For my 24/7 overclock I run everything stock (including VTT) expect my Vcore at 1.25v and Vdroop disabled. This is 99% stable at 4ghz. I got one error in Prime blend after an hour, but for what I do in everyday use, game, encode movies etc, its stable enough. If I ever crash doing anything Ill raise the Vcore two notches.
Ram is at 2:8 with stock timings, Bclk 191.
Finally got my last two orders placed. Ordered the pump last night and the fans\controller 10min ago. Down to playing a waiting game.
EDIT:
Holy crap, my USPS tracking says my rad should be here

Not sure if they left a slip in my mail box or not, too lazy to go to our mailbox (1/2mi), my dad should be home with the mail in a matter of minutes.
