How to measure voltage on an NF7-S v2?


1) Ok, I know I need a multimeter. Will this one do?

2) Once I get it how do I use it/where do I stick it?

Right now the BIOS is set to 1.8v, CPU-Z says 1.76-1.792 idle and 1.74-1.76 under full load. Flux of under 0.03 doesn't seem bad but I want to know what the real voltage is. I don't trust CPU-z that much. Right now I'm at 2.39ghz (11x217.4) @ 1.8v 43C full load, 32C idle.

At the bottom of this page, there is a pic w/ the "two" spots to check it from. However, ONLY USE THE SOLDERED POINT IN THE LOWER RIGHT CORNER OF THE PIC! W/ the other point there is a high risk of shorting the board out by the current, I guess, jumping over from somewhere. Many a boards have been fried using the point at the upper, left of the pic (one of mine).

Yeah I saw that pic after a search on google. When I go to test i stick both the Red and the Black probey thingys on solder right?

No, the red lead goes on the solder point and the black lead goes to any ground point. You do know that this is to find the chipset voltage and not the core voltage, right?

Someone said I needed a multimeter to check my vcore. As of right now I don't know the following:

1) If they knew what they were talking about.

2) Where to stick it.

3) What a ground point is.

I'm a visual learner so please bare with me.

Its quite alright.

1. They did know what they were talking about. You can check your Vcore with a multimeter im just not sure where the point is on the mobo. However... I find that the mobo displays accurate voltages and the only time I use a multimeter is to find the chipset voltage which isnt displayed.

2. I have no idea?

3. Basically touch the negative probe of the multimeter to any metal part of your case or your powersupply. You need to have a complete circuit to measure the voltage and putting both probes on the same point wouldnt make a full circuit.

That DMM will work.
You can check the vcore at the mosfets just to the left of the socket.
There are four legs on each mosfet than you can measure. One side has three legs. The other side has one long leg that is the width of the mosfet. Test them all and you will find one leg that gives you a reading close to what you set vcore to in bios. That's the one.
I stick one of the DMM probes in a bare metal hole in my steel case so that it hangs there by itself. That way the ground is taken care of and I only have to worry about one probe for measuring.
Don't touch more than one thing on your motherboard at once or you'll cause a short and it will die. For example, if you touch two of those little mosfet legs at once, even for a split second, your mb will be dead.
MBM5 shows my NF7's vcore undervolting and fluctuating, but measuring at the mosfets shows that it actually overvolts by .03V and does not fluctuate at all.
While measuring those mosfets you'll also find an accurate reading for your 12V rail.
