64 GB DDR4 ECC LRDIMM for ASRock EPYC

This 64 GB DDR4 2400 CL17 module is built for the ASRock Rack ROMED8-2T motherboard running AMD EPYC processors. It operates at 1.20 V and uses a 288-pin load-reduced form factor with 4Rx4 organisation. The part is new and validated for server workloads requiring registered ECC memory.

Suited for single-slot capacity upgrades

Administrators expanding memory on this specific platform will match the required speed, voltage and rank configuration. Builders targeting other motherboards, consumer CPUs or non-ECC systems should look elsewhere because the load-reduced design and EPYC-specific qualification limit compatibility.

4Rx4 rank layout decides platform fit

The module presents four ranks of x4 chips, a density that the ROMED8-2T memory controller expects. Boards wired for 1Rx4, 2Rx4 or 8Rx4 populations may not initialise this DIMM, so verifying the rank requirement against the system manual is the decisive step.

Questions about this item

How can I confirm the 64GB DDR4 2400 CL17 LRDIMM is running at the correct speed and timings after installation?

Enter the system BIOS or UEFI and verify the memory frequency reads 2400 MT/s with CAS latency 17 at 1.2 V; the module is a 288-pin 4Rx4 load-reduced ECC DIMM so the firmware will report it as registered LRDIMM.

What is included in the package and do I need any extra parts to install it in an ASRock ROMED8-2T EPYC motherboard?

The box contains one 64 GB DDR4 2400 PC4-19200 CL17 1.2 V 288-pin ECC LRDIMM; no additional cables, brackets or heat spreaders are required for installation in the compatible ASRock server board.

Should I choose the 2400 MHz CL17 version or the 2666 MHz variant for my ASRock ROMED8-2T EPYC system?

Select the DDR4 2400 CL17 module (part ML19200-944K1) because it matches the validated speed and latency for the ROMED8-2T; the 2666 MHz label in the series name refers to the broader family, not this specific 2400 MT/s kit.
