Dell-Compatible 64GB LRDIMM

This 64GB DDR4-2666 CL15 ECC LRDIMM is built for Dell servers that require load-reduced registered memory. The 4Rx4 organisation and 1.20V operating voltage match the OEM A9781930 specification. It suits administrators who need to maximise installed capacity on supported platforms. Buyers whose systems only accept standard RDIMMs or lower-density modules cannot use this product.

Thermals and Power Draw

Operating at the standard DDR4 voltage of 1.20V, the module draws nominal power for its density and speed. The load-reduced buffer reduces electrical load on the memory bus, which helps maintain signal integrity across fully populated channels. No active cooling is present on the DIMM itself; airflow within the server chassis handles heat dissipation.

Major-Brand Components

Each stick uses Samsung, SK Hynix or Micron DRAM, the same suppliers Dell uses for its branded modules. This equivalence is intended to preserve existing service contracts when the memory is installed. A lifetime warranty backs the compatibility claim, though the terms are administered by the module vendor rather than the OEM.

Questions about this item

How do I install this 288-Pin DDR4 LRDIMM in a Dell server and what step is often missed?

Align the notch on the 288-Pin module with the slot key, press firmly until both side clips click, then verify the system sees all 64GB at DDR4-2666 CL15 in BIOS.

What maintenance or replacement will this 4Rx4 ECC LRDIMM need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and the module should only be replaced if the server logs uncorrectable memory errors.

What limit appears first when this 1.20V 64GB module runs sustained workloads?

The DDR4-2666 CL15 timing and 1.20V voltage cap throughput; sustained heavy loads hit the rated bandwidth ceiling before thermal throttling becomes a factor.
