Dell PowerEdge R760 server memory

This 128GB DDR5 RDIMM is built for the Dell PowerEdge R760 platform. Registered ECC operation protects data integrity in mission-critical workloads. The module runs at 4800 MT/s with a CL40 latency profile. IT teams can deploy it to expand memory capacity in validated configurations.

288-pin registered DIMM build

The registered design adds a buffer that reduces electrical load on the server memory controller. ECC circuitry corrects single-bit errors without halting the system. Absence of a heat spreader keeps the module height low for dense chassis layouts. The 1.1V operating voltage aligns with DDR5 baseline power requirements.

OEM-grade chipset validation

Major OEM Samsung, Micron and Hynix components are stress-tested under load before shipment. The MR38400-744K1 part number confirms Dell-qualified compatibility for the R760 rack server. Registered ECC RDIMM format is required; unbuffered or non-ECC modules will not function in this platform. Lifetime replacement coverage backs the hardware.

Questions about this item

What speed does the DDR5 4800 interface cap at in practice?

The DDR5 4800 interface runs at 4800 MT/s, labelled PC5-38400, with a CAS latency of CL40.

What physical slot and clearance does the 288-pin RDIMM need?

It requires a standard 288-pin DDR5 RDIMM slot; the module has no heat spreader, so it fits in tight server bays.

How is the module installed, and which step is often missed?

Align the notch, press firmly until the retention clips click, then verify the system recognises the full 128GB capacity in BIOS.
