bad bios can cause artifacting?

So, my 6990 recently started behaving really erratically. Sometimes, it will artifact, but most of the time, the picture would be off. Basically, it's like part of the right side of the screen was moved to the left side, so from left to right, it would be middle of picture, then right end of the picture, then the left end of the picture, then the middle terminating on the right side of the screen. This can anywhere from one screen to all three screens at the same time. Changing ports did nothing. Swapping the active DP adapters did nothing. Reinstalling and rolling back drivers did nothing.

Then I remembered about the bios switch, and that I currently had it in AUSUM mode. So, I flipped the switch, and after 4 hours, no artifacting (it would usually occur within 30 minutes). The odd thing is, I pulled up CPU-Z, and it listed my core clock at 880 mhz with default clock at 830 mhz, so I know it's running on the backup/normal bios. Yet it's running at the higher clocks with no glitches (so far).

So... here's my question. Is it possible for a corrupt bios to cause intermittent artifacting? If so, how did it become corrupt in the first place?
 
I'm curious what the voltage differences are between the bios, if any.
 
I had the same issue; well, sort of; with my XFX 7970... I RMA'd it back to XFX and they said nothing was wrong...

Whilst RMA'd, I went out and bought a GTX680.... ZERO issues.

Radeon seems to be bad news I guess...
 
Last post assumes facts very much not in evidence. good try at the troll, but I doubt your story because you just happened to have a perfect instance of this happening and found this within two days of your arrival on the site....And that you had enough money to spend $1000 on video cards on a whim.
