Installing Dimms - HP ProLiant DL320s User Manual

Installing DIMMs

Observe the following guidelines when installing additional memory:
•
DIMMs installed in the server must be unbuffered DDR2 SDRAM, 2.5 V, 64 bits wide, and ECC.
•
All DIMMs installed must be the same speed (DDR2 PC5300). 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.
