64GB DDR5 ECC RDIMM module

This 64GB DDR5 4800 CL40 registered DIMM operates at 1.10V and uses a 2Rx4 organisation. It is built with major OEM DRAM from Samsung, Micron or Hynix and carries ECC for data integrity. The module fits 288-pin DDR5 server slots and is validated for the ASUS RS720Q-E11-RS8U 2U4N high-density server.

Target systems and alternatives

The part suits administrators upgrading or populating the named ASUS 2U4N platform where registered ECC memory is required. It is not suitable for workstations or desktops that accept only unbuffered non-ECC modules. Buyers needing a different capacity, speed or rank configuration should select another module.

Deciding specification

Registered ECC with a 2Rx4 layout at DDR5 4800 is the single attribute that determines compatibility with the target server. The motherboard’s memory controller expects registered signalling and on-die error correction at this data rate. Verify the qualified-vendor list before ordering.

Questions about this item

Will the 2Rx4 rank layout ever require a firmware update or module replacement as the server scales?

The module is a 2Rx4 registered DIMM validated for the ASUS RS720Q-E11-RS8U; rank configuration is fixed and does not change with firmware.

At continuous load, does the CL40 latency or the 4800 MT/s data rate become the bottleneck first?

Sustained throughput is capped by the 4800 MT/s bus speed; CL40 only adds a fixed cycle delay per access.

With no heat spreader and 1.10 V operation, how hot and loud does the DIMM get in a 2U chassis running 24/7?

Registered DDR5 at 1.10 V runs cool enough for passive airflow in a 2U server; no active cooling or audible noise is produced by the module itself.
