Server-grade DDR5 ECC RDIMM kit

This 768GB memory kit contains six 128GB registered DDR5 modules built for ASUS RS720Q-E11-RS8U high-density servers. It targets IT teams who need maximum capacity per node for virtualization, databases or in-memory analytics.

768GB across six channels at DDR5 4800

Each 4Rx4 module runs at PC5-38400 with CL40 latency and 1.10V. The registered design and on-die ECC keep data integrity intact under sustained load. Capacity scales to the platform limit, while the 4800 MT/s speed ceiling is set by the memory controller.

Replaces smaller RDIMM sets

Swapping a partial population for this uniform 6×128GB kit removes rank-mismatch bottlenecks and simplifies spares management. The upgrade pays off when workloads hit the previous capacity wall or when ECC error rates climb on older modules.

Questions about this item

Will these 4Rx4 DDR5 4800 modules run alongside existing 2Rx8 DDR5 4800 sticks in the same ASUS RS720Q-E11-RS8U server?

Mixing different rank configurations is not recommended; the server's memory controller expects identical rank and timing settings across all populated slots for stable operation.

How can I verify the 768GB kit is detected at DDR5 4800 CL40 after installation?

Enter the BIOS or use a hardware-inventory tool; the system should report 768 GB total capacity, 4800 MT/s speed and CAS latency 40 for each of the six 128 GB modules.

Does the package include only the six 288-pin RDIMMs or are heat spreaders and installation tools also supplied?

The box contains the six 128 GB DDR5 4800 ECC registered RDIMMs; no heat spreaders or tools are included.
