Purpose-built kit

This 256GB kit contains eight 32GB DDR5 4800 CL40 registered ECC RDIMMs built for the ASUS RS720A-E12-RS12 2U dual-processor server. The modules run at 1.1V and use a 1Rx4 layout with major OEM DRAM chips. They are validated for that specific platform and ship new.

Fit and limits

IT teams populating the full eight-slot capacity of an RS720A-E12-RS12 will find this kit matches the board’s registered ECC requirement. Builders using consumer motherboards, workstations that need unbuffered DIMMs, or servers that demand a different speed grade or rank configuration should look elsewhere.

Deciding spec

The registered ECC RDIMM form factor is the single specification that determines whether this kit fits the target server; only platforms designed for registered DDR5 ECC modules can use it.

Perguntas sobre este artigo

What limits sustained throughput on the 4800 MT/s DDR5 kit during continuous load?

The 1Rx4 rank organisation and CL40 latency set the bandwidth ceiling; registered ECC buffering adds one cycle per command, so sustained throughput is governed by the DDR5-4800 data rate rather than thermal throttling.

How much heat and noise do the 1.10 V modules add when the server runs all day?

Modules run at 1.10 V with no heat spreaders, so they add minimal thermal load and zero acoustic noise; system fans dominate both temperature and sound inside the ASUS RS720A-E12-RS12 chassis.

Which motherboard and CPU combination must already be present for this 256 GB kit to function?

The kit is validated for the ASUS RS720A-E12-RS12 dual-processor server motherboard; compatible DDR5-4800 registered ECC support in the installed CPUs is required for the 8×32 GB modules to initialise.
