ASRock WRX90 EVO 512GB DDR5 kit

This 512GB kit contains eight 64GB DDR5 5600 registered ECC RDIMMs validated for the ASRock WRX90 WS EVO motherboard. It targets workstation and server builders who need maximum memory capacity with error correction for mission-critical workloads.

Registered ECC modules

Each 2Rx4 module runs at 1.10V with CL46 latency and includes on-die ECC for data integrity. The registered buffer reduces electrical load on the memory controller, allowing all eight slots to be populated without signal degradation.

DDR5 5600 bandwidth ceiling

The PC5-44800 interface caps peak throughput at the rated speed, so workloads that scale beyond this bandwidth cannot be accelerated by faster modules without a platform change. The 288-pin RDIMM form factor also prevents use in consumer UDIMM-only boards.

Questions about this item

Will the eight 64 GB modules need any maintenance or replacement once installed?

DDR5 ECC RDIMM modules have no moving parts and no user-serviceable components, so they do not require periodic maintenance or scheduled replacement under normal server operation.

What limit appears first when the 512 GB kit runs at 5600 MT/s continuously?

The registered design and 2Rx4 organisation shift the first bottleneck to the memory controller's sustained bandwidth ceiling rather than the modules themselves.

How much heat and power do the 1.1 V sticks produce in an all-day workload?

Each 64 GB module operates at 1.1 V without a heat spreader, so total kit power scales with the eight ranks and the motherboard's VRM efficiency handles the resulting thermals.
