Okay so i have my CPU maxed at what it will do under 1.3V and no i will not go above that because i fried an old one at just 1.365V but would a offset voltage or fixed be better with all the C-states enabled?

I'd say go with whatever you like.

Or whatever you are comfortable with.

I heard some time ago that offset is more accurate tongue.gif

If you do not use offset, your voltage won't be lowered with the C-states or EIST, only your frequency will be lowered..

yes but does it harm the cpu to be operating with that extra voltage at just 1.2GHz?

Yes, higher voltages reduce the lifetime of the processor by accelerating electromigration. May not be significant enough depending on how long you plan to keep the processor, but why not just use offset?
post #7 of 8
also offset just makes sense because why would you want to pump the volts when they are not needed? its more efficient and better for your cpu thumb.gif plus volts=heat so your cpu will run cooler when your not using its full power

I really don't see how you could "fry" that CPU with 1.36V unless you turned off Thermal protection and used a piece of wood for cooling. for sure something else was going on.

In any case, IMO offset OC is the best of everything: low voltage/low speed idle, peak voltage load when you need it. You need to play with LLC/offset settings to find the best mix for stability.

I've been running mine at 3.6 with offset OC lately, peak VCore 1.368. Haven't had time to tune for a higher offset OC yet but I'm sure it would be a matter of spending the time to get the balance right.

Fixed VCore OC will be easier to make stable, I can do 5.0 pretty easy that way, but I feel much better with offset.
