Server Memory Kit

This NEMIX RAM kit provides 128GB of DDR5 4800 ECC registered memory in a dual 64GB module configuration. It operates at 1.1V with CL40 latency and uses a 2Rx4 rank structure on 288-pin RDIMMs. The modules are validated for specific SuperMicro CloudDC SuperServer platforms.

Suited For

This memory suits administrators upgrading SuperMicro SYS-621C-TN12R, SYS-611C-TN4R or SYS-121C-TN2R servers where registered ECC DDR5 is required. It is not for desktop PCs, workstations needing unbuffered DIMMs or systems that cannot accept registered modules or the DDR5 4800 standard.

Capacity & Headroom

The 128GB total capacity handles large virtualisation workloads, in-memory databases and multi-tenant container clusters. Headroom remains for adding further kits if the motherboard provides additional slots. Workloads exceeding 128GB or requiring speeds above DDR5 4800 will need a different configuration.

Questions about this item

Does this 128GB DDR5 4800 kit require a SuperMicro motherboard with 288-pin DDR5 RDIMM slots?

Yes, the 2x64GB modules are 288-pin DDR5 RDIMMs built for SuperMicro CloudDC SuperServer platforms such as SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R.

Can I mix these CL40 1.1V ECC RDIMMs with slower DDR5 memory already installed in the server?

The motherboard will run all populated slots at the lowest common speed and latency, so older DDR5 modules will force this kit down to their slower timing.

How do I confirm the 128GB kit is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to verify 4800 MT/s, CL40, 1.1V and ECC registered status for each 64GB module.
