Hi everyone. I'm looking for some advices. One week ago, I received information about such a capability in solving my problems. Of course, I noted almost everything about eGPU at this forum, but not completely sure in feasibility of this configuration:
Toshiba satelite a300. intel core 2 duo T6400 2GHz, 4Gb RAM DDR2 800 Mhz, ATI mobility radeon hd3650
Thinking about to buy:
PE4L, GF Gigabyte 660ti or GF gtx MSI 670, Thermaltake TR2 630w
Here is question. What kind of problems can be there? Any advices about configuration?
I'm looking for a small PSU ( and cheap if possible :D ) for my GTX650. I intend to make a portable version for my eGPU, my current PSU is too big. Thanks alot? or any guide?
Is it possible to do X2 setup for my GTX 550 TI? cause the gpu doesn't use its full capabilities.
Instructions on that page highlight that recent Desktop drivers include the Optimus component. Meaning, no need to download the Verde driver and apply mods.

While TOLUD might leave a generous amount of pci-e space available, I found some HPs still allocate a system device right in the middle of a candidate contiguous pci-e block. There Setup 1.1x's pci-e compaction ma be able to help to allocate around the problem device.

If your system had a 4500MHD, HD, HD3000 or HD4000 iGPU then the NVidia driver would activate pci-e compression, netting 20-333% better performance. I'd suggest look at upgrading your system first to at least an inexpensive Sandy Bridge one (Lenovo E520, Dell Vostro 3350 or HP 4530s) which have the required iGPU and have a pci-e 2.0 expresscard slot. Just be sure to mate it to a pci-e 2.0 capable PE4L 2.1b.

I'd recommend upgrading to the a Lenovo E420 before you do that. It has a pci-e 2.0 expresscard slot so effectively provided the same bandwidth as x2 1.0 (x1 2.0).

I have another friend with a working GTX560ti I want to try just to see, and yet another friend with my exact laptop. (My friends all have cool stuff :D) So there is testing yet to be done. I think I'm just gonna dump the cash and build a tower even if this works though, and let my friend have the adapter...so much headache for so long, and I've got the cash for Black Friday. So...come on Newegg and Fry's, treat me good ;)

Indeed, only 10W are provided, but still, even the best MXM boards use up to 100W, just a fraction compared to similar desktop parts.

However, because there are many issues of MXM in mechanism and compatibility that will take us a lot of time to overcome.
So far we don’t have any plan for developing."
hi guys, i got a problem with my egpu (first time in over a year :/)
This morning while working my computer screen just went black and it looked like the gpu was gonna disengage (my laptopscreen brieflyflickered with the main screen image, but then it stayed black too). No big deal I thought. Now whenever I start and want to chainload the egpu to the OS I get a bluescreen (System Service exeption) after the gpu tries to engage. The laptop itself works fine without trying to use the egpu. Already did another 32bit compaction but i dont think thats the issue. :/
edit; I solved my problem by uninstalling the graphics driver, and installing the newest one from nvidia (306.97). Saying that, there is no hacked inf available for this one, but I read somewhere that Optimus is included now with the desktop drivers? Doesnt look to me like optimus is running and i dont have 3dmark on my computer right now to check if optimus is engaged.
Hey guys, I made an enclosure a la fatpolomanjr, and it works rather well.
Pros: Cheap (I made this out of the box my PSU came in), Easy to modify (but still strong enough to hold everything), and Easy to carry around.
Cons: Looks cheap (duh), probably will not last long (but I figure it ought to last as long as the video card is relevant).
Amusingly, my enclosure is actually more stable upside-down (thanks to wiring constraints and what-not).
I figure it's the perfect enclosure for the average guy in college. I haven't pushed my eGPU to its limits while in the enclosure, but the fans run ~ the same while in and out of the enclosure, so I don't think there ought to be any problems with it. I'll run them tonight, and update.
Also, I'm getting a used t9800 shipped to me, so we'll see how much of a bottleneck my cpu really is. I'll make a new post for that.
Anywho, Happy Thanksgiving everyone!
Edit: Ran 3DMark11 earlier today and got a 5497 graphics subscore, so it's pretty safe to assume the enclosure doesn't really hamper performance (previous score without enclosure was 5502).
<span "style=font-size:large">Updated: Implementation: i5-3320M 2.6 12.5" Dell E6230 + NVidia GTX660 @x1.2Opt + HD7870 @x1 2.0</span>
Conclusion for Sandy/Ivy Bridge systems with latest GTX6xx/HD7xxx card
<li>for expresscard/mPCIe systems capable of x1.2Opt: AMD has overall the better performance but the margin is minor.
<li>for Thunderbolt systems or systems incapable of x1.2Opt: AMD cards > NVidia cards.</ul>
Other factors favoring NVidia cards are CUDA and Optimus' internal LCD mode. Unfortunately AMD's equivalent Enduro is still being developed and doesn't appear to be easy to retrofit to eGPU solutions. Lucidlogix' Virtu has a 30-day trial version providing similar internal LCD rendering functionality to NVidia Optimus.
