Very weird overclocking problem

[RMD2000]

This is system:
T-bird 1000(not overclocked)
Abit KT7-RAID(optimized settings)
Creative GeForce GTS 32mb(retail).
2 X 128MB Micron chip(generic sticks) PC133 at CAS3
SBLive
2 X 30Gb IBM ATA100
WinME, DX8.0

Without overclocking system is very stable(either 3D Games or any other apps).
When I tried upping FSB to 110 system booted perfectly at 1100(110 X 10) and was stable until I tried playng UT. Then I tried Quake, then NFS4. And every time the same problem - horrible pixelation. I don't experience any crashes or problems, just can't play anything.
All drivers are up to date(for video I tried Nvidia drivers and Creative, the same problem).
Here is fun: I reduced FSB to 103 - the same! CPU temp is 44C
I reduced FSB to 101(boot at 1010) - the same!
Back to 1000 - now everything is working.
Just curious - no overcklocking for me???

Thanks.

If it's unstable it means it overclock to high. Maybe try to up the voltage a bit.

FSB, it has caused the downfall of many a system, especially a 1Ghz System.

Have a very similar system. Think you may be running into memory problems.
If your CPU is unlocked, try to boot at 10.5x on the muliplier.

I found >108Mhz gave me bad video artifacts too, think it's OCing the memory too much.
