HPE 647651-181 8GB DDR3 1600MHz ECC Registered DIMM

SKU CH-F465-1X9NQ MPN 647651-181

An 8 GB DDR3 server memory module with ECC and registered signal processing for compatible HP ProLiant systems

  • Electrical Outlet Plug TypeRAM Module
  • 8 GB DDR3 capacity supports server workloads
  • ECC registered design protects data integrity
  • 1600 MHz DDR3-1600 speed matches system specs
  • 240-pin DIMM fits ProLiant BL465c Gen8 and DL385p Gen8
  • RoHS certified for environmental compliance

Server Memory Module

This 8 GB DDR3 DIMM is built for HPE ProLiant servers including the BL465c Gen8 and DL385p Gen8. It delivers ECC registered operation at 1600 MHz for workloads that require error correction and signal integrity.

Installation Notes

The 240-pin DIMM fits standard DDR3 server slots and is keyed to prevent misalignment. Installers must verify the server model matches the supported list; other ProLiant generations or non-HPE platforms will not recognise the module.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors continuously during long compute cycles without halting the system. Registered signalling reduces electrical load on the memory controller, helping stability when all slots are populated for extended periods.

Questions about this item

How can I verify the 1600 MHz DDR3 module is recognised at the correct speed after installation?

Check the server BIOS or iLO interface; it should report 8 GB at 1600 MHz with ECC and registered operation for part 647651-181.

What comes with the 647651-181 DIMM and what must be sourced separately?

The package contains the single 240-pin DIMM only; any additional memory modules, risers or server rails are not included.

Which HPE ProLiant models are confirmed compatible with this 8 GB DDR3-1600 ECC registered DIMM?

The module is qualified for the BL465c Gen8 and DL385p Gen8 servers listed in the manufacturer compatibility data.
