I have put the slider up, to allow it, in afterburner, but as you can see here the VDDC says 1.200

In such cases, you need to set it via bios mod.

Upload your bios to adjust it, if you like.

But how? smile.gif i don't really understand the numbers.

is there any way to get over 1.2120 ?

kredes; it is achieved by changing the top six bars of voltage in kepler bios tool to 1.2375 smile.gif it never reaches 1.2375 but is somehow needed to be in to make it go to 1.2120 ( https://www.techpowerup.com/downloads/2566/kepler-bios-tweaker-v1-27 )

Hi, I just bought a used EVGA GTX 760 ACX. And the card is so hot (78c running Unigine Heaven for just a few minutes with the case opened, even hotter with case closed). I cannot go through all the 600 pages here, but is there any guide for modding the bios to under voltage and to increase the fan speed. Thanks in advance.

Is the fan running fast already? If it isn't you can simply download MSI afterburner or something and increase the fan speed no need for a BIOS mod.

I am thinking if I can under voltage and increasing the fan speed at the same time, I can get much cooler temp than just increasing the fan speed. And by modding the bios, I don't need additional software when I use the card.

Agreed, simply turn on user defined fan curve option in MSI Afterburner or even EVGA PrecisionX, adjust the curve to your liking, and hope it solves the problem.

Another option, could be that the card might need a new application of thermal paste (myself, I've never had to do that on a card before, except for the one time many many years ago installing an Arctic Cooling VGA Silencer heatsink on my old Radeon 9700 Pro. But its an option to look into as well.


Unigine Heaven, that 78C, was that after it was running a while (warm up runs before benching), or from a "cold" start? I know Heaven can heat up the cards a bit when run, especially after some warm up runs, and depends on the settings you had enabled too.

When I was running my MSI 760 with its Twin Frozr cooler, it usually ran in upper 60's at most, for most games, but even Unigine after running some warm up runs, before doing the actual benchmark run, it did get up in the high 70's a few times as well.

Furmark/Kombustor, are even more taxing to say the least.




But another problem with that particular card, even though it sports a similar style cooler to many, including the MSI competing cards, is that with the ACX cooler for the 760 at least, not ALL of the heatpipes on the heatsink actually touch the GPU core, only the two primary larger heatpipes do, and the smaller thinner one, merely bleeds heat off the aluminum block their embedded in.

http://forums.evga.com/GTX-760-ACX-m1963813.aspx

Its not like say the MSI Twin Frozr heatsink, where all the pipes are in contact with a nickel plated copper base plate that touches the CPU, then sandwiched between the base plate and the aluminum heatsink/fins.

http://www.vortez.net/articles_pages/msi_gtx760_twin_frozr_gaming_review,7.html

So it could be a combination of things, automatic fan control needs to be enabled, or user defined fan curve enabled and set in Afterburner/Precision, could be in need of new thermal paste applied, or could just be running hot normally because of the quirky ACX design cooler EVGA implemented on the card.


Luckily for me, my EVGA 980 Ti SC+ ACX 2.0+ card I moved up to, they redesigned the ACX 2.0+ cooler design, far better design, contact area, and more heat pipes and such, then again, its a more beefier, power consuming card, so really needs it too.
