so i should
set it in the bios for turbo with core i72700k to auto or set it to bye all cores?
I have no idea what that means.
its not o.c i put it back at stock
and when i load optimized defaults in the bios its puts the blck/pcie to 103 and i have to change it to manual and put in 100
Once again....what? You are correct to keep the BCLK at 100. Going over that overclocks the whole system including things that can be damaged by overclocking them. Keep it at 100.
