Overclocking ... a little help needed

[VISADE]

I´ve got a P3_500 .... no extra cooling but a big case.
It runs for hours at 560 but when I try to run 3dmark ...
well the system does not crash but it quits the program and
throws me out to the windows98 normal desktop.
What´s happening?.
Thanks.

PD. 128 of RAM (PC100 8ns).
G400 32 DH.

does the same thing occur when you are not O/C? Have you tried changing your agp aperture size in your BIOS?

3dmark runs perfectly at 500 and at 515. No
trouble at all.
I used to have problems with the G400. Now
it works properly at AGPx1.

thanks.
