NEMIX RAM RS520A-E12-RS12U 32GB (2x16GB) DDR5 4800 ECC RDIMM memory upgrade

Intended use and audience

This 32 GB DDR5 ECC RDIMM kit is built for the ASUS RS520A-E12-RS12U single-socket 2U server. It targets system administrators and integrators who need registered, error-correcting memory validated for that specific platform. The two 16 GB modules run at 4800 MT/s with a CL40 latency and 1.10 V operation.

Compatibility scope

The modules are qualified only for the named ASUS server model; they will not fit desktop motherboards, workstations requiring unbuffered DIMMs, or servers from other vendors that demand different register timings or pin-outs. Buyers who need consumer DDR5, non-ECC UDIMMs, or memory for a different OEM chassis should look elsewhere.

Decisive specification

Registered ECC RDIMM format with 1Rx8 organisation is the single attribute that determines whether this kit will post in the target server; the platform's memory controller requires registered modules and will reject unbuffered or LRDIMM alternatives.
