Pci 2.1 Lantency Compliant?

If everything seems to be running ok, you should probably leave it alone. However, you may find that some newer pci bus master devices require this facility, in which case you may need to enable it.

In PCI 2.1 specification, the initial part of a data transfer has to be completed within 16 or 32 pci clock cycles, otherwise a RETRY command must be issued. This was not the case with the PCI 2.0 specification. A device built to PCI 2.1 specification will still work if it can complete all it's transactions within 16 or 32 clock cycles, but this cannot be guaranteed. Note - this only applies to bus master devices.

I bet that's made it clear as mud.

Hey thanks,I always wonderd what it did.
I got a Asus MB,but the book I got with it doesn't explain a whole lot about the chipset features-infact it doesn't really tell you much of anything but the basics.

You just described most of the motherboard manuals.
