Hello All,

I have an EVGA 780ti SC 3GB with TDP issues that show up in Furmark. When running furmark 1.20.7.0 with all stock video card settings with furmark set to default of 1080p in fullscreen (no other settings changed from stock besides full screen enabled) the card will run fine for 10 seconds or so at about 75FPS and around 100%TDP then after that drop to as low as 63fps and 88%TDP. This was done on nvidia driver version 431.36 and the card temp never got above 66C. Everything on the card *looks* fine, no liquid damaged looking areas, no burn marks anywhere on the PCB or components and nothing looks broken.

Here's what I tried to fix it:
Tried Furmark 1.19
Tried Nvidia driver version 425.31 (using DDU between versions).
Tried different 8+6 pin cables.
(all these things ^ were tried one at a time, running furmark after each change)

None of those things worked. After that I decided to install and try EVGA Precision to raise the max TDP limit and temp limit to max. Doing that I got 79-83fps and 102-105%TDP in furmark with max of 72C.

Is there some kind of really low temp limit programmed into this card that drops the TDP even at low temps? Is there a specific part of this card that could be damaged causing this TDP drop issue? Any insight on this issue would be great, thanks!!

What about other Benchmark software
 
Furmark is reported as having some limits Placed by Nvidia

True, but I can still hit my power limit when running furmark, so something else must be going on with the op's card.

My EVGA 780 Ti Kingpins are in boxes right now - Or - I'd test them & post results

I just did a Heaven run though:
 
 
 

Btw that's the biggest picture I could post. Forum kept telling me it had to be under 500kb and it would not let me use imgur or imgBB so that's ^ the best I could do.

Picture looks fine to me.

+1.... your results in that pict look good. If anything run that fan at 100% when benching so you don't cook your card. Cooler it runs the better, more overclock etc.... youll get. Running it hot is not your friend. Cooler the better and 72c is NOT cool.... you want that to be your line in the sand to never pass. I use 387.92 on win 7 ult x64 with my 780 and it runs good with that driver. The newer I go the more the weird issues seem to crop up, so I removed them and went back to the best one that would let me play the newer games good and not bug my O/S out. I also do just the driver install with PhysX and pulled the telemetry files by hand and make sure I setup the nvidia control center global and game specific settings. I only use Afterburner with my card too...no Precision.

I think you're right. As you can see in the picture I posted it also does it in Heaven and not just Furmark. Does anyone know what specific components regulate the TDP and can maybe give me a breakdown of where it is on the card?

ok, thanks Sajin.

No problem.

 Do you or anyone else on this forum know how I can test the VRM MOSFETS to make sure they are all working properly? I have a couple digital multimeters.

Furmark is limited via the NVIDIA drivers and there are better benchmarks out there.
