Do I change voltage to adaptive when done overclocking?

[KaaN10]

Hi.

Just wondering if I'm supposed to change the voltage to adaptive when I've found the right multiplier/voltage/temp?

Or does it stay on fixed?

Thanks.

up to you. Sometimes adaptive will spike too high so I guess many people would turn it off.

Adaptive or offset is definitely better for longevity and better overall temps since you're going to be in idle states a lot; it also helps prevent electromigration. If this is a system you're planning on keeping for over 2 years, I would recommend adaptive. Idling at maximum voltage is a bit silly because the temps and power usage will be higher than is necessary, and you're also causing unnecessary electromigration by having manual voltage - I've come to have a disdain for manual voltage because the temps creep up over time. There's no reason to idle at 1.28V or what have you, when IVB and Haswell can idle near 1V (IVB) or sub 1V (Haswell) and lower power consumption/temps.

Anyway, i'd say adaptive is the way to go. Consult your manual, but you normally have to put your boost vcore target in your settings, and Haswell's iVR will take care of the rest during idle states. You can also try offset voltage, but it is a LOT trickier. Generally speaking, adaptive voltage with asus motherboards is pretty straightforward and easy, hopefully that will be the case for you as well. If you try offset, plan on spending a couple of hours or more tinkering with it. Offset is a pain in the neck to dial in.

The only word of caution is that in many cases, offset or adaptive have the potential to have the proper boost vcore, but then will idle at a vcore which is too low. If that happens, you will BSOD. I've found this problem myself using offset, so be aware that you may have to play with it a bit - adaptive should be fairly easy to set up, though.

Running 1.28V adaptive will yield an AVX voltage boost up to 1.36 or 1.4V I think, which will probably throttle most cpus or even crash the computer (when running AVX2 enabled software).

Even if you run stock voltage it will reach around 1.2V running AVX. For me, default idle consumption was 78W (whole computer), if I set vcore manually to 1.2V the computer idled at 83W. 5W difference between 0.704V and 1.2V.

I've set mine to 1.32v adaptive 4.5GHz. I tested it with Aida64 and vcore will go pass 1.40v which makes the CPU throttle. However, i've checked with Aida monitor running in the background while playing Crysis3, or even FSX which is high Cpu demanding that the voltage never goes beyond 1.32v.

So the question is: what application will make the vcore exceed the adaptive setting besides the 100% load stress testers? I will keep an eye on this

I've always found adaptive to be less stable and FAR harder to properly test stability on.

I would leave it on hard-set value if you want/need 100% stability.
