512GB ECC RDIMM kit for Supermicro H12SSL and H12SSW

This 512GB kit contains eight 64GB DDR4 3200 registered ECC modules built for Supermicro H12SSL-CT, H12SSL-NT, H12SSW-iNR and H12SSW-NTR motherboards. It is designed for workstation and server platforms that require registered memory and will not operate in standard desktop computers.

Registered ECC modules with CL22 timing

Each 288-pin DIMM runs at 1.2V with CL22 latency and a 2Rx4 organisation. The registered buffer and on-die ECC provide the data-integrity and signal-stability that multi-socket server boards demand. Mixing these modules with unbuffered or load-reduced memory is not supported.

Eight-module capacity for high-density workloads

The 512GB total gives headroom for large virtual-machine fleets, in-memory databases and heavy rendering jobs on the listed Supermicro platforms. Systems limited to fewer than eight DIMM slots or lower maximum memory per slot cannot use the full kit.

Frågor om den här produkten

Will the 64 GB 2Rx4 RDIMMs need any replacement or firmware updates during their service life?

The modules carry a limited lifetime warranty with free tech support and advanced replacement, so any defective DIMM is swapped without extra cost.

What limit appears first when all eight 3200 MT/s DIMMs run sustained workloads?

The memory controller on the Supermicro H12SSL board caps total bandwidth at the rated 3200 MT/s, so throughput hits that ceiling before thermals or voltage do.

How much extra power and heat do the eight 1.2 V registered DIMMs contribute under continuous load?

Each 64 GB RDIMM operates at 1.2 V; combined draw is proportional to the 512 GB capacity, and with no heat spreaders the modules rely on chassis airflow for cooling.
