Don;t have VTT setting in bios so i guess it's at auto. ok, i've rolled it back to 1.42v (real) @ 4.4ghz stable for my 24/7. (TBT)
Benching i'm going to go for more tho, 4.75 isn;t fast enough i need more HWBot points.
oh... another ghetto factor, you can't see it in the phot'os, i had to put selotape on the edge of the ocz cooler to stop it conducting, it actualyy bends the 4580 downwards, touching the back of the PCB, i've already taken one of these cards back i'm trying to keep this one. but it'll bench at 750/1200
