Capacity and kit layout

This NEMIX RAM kit delivers 128 GB in two 64 GB modules. It is DDR5 4800 registered ECC RDIMM memory built for the Supermicro SuperWorkstation SYS-531A-I. The kit targets IT professionals who need maximum capacity in a dual-channel server or workstation platform.

Build integration and platform fit

Each module is a 288-pin DDR5 RDIMM with 2Rx4 organisation and operates at 1.1 V. The registered design places a buffer on the command bus, reducing electrical load on the Supermicro X13SRA-TF motherboard. ECC circuitry corrects single-bit errors to protect data integrity in mission-critical workloads. No heat spreader is fitted, so airflow across the DIMM slots must be adequate.

Ideal buyer and limitations

This kit suits administrators expanding a compatible Supermicro workstation to 128 GB with validated ECC registered modules. Buyers who need unbuffered UDIMMs, lower latency timings, or memory for consumer desktop platforms should look elsewhere. Systems that do not support DDR5 RDIMM registered ECC memory cannot use this kit.

Highlights

  • 128 GB DDR5 capacity for heavy server workloads

Questions about this item

Will the 1.10V voltage of these DDR5 modules limit sustained performance in the SuperMicro SYS-531A-I?

The 1.10V operating voltage is the standard JEDEC specification for DDR5 and is fully supported by the SuperMicro SYS-531A-I workstation platform for continuous operation.

How much heat do two 64GB DDR5 4800 CL40 RDIMMs generate under all-day load in a CSE-735D4 chassis?

As standard registered DDR5 modules without heat spreaders, they rely on system airflow; the CSE-735D4 chassis fan wall provides directed cooling across the DIMM slots for sustained workloads.

Does the SuperMicro X13SRA-TF motherboard require a specific BIOS version to recognise this 2Rx4 128GB kit?

The kit is validated for the SuperMicro X13SRA-TF motherboard in the SYS-531A-I; current BIOS releases support 64GB 2Rx4 RDIMM density per slot at DDR5 4800 speeds.
