unlocking 16 pipes on R420 chip Powercolor ATI x800 Pro Non Vivo
Hi all I want to flash my bios and unlock the 16 pipes in my card if I have them.
I have read a few different ways of doing it but unsoldering parts can be touchy and just flashing a bios sounds more safe.
I pulled out my Powercolor x800 pro and removed the Heat sink and had a look at the GPU under the heat sink to see what it had written on the GPU, there was:
ATI Radeon x800
215RAACG11F
GCO5541
0429AA
TAIWAN
My graphics card is not a Vivo card Sticker specs on the graphics card was R42-PD3B
PowerColor Radeon X800 PRO 256MB R42-PD3B 256MB AGP 4x,8x CRT, DVI-I & TV-Out
(This Card is my card)
Link to all ATI cards Here:

After that I installed RaBiT v2.2.0 and opened the backup bios from Atitool I made. When opening the file it come up with the CRC error then I saved the file in .rom and .txt now I followed your instructions and went to 0x000007A in hex editor on that point it had (2000) so the 2nd value was allready 0 = zero pixel pipeline quads disabled (16 pipelines enabled) so I did not have to change it.
(Hex editor BIOS text file here)
So is this be right?

This is the second revision of the Powercolor X800 GT bios, but modified to be identified as a Powercolor X800 GTO with an R480.

Sorry do not know if I have 1.6ns or 2.0ns ram chips on the card. I can not tell as I have heat sinks glued to my ram chips on the ATI card but I do know they are samsung ram chips.

Any info on this would be ever so grateful
