System-specific DDR5 kit

This 384 GB memory kit contains six 64 GB DDR5 modules built for the ASUS RS720A-E12-RS12 dual-processor server. Each stick runs at 4800 MT/s with CL40 latency and operates at 1.1 V. The registered ECC design adds error correction and signal buffering for stable operation under heavy workloads.

Suited for exact ASUS server upgrades

IT teams refreshing or expanding the named 2U platform can install this kit without compatibility guesswork. Builders targeting a different motherboard, a workstation, or a consumer desktop should look elsewhere because the module registration and density are tuned for this specific server model.

Registered ECC DDR5 specification

The modules use 288-pin 2Rx4 DDR5 RDIMM packaging with on-die ECC and registered signalling. That combination is the single attribute that determines whether the memory will post and run reliably in the target ASUS server.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the ASUS RS720A-E12-RS12 server motherboard?

Yes, the 288-pin DDR5 RDIMM form factor matches the memory slots on the ASUS RS720A-E12-RS12 server motherboard.

What is the correct order for installing the six 64 GB modules across the two processor sockets?

Populate the slots for the first CPU completely before adding modules to the second CPU, following the channel sequence in the server manual.

How often should the ECC registered memory be tested for correctable errors in this 384 GB kit?

Run a full memory diagnostic at least once per quarter and monitor the system event log daily for corrected ECC events.
