[GTX 960 SSC 4GB] keeps reverting back to stock GPU clock at high load

post #1 of 7
Thread Starter 
Other specs: Windows 10 x64, AMD FX-4100, GTX 960 SSC, 16gb RAM, 500w PSU, Asus M5A97 evo mobo

Hey guys! This only happens like in a game when there is high load, like when there are a lot of characters on the screen and/or a big battle with a lot happening at once. It stays smooth and fine most of the time when I'm just doing normal things. I have tried both Precision X and MSI Afterburner. I have my card clocked to 1500 MHz and the default clock is 1278 MHz, and that's what it keeps dropping to during times of high load. It will then slowly rise back up again when things calm down on the screen. Can anyone tell me what's going on?

C'mon man, no one has any insight or advice? No one wants to help? I've posted this in like 3 different forums and no one has a reply.....

Are you getting any PerfCap messages in GPUz when this happens? Have you checked for thermal throttling and thoroughly tested your GPU OC? Is GPU RAM being exceeded?

No messages or thermal throttling. Temps stay at a constant ~50C. I have tested my OC by running unigine valley and having no issues there. I have not run an extensive test yet. How do I know if GPU RAM is exceeded?

My version of Precision X has a performance log you can open up and see all the parameters of your card and log them as well. It will also show GPU RAM usage. If it is maxing out your RAM it will show in the graph. I've never seen a GPU OC cause the GPU to drop the clock and then slowly climb back up to normal OC clock. It has to be some kind of throttling. Thermal, power something along those lines. Could it be PSU? You said you had 550w but not what kind of shape it might be in.

Edit.

overclocks aren't guaranteed, you have it set to 1500 but its reverting to 1278.. sounds like the card can't pull enough power to be stable at that frequency. try backing down your overclock some. Even in overclocks that are game stable some apps like 3dmark can put such a strain that cards clock down whatever is game stable, if games are enough to drop you back down to 1278 than it sounds like the chip is good for what its rated on and maybe cant go much further.

have you tried other clock speeds?
