Sorry for delayed response
Use ASUS Turbo V and you'll see the default offset, IIRC it's 272. I have dabbled with it occasionally, so my memory is hazing on which way tweak results on what kinda skew. If you try a small change (ie 268 vs 278), you should be able to see affect.
Be aware using this skewing also means over temperature protection on CPU may not at correct temp, due to the skewing. So if cooling fails you could be looking at CPU going to excessive real temp, resulting in damage, etc.
