Server-grade capacity

This OWC kit delivers 1TB of DDR4 ECC LRDIMM memory across eight 128GB modules, built for Supermicro H12 series motherboards. It targets administrators expanding virtualisation hosts, database servers or high-density compute nodes that require maximum registered capacity per slot.

Platform integration

The 288-pin LRDIMMs operate at 1.2V and fit the H12DSG-O-CPU, H12DST-B, H12DSU-iN, H12SSL-C and H12SSL-i boards without mixing with unbuffered or standard registered DIMMs. Backward compatibility with 2133, 2400, 2666 and 2933MHz bus speeds allows deployment in existing DDR4 infrastructures while the load-reduced design reduces electrical load on the memory controller.

Workload headroom

CL22 latency at 3200MHz supports memory-intensive workloads such as in-memory analytics, large VM fleets and container clusters. The 4Rx4 organisation maximises density per channel, though total capacity is bounded by the eight-module kit and the motherboard's slot count; environments needing more than 1TB per CPU must scale across additional sockets or platforms.

Vragen over dit artikel

Will the CL22 latency limit throughput when the server runs at 3200 MT/s all day?

CL22 is the rated latency at 3200 MT/s; the modules operate at that timing continuously under load.

Do the eight 128 GB LRDIMMs need active cooling when fully populated in a 1U chassis?

The modules have no heat spreader and run at 1.2 V; airflow across the DIMM slots is the only cooling required.

Must the Supermicro board already support 4Rx4 load-reduced DIMMs before I install this kit?

Yes — the motherboard must accept DDR4 288-pin ECC LRDIMM modules at 4Rx4 organisation.
