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 ECC PC2100/1600 DDR DIMMs, and two high speed IMBs plus one thin IMB to connect to the south bridge CSB5.

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

604-pin CPU sockets. A 604-pin surface mount, Zero Insertion Force (ZIF) socket for the Intel® Xeon™ processor with 512KB L2 cache and a 400 MHz system bus that allows up to 3.2GB/s data transfer rate.

8-pin 12V SSI power connector. This power connector is for an ATX power supply.

IDE connectors. These dual-channel bus master IDE connectors support up to four Ultra DMA/100/66, PIO Modes 3 & 4 IDE devices. Both the primary (blue) and secondary (black) connectors are slotted to prevent incorrect insertion of the IDE ribbon cable.
