16 GB Registered ECC DDR4 Server Memory

This 16 GB DDR4-2666 registered ECC module is built for servers that require error-correcting, buffered memory. It suits administrators upgrading or repairing HPE systems where the original part number 840756-C91 is specified. The 2Rx8 organisation and 1.2 V operation match the factory configuration.

Straightforward 288-pin DIMM installation

The module installs like any standard 288-pin DDR4 DIMM; seat it firmly until the latches click. Because it is registered ECC, the platform must support buffered memory or the system will not post. Mixing registered with unbuffered DIMMs is the most common cause of boot failure.

Verify registered ECC support

Confirm the server’s memory controller accepts registered ECC DDR4 before ordering. Check the service manual for maximum per-slot capacity and required population order, as some platforms demand identical ranks per channel. The module carries a lifetime warranty from the supplier.

Questions about this item

How can I confirm the module is running at DDR4 2666 (PC4 21300) after installation?

Check the BIOS or system management tool; it should report 2666 MT/s, 1.20 V, registered ECC, 2Rx8 organisation and 16 GB capacity for each installed module.

What is included in the box and what must be sourced separately?

The box contains the 16 GB 288-pin DDR4 RDIMM only; no extra cables, brackets or software are required — just an available registered DIMM slot on a compatible HPE server.

Should I choose the 16 GB 2Rx8 version or a different capacity for my HPE server?

Select the 16 GB 2Rx8 module (equivalent to HPE 840756-C91) when your configuration calls for that exact rank and density; other capacities or ranks will have different part numbers and are not covered by this listing.
