X1800XT PE bios flash

[gobucks]

I have a sapphire X1800XT 512MB card and yesterday i flashed it to the XT PE bios with clocks of 700/800. everything seemed to be working fine - 3dmark06 ran with no artifacts at all. except that after about 2 hours of gameplay i started getting a messed up display - a noisy checkerboard effect on my screen. when i left the game the problem went away. anyways, i'm told that the non-PE X1800XT's lack some mosfets for voltage regulation, and that they cannot provide steady voltage needed for those speeds. so anyways, i need to flash it back but i did not dump the old bios in the process of flashing it. does anybody happen to have a copy of the old bios (625/750)?

Go here to download any bios you like:

You might want to check your temps after gaming. Download ATITool and log the temps. Even with an Artic Cooler, my x1800xt pe gets to 70degree C before that, the oem cooler got me to 78 degree C.

It's a good practice to backup your original bios before flashing. Glad that you find one.

No problem. I found that the XTPE bios didn't give me anymore speed. chip was running hot already. I just use the ATI overdrive util to take it to 700/1600 (around there) when running 3D apps.

sweet, i flashed it back and everything is working normally again. i can even go back to my old overclock of 655/774 without any issues (yeah i know the overclock sucks, but it's the best i can get).
