Axiom 32GB DDR4 2933 Registered ECC Module

This Axiom module delivers 32GB of DDR4 2933 memory with ECC and registered buffering. It operates at 1.20V with a CAS latency of CL21 and uses the standard 288-pin form factor. The part is validated for HP systems.

Suited for HP server upgrades needing registered

Buyers who need unbuffered non-ECC memory for a desktop board should look elsewhere. Systems that cannot accept registered modules or that require a different voltage will not be compatible. Workstations limited to lower capacities per slot should also consider other options.

Verify your HP model supports 32GB registered DDR4

Check the system documentation for maximum capacity per slot and total population rules. Confirm the motherboard accepts 1.20V registered ECC modules at this speed. Ensure the BIOS revision in use recognises the density and timing of this part.

Questions about this item

Does this 288-pin DDR4 2933 registered ECC module require an HP server that supports registered memory?

Yes, the module is registered and ECC, so the HP system must support registered DDR4 memory for it to function.

Can I add this CL21 1.20V stick to an HP server that already has DDR4 2933 registered ECC memory installed?

It will work alongside existing DDR4 2933 registered ECC modules; the system will run at the lowest common speed and latency.

How can I confirm the 32GB module is recognised at DDR4 2933 with ECC active after installation?

Check the BIOS memory information or OS tools — they should show 32GB, 2933 MT/s, and ECC enabled for this slot.
