Upgrading the system memory
This section explains the procedures for removing and installing a
memory module.
Memory configuration guideline
The AT110 has four DIMM slots. The DIMM slots support dual-channel
DDR2 unbuffered ECC memory modules.
•
Channel A - DIMM A1 and DIMM A2
•
Channel B - DIMM B1 and DIMM B2
For the system to function, DIMM modules must be installed following
the slot sequence listed below.
•
To ensure data integrity, use only approved 240-pin, DDR2
unbufferred DIMM ECC modules in 1 GB or 2 GB capacities.
•
Use identical modules — same specification for size, speed, and
organization.
•
The minimum memory configuration is one DIMM, installed in
DIMM A1 slot.
•
DIMMs on channel A (DIMM A1 and A2) are paired with DIMMs on
channel B (DIMM B1 and B2) to enable two-way interleaving.
When only two DIMMs are being used, the population order must
be DIMM A1 and DIMM B1 to ensure dual-channel operating
mode.
•
For best performance and dual-channel interleave operation,
DIMM modules must be installed or removed in matched pairs,
following the slot sequence: DIMM A1 and B1 first, then DIMM A2
