Targeted server upgrade

This 768GB kit delivers twelve 64GB DDR5 4800 RDIMM modules built for the ASUS RS720QA-E12-RS8U rack server. Registered ECC operation and a 2Rx4 organisation provide the data integrity and density that virtualisation hosts and database clusters require. The 1.1V voltage matches the platform specification exactly.

Straightforward module installation

Each 288-pin DIMM seats in the standard DDR5 server slots without tools or adapters. The only common issue is populating all twelve slots in the correct channel order; the motherboard manual defines the required sequence for full 768GB recognition. No heat spreaders are fitted, so airflow clearance is unchanged.

Steady throughput under load

Rated at PC5-38400 with CL40 latency, the modules sustain their rated bandwidth during extended compute runs because registered buffering reduces electrical load on the memory controller. ECC correction operates continuously without performance penalty, preventing silent data corruption during multi-hour render or simulation jobs.

Questions about this item

How do I verify the 12 modules are running at 4800 MT/s with CL40 and ECC active after installation?

Enter the server BIOS or UEFI and confirm the memory speed shows 4800 MT/s, the CAS latency reads CL40, and ECC status is reported as enabled for all 12 slots.

What does the 768GB kit contain and is anything else required to populate the RS720QA-E12-RS8U?

The kit includes twelve 64GB 288-pin DDR5 RDIMMs, each rated 1.1 V, 2Rx4, CL40. No additional parts are needed to fill the compatible ASUS 2U4N rack server.

Why choose the 12 x 64GB configuration instead of a smaller capacity for this server model?

The 12-module, 768GB kit matches the maximum supported DIMM count for the RS720QA-E12-RS8U, delivering the highest total capacity while maintaining registered ECC operation at 4800 MT/s.
