taiwan Posted November 26, 2014 Share Posted November 26, 2014 Hi guys, stumbled across here on google. i recently bought this laptop from pcspecialist. i opted for the 880m with a 4810mq. 16gb ram, ssd and hdd the cpu doesnt seem to be an issue, it peaks at about 75-80°c depending on room temp. but the fan isnt on max setting. (stock controlled) the gpu however seems to really crank up and slowely throttles itself from the 849mhz(??) starting @ 36°c odd, and comes down to roughly 810mhz and holding then around 90-93°c although i do see times of 405mhz for split seconds randomly. the fan is at max speed even when the its stock controlled. this is with a lap cooler to aid cooling it used to be hotter, and throttling more, but ive applied mx-4 to it, (and read reviews to try icdiamond, so have some on order). ive reseated it twice, first time with the paste spreaded using a card. (old way i used to do it) didnt yeild much better results, and intels guide of a little in the center, and use mounting to spread across the die. 5 degrees lower, or less throttling going on. is there anything that can be done to get the standard 954mhz atleast from it, or even get temps to a more reasonable level?

taiwan Posted November 27, 2014 Author Share Posted November 27, 2014 went through all the points mentioned in the sticky regarding hardware mods for cooling. opened up the vents a little more underneath (widened them). used ali tape to force air through the radiators. put spacers on the gpu mounting points to pull the plate down as flat as possible. all this has reduced the temps a good bit. with the cover off it is better again, so im still restricted on the air intake side. other than holesawing the bottom plate where the fans are, and putting a mesh over to protect fans, what else can i do? cover on temps CPU - peaked @ 69°c GPU - peaked @ 85°c cover off temps CPU - peaked @ 65°c GPU - peaked @ 79°c definitely a step in the right direction!! only problem i have now is the GPU is starting off at 849mhz, and pulling down to 810mhz. i dont think thats throttling as it happens before it gets to 60°c im running on the latest drivers. what to i need to do to bring it up to par? do i overclock? im guessing im going to be running at the stock voltage? what program can i use to find out voltages? sorry to bother you guys. just depresses me that im not getting the performance i paid for Quote Link to comment Share on other sites More sharing options...
Guest Posted November 28, 2014 Share Posted November 28, 2014 Sadly, for the 880M that kind of throttle is "normal"...You can flash the custom vBIOS to remedy this issue:http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks.html Quote Link to comment Share on other sites More sharing options...
taiwan Posted November 28, 2014 Author Share Posted November 28, 2014 ah yes, i think thats what im needing. they came from factory underclocked? bonkers!thanks for the help. Quote Link to comment Share on other sites More sharing options...
mw86 Posted November 28, 2014 Share Posted November 28, 2014 ah yes, i think thats what im needing. they came from factory underclocked? bonkers!thanks for the help.no they came from factory with the inability to maintain their stock clocks and boost clocks. They throttle down due to imposed limits on the card which is adjustable on the modded vbios. So they arent factory underclocked, rather they are factory crippled lol.

This app works better than most for our 880m allowing to control the volts, power limit and temp limit that the modded vbios allows us to adjust. The new limit if you set it can now be 93c and 160% power limit in TDP. Make sure to sync the two limits, is one of the options. Quote Link to comment Share on other sites More sharing options...

So they arent factory underclocked, rather they are factory crippled lol. thats the selling point of the card i thought, was to be faster than the previous? will look into it. never flashed a vbios, done a few bios's on towers, hotswapping etc when ive overclocked and corrupted the bios, but nothing like this. some research required 8-) doubt ill be overclocking right away, as just unlocking the standard potential of the card will feel like an overclock in itself 1 Quote Link to comment Share on other sites More sharing options...
taiwan Posted November 29, 2014 Author Share Posted November 29, 2014 ok got the flash on lol its still getting to 93°c now, but at 992mhz. theres nothing i can do now other than coming up with some extreme way to keep it cool? the air cooler just doesnt seem to want to keep it down in temps now takes a while to get to 93°c but i start to see some throttling slowely but surely. lowered the core down to 940mhz, and im bringing the voltage down little by little with nvidia inspector. down at 0.9v now and its run for an hour on furtest at 89°c with cover on, that i know is still restrictive. but when the fan kicks in to 100% it brings the temps start leveling off. been no artifacting as of yet. will find out its weak point sooner or later, and start to bring clocks back up to the standard 953mhz. think ive borked it still runs, but only gets to 405mhz now its like its on a permanent throttle. any ideas where to start? EDIT: brownpants moment over, found that nvinspector had imposed a 30fps frame limit. well, had a fright there!! more tweaking Quote Link to comment Share on other sites More sharing options...
mw86 Posted November 30, 2014 Share Posted November 30, 2014 lol well I know my 880m do stock vram and 1020core on 1v seem to stay cool enough in what I throw at it. Much higher long term temps get worse because of the needed voltage to get there. I am using Liquid Pro on the gpu cores though so stock paste may not get as far. 1.018v for 993 on the stock vbios was horrible, this mod is great having 993mhz 1volt default. I have to max my fans to stay cool always anyway as I have Haswell and it is like trying to cool the Sun... Quote Link to comment Share on other sites More sharing options...
taiwan Posted November 30, 2014 Author Share Posted November 30, 2014 ive been using furmark to test it for temps, and have read that its really not a good idea, as it pushes it right to the limits. is this a good or bad thing? lots of reviews saying dont touch the software.... i made a run of stock voltage 1v and 992mhz on 3dmark, (furmark was throttling at 93°c), 3dmark didnt even get to the last fan spin up at 90... aye i repasted both cpu and gpu with mx4 and put some more thermal pads on the, i think voltage regulartor thingy's, (cant remember their name) some were missing Quote Link to comment Share on other sites More sharing options...

I use Fan Control for my Alienware 18 through HWiNFO. If you can control your fans setting them to max while gaming would be good. If not you should be okay for gaming at 1v 993mhz. The paste I use is not a paste but liquid metal and highly conductive. It performs very well but takes practice to apply so that it is just enough and does not touch other components other than the cpu or gpu die. So for MX4 those temps arent bad. I used at one point a full version of 3dmark and set it on one test and looped it and go by the max temp i get in that after a few tests in a row. better than using furmark. a free alternative would be Unigine benchmark a few times in a row with max graphics settings.

taiwan Posted November 30, 2014 Author Share Posted November 30, 2014 nah, i cant control the fan speed. i did try through the evga precision x app, but it didnt make any changes. speedfan doesnt detect them. so its either auto or flat out. ill need to get more cool air through these vents at some point.the funny thing is, i tend not to game on the laptop much, but ive taken to make it my duty on getting it right.

mw86 Posted November 30, 2014 Share Posted November 30, 2014 evga doesnt work for mine either for fan control did you try HWiNFO im not sure if it works or not but you open the sensor panel and if there is a fan icon at the bottom of that window you have fan control. you said auto or flat out? if you have a hardware control that maxes fans id use that. definitely give a raise to the exhaust area of the laptop to keep heat from building. In game you should not hit more than 80c from the handling you described in most games that is.. Quote Link to comment Share on other sites More sharing options...
taiwan Posted November 30, 2014 Author Share Posted November 30, 2014 its on a laptop lap cooler thing. targus lap cooler, neoprene thingy with 2 fans to aid that little more. with the panel off, even furmark cant get it to 85°c now after the vbios and lowering voltage and thats the fans not flat out. but panel on it gets to 90, fans kick in and drops back to 88 and holds there. ill try hwinfo now... im sure ive already got it installed but otherwise its fn+1 flat out, and again for auto. EDIT: nah i cant adjust in hwinfo, only view the speeds they are running at. from what i can read its something of a firmware/bios restriction Quote Link to comment Share on other sites More sharing options...

You dont really need fan control having auto and flatout hardware controls anyway, i use HWiNFO to be able to set as you say Flat Out (full speed. My suggestion test with fans flat out get a temp on the same tests to see where you are at then go from there if you want. The idea is to use the least amount of volts for the max speed that will allow for the speed you are at. Each card is different but if you crash thankfully PrecisionX will let you reset everything and if you dont have it apply on boot set your definitely good to go while testing. Vram high will effect heat dramatically on our *gb cards and 880m combo simply because a certain section gets hotter on the card from factory then 780m and the likes at same speeds etc. If your real worried about heat stick real low on volts such as the 1v or maybe as high as stock 1.018v for gaming but since that original voltage was too high 1v at something over 1ghz core would be a good bet. Maybe 1.006 or 1.012v but as you go up temps go up more than simply raising the mhz... the volts are only to keep the mhz stable as you see. Depending on the temps you get flat out fans on those tests you can probably go a bit higher on core and a small vram OC. For bench numbers a lot use 1500mhz on the vram or higher but for a daily clock on the temps we are dealing with if you use one I'd recommend trying 1300-1425mhz vram. Going too high over what the vram can do long term since you cant raise the volt of the ram easily you will cause the error correction to kick in which will allow in a lot of cases to complete a bench test but it degrades performance when that starts so if you start to raise vram to a point and scores start to drop thats near where error correction kicks in because it is needing more volts than is being supplied. Have fun buddy. 1 Quote Link to comment Share on other sites More sharing options...
taiwan Posted November 30, 2014 Author Share Posted November 30, 2014 the evga app wouldnt let me adjust the voltage of the card. only nvinspector is allowing me to, and its simple enough to set it as a startup task to set the clocks and voltage. i had a couple of crashes, at 0.9v, but im up to 0.925 @ 941mhz and seems to hold at the temps above. wouldnt mind to be able to run at the intended boost figure of 993mhz lol. ill give it a run now with the fans at max with the panel off, and see how it does. and thanks for the help! very very much appreciated if i didnt live soo far away, would buy you a beer! and a thanks to prema for the help too! and to svl7 for the custom bios!

mw86 Posted November 30, 2014 Share Posted November 30, 2014 you are welcome and it's always great just to help glad I could be of some assistance. Nvinspector is perfectly fine as well. Okay keep working up until you seem to notice the temps jump more than they were per mhz you have raised. When you hit that point stick to the volt and mhz that was handling very good last. I think based on what you have reported you should get atleast the stock clock 993mhz at a low volt i forgot to say if you start to raise vram the volt needed on the core may need to be higher youd have to test because the more bandwith from the vram the more your core can work at the same speed or is pushed is basically the result. So my 1020mhz core @1.0V may need to be 1.006V @ a decent overclock on the vram. Vram and Core dont directly effect each other in their handling but because it can help the opposite do more at once the volt requirements can go up. So if you add speed to any component it may need more than what overclocking one component of the gpu needed. Temperatures if temps sit very high for long term the volts required can slip up an increment but you know that because you are testing long term temps. When done definitely load up your most modern game to test long term temps and real world scenarios vs tests. if your right click the top bar of the gpuz window you can select ASIC Quality that will tell you an estimate of how efficient your gpu may be, may is key word because some with low ASIC numbers can still do great but they usually require more cooling. The idea is the high the number the less volts at the same mhz would be needed and the lower may get the same mhz but need more volts and will need to be cooled better due to the higher volt requirements. here are my pair of 880m Quote Link to comment Share on other sites More sharing options...
Guest Posted December 1, 2014 Share Posted December 1, 2014 Furmark is the best way to send GPUs to their grave. The 93c is actually the vBIOS limit. There is an experimental version of NVIDIA Inspector that removes this limit...with that Furmark would bring it to its knees... Quote Link to comment Share on other sites More sharing options...

Thanks Prema :awesome: never knew there was a way to surpass that limit. Yeah I never user furmark I stopped using that program back in 2011. Agreed it is unrealistic load compared to games. So wait is there a way to surpass the power limit )) I monitor that in OSD ie higher than 160% or remove the limit? Quote Link to comment Share on other sites More sharing options...

Maybe I can bench over 1200 core on my 880m, I usually hit the 160% limit not the temp limit. Thank you Prema. Quote Link to comment Share on other sites More sharing options...
