Hi, I have a stuttering problem with my i7-13700kf.
When I play games my games run smooth but randomly the start to lag a lot. CPU usage drops from 50% to 10%.
My motherboard is ASUS PRIME Z790-P D4 and I have 4 sticks on DDR4 3200Mhz ram
Update your bios, and make sure you correctly installed your cooling solution.
