Having updated the ROM to the August 05 (130), I still had the same problems. Then I re-read this, and it caught my eye. My stock frequencies in ATIccellerator II are listed as Processor 378 MHz, and Memory 337.50 MHz. So I took your advice, and underclocked down to the 9700 speeds you listed, and the problem went away. I then, slowly, brought them back up, evenly, until I got corruption again. I then went back a step or two until I had a stable display. The settings are now Processor 353.25 MHz, and Memory 315.00 MHz. Go figure... Why would my card have the higher frequencies set in it? And, will underclocking damage the card? Thanks so much for the help everyone!
