    Any HW voltage experts here?


    I have noticed some readings on HWMonitor for my newest build. Maybe I haven't noticed it before but are these readings correct? The BIOS shows the 12 and 5 volt readings fine so I assume this is normal or a software "thing" do you know if this looks okay?

    First let me say that software is one of the worst ways to read things like voltages, the only accurate way is to use a voltmeter. Different programs can report different readings. That said it can be any of the following,

    bios
    sensor chip
    the program itself

    Are all those readings reported in the bios? If so do they look OK? If so then it can still be a bios/sensor chip reporting issue (which you can't do anything about, unless the board manufacturer has a bios update that fixes it), or the program doesn't have the necessary bits in it to read the specific sensor chip on the motherboard.

    P.S. If it helps any HWMonitor doesn't even read the 12V on mine at all. Neither does Asus' own Asus Probe (and both will report the 3.3V reading at around ~1.15V). The only program I have used that reads mine properly is Everest

    As I said in the 1st post, the BIOS shows the 12 and 5V fine.

    I can't even find the voltage "section" in Everest.

    I'm sure everything is fine. It's a new P55 motherboard. Maybe it's a new sensor chip and the software has not caught up yet.

    For all I know these are correct. I am not an electronics wizard. I don't even know why there is a "-12" and "-5 and have no idea what the "+5 VCCH" is. The BIOS only shows the 12V and 5V. They are fine according to the BIOS.

    It's under Computer - Sensor.

    Also with Everest if you haven't found it yet, it has full Sidebar support in & and Vista (look in File-Preferences) depending on whether your version is recent enough (anything from 4.xx and up I believe). If you have an older version you can give the latest beta versions a test from here,

    I though there might more comprehensive values like HW Monitor but I found them. They look fine but I have a "trial version" of Everest but it's a 5.xxx beta. I really like SIW better. I was wondering if maybe someone could look at their HW Monitor values and see if mine are about the same. I think i will get a voltage meter.

    What does your SIW show for voltages ?

    SIW and HWMonitor must grab the use the same sensor and give all information. Everest looks like it uses a different sensor or reads it different. Here is SIW and HWMonitor side by side.

    I think the sensor on this new motherboard may be faulty. I have never seen the +12 like this before. I may need a multi-meter.

    The voltages come up (except the -5) during load. I don't now if this matters.

    Load

    Don't trust any software when you try to get information about current voltage.
    I have top model of the strong Tagan PSU and for example for years SpeedFan shows me this voltages (in attach)

    Fortunatelly I have multimeter and I can by self manually check this, and you know what? Voltages are always stable and OK in my case.

    My advice - buy simple multimeter or voltage-meter and check voltage by self, I'm sure it will be OK (you have good PSU model)

    Yep,

    Also nate42ndif any of those 12V readings that are showing in all those screen shots of yours were accurate, your computer either wouldn't boot (too low) or something would be fried (16V peak, I don't think so).
