HPE 16GB DDR4 2933 Registered ECC DIMM

This module is a 16GB DDR4 2933 registered ECC DIMM built for HPE server platforms that require PC4-23400 memory. It operates at 1.20V with a CAS latency of 21 and a 1Rx4 organisation. The part is supplied new and carries the manufacturer part number P00920-B21.

Who this suits and who it does not

It suits administrators upgrading or repairing compatible HPE systems that specifically call for registered ECC DDR4 2933 modules. It is not for desktop or workstation boards that accept only unbuffered non-ECC memory. Buyers who need a different capacity, a different speed grade, or unregistered DIMMs should look at other parts.

Deciding specification: registered ECC DDR4 2933

The single specification that determines fit is the registered ECC DDR4 2933 interface with CL21 timing. Only systems qualified for this exact registered ECC DDR4 2933 configuration will accept the module. Verify the platform memory list before purchase.

Questions about this item

Should I choose the 16GB 1Rx4 module or a different capacity for my server?

This kit provides a single 16GB 1Rx4 registered DIMM; select it when your HPE server requires that exact rank and capacity per slot.

What does the DDR4 2933 speed mean once installed in a compatible HPE system?

The module runs at 2933 MT/s with CL21 21-21-21 timing at 1.20V, delivering PC4-23400 bandwidth when the platform supports that data rate.

How does the PC4-23400 rating and registered ECC design affect real-world use?

PC4-23400 denotes the peak transfer rate; the registered ECC architecture adds a clock cycle for signal integrity, enabling stable operation in multi-DIMM server configurations.
