You don't mention the make/model of the SCSI controller. I'm guessing that
it's obscured by the fact that it's an onboard.

Verify your termination: that the card is configured to be a terminator
at its end, and the drives _aren't_.
Borked termination can cause all manner of unpredictable SCSI failures.

On a whim: use the bios to set the SCSI controller to use SCSI-160 speed
instead and see if it works then. It's possible that 320 isn't supported
on that card yet. This is a "wild guess"/"gut feeling" thing, though, so
don't get upset if it's not the cause.

Sounds more like SCSI than CPU.

It's also possible that your motherboard is faulty. Did it come with any
diagnostic utilities or anything?
Bad hardware has a bad habit of sneaking in and making life difficult, and
it can be very difficult to detect!
