SKU CH-54CE-GQ60G

ECC registered DDR3 DIMM running at 1600 MHz for HP G8 servers

  • ECC registered single-rank reliability
  • HP part 647648-571 guaranteed compatibility

HP 647648-571 4GB DDR3 Memory Module

This HP 647648-571 module provides 4GB of DDR3 ECC registered memory for compatible G8 servers. It operates at 1600MHz with a CL11 latency and uses a single-rank design. The DIMM is sold new and ready for installation in supported systems. Builders needing non-ECC or unbuffered memory should look elsewhere.

Replaces Lower-Capacity or Slower DDR3 DIMMs

Upgrading from smaller DDR3 modules or slower speeds increases available memory bandwidth for virtualisation and database workloads. The jump is worthwhile when the server board supports 1600MHz registered ECC and the application benefits from the extra capacity. Systems requiring higher densities or different form factors cannot use this module.

Questions about this item

What DIMM slot spacing does the HP 647648-571 DDR3 module require?

The module is a standard DDR3 DIMM, so it fits any server board with DDR3 slots; the 1×4 GB single-rank layout occupies one slot.

Which BIOS setting is often missed when installing this ECC registered DDR3 memory?

Enable ECC support in the BIOS after seating the module; without it the registered DIMM will post but error correction stays inactive.
