DDR SYNCH DRAM DIMM N ON -ECC M EMORY
The HP business desktop d325 PC has two memory DIMM slots and supports dual channel memory configurations. It is not necessary to add memory in
pairs or kits, but for best performance, memory should be added in pairs and should be the same type. For example, 2x128-MB memory modules will
perform better on some applications than 1x256-MB memory module because of the dual channel memory support on the d325.

Configurations can be selected with either a 128-MB, 256-MB, 512-MB, 1024-MB, or 2048-MB memory. Memory types supported include PC2100
(DDR266) and PC2700 (DDR333).
Various combinations of single-DIMM (for future upgradeability) and double-DIMM (for enhanced dual-channel memory performance) will be offered.
Other “mis-matched” memory combinations, such as 384MB (using 1x128-MB and 1x256-MB) will not be offered due to performance limitations of the d325.
In these mis-matched configurations, the maximum operation speed is determined by slowest DIMM. After installing a mis-matched configuration, the
following message will appear on the screen: “217 Memory DIMM Configuration Warning: Installed memory DIMM configuration is unbalanced. Multiple
DIMMs installed of unequal size. For best performance, use a balanced DIMM configuration.”

NOTE: It is not necessary to add memory in pairs or kits. Memory upgrades are accomplished by adding single or multiple DIMMs of the same or
varied sizes. This chart does not represent all possible memory configurations.
