384GB DDR5 ECC RDIMM Kit

This 384GB kit contains six 64GB DDR5 4800 CL40 registered DIMMs built for the ASUS RS720-E11-RS12U 2U dual-socket server. It operates at 1.1V with 2Rx4 organisation and ECC for data integrity. Modules use major OEM chips from Samsung, Micron or Hynix.

Suitability and Limits

Designed for IT teams upgrading memory in the named ASUS 2U server where registered ECC RDIMMs are required. Not for buyers who need unbuffered UDIMMs, desktop DDR5, or capacities beyond the 384GB kit. Systems without DDR5 RDIMM slots cannot use these modules.

Deciding Specification

The registered ECC RDIMM form factor with 2Rx4 rank and CL40 latency at DDR5 4800 decides compatibility. Only motherboards that accept 288-pin DDR5 RDIMMs at 1.1V and support this rank structure will post correctly with this kit.

Highlights

  • 384 GB total capacity from six 64 GB modules
  • DDR5 4800 speed with CL40 latency for responsive server workloads
  • ECC registered design detects and corrects data errors automatically
  • Low 1.10 V operation reduces power draw in dense configurations
  • Validated for ASUS RS720-E11-RS12U 2U dual-socket servers

Questions about this item

Does the DDR5 4800 interface cap real-world throughput at PC5-38400?

Yes, the DDR5 4800 modules are rated PC5-38400, which sets the maximum standard data rate for this kit.

What physical slot and module dimensions are required to fit the ASUS RS720-E11-RS12U server?

The kit uses 288-pin DDR5 RDIMM modules; the server must provide matching 288-pin DDR5 RDIMM slots for each of the six sticks.

How are the six 64 GB sticks installed, and which population rule is most often missed?

Install one 64 GB RDIMM per channel following the motherboard's 2Rx4 population order; the common error is skipping the prescribed slot sequence for registered DIMMs.
