2.6.3 PCI slots
This motherboard implements the PCI-X (Peripheral Component Interconnect
Extended) bus technology to support up to 100MHz data transfers, or about
800MB/s. This bus technology is primarily designed for servers to increase
the performance of high bandwidth devices such as Gigabit Ethernet cards
and Ultra3 SCSI interfaces. PCI-X is backward compatible with the earlier PCI
bus technology making it possible to install PCI and PCI-X cards at the same
time, but the bus speed will be that of the slowest card. The following figure
shows the five PCI-X slots and one PCI slot on the motherboard.

PCI-X slots (PCI X1 to X4)
The motherboard may come with either the LSI ® 53C1010R or the LSI ®
53C1030 SCSI controller. Depending on the onboard SCSI controller, the
following table shows the varying bus speeds for the PCI-X slots according to
the PCI-X specification 1.0a.
* PCI-X3 supports the AMI Express 600 ZCR (Zero Channel RAID) card
PCI slot (PCI6)
PCI6 is a 32-bit/33MHz 5V PCI slot with a Low Pin Count (LPC) signal
connector to accommodate the ASUS Server Management Card. This slot
has the same specifications regardless of the onboard SCSI controller.
