Auto Voltage and Why it's Evil

Gigabyte Z77 Overclocking Guide

The Perils of Auto Voltage

Remember how we've been brow-beating you about the importance of having control over your system, and how AUTO is just the worst setting for CPU vCore known to man? We took our 4.6GHz @ 1.20v stable overclock from the previous page and solely adjusted the vCore from 1.2v to AUTO.

Look at how unchanging our voltage was throughout the preceding pages. Now look at how it is when just sitting at idle. 0.984v, 1.164v and 1.294v. Just doing nothing.

The one on the right is the CPUz from the moment we hit the OCCT go button. 1.404v. Exactly the same setting everywhere as was flawless at a manual 1.2v. Auto somehow believes we need 1.4v to achieve the same thing. This is a) above Intel recommended specifications b) an absolute heat bomb.

See how the graph climbed to the sky the moment OCCT was engaged. So horrific was the amount of voltage it used, that we hit the 80°C threshold in 20 seconds. TWENTY SECONDS to break the 80°C limit. On an overclock that was otherwise utterly stable forever on the settings we slowly worked towards.

Hopefully that's enough to make you never touch AUTO voltage ever again. You, your wallet and your hardware will thank you for it.

do you mean the windows 7 '4 spinning balls that turns into the windows logo' thing or the icon where your name is?

4 spinning balls thing=
type 'system configuration'
click 'boot' tab at top
tick the box marked 'no GUI boot'

if you ever want it back, simply untick.

as for the user log in bit.

delete other users and passwords.

there is a work around but i cant remember it off the top of my head as its very late, so just use google. as i remember its in regedit and its something like 'user control password'. anyway dont mess in regedit until you know EXACTLY what to change.Quote
