there are two pins/contacts in the upper right corner of every RADEON X800 PRO graphics chip that seem to be cut. Re-soldering the contacts and flashing the RADEON X800 XT’s BIOS is really supposed to bring the rest 4 pipelines back to life if you are lucky enough. However, sometimes it does not work.
Not All RADEON X800 PRO are Mod-Friendly
Some RADEON X800 PRO graphics processors can be modified into the RADEON X800 XT chips, whereas others cannot, as quite a lot of unlucky experiences revealed. Even though the yields of the RADEON X800 PRO seem to be pretty fine, yields of graphics processors with 16-pipelines deserve better, as a result, only a part of ATI RADEON X800 PRO products can really be turned into more powerful solutions.
andiamo bene.. io ero sicuro
basta beccare la X800 giusta !!!
