flashed the cards with the pny bios went flawlessly, everything working ok, but get lockups in 3dmark if i clock any higher than what they were at with original msi bios, 696 core /886 memory although the autodetect optimal frequencies goes higher than it did and detects optimal frequency for core at 687 wher it was 670 i think with msi bios, although you can test core settings up to 740 on core and 916 memory and it passes the coolbits test but in 3d mark just freezes, i'll keep it with this bios for the moment but it does not improve the clockability at the moment
