DIMM installation guidelines
Observe the following guidelines when installing additional memory:
• DIMMs installed in the server must be Unbuffered DDR DRAM, 2.5 V, 64
bits wide, and ECC.
• All DIMMs installed must be the same speed (DDR PC3200). Do not install
DIMMs supporting different speeds.
• If only a single DIMM is installed, HP recommends installing it in slot 1A.
BIOS detects the DIMM population and sets the system as follows:
• Single-bank mode: DIMMs installed in one bank only.
• Dual-bank asymmetric mode: DIMMs installed in both banks, but of unequal
capacities per bank.
• Dual-bank interleaved mode: DIMMs installed in both banks with equal bank
capacities.
The following table lists some, but not all, possible configurations. For best
performance, HP recommends dual-bank interleaved mode configurations.
