I started to try and push my XFX 7970 DD 3gb card with a more aggressive OC today. I started out using the 14.2 omega driver, and CCC to push it to around 1150 on the GPU and 1525 on the ram. Every time I go past 1050 on the GPU and 1475 on the ram I get artifacts sometimes, not all the time. Anything past that for a OC and I get MWO crashing....well kinda crashes. If in game the screen goes black, and I can still hear all on Voice chat, but have go to task manager and shut down MWO and then restart and rejoin. Some times I get a graphics card driver has failed error, and it shuts down firefox, and the game just crashes out completely. Temps are not a issue, and stay below 75C all the time and avg around 60-68C even while playing MWO with the card OC'ed.
So today I uninstalled the 14.2 omega driver and restarted, and installed the 15.3 beta omega driver. I also have now installed MSI afterburner to do my Overclocks on the 7970 now. I have the card completely stable at 1103 mhz on the Gpu, and 1603 on the ram, with a 20% power increase, well....in any other game so far I have played today, other then MWO. I have ran benchmark stress testing with Intel's software on the card, I have ran benchmark performance test in Dawn of war II Retribution, I have ran benches in Aliens Vs. Predator, and several other games, and all have passed and completely stable with this higher Over clock on the 7970.
I had not up till this point run the repair tool, and made sure the clear shader cache was checked.... as I am doing that right now. Would this be a issue or the reason for problems that I have explained in this game? Anyone have any thoughts or advice on this? I am still running the repair tool right now, and waiting for it to finish.... hoping this will solve the problems I have experienced.
