Hey everyone, upon reading lots of articles about BIOS on graphics cards i actually found that my card was just a slowed down version of another one by the same manufacturer. Being curious i looked furthur into this and found everyone i asked with experience telling me that it could indeed run at higher speed easily as it was indeed just slowed down.

My graphics card is a Sapphire Radeon 9550 256Mb DDR AGP 8x.
The card that it is a slowed down version of is Sapphire Radeon 9600XT 256Mb AGP 8x.

So, me being me looked into flashing the BIOS to the 9600XT model, which to my surprise i found that others had done at a 100% succes rate, so long as they got the correct BIOS. So, i went and grabbed the Sapphire 9600XT's BIOS, and backed mine up.
I looked into flashing and found it relatively easy and built myself a bootable CD from the ISO they supplied (with the 9600XT's BIOS already on it)
I flashed the BIOS and Windows picked up my card as a 9600XT.
I was amazed.
It should now run at 400/300, but i keep having artifacts, or, what seem to be artifacts, and after a minute they vanish.

Does anyone know of a solution ? As this even happens when i clock my card down using ATItool, all the way back down to 9550 speeds.

Let me know if you want any more info.
Looking forward to your responses...
