Also I guess it really doesn't matter, I maxed voltage @ 1.381 and couldn't get any more on memory or core than @ 1.293.

it is not raelly safe to put the slider all they way to the right since that much voltage overtime will kill the card. i would say maxed should be 1.3 to 1.35 depending on how cold the card is

64%, probably the reason I don't see good clocks I literally hit a wall right around 1220 on the core and 1750 on the memory.

Right click on gpu-z (menu bar )and then click on asic quality, and also yuor gpu stock clock is at 950mhz, switch the bios to the second position youll have better overclock
post #29 of 67
Does the second position BIOS only just change the clocks or is it something else? I mean would I see better #'s from the second bios than the first assuming i'm not just leaving them @ default clocks.

What do you mean by better overclock?

Only difference is (how i see it) that 2nd BIOS is overclocked more? (I might be wrong, i would like to know this as well)

From:
http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1463&psn=&lid=1&leg=0

" Dual BIOS switch allows users to select the higher performance settings of 1GHz core and 1450MHz memory, making the fastest card in its class. This setting also uses a more aggressive fan profile and raises the limits for maximum overclocking. "
