7970 crossfire OVERCLOCKING

post #1 of 3
Thread Starter 
Quick question: Has anyone found a way to overclock both GPUs past 1125 while in crossfire mode?

I have overclocking unlocked in MSI afterburner. On GPU1, I can select whatever I want for the GPU clock and mem. I can get GPU1 up to 1225 stable. But when I switch to GPU 2, it is locked to 1125 and that slider is maxed out.

What gives? I can overclock GPU1 freely but GPU2 is stuck at 1125. Help frown.gif

I love the 7970 crossfire btw, only game that doesn't work well is Batman: AC. But in every other game i'm getting near 100% scaling in xfire! Pretty awesome.

You probably need to disable ULPS with reg edit.

Test each card by itself to know the limits of the card before put them in crossfire. Do not select "sync...." in Afterburner settings. Use the "reset" button.

 

 

Install MSI Afterburner 2.2.0 Beta 11

 

Turn off ULPS;


1. Go to regedit (start > search programs and files > "regedit").
2. In drop down menu: find file > type "enableulps".
3. For ALL instances (keep pressing F3) change the "1" value to a "0".
4. Reboot PC.

 

Enable; HOW TO: Enable UNOFFICIAL overclocking mode in MSI AfterBurner

 

Note: Install Afterburner 2.2.0 Beta 11 then and disable ULPS then enable "unofficial overclocking" . Exit CCC and Afterburner prior to editing. Do not activate CCC Overdrive afterward or whatever set will be reset to default. Also do not install Catalyst over Afterburner or it will be overrided by CCC Overdrive.
