Flashing the 5900Ultra to a 5950 Ultra.

[sev]

I recently purchased a Gainward 5900Ultra Golden Sample (1600XP model) with 2.2ns RAM on it. I have over clocked it with powerstrip to 500Mhz and 900Mhz on the RAM.

Im tempted to flash this puppy to a 5950U.

Has anyone done this to such a card yet and if so, what are your experiences? (artifacts, overheating, sucesses, failures?)

Thanks!
