32GB DDR5 ECC RDIMM for ASUS RS720A

This 32GB DDR5 4800 CL40 ECC registered DIMM is built for the ASUS RS720A-E12-RS24U dual-processor server. It runs at 1.10V with a 1Rx4 Samsung, Micron or Hynix chipset. The module adds error-correcting, registered memory to supported 2U configurations.

Who should use this and who should not

IT teams upgrading or repairing the specified ASUS 2U server will find guaranteed compatibility. Builders needing unbuffered UDIMMs, non-ECC modules, faster speeds, lower latency, heat spreaders or capacities other than 32GB per stick should look elsewhere.

The specification that decides fit

The part is a 288-pin DDR5 RDIMM with ECC and registered buffering at CL40 4800MT/s. Only systems that accept DDR5 ECC RDIMMs at this exact speed, voltage and rank can use it.

Questions about this item

Will this DDR5 4800 CL40 1Rx4 ECC RDIMM run in my ASUS RS720A-E12-RS24U alongside existing DDR5 modules at the same speed?

Yes — it is a 32 GB DDR5 4800 PC5-38400 1Rx4 1.1 V CL40 288-pin ECC registered DIMM built for that server. Matching speed, voltage, rank and ECC type lets it operate with identical modules.

How can I confirm the module is recognised at 4800 MT/s with ECC active after installation?

Enter the BIOS or UEFI and check the memory information screen: it should show 4800 MT/s, 1Rx4 organisation, 1.1 V and ECC enabled for the new DIMM.

Does the package include only the 32 GB DDR5 4800 CL40 ECC RDIMM or are any extra parts supplied?

The box contains one 32 GB 1Rx4 288-pin DDR5 4800 CL40 1.1 V ECC registered DIMM; no heat spreader, cables or tools are included.
