Hard Mod ASUS RADEON X800Pro to XT
@ 2004/06/16Different grades of the R420 appear to be differentiated by different markings to designate the quality grade. In absence of hard information, we have to resort to the hear-say circulating that the xxx.1 cores are fully functional and can be enabled to run in XT-mode, that is with all four pipeline blocks enabled. Enabling the functionality requires a BIOS flash with the -XT binaries AFTER physically reconnecting the cut traces on the package. To give credit where credit is due, we got the idea for this procedure from this article on PCUnleash.
