I have several old video boards that dont work. After a suggestion on the eVga forum, I baked the boards at 200c for 10 minutes. One of the boards (hd4890) actually seemed to have salvaged. It used not to work but now it works but shows artifacts. I am using it as "device 1" and have a gts250 as "device 0" so the display is good. ie: If i put a monitor on the hd4890 it shows green dots and other artifacts.

Currently it is running collatz but has not yet completed a work unit. Collatz will validate against a wingman so if the artifacts cause a problem then I assume I will find out eventually. Are there any other gpu projects that can validate a workunit w/o a wingman so I can tell if the board is going to work?

BTW, all the boards that had chips on the back side had the chips fall off when they were baked.

Milkyway failed - never got past 0.0 % and the amd driver reset. The driver reset occurred first which probably caused the hang at 0.0

Anyway, the board is no good. It used to be an xfx gtx280 but it failed under warranty and xfx send me this hd4890 as replacement. All together they lasted for about 3 years running 24/7.
