PCI-E X800 Pro Vivo -> XT flash ... Seen as x800GT ... help!

[Superguy]

Hey all,

I was trying to flash my PCI-E X800 Pro VIVO tonight, using the latest Cat's and everytime I flashed it to an XT bios, Windows would detect it as an X800 GT. Still had 12 pipes enabled and X800 XT speeds (my card won't do XT PE speeds). Nothing.

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?

Thanks,

Super

hi,


Try forcing it to install the xt, or xtpe driver, i put some steps below if needed:
First download all drivers you will need. Do a clean uninstall of the drivers, by first uninstalling the drivers from the control panel. Install and update drivercleaner. Then restart in safe mode (Admin) and use drivercleaner. Then restart computer, make sure no internet connection. Then install the drivers, make it install the appropriate xt, or xtpe driver (this may, if there is some conflict, cause windows to become unusable, so proceed carefully, after all these mods are obviously not guaranteed to work). Afterwards, reboot and then check again the number of pipes.


I have the exact same card, pci-e (is your card BBA?), and tried to flash this (x800 pro 16p) bios (flashrom -f -p 0 newbios.bin, you're using the modified flasher right?), and my computer display would not appear. I had to flash blind back to my old bios (x800 pro 12p) before it would work. I haven't tried the x800xt or xtpe bioses yet.. I will though and report back. Did you have this same problem with the x800pro 16p bios?

Anyways, how did you find out what speed your x800 pro could handle (ie. you said your card could only do x800xt, not x800xt pe? I assume you might have overclocked it to the stock speeds of the x800xt, xtpe to see if it was stable.. If so what speeds did you check?

I will try to find out more on w1zzard's theory, technically we could find out by looking under the gpu heatsink to at least see whether there is a laser cut...=/

Here's some of my discussion with someone on the techpowerup forums.

How come on this thread he says that for those who have succeeded in hard-modding their x800 pro and activating the pipes, have 100% success? I did take notice that there were very few successes overall tho =p, and I assume that he hasn't updated the thread in a long while since it is very old. I will try flashing the XT bios once, to make sure, I've tested my card at 500/500 and it seems okay...

I also asked him for the difficulty of removing the heatsink to check for the laser cuts//

lemme know of your progress, anything else, if u think i should ask him something else or something

thanks,

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.
