HPE-compatible 32 GB DDR4 server module

This 32 GB DDR4 registered ECC module is built for HPE servers that require PC4-25600 speed and 2Rx4 organisation. It targets IT teams expanding memory in existing HPE platforms without purchasing OEM-labelled sticks. The module runs at 1.20 V and fits standard 288-pin DDR4 slots.

Major-brand chips and registered design

Each stick uses Samsung, SK Hynix or Micron components and carries a lifetime warranty from Brute Networks. Registered buffering reduces electrical load on the memory controller, helping stability in multi-DIMM configurations. Identical modules are shipped together so capacity scales cleanly across channels.

Upgrades for HPE part P07646-H21

The module directly replaces HPE part number P07646-H21 at a lower cost while preserving the original factory warranty. It suits administrators who need to maximise density in supported HPE systems. Buyers whose servers demand a different rank layout or voltage should verify compatibility before ordering.

Questions about this item

What speed and standard does the PC4-25600 DDR4-3200 module run at?

The module is rated for DDR4-3200 (PC4-25600) and operates at 1.20 V as a registered ECC DIMM.

What physical slot and keying does the 288-pin DDR4 SDRAM require?

It fits a standard 288-pin DDR4 DIMM slot with the DDR4 key notch; the registered design adds a register chip between the DRAM and the memory controller.

How is the registered ECC DIMM installed, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the server recognises the full 32 GB at 3200 MT/s with ECC active.
