Aight, so, I tinkered with C-States and whatnot .. Seems Asus boards wont let you disable Turbo completely. They have their own "Turbo" mode as well, and its either Intel's, or Asus's. No other way about it. So, I reset everything to default, re-did my boot order appropriately, and fired up the "4-Way optimization" deal. Set it to target 4.4Ghz, with the "Balanced" setting in windows power profiles selected .... For the first time, the system booted @ 4.4Ghz, with less than 1.250v. After the program did all its magic, I had a semi-stable 4.4Ghz clock. I then changed the power profile to High Performance, and attempted to boot ... no go. Slowly bumped voltage till I could get into windows .. Got to the desktop @ 1.280v. Ran a single test .. BSOD. Back into bios .. Set vCore to 1.304v, and VCCIN to 1.860v .... heres what I ended up with ..
TL;DR= C-States have almost no bearing. The windows power options, do. 30 minutes of pretty heavy and different workloads, stable as can be. Might just sit here and be happy with it, lol.
