256GB ECC LRDIMM kit for ASRock servers

This 256GB kit contains eight 32GB DDR4 2400 modules built for ASRock Rack EPYCD8-2T boards. Each stick runs at 1.2V with CL17 latency and 2Rx4 organisation. The load-reduced design lowers electrical load on the memory controller for high-density server deployments.

Sustained load behaviour with load-reduced ECC

Load-reduced buffering keeps signal integrity stable when all eight slots are populated under continuous enterprise workloads. ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long compute runs. The 1.2V operation helps limit thermal output inside dense chassis.

Installing eight LRDIMMs in a server board

Modules are keyed 288-pin DDR4 and seat vertically in the board’s DIMM slots; no heat spreaders means tighter slot spacing is not an issue. The kit is validated for the ASRock Rack EPYCD8-2T, so firmware training usually completes on first boot. Builders using other platforms must verify LRDIMM support and qualified vendor lists before purchasing.

Questions about this item

How much heat and power does the 256GB DDR4 2400 LRDIMM kit draw when running continuously?

Each 32GB module operates at 1.2V with a 2Rx4 load-reduced design that lowers electrical load on the memory bus, helping keep system thermals manageable during 24/7 server workloads.

What must the motherboard provide for these 288-pin ECC LRDIMMs to function?

The board needs DDR4 LRDIMM slots that support 2Rx4 registered ECC modules at 1.2V and a BIOS qualified for 2400 MT/s PC4-19200 operation.

Will the CL17 2400 MT/s modules run reliably alongside older DDR4 2666 sticks already in the server?

The memory controller will down-clock all populated channels to the lowest common speed, so 2666 MT/s modules will run at 2400 MT/s with CL17 timings when mixed with this kit.
