Capacity and purpose

This 512GB kit contains eight 64GB DDR5 RDIMM modules running at 4800MHz with CL40 latency and ECC registration. It is built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard and targets professionals who need maximum registered memory capacity for compute-intensive workloads.

Upgrade path

The kit replaces smaller DDR5 RDIMM sets or mixed-capacity configurations that limit total addressable memory on the WRX90E platform. The jump is worth it when applications demand the full 512GB ceiling and registered ECC stability is required for data integrity.

Installation notes

Modules use the standard 288-pin DDR5 RDIMM form factor at 1.1V and install in the motherboard's DIMM slots following the board's population rules. Common issues include failing to seat all eight modules evenly, ignoring the required slot order, or skipping a BIOS update that enables full-capacity recognition.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on the ASUS Pro WS WRX90E SAGE SE?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the motherboard's registered DIMM slots.

Do I need to populate all eight slots or follow a specific channel order when installing the 8x64GB kit?

Install one module per channel across the eight channels; the motherboard manual shows the exact slot sequence for full 512GB population.

Will the Samsung, Micron or Hynix DRAM chips on these modules require any firmware updates or special cooling over time?

No firmware updates are needed for the DRAM; the modules run at 1.10V without heat spreaders, so ensure adequate chassis airflow for long-term stability.
