Module identity and target use

The HPE 726719-S21 is a 16GB DDR4 registered memory module rated at 2133 MHz. It is built for server platforms that require registered signal processing and CL15 latency.

Compatibility checks before ordering

Verify that your server accepts DDR4-2133 registered DIMMs and has a free slot for a single 16GB module. Confirm the platform supports the PC4-17000 standard and the physical dimensions of 3.5" by 7.8".

Who this suits and who should look elsewhere

This module suits administrators upgrading or repairing HPE servers that specify registered DDR4 memory. Buyers who need unbuffered memory, a different speed grade, or a larger capacity per slot should look elsewhere.

Questions about this item

What comes in the box with the HPE 726719-S21 16GB DDR4 2133 MHz module and do I need anything else?

The package contains one 16GB DDR4 registered DIMM. No extra parts are required for installation in a compatible server slot.

How do I decide between the listed versions or capacities for this HPE 726719-S21 module?

This part number identifies a single 16GB DDR4-2133/PC4-17000 registered module. Choose it when your server requires exactly 16GB per slot at 2133 MHz.

What does the 2133 MHz rating mean once the module is installed in a real server?

The memory will run at up to 2133 MHz with CL15 latency, delivering PC4-17000 bandwidth when the server memory controller supports that speed.
