Capacity and form factor

This is a 384GB DDR5 registered DIMM kit organised as twelve 32GB modules. It targets administrators upgrading Supermicro Hyper SuperServer platforms that require ECC registered memory in a 288-pin layout.

Sustained-load behaviour

Each module operates at 1.1V with a CAS latency of CL40 and a 1Rx4 rank structure. The registered buffer and on-die ECC maintain data integrity during continuous server workloads without a heat spreader.

Deciding specification

Compatibility is limited to the Supermicro SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R systems listed in the supplier data. Buyers with other platforms cannot use this kit.
