16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 4800 ECC RDIMM module provides registered server memory with CL40 latency and 1.10V operation. It uses a 288-pin form factor and 1Rx8 rank configuration built with major OEM chips. The part is validated for Dell PowerEdge R7615 rack servers and carries the MR38400-618K1 part number.

Suited for R7615 capacity upgrades

This module fits administrators expanding memory in a Dell PowerEdge R7615 where registered ECC DDR5 is required. It is not for systems that need unbuffered UDIMMs, non-ECC memory, or speeds above 4800 MT/s. Buyers who want more storage or a different form factor should look at other categories.

Registered ECC with CL40 timing

The single specification that decides fit is the registered ECC DDR5 interface with CL40 timing at 1.10V. Only motherboards that accept 288-pin RDIMMs at this voltage and latency will POST correctly with this module.

Questions about this item

How much power does the 1.10 V DDR5 4800 module draw when the server runs continuously?

The module operates at 1.10 V, the standard voltage for DDR5, so power draw stays low during all-day workloads in the PowerEdge R7615.

What motherboard slot and memory type must the system provide for this 288-pin RDIMM to function?

It requires a DDR5 RDIMM slot with ECC and registered support; the R7615 platform supplies exactly that interface.

Can this 1Rx8 CL40 16 GB stick share channels with other DDR5 ECC registered modules already installed in the R7615?

Yes — matching DDR5 ECC registered specifications allows it to populate open slots alongside identical-rank or mixed-rank modules in the same server.
