256GB DDR4 ECC LRDIMM kit for ASRock EPYC servers

This 256GB kit contains four 64GB DDR4 3200 CL22 ECC LRDIMM modules designed for the ASRock Rack ROMED8-2T AMD EPYC motherboard. It targets administrators expanding memory capacity on compatible server platforms.

Load-reduced registered design

Each module uses a 4Rx4 organisation and operates at 1.2V without a heat spreader. The load-reduced buffer reduces electrical load on the memory controller, allowing high-density population on supported server boards.

Verify motherboard qualification

Confirm the ROMED8-2T qualification list approves 64GB 4Rx4 LRDIMMs at 3200 MT/s and check the required slot-filling order in the board manual. Ensure the BIOS version supports this capacity and rank configuration before installation.

Questions about this item

What DDR4 speed does PC4-25600 actually run at?

PC4-25600 corresponds to DDR4 3200, so the kit operates at 3200 MT/s with a CAS latency of CL22.

Will these 288-pin LRDIMMs fit the ASRock Rack ROMED8-2T motherboard?

Yes, the 288-pin DDR4 LRDIMM form factor matches the ROMED8-2T's DIMM slots for AMD EPYC processors.

Do I need to populate all four channels for the 256 GB kit to work?

Install one 64 GB module per channel following the motherboard's population order; the system will not boot if slots are filled out of sequence.
