Yes, if you experience hangs or BSOD then increasing turbo usually stops that.
currently running and testing with prime95 blend:]
Just a note : Prime doesn't help if you are trying to find out if you are stable at idle. Tho usually if you are unstable at idle then you won't be able to boot correctly, when that happens(and increasing vcore does not help) then you have found how low you are able to go. I would then bump up the offset volts by two levels(say it doesn't boot at -0.200, then just make it -.0190) and say you are good.
If you are unable to change the bios to revert what you did(because the system freeze or whatever.) Then you will have to clear the CMOS, which will change the BIOS settings back to "normal" like you never overclocked it or anything.(If you have saved profiles then they will still be there to use.)
didnt know that theres alot of things to do when i use offset mode. its kinda fun though!
I would have to agree that overclocking in general is somewhat fun. I would assume that this feeling is similar to what a person who likes to work on cars feel when tinkering with his car.
