1.5 TB DDR5 ECC RDIMM kit

This kit provides 1.5 TB of DDR5 memory in a matched set of twelve 128 GB modules. Each module is a 288-pin registered DIMM with ECC and a 4Rx4 organisation. Rated at 4800 MT/s (PC5-38400) with CL40 latency, it runs at 1.1 V. The kit is built for the ASUS RS720Q-E11-RS8U 2U4N high-density server platform.

Who this suits and who it does not

IT teams expanding the ASUS RS720Q-E11-RS8U to its full memory capacity will find a validated, single-SKU solution here. Buyers who need a different capacity, a lower latency bin, or memory for another server platform should select a kit qualified for that specific system.

1.5 TB total capacity in twelve modules

The 1.5 TB figure is the decisive spec; it represents the maximum supported memory for the target 2U4N node. If your deployment requires less memory or a different module count, a smaller kit avoids unused slots and unnecessary cost.

Questions about this item

Will the 12 modules need individual replacement as they age?

All 12 modules are covered by the manufacturer lifetime replacement warranty, so any single DIMM that fails can be exchanged without replacing the full kit.

What limits sustained throughput on this 4800 MT/s kit?

The DDR5 4800 speed rating and CL40 latency set the bandwidth ceiling; the memory controller cannot push data faster than the PC5-38400 specification allows.

How much heat and power will 1.5 TB at 1.1 V draw in a 2U chassis?

Each 128 GB RDIMM runs at 1.1 V with no heat spreader, so total power scales with the 12 modules and airflow must handle the combined thermal load.
