512GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 512GB across eight 64GB DDR5 4800 ECC registered DIMMs. It is built for Supermicro GPU SuperServer systems such as the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. The modules run at 1.1V with CL40 latency and use a 2Rx4 organisation.

For Supermicro Server Upgrades

The kit suits administrators expanding memory in the listed Supermicro platforms where registered ECC DDR5 is required. It is not for consumer desktops, workstations that accept only unbuffered DIMMs, or any system that cannot address 512GB in eight slots.

Eight Slots Fully Populated

With all eight slots filled the server reaches its 512GB capacity, supporting large virtualisation clusters, in-memory databases and GPU-accelerated workloads. Headroom ends at this limit; configurations needing more memory would require a platform with additional DIMM slots or higher-density modules.
