Upgrading the system memory

This section includes instructions for removing and installing a memory module.

Altos G530 has four DDR2-400 DIMM slots. Each slot supports 512 MB, 1GB or 2GB memory modules. The maximum memory capacity is 8GB.

Memory module installation guidelines

•The minimum memory configuration is one DIMM, installed in the DIMM 1B socket (the socket farthest from the CPU sockets). However, for optimum performance and dual-channel interleave operation, a minimum of two DIMMs should be installed. DIMMs on channel A (DIMM 1A and 2A) are paired with DIMMs on channel B (DIMM 1B and 2B) to enable 2-way interleaving.

Note: Dual-channel memory requires symmetrical memory modules using the same density (e.g. 512 MB), bus width (e.g. x8, x16) and granule technology (e.g. 512M-bit).

•Populate both DIMMs in bank 1 (DIMM 1B and 1A) first, before populating DIMMs in bank 2 (DIMM 2B and 2A). Bank 2 must be populated in pairs.

Note: Refer to the “Mainboard layout” on page 14 for the location of the DIMM slots.
