Fully Buffered DDR2 for ProLiant servers

This kit delivers 8 GB of DDR2-667 ECC memory in four 2 GB modules built to the PC2-5300 standard. Each 240-pin DIMM uses fully buffered architecture with 2Rx4 organisation and CL5 timing at 1.8 V. It is designed for HP/Compaq ProLiant servers and select workstations that require registered ECC modules.

Suits maintainers of listed G3–G5 ProLiant

Administrators upgrading DL360 G5, DL380 G5, ML350 G5 or ML370 G5 systems can use this kit to populate vacant slots. It is not for desktop PCs, laptops or any platform that accepts only unbuffered non-ECC DDR2. Buyers needing higher densities or faster speeds must verify their system supports larger fully buffered modules.

Check your server memory configurator before

Confirm the target machine accepts 240-pin fully buffered DDR2-667 ECC DIMMs and note the maximum supported capacity per slot. Verify the number of available slots and the required population order in the service manual. Ensure the BIOS revision in use recognises 2 GB 2Rx4 modules.

Questions about this item

Does this 4×2 GB DDR2-667 fully buffered kit require a server motherboard that supports FB-DIMM technology?

Yes, the modules are fully buffered DDR2 DIMMs and must be installed in a system designed for FB-DIMM memory such as the listed HP/Compaq ProLiant and workstation models.

Will the 2Rx4 rank organisation of these sticks work in a ProLiant ML150 G3 that currently uses 1Rx4 modules?

The kit is validated for the ML150 G3; the server's memory controller accepts the 2Rx4 configuration used by these 2 GB modules.

After installation, how can I confirm the kit is running at DDR2-667 with ECC active?

Check the BIOS memory information or the OS memory report — both should show 667 MHz speed and ECC enabled for the 8 GB total capacity.
