There is space for a second processor, but the base configuration has a terminator installed in the second processor's socket. • There is space for two Voltage Regulator Modules (VRM), one for each installed processor. The base configuration has a single VRM for the single processor. • The processor system switches synchronize the processor to the system bus. Refer to the switch settings key printed on the System Board in the upper right corner. • The Bus Speed Jumpers set 100 MHz or 66 MHz bus speed. • The DIMM sockets hold up to four 5V DIMM modules.
