Server memory for HPE systems

This 32GB DDR4-2666 module is built for HPE servers that require registered ECC memory. It runs at 1.20V with a 2Rx4 organisation and fits standard 288-pin DIMM slots. The part matches HPE part number 838083-H21 and uses major-brand chips from Samsung, SK Hynix or Micron.

Installation and common issues

Installation follows the usual DIMM procedure: power down, open the chassis, align the notch and press until the clips lock. Because the module is registered, the server must support registered memory; unbuffered-only platforms will not post. Mixing ranks or speeds can prevent the system from booting, so populate identical modules in matched channels.

Suitable buyers and mismatched needs

This suits administrators upgrading or repairing HPE platforms that specify PC4-21300 registered ECC DIMMs. Buyers who need unbuffered memory for a workstation or consumer board should look elsewhere, as the registered buffer makes this module incompatible with those systems. Anyone requiring a different capacity, speed or voltage must select a module that matches their platform specification.

Questions about this item

How do I confirm the 288-pin DDR4 module is running at 2666 MHz after installation?

Check the BIOS or a tool like CPU-Z; the memory should report DDR4-2666 (PC4-21300) speed, 1.20 V voltage, registered ECC and 2Rx4 organisation.

What comes in the box and is anything else required?

The package contains the 32 GB DDR4-2666 registered ECC DIMM; no extra parts are needed if your server has a free 288-pin DDR4 slot.

When should I choose this 32 GB 2Rx4 version instead of another capacity?

Select this module when you need a single 32 GB stick with 2Rx4 density that matches HPE part 838083-H21 for compatible servers.
