Suited for dual-processor servers

This 256 GB kit targets administrators upgrading the ASUS RS720A-E12-RS12 platform with registered ECC memory. The 4800 MT/s DDR5 modules operate at 1.10 V and provide error correction for mission-critical workloads. Builders needing unbuffered DIMMs or non-ECC memory for workstations should look elsewhere.

Deciding specification

The 4Rx4 rank organisation combined with registered ECC RDIMM signalling is the single attribute that determines compatibility with the ASUS RS720A-E12-RS12 server. Only modules matching this exact configuration will initialise correctly in the dual-processor motherboard.

Perguntas sobre este artigo

Do I need an ASUS RS720A-E12-RS12 dual-processor server with DDR5 RDIMM slots to install this 256 GB kit?

Yes. The kit is built for the ASUS RS720A-E12-RS12 platform and uses 288-pin DDR5 RDIMMs, so the server must provide DDR5 registered DIMM sockets.

Will the 4Rx4 organisation and CL40 timing of these modules match the memory controller on the RS720A-E12-RS12?

The modules are qualified for that server model, so the 4Rx4 layout and CL40 latency are supported by its DDR5 memory controller.

How can I confirm the kit is running at DDR5 4800 with ECC active after installation?

Check the system BIOS or an OS tool such as dmidecode; it should report 4800 MT/s, CL40, 1.10 V and ECC enabled for each 128 GB module.
