PE4H takes 15-20V (regulated) > 84W. The AC adapter must have a 2.5mm/5.5mm or 2.5mm/5mm barrel end to use the DC jack. The floppy molex input is used with an ATX PSU..

Power can be supplied by using either an ATX PSU or AC adapters. Can also split AC adapter power to supply a PCIe connector as shown here.

Refer also to ithildin's and serialk11r's PSU recomendations for details on how to read the PSU labelling. 430W may actually mean it only supplies 168W for our purposes!!

2. Which video card do you recommend for best performance on my system?

This will be determined by your chipset, if additional ports available for x2 linkage and whether you have Intel 4500MHD, HD, HD3000 or HD4000 graphics. The matrix below makes recommendations based on the system chipset with:

-LIME recommend NVIDIA Fermi/Keplar (GT430 or better) solution for best performance

-RED recommend AMD HD5750 or better solution for best performance

-CYAN choose based on preferred performance bias: DX9 (AMD HD5750 or better) or DX10/DX11 (NVIDIA Fermi/Keplar). Though specifically for x1 1.0 I recommend a system upgrade to a better performing candidate as users find uneven & choppy performance. Thunderbolt users may still elect NVidia Optimus solution (if have an iGPU) as then can then render the image to the internal LCD. Refer to Performance: AMD versus NVIDIA benchmark results to help you decide. If not sure then suggest a NVIDIA Fermi/Keplar solution which on balance gives better overall performance and has the option of x1.Opt with the right notebook. Note: if the NVIDIA x1.Opt driver was unlocked to allow primary video cards other than Intel 4500MHD/HD/HD3000/HD4000 plus it engaged with x2 links then I would recommend only NVIDIA solutions.

Left-to-right: slowest-to-fastest ~~with NVIDIA x1.Opt and x2 delivering similiar performance~~

¹ provides full duplex performance equivalent to x1E on Intel chipsets.

² Optimus tweak engages only when Intel 4500MHD/HD/HD3000/HD4000 primary graphics AND x1 link is detected, improving mostly DX9 performance by 20-333% with some DX10 improvements as well. Provides ability for the internal LCD to render games running on the external GPU.

³ x1E tweak uses a x2 link on port1, 3 or 5 with a single lane for 15-30% more perf (AMD/non-Fermi|Keplar NVIDIA only).
⁴ x2E tweak use two lanes of a x4 link, [port1+2] as EC+mPCIe or mPCIe+mPCIe for 30-60% more perf (AMD/non-Fermi|Keplar NVIDIA only).
⁵ x2=combining expresscard+mPCIe or mPCIe+mPCIe slots [p1+2], [p3+4], [p5+6] or [p7+8]; x4=[p1+2+3+4] or [p5+6+7+8].
⁶Series-6/7: Only for Thunderbolt-equipped notebooks. Trying to combine mPCIe+expresscard slots no longer possible as Intel now locking the link width in the flash descriptor. Requires advanced bios hacking to configure x2 link, cannot be done using Setup 1.x.
⁷: would only be possible if the expresscard slot was wired to the northbridge which runs pci-e 3.0. All expresscard slots so far have been using the southbridge which is currently limited to pci-e 2.0. So we can say this is not possible.
? Don't know if non-Intel chipsets can do x2 links.

If going AMD, recommend a HD5xxx+ series card over a HD4xxx series due to their more efficient usage of PCIe bandwidth. Benchmarks would predict a HD5670 to outperform a HD4870.

Avoid twin-gpu cards like a HD6970/GTX590 since they require 2x256MB PCIe space windows which might be difficult to accomodate.

Examples based on power consumption requirements

12V/75W adapter: HD5670, unplugged HD5750, NVIDIA GT430.
12v/80w: specific HD5750 units. See comment here, implemented here.
12V/120W: GTS450 described here using DC adapter that is shared between notebook and eGPU

3. Is it possible to get an enclosure?

A good thread to see some professional designed enclosures is at redback79's DIY enclosure project. In addition, BPlus offer DIY Box enclosure for US$60 that uncannily resembles a US$10 acrylic aquarium with plastic posts and some hole cutouts. There are others for sale or examples to build on your own, for example:

BPlus' DIY Box, surrealix's laser-cut acrylic, fatpolomanjr's cardboard box, (celli's IKEA drawer, Elmopol's XB360, Joss27's 5.25" SCSI box, Wolf Tohsaka's Livebox Mini, timohour's floppy holder, fr0z3n's carry-it, Fujian stand/enclosure, airzone (1U), Kallogan (192W AC), hlgr, aodioxp, SimoxTav, #1, sprtnbsblplya, Agent9, Lurifax (mini ITX), kizwan (Aero QX2000, mITX), the endless +XB360 PSU, max_headroom and Oddious (1U), lightnica (JuiceBox), pengy_666's 5.25" drive enclosure, 12V/120W "portable", pimped-up (xb360) which is similar to Building an eGPU (CUDA).

Key
RED - a x2 1.0 link using a PE4H linking expresscard+mPCIe or mPCIe+mPCIe. All others are x1 1.0.
ORANGE - appears to have port layout to do a high-performance x2 1.0 setup using either [port1+2], [port3+4], [port5+6], [port7+8]
GREEN - video card that requires only a compact 12v/80w AC adapter for power. No external ATX PSU needed.

All tested at 1280x800 except 3dmark06 which used the default 1280x1024 and those marked *

x1.1: x1 2.0 (5GT/s) capable system running at x1 1.0 (2.5GT/s) if pci-e 2.0 DIY eGPU hardware is used.
x1.Opt: system with Intel 4500MHD, HD, HD3000 or HD4000 iGPU primary graphics using NVIDIA Optimus for higher performance + internal LCD mode.
x2~~.Opt~~ = x2 link, Intel HD graphics, Optimus driver, but Optimus performance tweak only engages on x1 link as found.
x1E/x2E: apply x1E tweak to ATI cards and older NVIDIA cards on series-4 or older Intel chipsets to get ~full duplex performance
x2.2T: negotiates at x4 2.0 with GPU but is handicapped by 10Gbps Thunderbolt link (~x2 2.0 + 12.5%)

¹ Requires DIY eGPU Setup 1.x to overcome 12: cannot allocate resources and/or to set specific port requirements.

² EC/mPCIe: expresscard/mini_pci-e slot used by a EC2C/PM3N product. Port layout required for x1E/x2/x2E/x4 mode. Intel chipsets' require port1 enabled for other ports to work so port1 may not be a physical mPCIe/EC slot.

Systems incapable of running 4GB+ setups for reasons as explained. These will require a DSDT override to work.

⁴1st-gen i-core and core2Duo Dell Latitude have TOLUD=3.5GB.
MSI CRx20
Lenovo T420 doesn't work unless use bios 1.15 as explained.
Sony E-Series i-core has an unusual reserved system device. Only a NVIDIA card can fit around it in 32-bit space.
Dell XPS 1530M has TOLUD=3.5GB as explained.

Systems capable of a higher performance x4 or x2 PCIe links

The Orange and Red systems shown in the above table. Also:

x4 1.0 (four x1 ports): Dell Inspiron 1520, Vostro 1500, XPS 1640/1645, Lenovo X200.
x1 2.0 (single port): ExpressCard 2.0 with Series-6 chipsets. Not Series-5 PCIe 2.0 chipsets
x2 1.0 (two x1 ports): Acer 5920G, 6920G, 6930G, 8930G. BenQ S41. Dell M1530, E4300, E6400?, Studio 1558 (WWAN=port1, wifi=port2), D630, D830, E6410, E5500, Vostro 1310, Fujitsu Amilo xi2555, HP DV9690en, HDX9000, Lenovo T400s?, T510, Y450/Y550, W510, MSI GT627 &, Toshiba A665-3D.

Systems not capable of a higher performance x2 1.0 PCIe link shown in black in the table above, as well as:

Acer 4741G(mPCIe), 5820TG(mPCIe), 8935G, Asus F3JC, G60, N61JQ, Dell Vostro_3400, Inspiron_1545*, HP DV3-2232tx, DV6-2119TX, DV7-3110TX, Lenovo G560, x201s, MSI A620x/Cx620, U200 (mPCIe), Samsung R580, Sony VGNNW29GF, Toshiba A300*, A500-026, A500-031, M305, P500-01g, R700, U500-00k.

* = can do a x1E tweak, relevant to only ATI cards and older NVIDIA cards, since the ExpressCard slot is an odd numbered port with nothing occupying the next port and is a series-4 or older Intel chipset.

Thank you for the encouragement. I had to resort to getting messages through via proxy (Khenglish) to help out. Any talk about me, or the ban or redirecting users to TI will see the post deleted and the user possibly banned. It's a crazy level of censorship. Doesn't look like the instigating mods are prepard to admit any wrongdoing or back down either. Sigh.

Please PM users on NBR directing them here if need my assistance

So may need some proxy services by NBR members aware of what's happened to help other unaware users along. They could PM users to come and post here if they require my assistance.

I'll still be maintaining the DIY eGPU experiences page, updating content and adding new entries. Good thing is I have mod access in the DIY eGPU area here giving a lot of freedom to reorganize stuff. So for instance, Setup 1.1x and DIY eGPU Troubeshooting will soon have their own stickied threads

There's plenty of other content (eg: modded drivers, SB/Ivy Bridge eGPU notebooks) for other users who want to volunteer to maintain it too.

A place to discuss your opinion on my NBR ban

It's being discussed on reddit at http://www.reddit.com/r/gaming/comme...hans_g/c6bsxyu which shows concern over the moderator abuses of positional power in my ban. You are welcome to join in to voice your opinions about it.

no prob!

the last patch you provided khenglish worked great. i got the egpu up and running, but i used ccleaner (oops?), earlier, and now the laptop can't detect the egpu! i tried to reinstall setup 1.x, but i still can't get it to detect the egpu. any thoughts?

03-27-2013: Masaharu's reply requesting MXM3 product

Dear Mr. Nando,

Thank you for your information.

Roger,

Please refer MXM3 information for new product.

Best Regards,

Hi Masaharu,

Please monitor the development of this: EXP GDC 笔记本Expresscard to MXM3外置独立显卡标准套装

We've recently had a result of a user attaching to the BPlus eGPU gear to a htpc pci-e 3.0 port getting x1 3.0 results:

Egpu for a desktop (htpc)

Now notebooks have expresscard slots off the Southbridge which is limited to pci-e 2.0. The Northbridge on a Series-7 notebook is pci-e 3.0, however, no manufacturer is attaching the expresscard slot off that port. Meaning, you could route the MXM slot out as an expresscard 3.0 slot using an adapter to a PE4L 2.1b and get x1 3.0 (inc Optimus) performance using an eGPU. Then again, you could route it as a full external x16 3.0 slot too

Something to keep an eye on.

Basically, L060A can not support pci-e 2.0.

On some desktop system, L060A can work as pcie-e 2.0, however the behavior is not stable.

Besides, L060A can not work as pci-e2.0 on some laptop PCs on which PM060A or EC060A can works as pci-e2.0.

So, for pci-e 2.0 tests, we recommend not to use L060A, but to use PE4L-EC060A 2.1b and PE4L-PM060A 2.1b. [/QUOTE]

Yes, it was successfully connected with PCIe 2.0. Basically, before we develop EC060A, we made L060A type sample and direct cable soldering to PCB worked fine.

We are very sorry but we are not able to imagine the product well. Also, we think to switch PCIe devices might be more difficult.

To get the Thunderbolt products are headaches for us too.

Unfortunately, Thunderbolt group does not offer group discount or such kind of thing to us.

Now, it is the best way to use my nephew's name to get academic discount from apple. I heard there is Thunderbolt plugfest in Sep or Oct, and we will meet a lot of Thunderbolt vendors. So, we will ask them if they have discount.

Unfortunately, PCIe 2.0 is not successful in our lab, probably because
using PCIe-mPCIe adapter on desktop PC.
So, when KZ-B26 is directly attached to laptop mPCIe slot, it may
be still chance to work properly.

> KZ-B26 questions
> 1. Is it pci-e 2.0 compliant end-to-end?

So far, it is not successful.
However, similar product KZ-B21 using equivalent cable works
fine with PCIe 2.0, so we suppose KZ-B26 should work fine with PCIe2.0.
KZ-B21 (Flexible x1 PCI Express Extender)
Also, shorter cables (10cm or 20cm) have much more chance
for PCIe2.0 than present (30cm/12inch) cable.

We suppose KZ-B26 can work the kind of use.

It's interesting idea!
We will think about it in the next version.

We can understand the situation, PCIe2.0 x2 is not large leap

Unfortunately, x4 can not be supported by TH05, because we
use IC with Thunderbolt x1 channel and PCIe 2.0 x2.
In 2012, and early 2013, we will keep using the IC, though
there are TBTx2+PCIe2.0x2 ICs.

First we will develop all product with TBT IC with TBTx1+PCIe2.0x2.
After we get experience of TBT, we will use TBTx2+PCIe2.0x4 for
higher performance.
Step by step and tick-tock.

We suppose PCIe2.0x4 (5Gbps x4) is reasonable, because
TBT I/F is 10Gbps x2.
So, TBT I/F itself will be bottle neck for PCIe3.0x4.
PCIe3.0x2 may possible, however, we do not see PCIe3.0 on
intel road-map so far.

So far, we do not have plan to add DisplayPort to our products,
because TBT IC we use does not have the option.
After we use another IC with PCIe2.0 x4, we will add DP port.

Yes, intel's NDA is very strict.
We suppose intel wants to control TBT market strictly
because it's very high speed and the market should not
be messy with low quality products.
So only intel certified products can be released, and
hopefully TH05 should be certified in the end of August.
After that we can release samples for limited quantity.

Yes, 24pin female connector is on PE4H v3.0.

Power supply from PCIe slot is 75W. 300W is available 6pin and 8pin PCIe power connectors are connected from ATX power to VGA board.

> The other benefits of the ATX connector on the PE4H 3.0 would be:

PE4H v3.0 power is controlled by the hardware power switch and ExpressCard 3.3V power. Power from ATX power and 19V AC adapter are controlled by ExpressCard 3.3V power, external PS_ON is not necessary.

Unfortunately, PE4H v3.0 is not so intelligent. PE4H v3.0 just check 3.3V from Expresscard, it means, ExpressCard slot portion of PE4H v3.0 is inserted to ExpressCard slot or not. If ExpressCard 3.3V is provided, main power will be on.

Regarding PE4L v2.1, 12V/5V could be maximum. We checked PE4L layout. For DC jack connector to floppy power cable, 12V/3A (5A at most) should be capable. So, additional jumper is required as you suggested.

Even though we tried to have additional power plane for 12V, we were not able to find it on present PCB surface budget. So, we also suggest to add external jumper to enhance 12V and GND between DC jack connector and floppy power connector to use 150W AC adapter for PCIe 6/8pin power

01-21-2012: PE4L 2.1 (pci-e 2.0) will be available on Feb-20-2012 as a US$70+shipping engineering sample. Detailed photos of one are here.

1-19-2012: Masaharu from BPlus response on cable length and some other requests

Spoiler

>Upon asking the DIY eGPU community for cable length we get all sorts of replies b/w 45cm to 200cm.

At present we consider 60cm for product release which is same length as cable length with v1.5 package. At this time at least 100cm must be achieved for the 60cm product release. For internal testing, the target is 200cm, we may have 100cm if the 200cm is ok.

> 1. You can see that the original idea of a socketed cable was a good one. Perhaps continue to test different sockets

Regarding this kind of configuration, we already tested and failed many times. So, we came to conclusion that mHDMI cable must be soldered at the both ends of the cable.

> 2. Can add a new PS_ON output connector on the PE4L/PE4L? This was requested some time ago.

As v2.1 was derived from v1.5 so the PS_ON is not applied for v2.1. We will have the PS_ON and other small fixes on next version, because it can not be on time for v2.1 release.

> 3. Ensure you have 12V->3.3V voltage regulation @ 3A (10W) so the user doesn't need an auxilery 5V/3.3V input.
> That is the pci-e spec for maximum 3.3V input power.

12v-3.3v regulator can not be applied for PE4L because the regulator exceeds thermal envelope of PE4L. Instead, we will apply another way that put 5V from USB port for 5v-3.3v regulator to achieve 3A/10W for 3.3v power plane;

3.3V from ExpressCard: 1.3A
5V-3.3V on PE4L: 2A
Total 3.3V current: 3.3A

This time, we have different type of PCIe x16 slot connector so that your current issue will not occur. Please refer picture below. There is 4mm space on the rear side of PCIe boards so the most of VGA can be used.

· bplus are now developing an active transmitter/receiver pair for reliable pci-e 2.0 transmission over copper. Their previous attempt at a new flat cable only allowed pci-e 1.0 over a longer length as shown. It uses a mini HDMI connector.

no more 4GB+ issues: use a DSDT override to extend the root bridge into 36-bit space (Windows 7 only - MacOS/Linux are unaffected)

36-bit DSDT override user contribution repository>>>

Below are the contributed DSDT overrides created using the details of this post. Linked here to easily find them.

Dell: Latitude E4300, E4310 (nando4), E6400 (dummyaccount), Studio 1557 (kizwan)
Samsung: 400B2B (xxlukexx)

Introduction>>>

This problem and solution is only relevant to Windows operating systems. MacOS ignores the root bridge and can allocate in 64-bit space as kizwan found here. Linux has a "noCRS" kernel parameter to ignore the root bridge boundaries so the OS can also also allocate in full 64-bit pci-e space.

A small number of problematic systems like the Dell Latitude Ex410 series, Samsung Series-4, Sony F-Series and MSI CRx20 have insufficient free 32-bit PCI space to accomodate a eGPU if have 4GB or more of RAM installed. They can't use Setup 1.x's PCI compaction to create sufficient space because they either have TOLUD=3.5GB, or a lower TOLUD like 3.25GB but with an unmovable systemboard device occupying candidate free pci space making it unusable.

Perform a DSDT override or a in-memory DSDT substitution?

NOTE: Win8 doesn't allow a registry DSDT override as described below. So either stick with Win7 or do a Win8: Perform a DSDT substitution within Setup 1.1x to overcome TOLUD issues. Win7 users who don't want to do the registry override can also perform a DSDT substitution.

Need a 36-bit root bridge DSDT override

I happened to run into one of these problematic systems - a Dell E4310 with TOLUD=3.5G, which can be maxxed out at 16GB of RAM. It's too nice an ultraportable to be need to resort to 3GB of RAM to use an eGPU. So I set of in pursuit of how to add a DIY eGPU to it which is documented below. The same solution can be applied to any 3-gens old PM965 chipsets (2007) or newer system. They have a 64-bit CPU and chipset so are fully PAE/64-bit compatible. This fix could also be applied for systems that would otherwise require Setup 1.x's PCI compaction to free up 32-bit PCI space, making it a nice way of fixing a number of problems.

The solution requires the eGPU to be hosted in 36-bit PCI space. However, just using Setup 1.x's 36-bit PCI compaction on the eGPU to relocate it in such space will see the eGPU still give an error 12 in Device Manager. Why is that?

Avlan confirmed that the 32-bit root bridge definition limited allocation only to 32-bit space. The fix being a modified DSDT loaded as a registry override that extends the root bridge (ACPI PNP0A08 or PNP0A03 device) into 36-bit space. Avlan's fix was cryptic so wasn't attempted on other systems.

After a bit of digging I found the QWORDMemory DSDT static resource entry can be used to easily extend root bridge entry into 36-bit space.

Ref: [Qemu-devel] [PATCH 6/6] 64bit PCI range in _CRS table plus two examples at virtualbox and Coreboot.

Example 36-bit root bridge DSDT override>>>

We can do extend the E4310's root bridge into 36-bit space with the following steps. The iasl and asl tools used plus the modified E4310 DSDT table are in DELL-36b-root-bridge.rar.

NOTE: kizwan expands steps 1-3 here. Useful if you need more assistance with these steps. Kizwan also provides a video tutorial here.

1. Identify the resources used by the PNP0A08 or PNP0A03 devices in Windows. This can be found by perusing Device Manager->Resources by connection->Memory. Then check the last PCI BUS entry. Eg:

Spoiler

2. Capture the DSDT table using:

Code:

iasl -g

3. Open the resultant [].dsl file and look for the PNP0A08/PNP0A03 'DWordMemory' resource entries. Under the last DWordMemory entry in that area, add a 'QWordMemory' (64-bit) entry such as the one in RED below. I ensure that I stay in the 36-bit range (< 64GB) so the location is compatible with the PAE-capable Win7 32-bit. I also chose a location above 48GB so we won't have issues with maxxed out memory. The range chosen was 48.5GB to 56.25GB.

Code:

DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
   0x00000000,         // Granularity
   0x000A0000,         // Range Minimum
   0x000BFFFF,         // Range Maximum
   0x00000000,         // Translation Offset
   0x00020000,         // Length
   ,, , AddressRangeMemory, TypeStatic)

QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
   0x0000000000000000, // Granularity
   0x0000000C20000000, // Range Minimum,  set it to 48.5GB
   0x0000000E0FFFFFFF, // Range Maximum,  set it to 56.25GB
   0x0000000000000000, // Translation Offset
   0x00000001F0000000, // Length calculated by Range Max - Range Min.
   ,, , AddressRangeMemory, TypeStatic)

4. Create a [].aml file with the 'iasl [].dsl' compiler directive. It may fail to compile because of of some minor syntax errors in the dsl file. Those will need to be corrected with common fixes explained in How to fixed DSDT errors? (kizwan). It may help to try a newer IASL version 5.0 iasl-win-20120320.zip and ask for guidance at tonymacx86.com DSDT forums. DSDT editting alone could have it's own forum. Then try compiling your DSDT again.

Code:

iasl E4310.dsl

5. Loading the [].aml file into into the registry as a DSDT override using 'asl /loadtable [].aml'. You must be an admin user for this to be successful.

Code:

asl /loadtable E4310.aml

6. Check you now have a 36-bit PCI BUS (> 0x100000000) entry in Device Manager->Resources by Connection->Memory as shown below:

Spoiler

7. While my PE4L 2.1 isn't working atm, so I can't confirm it on the E4310, I can say the same fix was done on a Dell E4300 and Win7 did automatically allocate the eGPU into the 36-bit space. If you still see error 12 then there are two options to pursue:

i) Re plug'n'play the devices. Go into Device Manager -> Video cards, delete the eGPU. Also go into Device Manager -> System devices and delete the PCI Express Root Port x entries.

Upon restarting the system, halt Win7 startup with F8, attach and power on your eGPU and then proceed to load Win7. Win7 should now be clever enough to re-allocate the eGPU into 36-bit space upon realizing there is insufficient 32-bit space to host it.

Can go one step further and delete your eGPU NVidia/ATiAMD driver, restart the system and reload it. That may help as well.

(ii) Hard allocate the eGPU into 36-bit PCI space before booting Win7 using Setup 1.x. The next Setup 1.11a has integrated the DSDT override details so will give the user a list of endpoints that bound the PCI compaction, eg: '36-bit (56.25GB)'.

With the current Setup 1.10b5 need to do this manually. At the DOS prompt create a new pci.bat relocating the eGPU to 56.00GB:

Code:

cd %DRV%:\config
compact pciend E10000000 useonly [eGPU PCI ID] makebatch pci.bat import devcon.txt
call pci
:: Chainload the MBR
call grub4dos mbr

The result will be similar to that shown in the spoiler in step 6 above, but with the eGPU rather then the Intel HD iGPU being in 36-bit PCI space. Can then proceed to automate this by editting your %DRV%:\config\startup.bat (or V:\config\startup.bat in windows) so can just select the Automated startup via startup.bat Setup 1.x bootitem and have it do everything for you:

Code:

call speedup lbacache
call vidwait 60 [eGPU PCIID]
call vidinit -d [eGPU PCIID]
call pci
call grub4dos mbr

Testing results>>>

* Dell E4310 (nando4): SUCCESS! I relocated the Intel HD iGPU into 36-bit space using Setup 1.x as shown in step 6 above freeing 256MB of contiguous 32-bit space to host an eGPU, so it will definitely work. Plus there is plenty of 36-bit space for the eGPU too. Unfortunately my PE4L 2.1 isn't working so I can't show the iGPU+eGPU both being active but it will work

* Dell Studio 1557 (Kizwan): SUCCESS! His HD5870 successfully relocated to 36-bit pci-e space.

FAQ>>>

1. When do I need to hotplug my eGPU to overcome the error12 with a DSDT override?(kizwan)

2. How to clean the DSDT override properly? (kizwan)

(*We will need to delete DSDT key in registry)

Code:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSetXXX\services\ACPI\Parameters\DSDT

* where XXX are 001, 002, 003 & so on.

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ACPI\Parameters\DSDT

I didn't really tested whether deleting "DSDT" key in ControlSetXXX (XXX are 001, 002, 003 & so on) really necessary but I will test this when I test your latest Setup 1.x. For sure deleting "DSDT" key in CurrentControlSet is necessary. You can access registry via command line. So, you can put it in .bat file.

Those fixes are rolled into the development version of Setup 1.11a with a stack of others. It's release is pending more fixes/updates to compact whose author will be working with an iGPU+dGPU+eGPU rig soon so will be seeing long outstanding bugs and features requested firsthand. Trying also to organize a way to get a 2011+ Macbook too so could tweak the software to work on it too. Looks like Thunderbolt systems still encounter error 12.

Can you remind me of the system in question here? Are you using expresscard/mPCIe, PE4H/PE4L version? The method I've found was always successful in detecting the eGPU being:

1. Disconnect and power off the eGPU from the notebook.
2. Boot Setup 1.1x
3. Power on the eGPU.
4. Hotplug the EC2C (expresscard) or PM3N (mPCIe). A variation of this if using PE4H 2.4 or PE4L 1.5 is to leave the EC2C in the expresscard slot throughout steps 1-3 above but just attach the mHDMI cable to it with the powered eGPU to get it detected.

Some systems do not boot with the eGPU powered and attached. That's a great troubleshooting step to confirm the hardware itself works as the bios sees it and doesn't like it. I believe the Troubleshooting FAQ will be up in the next day or two. It has pretty much the same steps as I list above for getting an eGPU detected.

This is actually another system. My dgpu in my last system totally crashed and i was no longer able to see any video output...

this system is a fujitsu lifebook n3430 that i got from a friend.
Win XP Media Center Edition SP3
Intel T2300 @ 1.66 GHz
512 RAM (i know it sucks - is it even enough RAM)
integrated intel video

egpu is GTX 460SE, connected through PE4L-EC2C with Corsair CX430 psu

Actually, i have tried all of the methods you have listed (in setup 1.x help menus) including the one above. nothing has worked. before it actually worked when the egpu was plugged in before i turned on the laptop, but i'm not sure what happened. do i need to get more memory? the laptop can support up to 2gb.

First PCI bus with 8 digits memory address	TOLUD
E0000000	3.5GB
D0000000	3.25GB
C0000000	3GB
B0000000	2.75GB
A0000000	2.50GB
