64GB DDR4 ECC RDIMM kit for ASRock Rack ROMED8-2T

This 64GB kit contains eight 8GB DDR4 2933 registered DIMMs with ECC and a CAS latency of CL21. It is built for the ASRock Rack ROMED8-2T motherboard and AMD EPYC server platforms that require registered memory. The modules operate at 1.2V and use a 288-pin form factor.

Check motherboard slots

Verify that the ROMED8-2T has eight free DDR4 RDIMM slots and that the installed EPYC processor supports the full 2933 MT/s data rate across all channels. Confirm the system BIOS is updated to recognise 1Rx8 registered modules at this capacity. Ensure the platform requires registered ECC memory rather than unbuffered or load-reduced types.

Fills eight RDIMM slots to deliver 64GB

The kit occupies every slot on a typical dual-socket EPYC board wired for eight DIMMs per processor, providing registered error correction without needing additional modules. No heat spreaders are fitted, so airflow across the bare PCBs must be adequate in dense chassis. The 1.2V operating voltage matches standard DDR4 server power rails.

Questions about this item

Does the kit include eight 8 GB modules or do I need to buy extra sticks?

The kit ships with eight 8 GB DDR4 2933 RDIMM modules, giving 64 GB total; no additional sticks are required.

Why choose this 64 GB 8×8 GB CL21 kit over other capacities?

It matches the ASRock Rack ROMED8-2T validated configuration, providing 64 GB of registered ECC DDR4 at 2933 MT/s with CL21 latency in a single matched kit.

What does the 2933 MT/s rating mean once the memory is installed in the ROMED8-2T?

The modules run at DDR4 2933 (PC4-23400) with CL21 timing at 1.20 V, delivering the rated throughput when the motherboard trains them at that speed.
