Purpose-built server memory

HPE P00924-B21 is a 32GB Registered DDR4 2933 module designed for compatible HPE servers that require registered ECC memory. The PC4 23400 rating matches platforms specifying this speed grade. It is not for desktop boards that accept only unbuffered DIMMs.

Straightforward DIMM installation

Align the notch with the slot key and press until the ejectors latch; the registered buffer adds negligible physical effort. The usual issue is mixing registered and unbuffered modules in the same channel, which prevents the system from posting.

Steady throughput under load

Registered signalling and 1.20V operation keep electrical loading predictable during sustained workloads. CL21 21-21-21 timings deliver consistent latency without the jitter seen in consumer modules pushed beyond spec.

Questions about this item

How do I confirm the module is running at 2933 MHz and CL21 after installation?

Enter the server BIOS or use a hardware monitoring tool to verify the memory speed reads DDR4 2933 (PC4 23400) and the CAS latency shows 21-21-21 timing at 1.20V.

What is included with the HPE P00924-B21 and what must be purchased separately?

The package contains a single 32GB registered DDR4 2933 module. Additional modules for multi-channel configurations or higher total capacity must be bought separately.

When should I choose this 32GB 2Rx4 registered module over other capacities?

Select this model when your server requires 32GB per slot with registered 2Rx4 organisation, DDR4 2933 speed and CL21 latency at 1.20V.
