Axiom 4GB DDR2 667 Registered ECC

This Axiom 483401-B21-AX kit provides 4GB across two 2GB DDR2 667 modules. It is built for HP ProLiant DL165 G5 and DL185 G5 servers that require registered ECC memory. The PC2 5300 rating matches the platform specification.

240-Pin DDR2 installation notes

The 240-pin DDR2 DIMMs seat in the standard server slots for these ProLiant models. Registered modules must be paired correctly for the memory controller to initialise. Mixing unbuffered or non-ECC sticks will prevent the system from posting.

4GB capacity and headroom

The 4GB total suits legacy workloads and basic virtualisation on the named G5 platforms. Larger datasets or heavier consolidation will exceed this limit quickly. Servers needing more memory must use higher-density registered DDR2 modules approved for the same models.

Questions about this item

How can I verify the 240-pin DDR2 667 modules are running at PC2 5300 speed after installation?

Enter the server BIOS or use a tool like CPU-Z to confirm the memory operates at 667 MT/s with ECC registered timings.

The kit contains two 2 GB 240-pin DDR2 667 ECC registered DIMMs; no additional components are required for the listed ProLiant models.

Which capacity version should I choose if my HP ProLiant DL165 G5 needs 4 GB of DDR2 667 ECC registered memory?

Select the 4 GB kit (2 × 2 GB) as it matches the required capacity and speed for the DL165 G5 and DL185 G5.
