Product Identity

This NEMIX RAM kit delivers 768GB of DDR5 4800 ECC RDIMM capacity across six 128GB modules. It targets Supermicro SuperWorkstation SYS-531A-I and Super X13SRA-TF platforms that require registered server memory.

Installation Notes

The 288-pin DDR5 RDIMM form factor fits compatible Supermicro slots without adapters. Builders must populate all six channels to reach the rated 768GB and verify the motherboard supports 4Rx4 organisation and 1.1V operation.

Suitability

IT teams running memory-intensive server or workstation workloads on the listed Supermicro systems gain maximum supported capacity with ECC protection. Buyers needing unbuffered UDIMMs, lower densities, or compatibility with non-Supermicro platforms should look elsewhere.

Questions about this item

How do I verify the 4800 MT/s speed and CL40 latency are active after installing the six 128 GB modules?

Enter the system BIOS or UEFI and confirm the memory runs at 4800 MT/s with CL40 timings at 1.10 V; the registered ECC design will also report corrected errors in the OS logs if it is functioning correctly.

What ships in the CSE-735D4-1K26B kit and do I need any extra parts for a Supermicro SYS-531A-I?

The box contains six 128 GB 288-pin DDR5 RDIMM modules totalling 768 GB; no additional memory components are required for the listed Supermicro workstation.

Why choose the 768 GB 6-module kit instead of a smaller capacity for the X13SRA-TF motherboard?

The 6 x 128 GB configuration populates all channels for maximum bandwidth and registered ECC capacity, matching the 4Rx4 organisation validated for the Supermicro X13SRA-TF platform.
