Purpose-built server kit

This 128GB kit targets administrators upgrading or populating the ASRock Rack W890D8-2L2T motherboard. It delivers four 32GB registered DDR5 modules with on-die ECC for data integrity in continuous workloads.

Build integration

The modules use the standard 288-pin DDR5 RDIMM form factor and operate at 1.10V, drawing power directly from the board’s memory slots. No heat spreaders are fitted, so airflow across the DIMM area must be provided by the chassis or CPU cooler.

Capacity and limits

The 2Rx8 organisation across four slots provides 128GB total at 6400MHz with CL52 latency, suited to virtualisation hosts and database nodes. Systems requiring more than four modules per channel or lower latency timings will need a different memory configuration.

Perguntas sobre este artigo

Does the CL52 latency limit throughput during sustained workloads?

CL52 is the rated CAS latency at 6400 MHz; actual sustained throughput depends on the memory controller and workload pattern.

How much heat and power does the 1.1 V kit draw when running all day?

Each module operates at 1.1 V DDR5 standard voltage; total power scales with all four 32 GB ranks under load.

Must the ASRock Rack W890D8-2L2T motherboard already be installed for this kit to work?

Yes, the kit is validated for the ASRock Rack W890D8-2L2T and requires that board's 288-pin DDR5 RDIMM slots.
