ASRock WRX90 WS EVO 512GB DDR5 kit

This 512GB memory kit contains eight 64GB DDR5 4800 CL40 registered ECC RDIMM modules. It is built for the ASRock WRX90 WS EVO motherboard in server and workstation environments that require registered error-correcting memory. The kit suits IT professionals managing mission-critical workloads.

Registered ECC RDIMM modules at 1.1V

Each module is a 2Rx4 288-pin registered DIMM with on-die ECC operating at 1.10V. The registered buffer and error correction maintain data integrity under sustained load. No heat spreaders are included, so airflow in the chassis must handle thermal dissipation.

512GB total capacity across eight slots

The eight-module kit populates all eight DIMM slots for a combined 512GB. Builders needing fewer than eight modules or a different total capacity should select another kit.

Questions about this item

Do the 8 x 64 GB modules have heat spreaders that might need cleaning or replacement over time?

The kit uses bare modules without heat spreaders, so no spreader maintenance or replacement is required.

With CL40 latency and 4800 MT/s speed, will CAS latency be the first bottleneck during sustained workloads?

CL40 at 4800 MT/s sets the baseline access delay; under sustained load the registered buffer and ECC overhead typically become the limiting factors before raw latency.

Running all eight 1.1 V registered DIMMs continuously, how much heat and power should I expect?

Each module operates at 1.1 V; total power scales with all eight DIMMs active, and the registered design adds slight heat versus unbuffered modules, though no spreaders are fitted.
