Hmmm, I flashed with Vcore set to 1,327 but I can't get GPU stable at more than 750MHz. At default Vcore (1.21V) I get 730MHz stable. So it's just 20MHz. I doubt actual Vcore is 1.327V, and now I see it's just 1.24V? That explains why I got just 20MHz and why the temperature stayed almost the same.

I saw some of you entered value manually, but that doesn't work for me.

OT:
A question for lowtcell: how did you get a limit of 900MHz for GPU in CCC?
I used HIS IceQ3 Turbo bios edited with the editor app. If you look at the screen cap of GPU-Z, you see it reports the card as a HIS now (my card is Sapphire). I only raised Vcore to 1.241 and CCC still works with that. All other Bios I tried either killed CCC or left max OC @ 720.
