HP 32GB DDR3 Registered DIMM

This 32GB module uses 240-pin DDR3 SDRAM running at 1066 MHz with PC3-8500 rating and CAS latency CL7. It is ECC registered and organised as a quad-rank 4Rx4 part. The component carries HP part number 627814-B21 and is supplied new for server memory upgrades.

Suited for HP ProLiant Gen8 servers that require

The registered design with ECC and quad-rank layout matches the needs of virtualised workloads and large database applications on qualified platforms. Systems that accept only unbuffered memory or that cannot address a 32GB quad-rank DIMM will not be compatible with this module.

Quad-rank 4Rx4 registered architecture

The single most decisive specification is the 4Rx4 quad-rank registered organisation, which determines whether the server memory controller can populate this 32GB DIMM within its supported rank-per-channel limits.

Questions about this item

What does the 32 GB capacity mean for a server running virtual machines?

The module provides a single 32 GB stick of DDR3 memory, letting you add large capacity in one slot for virtualisation workloads.

How does the PC3-8500 rating limit real-world throughput?

PC3-8500 caps the module at 1066 MT/s, so peak bandwidth is limited to the DDR3-1066 specification.

Will the 240-pin registered DIMM fit a standard ProLiant Gen8 memory slot?

Yes, the 240-pin DDR3 registered form factor matches the DIMM slots used in HP ProLiant Gen8 servers.
