384 GB DDR5 ECC RDIMM kit

This 384 GB kit contains six 64 GB DDR5 4800 registered DIMMs with ECC. The modules run at 1.1 V and carry a CAS latency of CL40. They are built for the ASUS RS720-E11-RS24U dual-socket 2U server.

Suited for memory-bound server workloads

The 384 GB capacity targets virtualization hosts, database nodes and compute clusters that need maximum registered ECC memory per CPU. Systems limited to lower densities or consumer UDIMM slots cannot use this kit.

Registered ECC with 2Rx4 organization

Each module uses a 2Rx4 layout on a 288-pin DDR5 RDIMM. The registered buffer and on-die ECC maintain signal integrity and data integrity at full population across both sockets.

Questions about this item

Does the 384GB kit include all 6 modules or do I need to buy additional 64GB sticks?

The package contains six 64GB modules for a total of 384GB; nothing else is required to reach that capacity.

Should I choose the CL40 4800MHz version or a different speed for this ASUS RS720-E11-RS24U server?

This kit is built to the exact DDR5 4800 CL40 specification validated for the RS720-E11-RS24U; other speeds are not qualified for this model.

What does the PC5-38400 rating tell me about real-world throughput in this dual-socket system?

PC5-38400 is the JEDEC designation for DDR5 4800; actual bandwidth depends on the CPU memory controller and population rules of the RS720-E11-RS24U.
