Dell PowerEdge R840 upgrade

This 32 GB DDR4 module is built for the Dell PowerEdge R840 server. It uses registered ECC RDIMM architecture to maintain data integrity in multi-socket configurations. The single 32 GB stick fits one 288-pin slot and runs at 2933 MT/s with CL21 latency.

Registered ECC with major OEM chips

The module carries ECC and registered buffering to correct single-bit errors and reduce electrical load on the memory controller. Chips come from Samsung, Micron or Hynix depending on supply. No heat spreader is included, so airflow in the server chassis handles cooling.

DDR4 2933 platform limits

DDR4 2933 is the maximum JEDEC speed this module supports; faster DDR4 rates are not guaranteed. Registered DIMMs cannot be used in unbuffered consumer motherboards. Mixing ranks or speeds may force the system to run at a lower common rate.

Questions about this item

Will the 2Rx4 RDIMM modules need any firmware updates or periodic reseating after installation?

No firmware updates or scheduled reseating are required; the registered ECC design handles error correction in hardware and the module is validated for continuous server operation.

What thermal limit appears first when the 2933 MT/s RDIMMs run at full load in a PowerEdge R840?

The DDR4 chips are rated for standard JEDEC operating temperatures; sustained full-load use stays within that envelope without triggering throttling.

How much power and heat does a single 32 GB 1.2 V CL21 RDIMM add when the server runs 24/7?

At 1.2 V the module draws only a few watts, adding minimal heat that the R840's existing airflow handles without extra cooling.
