If you are using manual vcore in BIOS, yes. I do not like using manual since it feeds a high constant voltage. I am using offset with add turbo but it is tricky to get stable since it may crash at idle if there are not enough volts. Currently I am testing my 4700MHz settings with vcore 1.080 @ 1600 idle and 1.368 (Prime95 blend) and AIDA64 (1.392) @ 4700MHz. Temps are 62 degrees and below.
Normally the idle crashes happen when you are using offset and a high setting for LLC - if you use regular (and a higher offset) it should help.
