Need help with MS-6330 V3.0 & XP1600

[llew]

I have a MS-6330 V3.0 Turbo Raid motherboard with Bios 3.2, recently I upgraded the CPU to a XP1600, the system runs fine at 100MHz Fsb. But whenever I set the fsb to 133mhz (via jumper setting on the motherboard), my PCI cards goes crazy, modem will disconnect immediately after I established connection, Hollywood decoder card would output very wavy pictures... I think it have something to do with the PCI divider settings, but there's no way to modify it under the bios settings.

Funny... the board should automatically use the 1/4 divider... my board didn't go
crazy when I removed the jumper (I had it at factory default settings at the time).
