Capacity and target system

This 128GB kit contains four 32GB DDR5 modules validated for the ASUS ProArt Z790-CREATOR WiFi motherboard. It is intended for workstation users who need large memory capacity for content creation or compute workloads.

Build and connector implications

Each module is a 288-pin UDIMM without a heat spreader and runs at 1.10V with CL40 timings. The unbuffered non-ECC design fits standard desktop DIMM slots, while the dual-rank 2Rx8 organisation helps density on four-slot boards.

Pre-order compatibility checks

Verify that your motherboard supports DDR5 4800 UDIMM memory and can populate all four slots at the rated speed. Confirm the BIOS version allows 128GB total capacity with 2Rx8 modules before purchasing.
