384GB DDR5 4800 ECC RDIMM kit

This NEMIX RAM kit provides 384GB across four 96GB registered DIMMs built for Thinkmate Supermicro SuperServer 421GE-TNRT and 421GE-TNRT3 platforms. It targets IT teams running virtualised workloads, in-memory databases or heavy container fleets that need maximum capacity per slot.

Sustained-load behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous 4800 MT/s operation at 1.10V. The 2Rx4 organisation and CL40 latency are validated under prolonged stress testing so throughput remains stable when all channels are fully populated.

Pre-order checklist

Verify the motherboard accepts 288-pin DDR5 RDIMMs and that the BIOS supports 96GB density modules in a four-DIMM configuration. Confirm the server chassis has enough clearance for the full kit and that the power budget accommodates the combined 1.1V draw across all slots.

Questions about this item

How much power does the 1.1 V 384 GB kit draw when the server runs continuously?

Each module operates at 1.10 V; total draw depends on the platform's memory controller and workload, so consult the system documentation for exact figures.

What motherboard feature must the buyer already have to use these registered ECC modules?

The board must provide DDR5 RDIMM slots that support registered ECC memory and 2Rx4 organisation.

Will the 4800 CL40 modules run reliably beside older DDR5 sticks I keep in the same chassis?

Mixing speeds or ranks can force the controller to run all channels at the lowest common settings; for guaranteed stability use identical modules across every populated slot.
