Hi all,
I'm looking for some advice here on how to get a stable overclock on my GTX 980 SC. I've read many articles and posts about people being able to achieve 1500Mhz OC'd from the normal 1367Mhz boost clock that this card comes with.
I am using EVGA Precision X to overclock. Using Valley benchmark I can get it to run artifact free at about 1440Mhz. If I push it any further than that I get artifacts during benchmarks which is an obvious red flag. However any game I run crashes within 5 minutes even if I overclock just a bit.
Do I just have a weak card as far as overlclocking, or am I missing something?
I've tried raising the power target to max (124%) and leaving it at 100%, or somewhere in between. Doesn't seem to make a difference. I've used fan curve settings to be sure it doesn't go above 80 degrees C (usually sits around 65-70).
I'll start at +13MHz to the boost clock and go up from there in 13MHz increments. As I mentioned above, benchmarks are stable up until I hit the +78MHz area, then I start to see artifacts. The lowest I've tried with in games is +39MHz and even then, any game will crash pretty quickly.
Is there a trick with the voltage settings? I have played around with that a bit, but I'm not entirely sure what it does.
My CPU is an i5 4670K running at 4.4GHz. This is overclocked in my bios but it's completely stable. Could that OC be affecting the GPU stability some how?
I really appreciate any advice here! Fairly new to GPU overclocking.
Thanks!
