It's hard to tell without knowing your hardware configuration.
It is a PC Chips M571 v3.2A. As noted in the original post, there is a jumper for PCI bus speed ratio, which can be set to 2/5 for 75Mhz (PCI bus at 30Mhz) and 83Mhz (33Mhz) so I'm definitely not overclocking the PCI bus.
I did notice tonight that one of the jumpers used for clock speed doesn't seem to fit very snugly so I might find another jumper and try again... maybe that was the issue when trying 75Mhz bus speed.
