I have been looking around to see if it is is possible to flash my X800XT (R423) to the X800XT PE bios and essentially then have an x800xt pe card. If anyone knows the answer please do respond. Also, if possible with this change the voltages so overclocking will be easier? Or will I have to voltmod? I recently Ordered an ARCTIC COOLING AVC-AT5 Rev. 2 cooler for my x800xt so I cannot wait to overclock to the max. Thank you for any time and consideration you put into your posts.
