video card wigs out if I go above 144fsb. help please?

[griffin]

I am running my p4 1.6a on a asus p4b266-c with a pny geforce3 ti200 (Win2k). Currently I am at 144fsb, and 1.575vcore for 2.3Ghz. The max I can get on my video card is 228/490 which then posts a 3dmark2001 score at 7539 (stock vid card settings posted 6011). I tried to bump up the fsb to 150, and the fps in the first benchmark test was 1 to 2 (i forgot to look at the official results at the end)! I let the benchmark complete and the score to my surprise was 511.( i thought it would be lower).

Does anyone know why I can't get above 144fsb ? Also, I tried running my video card at stock speed and the same thing happens in 3dmark, so it isn't a result of vid card o/c'ing...

Anyone ?

thanks.

On my system in the past, when the fsb was raised above 160MHz my video card has gone beserk. I finally figured out that it was actually my memory timings. The computer would appear to be stable in everything, but when I ran 3d apps it would screw my Geforce 2 Ti 500 bad, even at stock speeds. I lowered my memory timings some and now I have my video card at 290/520, all is well. Also some of the earlier Detonators (I was using 8.03, 23.11 now) choked at anything above 150 on my system and did not support fast writes.
