Installing Hardware Options 4-47 Memory Server node memory can be expanded by installing Compaq Dual Inline Memory Modules (DIMMs). The Compaq ProLiant CL380 system supports up to four registered Synchronous DRAM (SDRAM) DIMMs installed in slots on the system board. Memory can be added one module at a time. IMPORTANT: Compaq recommends that both server nodes be configured identically. You must observe the following guidelines when installing additional memory: DIMMs installed in the ProLiant CL380 must be 133-MHz registered SDRAM, 3.3 volts, 72-bits wide, and ECC. All DIMMs installed must be of the same speed, for example, all 133 MHz. The system is shipped with one DIMM in DIMM slot 1 of each server node. DIMMs should be installed in sequential order starting at DIMM slot 1. CAUTION: Use only Compaq DIMMs. DIMMs from other sources may adversely affect data integrity.
