Dell PowerEdge R760 512GB Kit

This 512GB kit contains four 128GB DDR5 registered DIMMs built for the Dell PowerEdge R760. It targets IT teams expanding memory capacity in rack servers that require ECC and registered operation. The modules are validated for Dell enterprise platforms and arrive new from the supplier.

4800 MT/s CL40 Registered ECC

Running at DDR5 4800 with CL40 latency and 1.10V, the kit delivers 38400 MB/s bandwidth per module. Four ranks per DIMM (4Rx4) maximise density for virtualisation and database workloads. ECC and registered buffering protect data integrity under sustained load, while the 1.10V operation keeps power draw within server limits.

288-Pin RDIMM Without Heat Spreader

Each module uses the standard 288-pin RDIMM form factor and omits a heat spreader to fit dense Dell chassis airflow paths. Samsung, Micron or Hynix DRAM chips are used depending on supply. The registered design reduces electrical load on the memory controller, allowing full population of available slots in compatible Dell PowerEdge systems.

Questions about this item

Will the 4Rx4 DDR5 4800 modules run with existing DDR5 RDIMMs already installed in a PowerEdge R760?

All four 128 GB modules are 4Rx4 DDR5 4800 CL40 1.10 V registered ECC; matching rank, speed, voltage and latency is required for mixed-population stability.

How can I verify the 512 GB kit is recognised at 4800 MT/s after installation?

Check the system BIOS or iDRAC inventory — it should show 4 × 128 GB DDR5 4800 registered ECC modules running at PC5-38400 with CL40 timings.

Does the MR38400-744K4 kit include heat spreaders or any extra cables?

The kit contains only the four 288-pin DDR5 RDIMM modules; no heat spreaders, cables or additional accessories are supplied.
