Hi all,

Just bought a retail Athlon XP 2000+ so that I could use my old Athlon XP 1600+ in a second system I'm building. Running an Abit KG-7 RAID mainboard, lots of toys, latest BIOS, very stable. If I put in the XP 2000+, everything goes to hell in a handbasket. Windows XP locks before fully booted, or gets blue STOP errors, every time I boot back up, CHKDSK finds crosslinked files and incorrect filesizes, etc. I'm running an Enermax 430w PS, so that should be okay. I set my RAM timings ultra-slow, scaled back my AGP settings to 2x with fast writes off, turned off caching the system and video BIOS, and turned of IDE block mode and prefetch, still nothing. I've tried both using my Alpha 6035 HS/Fan, and the retail AMD hs/fan (which I don't think is as beefy, but clips tighter), temperature doesn't seem to be getting out of hand. Even underclocked the bus to 100MHz to see if that solved the problem, and it does not. Cannot even boot in safe mode with the 2000+ in, put the 1600+ back in, all fine.
Anything I haven't tried? Possible that I actually got a CPU with problems (I know bad cpu's are rare)? Appreciate any help y'all could offer.
