Compatible server memory kit

This 64GB kit contains four 16GB DDR5 4800 RDIMM modules built for the ASUS RS720Q-E11-RS8U 2U4N high-density server. Each module runs at 1.1V with CL40 latency and includes ECC and registered buffering for data integrity under load. The 1Rx8 organisation and 288-pin DDR5 form factor match the platform's memory slots exactly. The kit is validated for the specified ASUS server model.

Suited for single-server upgrades.

IT teams upgrading or populating the named ASUS 2U4N server will find drop-in compatibility and tested stability. The registered ECC design supports mission-critical workloads that require error correction. Organisations running mixed server brands or desktop platforms should look elsewhere, as this kit is qualified only for the listed ASUS system.

1Rx8 registered ECC at DDR5 4800

The single-rank 1Rx8 layout with registered ECC at 4800 MT/s is the specification that determines whether this kit matches the server's memory controller requirements. Verify that the platform calls for DDR5 4800 RDIMM modules with these timings and voltage before ordering.

Questions about this item

Does the kit include all four 16 GB modules or must any be purchased separately?

The package contains four 16 GB modules totalling 64 GB; no additional sticks are required.

Why choose the CL40 4800 MT/s version instead of a lower-latency or higher-speed DDR5 kit?

CL40 at 4800 MT/s matches the qualified specification for the ASUS RS720Q-E11-RS8U server, ensuring registered ECC stability without overclocking.

What does the PC5-38400 rating mean for actual throughput in the RS720Q-E11-RS8U?

PC5-38400 is the module's rated peak bandwidth designation at 4800 MT/s; real-world throughput depends on the server's memory controller and workload.
