All DIMMs installed must be the same speed (DDR2 PC4200). 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 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.
