Try powertune at +20%, if it's not already done.


Try a different set of drivers. You are most likely using 12.11 beta 4, try 12.10.

I am using 12.11 yes, how do I properly uninstall AMD drivers? I heard something about amdman.

try to oc your cpu to 4.5 and run the same games with the gpu stock.

edit: uninstalling driver, including amd, i just use Device manager. Right Click the device and chose uninstall. Make sure you CHECK the box asking if you want to get rid of all the files associated with that device. Reboot and install the new one.

I also uninstall CCC before rebooting using Add & Remove Programs.

The tool that AMD provide to uninstall their drivers is actually very good. I never had a single issue with it, even when going from AMD to nvidia.
Just uninstall them via the control panel. thumb.gif

Driver sweeper will uninstall all driver files. The uninstaller from amd is craps, does not get rid of all file. I had the proof lately as I switched from a 5870 to my 7950. The 7950 was performing like poops until I cleaned with driver sweeper and re installed everything.

You know, I'm not entirely sure why, but I got higher stable overclocks when I used Saphire TRIXX. Doesn't really make sense, I know, but it was true. I got an extra +40Mhz Core and +50Mhz Mem. I would use Afterburner to set voltage and fan profiles and use TRIXX to set Core/Mem clocks. Worked like a charm.

Oh, and regarding uninstalling old drivers... I have NEVER used a utility that worked nearly as good as just manually deleting everything. It made a legitimate difference for me.

Oh thanks for that link man, I used one for Nvidia but I didn't know there was one for AMD, will definitely be using that from now on.

I have some serious temp issues with my CPU, right now it's at stock with auto voltage and it got to 83 degrees celcius in Battlefield 3, while a week ago it maxed at 72 degrees celcius while OC'ed to 4Ghz.
I have the stock cooler which may explain the 72 degrees, but the 10 degrees celcius jump while at lower clock speed is a mystery for me.

Ok I tried that sprixx or what ever it's called, but that didn't fix it for me either.
I did capture that vertical line lock up now though.



That's what I get, and it's not always this color, it changes.

Happened at 1100 / 1575 @ 1.149V Powerlimit 20%

op, mine will do 1200/1750. But even for just 1100/1575 requires close to 1.2v for core and 1.625v for the vram. 1.149v may just be too low.

K, will try 1.2V some more and up to 1.25V if needed, see if that fixes the problem.
What do you mean with 1.625V for the memory?

What's your voltage needed if you want 1200/1750? I'm just curious.
