System-Specific DDR5 ECC RDIMM Kit

This NEMIX RAM kit delivers 64GB of DDR5 4800 ECC registered memory in four 16GB modules. It is built for the SuperMicro SuperWorkstation SYS-531A-I and compatible X13SRA-TF platforms. The 1Rx8 organisation and 1.1V operation suit enterprise workloads that require error correction and registered buffering.

Verify Motherboard Slot Count And Population Rules

Before ordering, confirm that your SuperMicro system accepts four 288-pin DDR5 RDIMMs at 4800 MT/s with CL40 timing. Check the platform documentation for maximum supported capacity per channel and any required slot-filling sequence. The modules have no heat spreaders, so ensure airflow meets the vendor's thermal guidelines.

Kit Configuration Simplifies Deployment

The matched set of four 16GB modules removes the guesswork of mixing ranks or speeds. Registered ECC operation helps maintain data integrity under sustained load. No additional software or accessories are included; the value is in the pre-validated compatibility and the 1Rx8 density optimised for the target workstation.

Questions about this item

What comes in the CSE-735D4-1K26B kit and do I need anything else to install it?

The kit contains four 16 GB DDR5 4800 CL40 ECC RDIMM modules for a total of 64 GB. No extra parts are required; the modules plug directly into the 288-pin slots of a compatible Supermicro system.

Should I choose this 64 GB 4800 MHz kit or a different capacity for my Supermicro SYS-531A-I?

This 4 × 16 GB kit matches the SYS-531A-I’s four-channel architecture and fills all slots at the platform’s native 4800 MT/s speed. Select it when you need the full 64 GB capacity; choose a smaller kit only if your workload fits in less memory.

What does the 4800 MT/s rating mean once the memory is running in the workstation?

The modules operate at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, delivering the rated bandwidth and error-correction the Supermicro X13SRA-TF platform expects for registered server workloads.
