SK hynix HMAA8GL7MMR4N-UH 64GB DDR4-2400 ECC LRDIMM server RAM

64 GB DDR4 LRDIMM for servers

This 64 GB DDR4 load-reduced DIMM delivers high-density memory for multi-socket servers and virtualization hosts. ECC protection corrects single-bit errors to maintain data integrity across large memory footprints. The module operates at the standard 1.20 V, keeping power draw predictable in dense configurations. It is not suited for desktop boards that cannot address LRDIMM topology.

CL17 latency at 2400 MT/s with 1.20 V operation

Rated at DDR4-2400 (PC4-19200) with CL17 timings, the module runs at the JEDEC-standard 1.20 V during typical workloads. The load-reduced buffer reduces electrical load on the memory bus, allowing more modules per channel without increasing voltage. Thermal output remains proportional to capacity and bus activity rather than clock headroom. No enthusiast overclocking profiles are defined for this part.

Steady throughput under sustained multi-threaded

Under continuous memory-bound workloads the LRDIMM maintains its rated 2400 MT/s transfer rate without downclocking, because the buffer isolates DRAM timing from channel signalling. ECC scrubbing runs in parallel with normal traffic, so error correction does not introduce latency spikes during extended operations. The 1.20 V rail stays stable as long as the platform supplies within specification. Systems requiring higher frequencies or lower latencies must select different modules.
