Guys! Good news!

I was able to reach 1050/1350 with 1.25v using Afterburner this morning. smile.gif And my temps are exactly the same. Rock-stable, nice and cool. Whisper quiet. Try doing that with the Nvidia 590! smile.gif

So now we know we can OC the 6990 exactly like 2 regular 6970. So for all the naysayers that were saying ''2X 6970 can OC better then a 6990'', it's not true. Now we know. It's EXACTLY like 2X6970 on 1 card. smile.gif

Some 6970 owners are not even able to reach 1050/1350. smile.gif

This was posted today from this thread: http://www.overclock.net/ati/968084-amd-radeon-6990-club-69.html

Hope this helps smile.gif
