I was fooling around with it again last night. Still no go.
The Mobo has the latest Bios (F8) and if left to it's own devices it merely id's the CPU as an AMD Athlon at 1050 and uses 100 for the system bus.
It runs fine like this, maxing out around 44C when playing AH.
If I use the mobo dip switches to force it to a 133 system bus speed, it will id as an AMD Athlon XP 1600+. However, it will run up to 55-66C when playing and the game seems to get "choppy" on the video when it gets that hot.
I used the AMD CPU ID program to examine the chip and emailed the results off to AMD tech. I bought it from Googlegear and it came in a sealed 1600+ box.
Heck if I know. It's only worth about $50 as a CPU anymore and I'm about due to upgrade into the 2000-2200 range anyway. Probably will after Christmas. Then I'll just stick it in my son's computer at 1g.
