NEMIX RAM 32GB DDR4 2933 ECC RDIMM

This NEMIX RAM module provides 32GB of DDR4 2933 memory in a single 288-pin ECC registered DIMM. It operates at 1.20V with CL21 latency and a 2Rx4 rank configuration. The part is built for the Dell PowerEdge MX840c server platform.

Suited for Dell PowerEdge MX840c capacity upgrades

This module fits administrators expanding memory in a Dell PowerEdge MX840c that requires registered ECC DDR4 at 2933 MT/s. It is not for systems needing unbuffered UDIMMs, non-ECC memory, or speeds other than DDR4 2933. Buyers with different server models or desktop platforms should verify their exact memory requirements first.

Registered ECC DDR4 2933 288-pin form factor

The decisive specification is the registered ECC DDR4 2933 288-pin RDIMM form factor. Only platforms designed for registered ECC DDR4 at this speed and pin count can use this module. Confirm the server memory architecture matches these attributes before purchase.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the Dell PowerEdge MX840c memory slots?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor required by the PowerEdge MX840c.

What is the correct seating technique for the registered ECC module, and what step do installers often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module height is even across the channel.

When should the 32GB 2Rx4 CL21 ECC RDIMM be replaced in a production server?

Replace it if the system logs corrected ECC errors that exceed the platform threshold or if memory diagnostics report uncorrectable failures.
