CPU Overclocking, Vcore MAX myths and truth

[aigomorla]

guys i thought i should add.

Like gillbot said, one should always double check the real voltage with bios read voltages.

A lot of people dont like premium boards, however the trend now in premium boards is to put voltage points where u can take a multi meter and get the voltage directly off the board and not via bios like so:

I still am the side saying never fully trust bios unless u've already pre calibrated it to a real multi meter.

What unit is Everest displaying CPU current (not Wattage) in? because my q6600 when maxed is showing around 80.06A which I know isn't Amps and Can't be milliamps is it deciAmps or WTF? CPU 22.69 A that's Nominal overclocked to 3.6 ghx cpu multiplier 8 on a Ga EP45-UD3P

This is a sticky for PSU's but it still applies: http://forums.anandtech.com/showthread.php?t=257485

Moral is, NEVER trust software readings unless you can verify them with actual measured readings.

Rather than debate, just experiment and see!

This article solved all my load line calibration questions. Hope it helps you guys.

Great info!! While that is good news, I wouldn't apply that thought to ALL motherboards and sockets though as they can use different components and have different tolerances.

For the sake of completeness, I repeated the test with LLC disabled, the results were essentially the same though the VCORE dropped under load instead of going up. No spikes.

This summed it up in a nut-shell, and also sorta validates/confirms the utility of monitoring Vcc with CPUZ because the o-scope showed us exactly what CPU-Z showed us all along.

(no significant spikes occur when unloading but LLC does prevent Vdroop when loading)

A device that dissipates 105W of energy and has a voltage in the 1.3V range would have around 80 Amps of current going through it, yes.
