Dan, Re: "This limits the PCI transfer rates to 90MB/s when it should be 133MB/s"

Any arbitrated bus like PCI is already limited by overhead, so it will never reach 133MB/s, even in a perfect implementation, on a good day, with a great device, and with efficient software drivers. Burst data rates simply don't happen for any long length of time, and subsequent arbitration eats up clock cycles. I would expect the max data transfer of any PCI system to be in the range of 90-100MB/s.

Dan, I'd much rather have an errata that limits practical PCI bandwidth from 100 MB/sec to 90 MB/sec than a bug that crashes the system.

But hey, I'm sure the "overclocker's choice" would rather choose performance over stability. Hope you don't follow that philosophy when buying computers for your workplace. ;-)
