32 GB DDR4-2933 ECC RDIMM

This 32 GB DDR4-2933MHz CL17 ECC Registered RDIMM is built for servers and workstations that require error-correcting memory. It suits administrators upgrading Dell-compatible platforms where registered modules are mandatory for stability.

Registered dual-rank x4 288-pin module

The module uses a 288-pin RDIMM form factor operating at 1.2 V with a registered dual-rank x4 organisation. This buffering reduces electrical load on the memory controller, allowing higher capacities per channel in multi-socket systems.

Verify registered ECC support and slot count

Before ordering, confirm your motherboard accepts DDR4 registered ECC RDIMMs and has free 288-pin slots. Systems limited to unbuffered non-ECC memory or lacking sufficient slots cannot use this module.

Questions about this item

What data rate does the DDR4-2933MHz interface deliver in practice?

The module operates at 2933 MT/s, so peak bandwidth is capped at the DDR4-2933 standard rate.

Will the 288-pin RDIMM fit my server's memory slots?

It requires a standard 288-pin DDR4 RDIMM slot; the module is 32 GB, dual-rank x4, registered ECC, and runs at 1.2 V.

How do I install the AA579531-AM and what step is often missed?

Power down, open the chassis, align the notch with the 288-pin slot, press firmly until both retention clips click, then verify the BIOS recognises 32 GB at 2933 MHz CL17.
