System-Specific DDR5 Server Memory Kit

This 192GB kit contains six 32GB DDR5 4800 ECC registered DIMMs built for the ASUS RS720QA-E12-RS8U high-density 2U4N rack server. It targets IT teams expanding memory capacity in that exact platform for virtualisation, database or HPC workloads.

Compatibility Check Before Ordering

Verify the server model matches RS720QA-E12-RS8U and that all twelve DIMM slots across the four nodes are free for a full 6-module installation. Confirm the BIOS revision supports 1Rx4 registered DDR5 at 4800 MT/s and that the memory configurator approves a 192GB population per node.

Thermals, Noise and Power Draw

Modules run at 1.10V without heat spreaders, relying on the server’s directed airflow for cooling. Registered buffering and ECC add negligible latency while maintaining signal integrity under sustained load. Power consumption scales linearly with the six-module population in normal operation.
