View Full Version : Need help with 6800 Ultra Bios Flash

09-13-04, 02:55 PM

I have an xFx 6800 Ultra that came stock with the bios. I was having occasional lockups so I decided to try the Omni Extreme Edit 1.5 utility with the latest bios. I used nvflash 4.42 -p -u -f -2 to flash. I noticed that Omni Extreme had strange values for the 3d clocks 11XXX so I changed them to 425/1200 like the 2D. For some reason after I flashed the 2nd or 3rd time, windows now detects the clocks as 446/1.26 for 2D and 3D at default. This is not right as I reflashed the default xFx bios which was set for 425/1200 on 2D and 3D and version It seems as if the clock settings are not getting changed now or Omni Edit changed the wrong registers and now screwed my card up. I tried flashing with nvFlash 4.42 and 5.08 the stock xFx 6800ultra bios and still get 446/1.26 for the clocks. I even tried a fresh install on Windows and get the same thing. Does anyone know how to completely wipeout the 6800Ultra bios so I can get rid of the registers that omniedit must have messed up and reflash the bios it came with? It seems as if the clock changes are not being picked up when I flash but the new bios version shows up in the display control panel.

Did you read through the two stickies on 6800 random lockups and BIOS information located at the top of this forum?

If you have a "good" bios saved you can run nvflash and use the -e command. That will completely erase the bios. Then simply flash it with the "good" bios that you have saved.

NOTE - I have never used the -e command to erase a bios so don't come to me if it messes your card up.

Yes, I've read the top 2 stickies and didn't come across any problems like this one. I am trying Warden's suggestion now.

I tried Warden's suggestion with the xFx default bios I downloaded and got the same results. 446/1.26 for the defaults. Anyone know if wfflash with work with an xFx card?

Something weird is going on here, perhaps there is some sort of flash "lock" or something of the sort? I can not get the clocks back to normal by flashing any of the bioses. It doesn't matter how they look in omniextremeedit the end up being 456/1.26 default. I did manage to get it to flash to 420/1.15 with a bios which is supposedly set for 400/550. I have no clue what is going on here. It doesn't make any sense at all. I mean I can at least manually set the clock and mem to what I want with coolbits, but the default settings are all messed up. Has anyone else seen anything like this? I have no clue what the voltages are defaulting to either, because none of the other settings seem to take either. The only thing I notice is that the BIOS version does change in the forceware control panel.

Help me guys!!
