Compatible server memory kit

This 64GB kit contains four 16GB DDR4 RDIMM modules built for ASRock Rack ROMED8-2T motherboards. It targets IT professionals who need registered ECC memory for AMD EPYC server platforms. The modules run at 2933MHz with a CL21 latency profile.

Straightforward DIMM installation

Each 288-pin module seats in the standard DDR4 RDIMM slots without tools or cables. The registered design adds a clock cycle, so the motherboard must support registered memory or the system will not post. Mixing these with unbuffered DIMMs or populating slots in the wrong order are the most common errors.

Registered ECC with 2Rx8 organisation

The single specification that determines fit is the 2Rx8 registered ECC configuration at 1.2V. Boards that require unbuffered, single-rank or non-ECC modules will not work with this kit.

Questions about this item

How do I confirm the kit runs at 2933 MT/s with CL21 after installation?

Enter the BIOS or UEFI and verify the memory frequency reads 2933 MT/s and the CAS latency shows 21 cycles; the registered ECC modules will also report ECC active in the system health screen.

What comes in the package and do I need extra parts for the ASRock Rack ROMED8-2T?

The box contains four 16 GB DDR4 288-pin RDIMMs for a total of 64 GB; no additional memory components are required for the listed motherboard.

Why choose the 64 GB 2Rx8 registered kit instead of a smaller or unbuffered option?

This 64 GB kit uses 2Rx8 registered ECC modules at 1.2 V, matching the EPYC platform requirements for the ASRock Rack ROMED8-2T, while smaller or unbuffered kits would not provide the same capacity or error correction.
