Sapphire 7950 Boost.zip 41k .zip file

Hope it works, let me know biggrin.gif

*Edit* Apparently I was wrong, Just tried to OV to 1.3 using trixx and the Voltage at load in GPU-z didnt change at all. Lame


I know my HIS iceq 7950 is unlocked, it is non boost however. Pretty sure the max allowed V is lower also. I have mine manually OCd to 1100 at less than 1.2 V. Anyway if you want to try that bios let me know. Sorry mad.gif

A new couple 8pin would be better than these I think... But I'm not sure, these PSU's output ports are in standart?

I'm using 775W Thermaltake Toughpower XT

I've seen this question asked before and I've looked around a little but I've never seen a definitive answer. With dual Crossfire, should you use two bridges or just one? If just one, does it matter which slot you use?

use one bridge, and the first one for crossfire.. the second one is used for if you add another card. smile.gif

BTW by "slot" do you mean the bridge fingers?
