256GB DDR5 RDIMM kit for Dell PowerEdge R6625

This 256GB kit contains two 128GB DDR5 registered DIMMs built for the Dell PowerEdge R6625 server. Each module runs at 4800 MT/s with CL40 latency and operates at 1.1V. The 4Rx4 ECC registered design targets enterprise workloads that require error correction and high capacity per slot.

Thermals and power at 4800 MT/s

Running at the standard 1.1V DDR5 voltage keeps power draw low for 128GB modules. No heat spreaders are fitted, so airflow through the chassis handles cooling. Registered buffering adds minimal latency while maintaining signal integrity across the 288-pin interface during normal operation.

Behaviour under sustained load

Modules are stress tested under load to verify stability for continuous server duty. The 4Rx4 organisation delivers high density without exceeding the platform electrical limits. ECC correction operates continuously during extended compute or virtualisation tasks to maintain data integrity.

Preguntas sobre este artículo

How do I install the 288-pin DDR5 RDIMM modules in the PowerEdge R6625 and what step is often missed?

Power down the server, open the chassis, align the notch on each 128GB module with the slot key, press firmly until the ejector clips lock, then verify in BIOS that both 4Rx4 modules are detected at 4800 MT/s.

What maintenance or replacement will the ECC registered memory need over its service life?

No scheduled maintenance is required; the modules have no heat spreader and operate at 1.10 V, so only a firmware update or a failed DIMM detected by ECC scrubbing would prompt replacement.

What limit appears first when the 256GB kit runs sustained workloads at CL40?

The CAS latency of 40 cycles at 4800 MT/s sets the timing boundary, while the 1.1 V supply and registered design keep signal integrity stable under continuous load.
