Capacity and Interface

This is a single 64GB DDR4 LRDIMM module rated at 2933MHz with CL21 latency and 1.2V operation. It uses a 288-pin form factor, 4Rx4 organisation and load-reduced ECC buffering for server platforms.

Suited for dense EPYC configurations.

The module targets ASRock Rack ROMED8-2T motherboards running AMD EPYC processors where load-reduced memory is qualified. Builders using consumer boards, workstations that require standard registered DIMMs, or systems limited to 2666MHz JEDEC speeds should select a different part.

Deciding specification: 4Rx4 load-reduced

The 4Rx4 LRDIMM architecture reduces electrical load on the memory bus, allowing higher per-slot density on compatible server chipsets. If the platform does not support load-reduced modules, this DIMM will not function.

Questions about this item

How much power does the 1.2 V DDR4 2933 LRDIMM draw under sustained server load?

The module operates at 1.2 V with a CL21 4Rx4 configuration; load-reduced design lowers electrical load on the memory bus during continuous operation.

What motherboard slot and CPU platform are required for this 288-pin ECC LRDIMM?

It requires a DDR4 288-pin LRDIMM slot on an ASRock ROMED8-2T motherboard with an AMD EPYC processor.

Will this 64 GB 4Rx4 PC4-23400 module work alongside existing 2666 MHz DDR4 ECC LRDIMMs?

Yes, the 2933 MHz module will down-clock to 2666 MHz to match slower installed LRDIMMs while maintaining ECC and load-reduced operation.
