HPE-compatible 16GB DDR4-2666 registered ECC module

This 16GB DDR4-2666 registered ECC module is built for servers and workstations that require error-correcting memory. It matches HPE part number 838089?H21 and is validated for 100 per cent compatibility with supported platforms. System administrators upgrading or repairing qualified HPE infrastructure will find it a direct fit.

288-pin DDR4 SDRAM with major-brand chips

The module uses a standard 288-pin DDR4 SDRAM form factor and operates at 1.20V. Chips come from Samsung, SK Hynix or Micron, the same manufacturers used for OEM branded modules. Registered buffering and a 2Rx8 organisation help maintain signal integrity in multi-DIMM configurations day to day.

Speed and rank decide fit for your server

The module runs at DDR4 2666 (PC4-21300) with a 2Rx8 rank structure. This speed and rank combination is the single specification that determines whether the part will work in a given memory slot population. Buyers needing a different data rate, rank layout or non-ECC memory should select another module.

Questions about this item

What speed does the DDR4-2666 (PC4-21300) interface cap at in practice?

The module runs at 2666 MHz with a PC4-21300 bandwidth rating, delivering 16 GB of registered ECC memory at 1.20 V.

What physical slot and form factor does this 288-pin DDR4 DIMM need to fit?

It requires a standard 288-pin DDR4 DIMM slot in a server motherboard that supports registered ECC memory.

How is the module installed and which step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the server BIOS recognises the full 16 GB at 2666 MHz.
