I'll break out my DMM and measure under prime95, if that's good enough for testing..
Thanks


EDIT: OK, in the bios, no overclock, with CPU volts set to AUTO, it flickers between 1.088 - 1.096 in the bios, of course, this is at idle.

In Win 7, no overclocking, with prime 95 running, CPZ shows a max of 1.144

I have to locate my DMM and see what it shows as the real volts.
At stock voltage the VCore is off just about as much as it is in most of the reviews.

At any rate, at stock settings, there's probably no danger of over volting the CPU, but it's probably juicing the CPU too much even at stock settings .
Still, their engineers should have caught this problem

Yup the problem gets bigger and bigger the higher your volts are.

I thought I was running around ~1.51V from reading the reviews when my CPU-Z showed 1.48V under load but god was I suprised to find it ran at 1.58V instead tongue.gif

Well, if CPUz shows my i5-3570k at stock runs at 1.144 under load, even if the actual volts are off by let's say .08, then real world she's running at 1.224, so it's well below most overclock voltages.

Still, not a good thing. I'll wait for a bios update if I plan to overclock this CPU. Hopefully, there will be a bios update that fixes this. I'll report back my DMM readings once I locate my DMM that is...

thanks..

Getting the Z77 OC Formula tomorrow, will measure the VCore on that one aswell just for comparison.

Dear customer,



Please find attached comment and picture from my colleagues in Taiwan

Dear Rick,



This customer reports that the vCore in the bios is very different from what he measures.

He sent a link with the picture where he measures these values, and I don’t know if this is the correct location.

Also you can see what the BIOS value is, what voltage is found by the software, and what he measured with his 3 different multi meters.
Quote:
Dear Peter:



I did the test, but vcore voltage always under the value which I fixed.

Also the location from his picture is not relate to vcore, so he must got the wrong voltage

You can tell him to measure “VT1” next to the word “Z77 EXTREME4” .(Refer the picture)

Thank!

And this is the attached picture:

There is one pin there, not sure where I'm supposed to ground it on :l

If that is correct then I have been off by a very long shot lol.

PRIME:
CPU-Z: 1.480V
DMM: 1.499V from that VT1

IBT
CPU-Z: 1.504-1.520V
DMM: 1.533V

For those curious, I just grounded it in a screw hole.

EDIT: I have to admit, I'm a bit cautious to as if this is real or not, it is coming from AsRock themselves afterall, I wonder what those 2 pins next to the CPU socket really are because they sure look like the VCore reading aswell as it adjusts accordingly...

Speculating much? tongue.gif

I'm kind of perplexed as to why you'd measure the voltage so far away from the 8 pin. Seems like you'd want to be directly in between the source and the chip frown.gif

Exactly why I'm doubting why it is measured from there according to AsRock, could be just some node where the motherboard sensors take the reading from aswell?

I have no idea though, I've kinda novice at this, but I understand enough about circuits and all to understand that you'd need to measure it IN the loop, but whatever :-D

Me neither tongue.gif

But all the points around the CPU socket give pretty much all the voltage readings about memory and CPU voltages atleast so I would assume the VCore reading is correct aswell.
I guess we can wait for some fancy engineer to give his thought on the subject tongue.gif
