32GB DDR3 1066MHz ECC Registered DIMM

This 32GB DDR3 module runs at 1066MHz (PC3-8500) with CL7 latency and 1.50V operation. It is an ECC registered DIMM built in a 4Rx4 configuration using major-brand chips on a 240-pin form factor. The module is a compatible replacement for HP part numbers 627814-B21, 628975-081 and 632205-001.

Server administrators expanding memory

This module suits IT teams upgrading or repairing compatible HP servers and workstations that accept DDR3 1066MHz ECC registered DIMMs. It is not for desktop PCs or consumer laptops that require unbuffered non-ECC memory. Buyers whose systems need a different DDR3 speed, a different rank layout, or a different voltage should verify the platform specification before ordering.

4Rx4 rank organisation determines slot population

The 4Rx4 rank structure counts as four logical ranks per module, which affects how many DIMMs the memory controller can address per channel. Check the server documentation for maximum supported ranks per channel and total system capacity to ensure this 32GB module fits the allowed configuration.

Questions about this item

Does my server need a 240-pin DDR3 DIMM slot to accept this 32GB registered module?

Yes, this is a 240-pin DDR3 DIMM running at 1066 MHz (PC3-8500) with 1.5 V registered ECC; your motherboard must provide a matching DDR3 RDIMM slot.

Can I mix this 4Rx4 32GB stick with existing 1Rx4 or 2Rx4 DDR3-1066 modules in the same channel?

Mixing ranks is possible if the platform supports 4Rx4 modules, but the memory controller will run all modules at the lowest common speed and voltage; check the system manual for maximum rank-per-channel limits.

How can I confirm the module is detected at 32 GB with ECC active after installation?

Enter the BIOS or run a hardware-inventory tool such as dmidecode; it should report a single 32 GB DDR3-1066 registered ECC DIMM at 1.5 V with the correct part number.
