512GB DDR5 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 4800MHz registered DIMMs with ECC. It targets administrators upgrading the ASUS RS720A-E12-RS12 dual-processor server for virtualisation or database workloads.

DDR5 4800 registered limits

The modules run at 1.10V with CL40 latency and a 4Rx4 organisation. Registered buffering and ECC add command-cycle overhead, so sustained throughput depends on the platform memory controller and population rules.

Tool-less DIMM installation

Modules insert vertically into the 288-pin slots and lock with the retention levers. Common issues include mixing ranks across channels, populating slots in the wrong order for the specific CPU configuration, and forgetting to enable ECC in BIOS.

Perguntas sobre este artigo

Should I choose the 512GB kit or a smaller capacity for the RS720A-E12-RS12 server?

The 512GB kit provides four 128GB modules for maximum supported capacity. Smaller kits are available if your workload does not require the full 512GB.

What does the 4800MHz rating mean once installed in the ASUS RS720A-E12-RS12?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the rated throughput when the server memory controller operates at that speed.

Does the 288-pin DDR5 RDIMM interface limit the 4800MHz speed in practice?

The 288-pin RDIMM form factor is the standard for DDR5 registered memory. The 4800MHz speed is the native JEDEC rate for this module; the server chipset determines the final operating frequency.
