There's a tab under overclocking in the bios u can just set the turbo mode to 4.0 /4.2 / 4.4 /and up
It's fully automatic.
Dont mess with the gpu settings. set your xmp on your ram to the setting it came with.
The I7 runs hotter because hyper-threading so just up it a little and test until u get the temp your comfortable with.
Without water cooling u will probably only increase a small amount like 2-4 tenth of a Ghz.
All the other settings u will just have to Google because they are not in the manual. Or use toms hardware guide at the top of forum.
I really recommend using standard xmp(for ram) and as rock turbo (for cpu only)-(not gpu)
