64GB DDR5-4800 ECC RDIMM module

This 64GB DDR5-4800 registered DIMM delivers ECC error correction for data integrity in the ASUS RS520A-E12-RS24U server. It operates at 1.10V with CL40 latency and a 2Rx4 organisation across 288 pins. The module is validated for that specific 2U single-socket platform.

Suitable for and not suitable for

IT teams expanding memory in an ASUS RS520A-E12-RS24U will find guaranteed compatibility and registered buffering for heavy workloads. Builders using desktop boards, laptops or non-ASUS servers cannot use this registered ECC DIMM. Buyers needing unbuffered memory or a different form factor must select another part.

DDR5 4800 CL40 registered ECC specification

The decisive specification is the DDR5 4800 CL40 registered ECC RDIMM standard required by the RS520A-E12-RS24U memory controller. Only modules matching this exact speed, latency, voltage and registration type will initialise correctly in the server.

Questions about this item

How do I install this 64GB DDR5 4800 RDIMM in the ASUS RS520A-E12-RS24U server, and what step is often missed?

Power down the server, open the chassis, align the 288-pin module with the DDR5 slot key, press firmly until the ejector tabs click, then verify in BIOS that the 2Rx4 rank and CL40 timing are detected at 1.10V.

What maintenance or replacement will this NEMIX RAM module need over its service life?

The DDR5 RDIMM has no moving parts or heat spreader; only periodic dust removal from the 288-pin contacts is required, and replacement occurs only if ECC logs report uncorrectable errors.

What limit appears first when this 64GB DDR5 4800 CL40 module runs sustained workloads?

The CL40 CAS latency at 4800 MT/s sets the baseline throughput ceiling; sustained heavy access will saturate the PC5-38400 bandwidth before thermal or voltage limits are reached.
