Overclocking method preferrance

Hi people
I have recently purchased a 3570k and am just getting back into the swing of overclocking and I have a question.
It seems there are now 2 methods you can use in the bios - multiplier or turbo boost; so is there any difference in real world performance?
I notice that if I use the turbo method my vcore scales down nicely when idle which I like but will it give me any inferior performance in games etc to a multiplier overclock?

Any opinions on this?

I think turbo helps lower power consumption, that's all. The scaling down is C1E in the power options. It will be the same as multiplier overclock under load, so no performance difference. I just find it tricky to get the offset voltage and load line calibration right.

I recently came up against this with my 2700k. If you've got the time and patience to play around with vairous combinations of offset voltages/LLC levels/C states and all the other settings, then overclocking with offset is definately better. Having less voltage being pumped through your chip at idle can only be a good thing.

However, if you're just looking for a quick boost without pushing the edges of stability, just overclock in the normal manner. As long as your chip is downclocking at idle as it should - it's lifetime isn't going to be severly reduced.

That's what I thought but I can't see the benefit of your CPU downclocking at idle if the voltage doesn't do the same? You may as well run it at your chosen speed 24/7 if your going to do this, as its volts not speed that reduces your lifespan I thought?

I recently got the rig in my sig and have messed around with both mutli and turbo/offset with all C states turned on, currently i'm running with the offset using turbo to get 4.4ghz, according to cpu-z i'm using around about 1.044v idle and about 1.28v on load,

I'm still trying to get my head around the LLC, currently with the turbo/offset i have it on medium where as with the multi oc i had it on turbo, might also still aim to hit 4.5ghz but needing 1.3v or more to get it.

If your cooling is good and you can keep it temps down i don't see much of a big deal with keeping the volts up 1.25-1.3v isn't that high anyway and most people have been overclocking this way anyway, but on the flip side once you've found that you're stable with just a multi oc it shouldn't be a problem setting the correct settings to down volt when idle.

no thats not true, if you run a temp monitoring program you will see that your temps are low with fixed voltage and and C1E enabled at idle. in fact you will have similar temps at idle if you have C1E and offset enabled.

the only time the life span of your CPU will be degraded is if you combine high volts AND high temps.
