128 GB DDR5 ECC RDIMM kit

This 128 GB kit contains two 64 GB DDR5 4800 registered DIMMs built for the ASUS RS720QA-E12-RS8U high-density 2U4N rack server. It targets IT teams that need validated ECC memory for mission-critical workloads in that specific platform.

288-pin registered modules for dense server chassis

Each module is a 2Rx4 288-pin RDIMM operating at 1.10 V, designed to populate the server’s memory slots without extra cooling hardware. The registered buffer and on-die ECC free the memory controller from parity overhead, leaving more bandwidth for virtualization and database tasks.

CL40 latency at sustained 4800 MT/s throughput

Rated at PC5-38400 with CAS latency 40, the kit maintains its rated speed under continuous load thanks to major-brand Samsung, Micron or Hynix ICs that are stress-tested before shipment. The combination of registered signalling and ECC correction keeps error rates low during extended compute runs.

Perguntas sobre este artigo

Will the CL40 latency limit throughput when the server runs heavy workloads continuously?

CL40 is the rated CAS latency for these DDR5 4800 modules; sustained heavy workloads will operate at this timing.

How much heat do two 64 GB registered DIMMs produce at 1.1 V during all-day operation?

Each module runs at 1.10 V without a heat spreader; registered DDR5 DIMMs of this density typically stay within normal server thermal limits.

Does the ASUS RS720QA-E12-RS8U motherboard need a specific BIOS revision to recognise this 128 GB kit?

The kit is built for the ASUS RS720QA-E12-RS8U 2U4N rack server; consult the motherboard manual for any required BIOS version.
