A-Tech 64GB DDR4 2666 ECC LRDIMM 4Rx4 Samsung M386A8K40BM2-CTD7Q CTD7Y server RAM

64GB DDR4 2666 ECC LRDIMM for Servers

This 64GB module targets server and workstation platforms that require registered ECC memory. It operates at DDR4 2666 speed with CL19 latency and 1.20V voltage. The load-reduced design places less electrical load on the memory controller than standard registered DIMMs. Buyers needing non-ECC or unbuffered memory for consumer boards cannot use this module.

288-Pin DIMM Fits DDR4 Server Slots

The stick uses the 288-pin DDR4 DIMM form factor and requires a motherboard slot wired for DDR4 LRDIMM signalling. Because it is load-reduced, it frees the memory controller to populate more slots per channel than a standard registered DIMM of the same rank. Systems that only accept UDIMM or RDIMM modules will not recognise this part.

64GB Capacity with 4Rx4 Organisation

A single module delivers 64GB using a 4Rx4 Samsung chipset arrangement, giving high density for virtualisation or large dataset workloads. The four-rank layout maximises capacity per slot but may limit the maximum number of modules per channel on some platforms. Workloads exceeding the module count supported by the memory controller will require a different rank configuration.
