Dell PowerEdge R6625 DDR5 ECC RDIMM

This 16GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It is built as a registered ECC RDIMM for Dell PowerEdge R6625 rack servers. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron or Hynix.

Verify DDR5 RDIMM slot availability and ECC support

Confirm your server accepts 288-pin DDR5 RDIMM modules and that the memory controller supports ECC registered memory. Check the maximum capacity per slot and total system limit in the Dell documentation. Ensure the BIOS is updated to recognise DDR5 4800MHz modules.

Registered design with no heat spreader

The registered buffer reduces electrical load on the memory controller for stable operation in dense configurations. Absence of a heat spreader keeps the module low-profile for tight server chassis airflow. The 288-pin connector matches the DDR5 RDIMM standard used in the R6625.

Questions about this item

Does the 288-pin DDR5 module arrive as a single 16 GB stick or do I need to buy additional sticks to reach that capacity?

The module is a single 16 GB stick (1Rx8), so the full capacity is delivered in one piece and no extra sticks are required for 16 GB.

The part number ends in 618K1 — does that identify the only capacity and speed combination available?

Yes, part number MR38400-618K1 corresponds to one 16 GB module running at DDR5 4800 with CL40 latency at 1.10 V.

When installed in a PowerEdge R6625, will the registered ECC module run at the rated 4800 MT/s or does the platform throttle it?

The R6625 supports DDR5 4800 registered ECC DIMMs, so the module will operate at its rated 4800 MT/s with CL40 timings.
