i7 4770K cpu input voltage question

[SamDe]

Hello

Today I noticed in my BIOS that my cpu has an input voltage of around +1.744 V.

To be honest I have no idea if this is bad or good but is seems a bit high to me. I'm not Overclocking.

Specs:

ASRock Z87 Extreme 4
I7-4770K @3.50 stock (3.90 turbo) (no OC)
Sapphire HD6870 (currently on Intel HD integradted graphics due to GPU errors atm)
Kingston HyperX 8GB (2 x 4GB) DDR3-1866 (KHX18C9T2K2/8X)
Kingston SSD 120G
2x extra HD's

Thanks!

That is about average. That is the voltage supplied by the Motherboard to the CPU essentially. The CPU's VRMs then regulates it again to run the CPU itself.

So the core voltage will be up to 1.2 on a stock processor with a Vin of somewhere around 1.7. The system can handle about a max of 1.9v on air cooling with a Vcore of 1.3. If you bump up to water cooling you can get away with a little more.

Thanks! So nothing to worry about?

If i went into OC, what lines should be the ones I should be worrying about/ keeping an eye on?

VCCin usually runs about 0.5v above core voltage when CPU is under load. When overclocking. I set VCCin to 1.9 which is usually good for up to 1.35 core voltage or so. At 1.3875 core, I needed 2.08.

1.7 is just fine

Ok thanks for the answers! +1
