NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 4800 ECC RDIMM module is built for Supermicro SuperWorkstation SYS-531A-I systems requiring registered memory. It operates at 1.10V with CL40 latency and uses a 288-pin form factor. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron or Hynix.

Suited for Supermicro workstation upgrades needing

This module fits builders expanding a compatible Supermicro platform with registered DDR5 memory. It is not for systems that require unbuffered UDIMMs, non-ECC modules, or speeds beyond the 4800 MT/s rating. Buyers needing higher capacities per slot or lower latencies should look at other configurations.

Straightforward DIMM installation

Installation follows typical server DIMM procedures: power down, open the chassis, align the 288-pin key, and press firmly until the ejectors lock. The most common issues are mixing registered and unbuffered modules, populating slots in the wrong order per the motherboard manual, or forgetting to enable ECC in the BIOS.

Questions about this item

Does this DDR5 4800 1.1V RDIMM require a Supermicro X13SRA-TF motherboard to operate?

The module is built for Supermicro SuperWorkstation SYS-531A-I with X13SRA-TF and needs a DDR5-capable registered DIMM slot running at 1.1V.

Can this 288-pin CL40 ECC RDIMM share memory channels with existing DDR5 4800 registered modules in the same server?

Yes, matched DDR5 4800 1.1V CL40 1Rx8 registered DIMMs can populate open slots on the same channel following the motherboard population rules.

How can I verify the 16GB 1Rx8 ECC RDIMM is recognised at the rated 4800 MT/s after installation?

Check BIOS memory information or OS tools such as dmidecode to confirm 16GB, DDR5-4800, ECC registered, 1Rx8 operation at 1.1V.
