128 GB DDR5 4800 ECC registered server memory for ASUS RS720-E11-RS24U 2U dual-socket systems
This 128GB DDR5 RDIMM is built for the ASUS RS720-E11-RS24U server platform. It targets administrators who need registered ECC memory for mission-critical workloads. The single-module design fills one 288-pin slot with high-density capacity.
The module uses a 4Rx4 organisation running at DDR5 4800 with CL40 latency. That rank structure must match the motherboard memory map; systems expecting a different rank layout will not post. Verify the server documentation before installation.
Registered buffering and on-die ECC correct errors continuously during extended compute jobs. The 1.10V operating voltage keeps thermal output steady across all twelve-eight gigabytes under prolonged utilisation. Modules are stress tested under load before shipping.

The module operates at DDR5 4800 with CL40 latency, delivering the rated data rate when the server's memory controller runs at that speed.
The 288-pin RDIMM uses a register to buffer address and command signals, while ECC provides single-bit error correction and multi-bit detection on every transfer.
It is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits the regular DIMM slots of that 2U dual-socket chassis.
