cpu phase control on/off? when overclocking

[Momenaut]

I still have no idea what a phase is but should I have this setting on or off when I'm overclocking? I read somewhere that it turns off cpu phases when they're not in use but it was dangerous to use when overclocking because you push more voltage through a phase when you're overclocked. Is this true? And are there any other potentially dangerous settings I should know about when I'm overclocking? (besides obvious voltage settings)

a phase is fundamentally another source of power to consume for the cpu. the more you have, the cleaner your power will be.

 

that's really over-simplifying it, but that gets the general point across.

Alright, but is it a dangerous setting to use if I'm overclocking?

[knightslugger]

no. Why would it be? That's not how electricity works... You're not adding voltage.

well it was my understanding that when it turns off the phase it puts the increased load onto less phases pushing them past what they're capable of and frying things.

just turn it on. It will use all power phases under high power draw anyway.

 

CPU phase control is used to shut off phases under very low loads to keep the VRM efficiency higher. that's it.
