1TB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 1 TB of DDR5 4800 registered ECC memory across sixteen 64 GB modules. It is built for Supermicro GPU SuperServer systems that require 288-pin DDR5 RDIMMs with 2Rx4 organisation and CL40 latency at 1.10 V.

Verify DDR5 RDIMM slot count and population rules

Confirm the server motherboard has sixteen available DDR5 RDIMM slots and supports 2Rx4 registered modules at 4800 MT/s. Check the platform documentation for maximum capacity per channel and any required population order before installing all sixteen modules.

Replaces lower-capacity or slower DDR5 RDIMM sets

The kit upgrades systems running smaller DDR5 RDIMM configurations or slower speeds to the full 1 TB at 4800 MT/s. The jump is worth it when workloads demand maximum registered ECC capacity and the platform can address all sixteen slots.

Questions about this item

Does the 1TB kit ship as 16 separate 64GB modules or are any extra brackets or cables included?

The package contains 16 individual 64GB DDR5 RDIMM modules. No brackets, cables or additional accessories are supplied.

Should I choose the 1TB 16×64GB kit or a smaller capacity for my SuperMicro SYS-821GE-TNHR?

The 1TB kit fills 16 slots with 64GB 2Rx4 modules at DDR5 4800 CL40. Select a smaller kit only if your chassis has fewer than 16 DIMM slots or you need less total capacity.

What does the DDR5 4800 CL40 rating deliver once the modules are installed in a SuperMicro GPU SuperServer?

The modules run at 4800 MT/s with CL40 latency at 1.1V, providing registered ECC bandwidth of PC5-38400 across all 16 slots for stable server workloads.
