System-specific server memory

This NEMIX RAM kit delivers 384 GB of DDR5 registered ECC memory in four 96 GB modules. It is built for the Supermicro H13SRA-F and H13SRA-TF motherboards that require 288-pin RDIMMs. The exact rank, voltage and timing match the board's memory controller so the full capacity is recognised at the rated speed.

Capacity and headroom

The 384 GB total provides substantial headroom for virtualisation hosts, in-memory databases and large-scale analytics workloads. Four 96 GB 2Rx4 modules fill the supported slots at the rated DDR5 6400 transfer rate. Workloads that exceed this capacity or require higher per-module density will need a platform that supports larger registered DIMMs.

DDR5 registered ECC limits

The DDR5 6400 interface operates at 1.10 V with CL52 latency and registered buffering that reduces electrical load on the controller. ECC corrects single-bit errors on the fly to prevent silent data corruption. Systems that do not support registered DDR5 RDIMMs or that limit memory speed below 6400 MT/s cannot use this kit at its specified performance.

Questions about this item

Will this 384 GB DDR5 6400 kit run alongside any existing RDIMMs I keep in my Supermicro H13SRA-F?

The board requires matching registered DDR5 6400 RDIMMs; mixing ranks, speeds or voltages can prevent full-speed operation, so populate remaining slots with identical 96 GB 2Rx4 1.1 V CL52 modules.

How can I verify the kit is operating at DDR5 6400 with ECC active after installation?

Enter the BIOS and confirm the memory frequency reads 6400 MT/s, CL52 timings and that ECC is reported as enabled for all four DIMMs.

What exactly ships in the box and do I need any extra brackets or cables?

The package contains the four 96 GB 288-pin DDR5 RDIMMs only; no heat spreaders, brackets or cables are included or required.
