MS-9618 ATX Server Board
Slots
The mainboard provides:
†
Three 32-bit/33MHz v2.3 PCI slots (support 3.3V/5V PCI bus interface)
†
One PCI Express x8 slot ( this PCIE_2 slot will accept x8 cards, but run
at x4 speeds / PCI Express Bus specification v1.0a compliant)
†
One PCI Express x8 slot ( this PCIE_1 slot will accept x8 cards and run at
x8 speeds / PCI Express Bus specification v1.0a compliant)
PCI (Peripheral Component Interconnect) Express Slots
The PCI Express slots support high-bandwidth, low pin count, and serial interconnect
technology. PCI Express connectors are similar in appearance and connection method
to 32-bit PCI slots. PCI Express 1X slots are about the size of current modem riser
slots (about 1" long), while the X16 interface (164 pins) for graphics is very similar in
appearance to the standard AGP port. The flexibility to adapt to PCI express devices
of different bandwidths is built into the midrange X4 and X8 slots that we have seen.
PCI Express architecture provides a high performance I/O infrastructure for Desktop
Platforms with transfer rates starting at 2.5 Giga transfers per second over a PCI
Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general pur-
pose I/O. Also, desktop platforms with PCI Express Architecture will be designed to
deliver highest performance in video, graphics, multimedia and other sophisticated
applications. Moreover, PCI Express architecture provides a high performance graphics
infrastructure for Desktop Platforms doubling the capability of existing AGP 8x de-
signs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers, while PCI Express x1 supports transfer rate of 250 MB/s.
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs. W hen
adding or removing expansion cards, make sure that you unplug the power supply
first. Meanwhile, read the documentation for the expansion card to make any neces-
sary hardware or sof tware settings for the expansion card, such as jumpers,
switches or BIOS configuration.
