Sh0r_ty, am I reading right and seeing your LDT bus running at 1280MHz? The HTT can't go over 1GHz without leading to stability issues, you should have the LDT ratio down to 3.
Either way, a 2.7GHz Winchester on an Asus AV8 is nothing to frown at, if you've given it the max vcore possible there won't be much else you can do and you'd be lucky if you hit 2.8GHz. Your processor has probably capped or the motherboard is the obstacle in this case, not cooling.
