Capacity and form factor

This NEMIX RAM kit supplies 768GB of DDR5 memory across twelve 64GB registered DIMMs. It is built for the ASUS RS720A-E12-RS24U 2U dual-processor server and uses 288-pin RDIMM modules that run at 4800MT/s with a CL40 latency. The modules operate at 1.1V and carry ECC for data integrity in mission-critical workloads.

Suitable systems and limitations

The kit targets administrators upgrading the named ASUS 2U server to its maximum supported density with validated, stress-tested modules. It is not intended for workstations or consumer motherboards that cannot accept registered ECC DDR5 RDIMMs, nor for platforms limited to lower single-DIMM capacities or different pin layouts. Builders needing unbuffered memory or a different form factor should look elsewhere.

Deciding specification

The registered ECC RDIMM interface combined with twelve 64GB modules at DDR5 4800 CL40 determines whether this kit matches the server's qualified memory list. Only systems qualified for 2Rx4 registered DDR5 at this speed and capacity will POST reliably with the full 768GB installed.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots in the ASUS RS720A-E12-RS24U 2U server?

Yes, the kit is built specifically for that model and uses the standard 288-pin DDR5 RDIMM form factor required by the server.

What is the correct way to populate the 12 modules across the dual-processor board, and what step is often missed?

Follow the motherboard manual for the exact slot sequence per CPU; the step most often missed is locking both ejector clips on every module until they click.

When should the 768GB ECC RDIMM kit be checked or replaced in a production environment?

Run a full memory diagnostic after any firmware update or unexpected crash; otherwise plan a health check every 12 to 24 months under sustained load.
