1TB DDR5 ECC RDIMM kit for Supermicro workstations

This NEMIX RAM kit delivers 1TB of DDR5 4800 registered ECC memory across eight 128GB modules. It is built for Supermicro SuperWorkstation SYS-531A-I and compatible X13SRA-TF platforms that require 288-pin DDR5 RDIMMs with 4Rx4 organisation.

Verify DDR5 RDIMM support and 4Rx4 population rules

Confirm your motherboard accepts DDR5 registered DIMMs at 4800 MT/s and can populate eight slots with 4Rx4 modules. The kit runs at 1.1V with CL40 latency and has no heat spreaders, so ensure airflow meets server-grade thermal requirements.

Suits IT teams scaling Supermicro memory to 1TB

Ideal for administrators expanding compatible Supermicro workstations or servers to the full 1TB capacity using validated modules. Not suited for consumer desktops, laptops or any platform that cannot use registered ECC DDR5 RDIMMs.

Questions about this item

Does the kit include anything besides the eight 128 GB DDR5 4800 CL40 288-pin ECC RDIMM modules?

The package contains only the eight 128 GB DDR5 4800 CL40 288-pin ECC RDIMM modules; no cables, brackets or software are supplied.

When should I choose the 1 TB (8 × 128 GB) DDR5 4800 CL40 ECC RDIMM kit instead of a smaller capacity?

Choose this 1 TB kit when your Supermicro SYS-531A-I or X13SRA-TF workstation needs the maximum registered ECC capacity across all eight slots for large datasets or virtualization.

What does the DDR5 4800 CL40 4Rx4 1.10 V specification mean for real-world throughput in a Supermicro SYS-531A-I?

The modules run at 4800 MT/s with CL40 latency and quad-rank 4Rx4 organisation at 1.10 V, delivering the rated PC5-38400 bandwidth when the platform populates all eight channels.
