Server DDR2 Module

The HPE 1GB DDR2-400 ECC Registered 240-Pin Server RAM is a memory module built for enterprise server platforms. It uses DDR2 SDRAM technology and operates at 400 MHz with a CL3 latency timing. The module includes error-correcting code and registered buffering for data integrity.

For legacy server maintenance

This module suits administrators maintaining or upgrading compatible HPE server systems that require DDR2 registered ECC memory. It is not for builders assembling new workstations, gamers seeking high-speed RAM, or laptops and desktops that use unbuffered non-ECC modules.

DDR2-400 registered ECC spec

The decisive specification is the DDR2-400 PC2-3200 registered ECC standard on a 240-pin form factor. Only systems explicitly designed for this memory type and speed will accept the module. Verify the server manual before purchase.

Questions about this item

Does my server motherboard need 240-pin DDR2 slots to use this module?

Yes, the module is a 240-pin DDR2-400 registered DIMM, so the board must provide DDR2 slots that accept registered memory.

Can I add this 1 GB DDR2-400 stick alongside slower DDR2 modules I already have?

The system will run all modules at the speed of the slowest installed stick, so this CL3 PC2-3200 module will down-clock to match older DDR2 memory.

How can I confirm the module is recognised as 1 GB ECC registered at 400 MHz after installation?

Check the BIOS memory summary or run a tool such as dmidecode; it should report 1 GB, DDR2-400, ECC registered, part number 359242.
