Server-grade DDR5 capacity

This module delivers 128GB of DDR5 memory in a single registered DIMM. It operates at 5600MHz with a CAS latency of 46 and runs at 1.1V. The 2Rx4 organisation and ECC support target data-integrity workloads on compatible server platforms.

Registered DIMM slot requirements

The 288-pin RDIMM form factor fits server boards wired for DDR5 registered memory. The on-board register buffers address and command signals, reducing electrical load on the memory controller when multiple modules are populated. ECC circuitry corrects single-bit errors without involving the operating system.

Suited for high-density server upgrades

This module suits administrators expanding memory in qualified DDR5 servers that accept 128GB registered ECC DIMMs. It is not for desktop PCs, workstations lacking registered-DIMM support, or systems requiring unbuffered or non-ECC memory.

Questions about this item

How does the 46 CAS latency affect sustained throughput on this DDR5 5600 module?

The CL46 timing is the JEDEC standard for DDR5 5600; under continuous load the memory controller will run at this latency, so sustained bandwidth is limited by the 5600 MT/s data rate rather than tighter timings.

What thermal or power behaviour should be expected when this 1.1 V ECC RDIMM runs 24/7 in a server?

At the rated 1.1 V the module draws typical DDR5 RDIMM power; the registered buffer adds slight overhead, but no extra cooling beyond standard server airflow is required for continuous operation.

Which server platforms can accept this 288-pin 2Rx4 registered DIMM?

Any system with DDR5 RDIMM slots that supports 5600 MT/s registered memory and 2Rx4 organisation; the module is not compatible with desktop or workstation boards that require unbuffered UDIMMs.
