  • DDR5 4800 speed with PC5-38400 bandwidth rating
  • ECC registered design detects and corrects data errors
  • 1 V operating voltage reduces server power draw
  • Validated for ASUS RS720A-E12-RS12 dual-processor server

Capacity and form factor

This kit provides 192GB of DDR5 memory across six 32GB RDIMM modules. Each module is a 288-pin registered DIMM with ECC and a 1Rx4 organisation, designed for server motherboards that require registered error-correcting memory.

Who should buy this

The kit suits administrators upgrading an ASUS RS720A-E12-RS12 2U dual-processor server to its full 192GB capacity. Builders needing unbuffered UDIMMs, non-ECC memory, lower capacities, or modules for workstation and desktop platforms should select a different product.

Speed and latency

All six modules operate at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.1V. The registered buffer and ECC function are mandatory for the target server; systems that do not support registered ECC RDIMMs will not accept this kit.

Questions about this item

What does the 4800 MT/s speed mean once this memory is installed in the ASUS RS720A-E12-RS12 server?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated bandwidth when the server's memory controller is configured for that speed.

How does the ECC registered design affect data integrity and system compatibility?

ECC corrects single-bit errors and the registered buffer reduces electrical load on the memory controller, a requirement for the ASUS RS720A-E12-RS12 platform.

Will the 288-pin DDR5 RDIMM modules fit the memory slots in this 2U server?

Yes, the 288-pin DDR5 RDIMM form factor matches the DIMM slots on the ASUS RS720A-E12-RS12 motherboard for direct installation.
