64 GB DDR5 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs with ECC and a CAS latency of CL40. The modules run at 1.1 V and use a 288-pin 1Rx4 layout built with major OEM chips. They are designed for the ASUS RS720A-E12-RS12 2U dual-processor server.

Suited for compatible ASUS servers only

This memory is validated for the specific ASUS RS720A-E12-RS12 platform. Builders working on other server models, workstations, or consumer motherboards should look elsewhere because the registered ECC design and vendor-specific qualification will not function in those systems.

Registered ECC RDIMM requirement

The decisive specification is the registered ECC RDIMM form factor; the target server only accepts registered modules with error correction. Unbuffered or non-ECC DIMMs are physically incompatible and will not operate in this system.

Questions about this item

Will the 1Rx4 registered DIMMs need any firmware updates or thermal-pad replacement during their service life?

The modules have no heat spreader and run at 1.10V; they are validated for the ASUS RS720A-E12-RS12 platform and require no scheduled firmware updates or pad changes.

What is the first limit reached when the 4800 MT/s CL40 ECC RDIMMs run at full load continuously?

The CAS latency of CL40 and the 4800 MT/s data rate set the throughput ceiling before thermal or power limits are encountered.

How much noise and heat does the 288-pin DDR5 4800 registered kit produce in a 2U server running all day?

The kit has no onboard fan or heat spreader, operates at 1.10V, and relies on the server’s chassis airflow; it adds no audible noise of its own.
