ASRock Rack ROMED8-2T Compatible DDR4 Kit

This 512GB kit contains eight 64GB DDR4 2933 ECC RDIMM modules built for the ASRock Rack ROMED8-2T motherboard. It targets administrators upgrading AMD EPYC servers that require registered memory with error correction. The modules run at 1.2V and carry a CL21 latency rating.

2Rx4 Registered ECC Configuration

Each module uses a 2Rx4 organisation and the 288-pin RDIMM form factor required by the platform. Registered buffering and ECC protect data integrity under sustained server workloads. The kit operates at the PC4-23400 speed grade specified for this board.

Suited for High-Capacity EPYC Servers

This kit fits deployments that need the maximum supported capacity on the ROMED8-2T. Builders using consumer boards, unbuffered memory slots, or systems limited to lower densities should select a different product.

Questions about this item

What does the 2933 speed rating deliver once the modules are installed in a server?

The kit runs at DDR4 2933 (PC4-23400) with CL21 latency, providing registered ECC bandwidth tuned for the ASRock Rack ROMED8-2T platform.

How does the DDR4 288-pin RDIMM interface limit usable capacity per slot?

Each 64 GB module uses a 2Rx4 organisation on the 288-pin DDR4 RDIMM interface, so eight slots reach the 512 GB total.

What physical clearance does the 288-pin RDIMM kit need inside the chassis?

The modules are standard-height 288-pin DDR4 RDIMMs without heat spreaders, fitting the DIMM slots on the ROMED8-2T motherboard.
