    Whats teh OS and is the card sharing and IRQ with another card at the board level? YOu get only 4 irq's for all pci/agp/usb etc... devices at the MB level.

    Er, looks like it's the IRQs:

    How would I fix this? Manually assign IRQs?

    Your running a acpi HAl and it attempts to jam then together even more but at the MB level all your cards and acpi and USB only get 4 IRQ's Some vards don't "play" as well sharing at that level and sometimes simply moviong cards around helps.

    For instance on my KR7 pci slot 5 shares with the hpt raid so you always leave 5 empty

    I got it isolated to its own IRQ's (with the exception of the USB stuff) and I'm getting similiar result that are slightly better (4-5mb higher on write on the high end of the test)...
