If you are using high speed rams you have to raise imc?
I know this question its bit generic, but would like others settings.
Mine at 4.4Ghz needs 1.28V (normal + 0.03v offset), 1.65 PLL and the other settings on Auto. All energy savings are enabled. Temps under 75°C (intel burning test v2.54 very high 10 passes, 32°C ambient).
I also use offset to overclock and also have all power saving features enabled. On the "3d power" screen, I have the first setting on "exm perf" or whatever the highest is called. The second setting I have on "fast". The vcore LLC is set to "high". I also decreased PLL to 1.65v like you did at some point, and it changes nothing I can see.
Those are all settings I touched. Setting LLC to High or Turbo seems to be the only one that is important. After this, I just increase multiplier and offset. This works for up to 1.44v vcore for me and I'm scared to look at anything higher.
If your CPU is like mine, you will have to do more than just IBT to be sure that it's stable. Passing prime95 blend for 20 hours needed a good bit more voltage than IBT. After it had passed prime95, the PC seemed perfectly stable on first look, but there were still suspicious program crashes and WHEA warnings showing up in the event viewer. I checked for WHEA warnings at the end of each day and needed to increase offset in 0.005v steps over the course of a few days.
Overall, it ended up being about +0.05v difference between passing IBT and where it eventually ended up. Looking at my notes, it went from passing IBT at 1.22v to 1.265v for the final vcore.
About going from that to higher speeds, the moment it starts to pick up with voltage required for my CPU, it needs about +0.05v for every 100mhz step up. That rule works from vcore of about 1.2v to 1.35v. When it goes towards 1.4v, it wants 0.06v and 0.07v for additional 100mhz steps.
If your CPU behaves exactly like mine, it would look like this if you really are completely stable at your current settings:
4.4 ghz -- +0.03 offset (1.28v)
4.5 ghz -- +0.08 offset (1.33v)
4.6 ghz -- +0.14 offset (1.39v)
4.7 ghz -- +0.21 offset (1.46v (that's scary))
