Hi, i have a problem with crashing 3d applications (especially 3d mark 2001 se) and games on Windows XP Pro 32 bit .

The problem arises when i set in bios FSB 200MHz for cpu (factory preset) and set memory Frequency - Auto (200Mhz). RAM is in dual channel.

1. In 166MHz FSB everything works good but CPU is not recognize correctly

2.When I leave only two sticks of memory (non dual) and set 200 MHz FSB and 200 MHz RAM, Also works ok.

I check RAM and run memtest (passed). Swap to another sticks - same problem.

I built a computer based on that specification:
AMD Athlon Xp 3000+ 200Mhz fsb AXDA3000DKV4E
Abit NF7-S
3x1GB RAM DDR 400 (GOODRAM)
GeForce 6800 GT 256 MB
PSU - I try: Ocz Fatality 750W, Yesico 420W, xclio 650W

Also i check another mainboard: Soltek sl-75frn2-rl, another GPU and there is the same problem
