CPU Fan Connectors
The CPU fan connectors provide power for the fans mounted on the
processor heatsinks. These fans cool the processors and prevent
overheating. Note that not all processor heatsink have or need fans. If the
processor heatsink includes a fan, connect it to the correct fan connector.
Voltage Regulator Modules
Each CPU must have a dedicated voltage regulator module (VRM) which
adjusts the voltage supplied to the CPU. The VRM for the first CPU (CPU
1) is embedded on the system board.
Memory
The system comes standard with 64-MB of Error Checking and Correcting
(ECC) RAM. System RAM is expandable up to 1-GB using ECC 60-ns 72-
bit synchronous DRAM (SDRAM) DIMMs (4 DIMM sockets).
