Standard Memory Replaced with Optional Memory

Up to 4096 MB memory is available with the optional installation of PC3200 Unbuffered ECC DDR SDRAM DIMM Memory kits.

These systems support PC3200 DDR memory and come standard with a single PC3200

DIMM installed.

The system board provides four DIMM sockets:

Socket 1 (blue connector), channel A

Socket 2 (black connector), channel A

Socket 3 (blue connector), channel B

Socket 4 (black connector), channel B

DIMMs do not need to be installed in pairs although installation of pairs (an equal DIMM for each channel) provides the best performance. The BIOS will detect the DIMM population and set the system accordingly as follows:

Single-channel mode - DIMMs installed for one channel only

Dual-channel asymmetric mode - DIMMs installed for both channels but of unequal channel capacities. Dual-channel interleaved mode (recommended) - DIMMs installed for both channels and offering equal channel capacities, proving the highest performance.

These systems require DIMMs with the following parameters:

Unbuffered

256 MB, 512 MB, and 1 GB memory technology PC3200

ECC DIMMs only

The first DIMM should be installed in Socket 1. A DIMM should not be installed in Socket 2 without a DIMM in Socket. Likewise a DIMM should not be installed in Socket 4 without a DIMM in Socket 3. A DIMM need not be installed in Socket 2 in order to install a DIMM in Socket 3.

The table below shows some of the suggested memory configurations for these systems.

NOTE: Table below does not list all possible configurations. Balanced-capacity, dual-channel loading yields best performance.
