I'm trying to determine the best overclock for my reference 7970 memory and I'm trying to use FurMark to do so. Is there another program that works better? When I run at 1650Mhz I get the same fps as I do at 1750 or 1800Mhz, so I can't tell the difference. I know that usually you go up until you see your fps begin to drop and then back down 20Mhz. What program would show fps dropping for memory clocked too high? I don't think Furmark stresses memory very much.
