Intel® 82551QM Fast Ethernet controller. This LAN controller fully supports 10BASE-T/100BASE-TX networking protocols.

Intel® 82544GC Gigabit Ethernet controller. This controller is an integrated Ethernet LAN component that supports 1000Mbps, 100Mbps, and 10Mbps data rates. The 82544GC is optimized for LAN on Motherboard designs (LOM), enterprise networking, and Internet appliances that use PCI or PCI-X bus. The controller provides a 32/64-bit, 33/66MHz interface to the PCI bus that supports PCI Specification Rev. 2.2, and to the PCI-X extension to the PCI Local Bus Rev 1.0a at clock rates of up to 133MHz.

DDR DIMM sockets. These six 184-pin DIMM sockets support up to 12GB system memory using registered ECC PC2100/1600 DDR DIMMs.

ServerWorks® 64-bit I/O Bridge (CIOB-X2). The Champion I/O Bridge (CIOB-X2) provides a high performance data flow path between the IMB and the I/O subsystem, which supports multiple PCI/PCI-X interfaces that allows large, efficient, and flexible I/O configurations. The CIOB-X2 supports 64-bitPCI/PCI-X I/O buses that comply with PCI 2.2 specification.

ServerWorks® Grand Champion LE north bridge (CMIC-LE). The Champion Memory and I/O Controller LE (CMIC-LE) acts as the host bridge of the Grand Champion Low End (GCLE) SystemSet. The CMIC-LE device interfaces directly to the processor bus, and integrates the functions of the main memory controller and the Inter Module Bus (IMB) interface unit. The processor interface supports a 400MHz Front Side Bus (FSB) providing a 3.2GB/s bandwidth, 2-way interleaved 3.2GB/s memory bandwidth with up to 12GB registered PC2100/1600 DDR DIMMs, and two high speed IMBs plus one thin IMB to connect to the south bridge CSB5.

5-switch DIP (SW1). This 5-switch Dual Inline Package (DIP) allows you to set the CPU external frequency.

24-pin ATX power connector. This power connector is for an ATX power supply.

604-pin CPU sockets. Two 604-pin surface mount, Zero Insertion Force (ZIF) sockets for the Intel® Xeon™ processors with a 400 MHz system bus that allows up to 3.2GB/s data transfer rate.
