Perfomance drop

[Yop]

Hello everybody,
I got a PIII-450 o/c 600 and a MAX. I've done a fresh install of Windows 98 and install last bios and PD 5.21 on my system.

Tested it on 3DMark99:
800*600*16 ~ 5950 marks (GREAT)
1280*1024*32 ~ 2600 marks (BOOOOOH)

I know I should get something like 3300 on this kind of system! (seen on http://www.murc.ws/reviews/Millenniu...Review03.html)

I have a P3B-F with sblive! and 2940 SCSI-2 card.


Thanks in advance,
Yop
