ASRock EPYC 64GB DDR4 RDIMM

This registered ECC module is built for ASRock Rack ROMED8-2T motherboards running AMD EPYC processors. It targets server and workstation builders who need validated, single-stick capacity upgrades for mission-critical workloads. The DDR4 2933 speed and 1.20V operation match the platform's native memory controller specifications.

Registered ECC with 2Rx4 organisation

The module uses a 2Rx4 rank configuration and registered buffering to reduce electrical load on the memory bus. This allows the motherboard to populate more slots reliably at the rated 2933 MT/s data rate. CL21 latency and PC4-23400 bandwidth are the decisive figures for compatibility with the target EPYC platform.

64GB single-module capacity

One 288-pin DIMM delivers 64GB, letting you scale total system memory in large increments without consuming extra slots. It handles virtualisation hosts, database buffers and large dataset caching comfortably. Workloads that exceed per-channel rank limits or require higher frequencies than 2933 MT/s will need a different module class.

Questions about this item

What does the DDR4-2933 CL21 rating mean once the module is installed in a server?

The module operates at 2933 MT/s with a CAS latency of 21 cycles, providing registered ECC DDR4 bandwidth for the ASRock EPYC platform.

How does the PC4-23400 designation limit real-world throughput?

PC4-23400 specifies a peak transfer rate of 23400 MB/s; actual throughput depends on the motherboard memory controller and populated DIMM slots.

What physical requirements must the chassis and motherboard meet for this 288-pin RDIMM?

It requires a standard 288-pin DDR4 RDIMM socket with 1.2 V support and enough vertical clearance for a module without a heat spreader.
