How to get an accurate voltage reading?

post #1 of 13
Thread Starter 
I've tried various programs: Throttlestop 2.97, CPU-Z, Easy Tune 6, and others, and each reads a different voltage coming from my processor.

When I set the voltage to a low amount, CPU-Z reads that exact amount I've set. When I set the voltage higher (say, 1.35v), CPU-Z reads the wrong voltage (it reads 1.06 or something instead), and Throttlestop reads something closer to what I've set.

So what I'm wondering is... is there any program out there that can actually read processor core voltage properly?

I'm never sure if my core voltage is running at the specified amount in my BIOS, because every program I run says a different voltage.

I've always trusted HWMonitor and CPU-Z, but if those are both reporting different voltages then I'm at a loss to help.

The only issue I have (with HWMonitor) is it rounds out the voltage at two decimals, whereas CPU-Z rounds out to three. This makes it look different though they're actually the same (or so I would assume).

I'd be interested in reading what others have to say on this topic as well.

never ever ever ever ever ever trust software to tell you your voltage, EVER!

But but but I'm too sissy to go find my motherboard readout points and buy a digital multimeter.....

The only way to get an accurate reading is with a DMM. No software will be 100% accurate and it can not be trusted. I have tried to instill this into some members here and some people just refuse to listen

I agree. You want accurate, get a good meter

I am getting fustrated from my UD9.
It gives false data on almost all the volts.
1.49v at vtt is actually 1.47v, 1.55v at vcore is actually 1.52v, 1.3v at qpi pll is actually 1.33v and so on.

I'm looking for just approximate (since multiple programs are giving me issues). One reads my voltages as 0.1v more than the CPUID voltage readings. But CPUID reads my voltages about as my motherboard is set (I set it to 1.315v and CPUID reads that), but I have power saving settings enabled and when things downclock, CPUID still reads 1.315v... whereas another program reads the voltage dropping to 1.05v when power saving is enabled (but it reads 1.38v when things are stressed 100%).

Anyways, I guess I'll have to do some reading into volt meters. O_O;

The main thing for me is this: I want to make sure the voltage I'm setting in BIOS isn't being overshot by too much. I also want to see if I can get the power saving options to kick in and reduce the voltage, even though I have the voltage set to a certain amount. Wish I had a volt meter right now lol.

i set 1.35vcore in bios and get 1.41V real
+225mv Vtt gives me 1.49-1.51V almost .1V off
vdimm is just as bad, 1.65 in bios gives me 1.72, again almost .1V off.
do yourself a favor and get a multimeter.
