Oh, forgot about the NCR 810 SCSI card.

The board/chipset doesn't support PCI dividers, so other PCI harddisk controllers most likely would have problems as well.
If you want to run 40MHz on the PVI-486SP3, I'm afraid you'll have to use the crappy onboard CMD640 or insert a VLB/ISA based controller.

I'll stick at 33mhz FSB 😀 I won't be able to run any SVGA games at decent speed any way with 40mhz FSB
It would feel like going back to jurassic times if I went back to IDE again 😁

This is why I favour the VL/EISA boards. I can run the VL bus at any crazy speed I like but still run high performance disk controllers in spec.

Agree but still haven't found an Eisa mobo which has jumpers for FSB settings...

I don't think the SST linear verify speed test actually transfers data over the bus. Even my Seagate 13GB IDE drive manages more than "20 MB/s" on the same board.
A SiS 496/497 board manages about 15 MB/s over the PCI bus (with a following wind 🤣). Actually it's more like 10 MB/s, because Amigaz' fast SCSI drive gets about the same results in the read speed tests as my crappy IDE drive.
