It has 2.0ns RAM, but it does have the yellow audio jack and the Rage Theater chip. I followed the tutorial at Techpowerup.com, and just about every PCI-E bios for the X800 XT ... an even the 16 pipe pro bios.
Nothing would unlock those other 4 pipes.
Are there any VIVO's out there with the laser cut?
I also heard that there was an ATITool command that you could run to check some registers. W1zzard had a theory about an "f" being in the right place meant it was moddable. Anyone know where that is? I had it book marked, but that was lost when I rebuilt my system tonight.
Anyone have any ideas on how to get this to work?
Use RivaTuner.exe /rr990 . That dump return the contents of register 990 in the following bit mask format - ooooXooo. Bit three where the X is in the mask contains the count of pipe quads that were hard and permanantly disabled at the FAB.
If you have anything other than hex "f" ( binary 1111) at bit three where the X is in the mask above you have a pipe quad or quads that were hard disabled at the FAB due to a defect of a pipe in that quad.
