System-specific DDR5 server memory

NEMIX RAM MR38400-314K12 is a 384GB kit of twelve 32GB DDR5 4800 ECC RDIMM modules built for SuperMicro FatTwin and SuperServer platforms. IT teams upgrading SYS-F521E3-RTB, SYS-F511E2-RT or X13SEFR-A systems use this kit to fill all slots with registered, 1Rx4 memory that runs at 1.1V.

Registered ECC RDIMM at CL40

Each module is a 288-pin DDR5 RDIMM with on-die ECC and a CAS latency of 40. The registered buffer and 1Rx4 organisation are required by the target SuperMicro motherboards, so the kit will not work in consumer boards or unbuffered slots.

Low-voltage operation without heat spreaders

The modules operate at 1.1V and ship without heat spreaders, relying on server chassis airflow for cooling. In a populated FatTwin node the DIMMs stay within thermal limits at stock speed, and the registered design keeps power draw predictable under sustained load.

Preguntas sobre este artículo

What does the 4800 MT/s rating mean when the modules are installed in a Supermicro server?

The kit will run at DDR5-4800 (PC5-38400) with CL40 latency at the standard 1.10 V, provided the platform memory controller supports that speed.

How does the ECC RDIMM interface affect usable capacity and speed on these boards?

Registered ECC modules add a clock cycle for the register, so the memory controller sees 384 GB of protected capacity at the rated DDR5-4800 data rate.

Will the 288-pin DDR5 RDIMM sticks fit the DIMM slots on a Supermicro FatTwin or SuperServer system?

Yes, the 288-pin DDR5 RDIMM form factor matches the slots on the listed Supermicro FatTwin and SuperServer models.
