Do we like C1E Enhanced Halt State for Sandy overclocking?

    Just wondered. Increases my vcore, watts, and temps some, esp. at idle, but it looks like I need it to stay stable at 4.7ghz (possibly higher)

    4.6ghz seems stable with C1E on, but some of the other C-state stuff disabled.

    We haven't had an OC'ing thread in a long while. After my computer speeds got up so high with the stock settings, I pretty much stopped overclocking.

    Holy shit, we're 4.6 ghz now? :eek:

    Getting closer and closer to that singularity point.

    What's the deal with the "halt state" overclocking? I guess I could Google it, but I'd rather you just give me the gist of it. Is it a BIOS exploit or something?

    In the past, you generally wanted all your voltages locked down, the less variance the better insofar as achieving stability at higher clocks.

    These days, the cpu's are instructed to conserve power (amps & volts) til it's needed. In some cases this included an intentional drop in vcore as the cpu was stressed-- the dreaded "vdroop". Now with Sandy and Ivy Bridge you can let the voltages vary more, with a good board you can compensate for vdroop, turnoff and on some of these instructions (C-states, e.g.)

    C1E seems to be the main one. Disabling it caused the volts and temps up, in exchange for some extra stability (Not enough, apparently, as I'm back at 4.6 for now.)(This could come back into play as I try the last couple tweaks)

    Thanks for explaining that. I'm still using C2duo and a board from '07. Maybe it's time for a new machine.

    I haven't built a new machine in years but decided to do it again to get my 11 year old interested in more than just playing games. I've bought an Asus Maximus V Extreme board and it's an amazing thing just to look at. But, I had to RMA it so looking at it is the only thing I've been able to do so far. The more things change the more they stay the same I guess.
