2.6.3 PCI slots
This motherboard implements the PCI-X (Peripheral Component Interconnect
Extended) bus technology to support up to 133MHz data transfers, or about
1.06GB/s. This bus technology is primarily designed for servers to increase
the performance of high bandwidth devices such as Gigabit Ethernet cards
and Ultra320 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 X5)
The motherboard comes with the LSI ® 53C1030 SCSI controller. The
following table shows the varying bus speeds for the PCI-X slots according to
the PCI-X specification 1.0a.
* Plugging in a card into one of the slots allow for 133MHz bus speed. Plugging in two
cards reduces the bus speeds to 100MHz for both cards. Plugging in three cards
allows for 66MHz for all three cards.
** PCI-X5 supports the LSI MegaRAID 320-0 or Intel SRC 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.
