I have a 9700 xt which I successfully flashed bios to 9700 pro bios. Using AtiTool I have it running at 360 core speed, but the memory wont go over 266 and be stable. I know form researching the forums, that this card has infineon memory chips, which are not as good as 9700 pro chips. Is it feasable or practical to try to change chips on this card? Any input would be appreciated.
