Overclock 3770K with multi or turbo

Just wondering what most people favor. Do they overclock by just setting the turbo value for each core or if they use the boards multiplier. Also wondering which is better - fixed or offset cpu voltage.

Will be overclocking my sabertooth z77 / 3770k soon (just waiting for my PSU) and will go for a reasonable 4.2ghz to begin with.

I would like my cpu speed/voltage to drop as low as possible when I'm not pushing the PC. So I am thinking I will just let the cpu voltage and turbo on auto and up the multiplier to 42. Run IBT to check for stability and see what voltage is actually used. Then use a negative or positive offset on the cpu voltage depending on stability. Think LLC of 75% should be enough from what I have read to minimize vdroop. Not sure what effect this will have when system is idling though ?
 
What ever you do don't leave the voltage to auto, it uses twice as much as it actually needs, you should get away with about 1.2v at 4.2 ghz. Might need a little fine tuning though.
 
That's the reason you have an offset mode. Once you know what you cpu uses under load, a negative or positive offset in bios will adjust what voltage is used under idle/load. It is a perfectly viable alternative to using a fixed voltage and this also has the advantage of dropping your cpu voltage when system is idling. Where as a fixed voltage of 1.2 will still use 1.2 when system is idling.
