Hi everyone.

Any help with setting up the GPU to run @ x16.   

ROG strix z790 -E wifi ii

i7 14700k

4070 super

32 GB ddr5 corsair

m2 2.1 - not occupied hence no sharing

m2 2.2 - Samsung 990 .

bios setup to PEG,  x16.

freshly installed win 11 pro

After clearing cmos for brief moment the cpu-z shows 

current link speed 16, GT/s

but after 1-2 sec than goes to :

current link speed - 2.5 GT/s

Any advice please

SOLVED !

My mistake, all alright. When I run something which use GPU resources the speed link go up to full capacity of my card.
