Capacity and platform fit

This kit provides 128GB of DDR5 memory across four 32GB UDIMM modules. It is built for the ASUS ROG Strix Z890-F Gaming WiFi motherboard and targets builders who need high-density RAM for demanding workloads on that specific platform.

Standard limits and signal load

The modules run at DDR5 5600 with CL46 timing at 1.10V using the PC5-44800 standard. Four dual-rank 2Rx8 sticks increase the electrical load on the memory controller, so stability at the rated speed depends on motherboard topology and BIOS support for four populated slots.

Physical build and daily handling

These modules ship without heat spreaders, exposing the bare PCB for a low-profile fit in tight CPU cooler clearances. The 288-pin DDR5 keying prevents mis-insertion, and the unbuffered non-ECC design keeps installation straightforward for standard desktop use.

Questions about this item

Should I choose the 128GB kit or a smaller capacity for my ASUS ROG Strix Z890-F Gaming WiFi?

This kit provides 128GB in four 32GB modules, filling all four UDIMM slots on the Z890 board for maximum supported capacity.

What does the DDR5 5600 speed mean for actual system performance?

The modules run at 5600 MT/s with CL46 latency at the standard 1.1V, delivering the JEDEC base data rate for DDR5 on this platform.

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

The 288-pin DDR5 UDIMM form factor is the standard desktop interface; the kit operates at the rated 5600 MT/s without requiring overclocking.
