I did the bios thing and it went verry smooth I thank everyone for the instructions

A few questions thou,

when i fist used the ATI HD2900XT.bin version, GPU-Z showed that default GPU 743 and VRAM 823,but rigth above it the readings were 505/511.

Same info under AMD GPU Tool.2D and 3D clock speeds. I gues its normal

so i tried the Sapphire HD2900XT.bin(newer version than the first one) reinstalled CCC 7.10 and now i've got 743/823 on both,current and default. BTW, with the first bios, altough it said that the default clock was set to 743/823 when i played with the settings under AMD GPU, everest reported that i had actually OC the card

Also, ATItool did not launch at all. But as stated above, once flashed with Sapphire XT, everything seems to be normal now. Or am i just kidding myself

3D mark scores before and after the flash didnt change at all(with the first bios)i coulndt get a score over 7000,stuck at 6980. I know that the overall performance of the PC effects the result,but still it should've done something. Now i can only get around 7080. Oh and befor i forget, i cant seem to get ATI overdrive to appear under CCC. I'm assuming it's cause of the 6+6 pin connectors, but i made one my self last night and still no overdrive.Any suggestions for this,other than buying a new PS?

System specs:
Intel Pentium D930 3.0 no OC
Asus P5K-SE
Corsair XMS2 4-4-4-12 2T 677mhz
Sapphire 2900pro@XT
Silver power 480W ps

Now, how could i improve my 3D mark 06 scores?
