R7970 Overclocking issue - Page 2

post #11 of 13

Yes, I have been logging with Aida. I got plenty of logs, and it seems that the GPU gets all the voltage I provide in MSI AB:
Version AIDA64 v2.20.1800
CPU Type QuadCore Intel Core i7-2600K, 5000 MHz (50 x 100)
Motherboard Navn Asus Maximus IV Extreme
Grafikkort AMD Radeon HD 7970 (Tahiti) Video Adapter

Actually today I downloaded the latest driver from Gigabytes homepage, which improved my overclocking and results a bit. Furthermore the driver recover better when it crash. My best overclocking today http://3dmark.com/3dm11/2767798 which feels like the limit of something. Now I feel that the next step must be to up the memory. It get so unstable when I go above 1685mhz on memory.

My AMD Card does the same thing as yours. If I OC too far it will freeze for a bit then flash to the desktop and say the driver had stopped working but has recovered. Its just an unstable OC, trying adding a bit of voltage. If that doesn't work youll need to lower the core clock a bit.

Yeah, I can see that lots of us share that same behaviour.

  • Freeze and flash to desktop: Driver crash, - too much or not enough voltage.
  • Horisontal lines all over the screen/Freeze: Memory unstable, maybe also wrong voltage.


What I find strange is that lots of other HD7970 owners gets artifacts when reaching their limits, but not always driver crashes. What can be the difference? Is it chip / pcb/ cooling / bios / driver related that some of us gets this other behaviour?

BTW: While messing around with it, I have archieved 1348Mhz on GPU and 1724MHz on memory, archieving P11.217 in 3dmark11, with no graphics errors link, screenshot, and I am not using any tesselation cheats. It gets pretty unstable beyond that area. I will have to try another bios, eventually ASUS OC bios and ASUS GPU TWEAK. If it makes my OC behaviour different than what I get with default XFX bios I will write it in this thread.
