Capacity and platform match

This 64 GB kit contains four 16 GB DDR5 UDIMM modules built for the ASUS ProArt Z790-CREATOR WiFi motherboard. It targets workstation users who need maximum supported memory capacity for content creation, rendering or virtualization workloads. The modules are non-ECC and unbuffered, matching the board’s consumer-class memory controller. No heat spreader is fitted, so clearance is minimal.

DDR5 4800 practical limits

The kit runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10 V. This is the baseline JEDEC speed for DDR5, so the memory controller will not require manual tuning to reach the rated frequency. Bandwidth and latency are fixed at this specification; higher data rates or tighter timings are not supported by this module. The 288-pin form factor fits only DDR5 slots.

Pre-order checklist

Confirm that your motherboard is the exact ASUS ProArt Z790-CREATOR WiFi model, as compatibility is validated for this board only. Verify that all four DIMM slots are free and that the BIOS is updated to a version supporting 64 GB of non-ECC UDIMM memory. The kit uses 1Rx8 Samsung, Micron or Hynix ICs; mixed-rank populations are not covered by this validation.

Questions about this item

Should I pick the 4x16GB kit or a different capacity for the ASUS ProArt Z790-CREATOR WiFi?

The 64GB (4x16GB) kit fills all four DIMM slots on the board and runs at DDR5 4800 with CL40 latency.

What does the 4800 MT/s rating deliver once installed in the ProArt Z790-CREATOR WiFi?

The modules operate at DDR5 4800 (PC5-38400) with 1.10V and CL40 timing, giving the rated bandwidth and latency out of the box.

Is the 288-pin DDR5 UDIMM interface the limiting factor for speed on this motherboard?

The kit uses standard 288-pin DDR5 UDIMM slots; the motherboard's memory controller and BIOS determine the maximum supported data rate.
