384GB DDR5 ECC RDIMM kit

This 384GB kit contains twelve 32GB DDR5 4800 registered DIMMs built for Thinkmate Supermicro SuperServer 421GE-TNRT platforms. ECC and registered buffering protect data integrity in multi-socket server and workstation workloads. The CL40 latency and 1.10V operation match the platform's qualified memory profile.

288-pin registered modules without spreaders

Each module uses a 1Rx4 organisation on major OEM Samsung, Micron or Hynix die and fits the standard 288-pin DDR5 RDIMM socket. The absence of heat spreaders keeps the profile low for dense server chassis where airflow is directed by the system fans. Registered signalling reduces electrical load on the memory controller at this capacity.

Replaces smaller RDIMM sets when capacity is

The jump is worth it when virtualisation, in-memory databases or large dataset analytics exhaust the current memory ceiling and the server board supports twelve populated slots. Buyers who need fewer than twelve modules or a lower total capacity should select a smaller kit instead.

Questions about this item

What maximum data rate does the DDR5 4800 PC5-38400 interface deliver in practice?

The DDR5 4800 PC5-38400 interface runs at 4800 MT/s, providing a peak bandwidth of 38400 MB/s per module when the platform supports that speed.

What physical slot and clearance does the 288-pin DDR5 RDIMM kit require?

Each 32 GB module uses a standard 288-pin DDR5 RDIMM form factor and has no heat spreader, so it fits any server board with 288-pin DDR5 RDIMM slots and normal DIMM spacing.

How are the 12 modules installed in the Supermicro SuperServer 421GE-TNRT, and which step is often missed?

Populate all 12 slots following the motherboard's population guide; the step often missed is enabling the memory training sequence in BIOS after the first boot.
