New motherboard voltage worry!

[Mene50]

Hi,

I recently fitted a new Gigabyte motherboard to my PC (2 days ago) and although so far its working nicely I am very worried about some voltage readings on my psu.

My specs
AMD Athlon II X4 620 CPU
Gigabyte 78LMT-USB3 Motherboard
8gb DDR3 Kingston ram
Windows 7 64bit Home Premium
570w PSU

I was running the software HWMonitor (by CPUID) and it shows the voltages and cpu temps.
its showing my +12v as 7.9v, my +5v as 2.8v, my +3.3v as 1.9v!!

If I load EasyTune6, on the HW Monitor tab, it shows my +3.3 as 3.320v and my +12 as 11.990-12.220v  which I assume are normal voltages.

My worry, which software is correct?

None of them.

If you want to read the voltages use the BIOS.
If you want real readings get a multimeter and start probing.

Software just pickups some readings from the chip that takes care of monitoring and that s all.
If the guys that make the software don t calibrate it for your specific motherboard you will see bogus info.

I see, then I'd better reboot and check the bios.
I'm sure the multimeter is the best idea but I don't have one and not being really knowledgeable about that sort of thing, I think its safer if I don't try.

Checking the bios now, thanks!

Voltmeter is the only true way to check on these voltages.

I am sure those sensor readings you are getting are incorrect as the PC would be very unstable with such poorly supplied rails.

Well I reset and went into the bios.

I put it on the PC Health page and watched it for a good 10 mins.

the voltages seemed rock steady with very tiny fluctuations, 3.32-3.34, 11.8-12.0

I guess HWMonitor is telling me lies, I'm upgrading my gpu tomorrow from a Radeon 4670 to a GTX 650 and the last thing I needed was a dodgy psu.

Thanks again for the help.

I just updated EasyTune 6 to the latest version and watched my voltages in that.

+12v and +3.3v seem very stable indeed, the only fluctuation is in vcore, its always (I mean every 2-3 secs) changing between 1.390v and 1.110v when the system is idling.

oddly enough when the system is busy or stressed the vcore voltage goes to 1.390v and is rock steady.   until the system is idling again and away it goes switching back for forth again.  odd

Not odd. It's a power saving feature. If you watch the cpu clock, the speed will dip t the same time as the cpu volts. Nothing to worry yaself about.

Thanks for that!
