32 GB DDR4-2933 ECC RDIMM

This Axiom module is a 32 GB DDR4-2933 registered DIMM with ECC and CL21 latency. It runs at 1.20 V and uses the standard 288-pin form factor for DDR4 server memory. The single-stick design delivers 32 GB in one slot.

Suited for ECC registered platforms.

It fits servers and workstations that require registered ECC DDR4 memory at 2933 MHz. Buyers whose platforms only accept unbuffered non-ECC modules should look at something else. Systems that cannot use registered DIMMs will not be compatible.

Registered ECC at 2933 MHz decides fit

The registered ECC design combined with a 2933 MHz data rate is the single specification that determines whether this module works in a given system. Verify that the motherboard or server supports registered ECC DDR4 at this speed before ordering.

Questions about this item

What does DDR4-2933 / PC4-23466 mean for real-world throughput?

The module runs at 2933 MT/s, giving a peak transfer rate of 23466 MB/s; actual bandwidth depends on the server's memory controller and channel population.

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

Yes — it is a standard 288-pin DDR4 RDIMM built to Dell's mechanical and electrical spec, so it seats in any compatible Dell DDR4 RDIMM slot.

Do I need to change any BIOS settings when installing this ECC registered DIMM?

Install the DIMM with the server powered off; most Dell platforms auto-detect ECC and registered mode, but verify the memory mode is not set to "Performance" or "Optimiser" which can disable ECC.
