64GB DDR4 LRDIMM for ASRock EPYCD8-2T

This 64GB DDR4 3200 load-reduced DIMM is built for the ASRock Rack EPYCD8-2T motherboard. It targets server and workstation administrators who need single-module capacity expansion with ECC protection.

ECC LRDIMM limits at DDR4 3200

Load-reduced buffering lowers electrical load on the memory bus so more ranks can be populated per channel. The trade-off is added latency; this module runs at CL22. Systems must support DDR4 LRDIMM and registered ECC operation or the module will not function.

4Rx4 organisation decides fit

The 4Rx4 rank layout determines whether the motherboard memory controller can address the full 64GB. Verify that the EPYCD8-2T firmware and CPU support 4Rx4 LRDIMM population rules before ordering.

Questions sur cet article

Should I pick a single 64 GB module or multiple smaller modules for the ASRock Rack EPYCD8-2T?

This listing is a single 64 GB LRDIMM (part ML25600-944K1). If your board has free 288-pin slots and the CPU memory controller supports 4Rx4 load-reduced modules, one stick adds 64 GB immediately; add a second identical stick later only if the platform qualifies both ranks together.

What does the 3200 MT/s rating actually deliver once installed in the EPYCD8-2T?

The module runs at DDR4-3200 (PC4-25600) with CL22 latency at 1.20 V. Actual throughput depends on the CPU’s memory controller and how many LRDIMMs are populated per channel; the rated 3200 MT/s is the maximum JEDEC speed this stick supports.

How does the 288-pin LRDIMM interface limit capacity or speed on this motherboard?

The 288-pin DDR4 LRDIMM form factor fits the EPYCD8-2T’s registered DIMM slots. Load-reduced buffering lets the memory controller drive higher capacities like this 64 GB 4Rx4 module, but total system capacity and maximum speed are still capped by the processor’s supported ranks-per-channel and maximum memory frequency.
