MSI 7950 Twin Frozr overclock becoming unstable after 6 months?

post #1 of 6
Thread Starter 
Hi All,

Like the title says I've had my video card for 6 months now, I did a mild overclock and set the core to 1000mhz (up from 880) and the memory to 1375 (up from 1250), I left the voltage at stock, the slider in the power control in overdrive is at 0%. When I first overclocked it I had run 3dmark and Heaven to see the before and after results multiple times, I've since logged in many hours in Crysis 1 and 2, Borderlands 2 and most recently Farcry 3 with no problems.

Yesterday while playing a game which really doesn't stress the GPU, world of warcraft, all the sudden I started getting severe shadow flicker and black artifacts all over the screen. At first I tried to restart the game to see if that would fix it, no go, so I restarted my computer and reset the video card back to default clocks and the problem went away. The only thing that's changed recently was updating my drivers to 13.2 beta 3, I did a clean install like I always do, I actually use the guide here on this site.

My question is can an overclock become unstable after that amount of time? (6 months) Should I keep it set at defaults and be happy? Do I need to adjust the voltage control to 20%? Is the card going bad?

I don't want to damage my hardware, so I don't like messing with voltage usually, I had thought with a mild overclock it shouldn't hurt anything but maybe I was wrong. Any suggestions or thoughts on this would be appreciated.

Thanks

sometimes the beta drivers could have some stability issues. but most users have found the 13.2 beta drivers to be quite stable. max out power control to +20%. that allows maximum power to be supplied to board. voltage control is different from power control. voltage contol is available only with 3rd party apps like sapphire trixx or msi afterburner. so don't worry when using AMD Overdrive in AMD CCC you are only overclocking at stock voltage. see if you can run 925 mhz stable. test with benchmarks like heaven 3.0, 3d mark 11 and games like bf3, crysis 2 , farcry 3. then bump it to 950 mhz, 975 mhz. find which clocks are stable.

gokumhz....really interested in your findings and results with your MSI TFIII 7950. I too have the same card but I am still on 12.11 beta drivers. My 7950 default at 880 mhz @ .993v. Wondering what your stock voltage is????? Also, are you using MSI Afterburner??? With the new 13.2 beta drivers...many OCN users are stating to make sure to delete the 12. 11 CAP which is already included with the new beta drivers.

I've been running the card for a few days now at 975mhz core and 1375mhz memory, I upped the slider in power control to 20%, I've run heaven and 3dmark a few times, and also been playing Crysis 2 and Farcry 3 without any problems.

I do my overclocking in CCC, I don't use afterburner for overclocking, only for monitoring temps and frames through my LCD display on my keyboard. When I upgraded to 13.2 beta 3, I uninstalled everything including the 12.11 caps as it was stated that they are included in these drivers, and yes my default voltage is 0.993.

Thanks again for the help, I'll keep you posted if anything changes.

can you confirm that with the 13.2 beta drivers you are capable of still adjusting the voltages in MSI Afterburner. I know you stated that you utilize CCC for you overclocking. I just need to know if the new AMD beta drivers did anything to change MSI Afterburner. Preping rig for Crysis 3. Thanks.
