    CPU Voltages: Is there something odd in this...


    Is there something odd here?
    Voltage CPU CORE 1.072 V MEMORY CONTROLLER 3.008 V +5V 5.027 V +12V 4.480 V -12V -8.576 V -5V -8.576 V +5V HIGH THRESHOLD 4.973 V CMOS BATTERY 3.232 V
    Some of the right hand figures differ substantially from those on the left. Do they tell me anything? It all looks a bit odd.

    What software did you use to get those readings? Can you post the full screen shot of that?

    As a guess, that looks like the volts from your PSU ... and those all look normal.

    The +12V should be 12V +/- 5%. But, if the computer runs, those voltages are not right. The computer could not run if the 12V rail was 4.480.

    The details were taken from Speccy, and are part of the section related to the motherboard, I have now attached a notepad file of the whole screen.

    My computer is not the youngest and problems arose recently, but are now solved, but the stats here seemed a little strange, so I wanted to know if what I saw was a warning sign.

    The only thing I see wrong is the +12V. However, I am reasonably sure it is just a false reading. At that voltage the computer wouldn't run at all. So, it seems you just have an incorrect meeting or a faulty sensor on the motherboard. Neither one has anything to do with how your computer runs.

    No problem. You are quite welcome.

    Sorry to some back, but does a sensor on a nearly seven year old system point even vaguely to a need to replace?

    No. Actually, I don't believe you can. It is more likely that the software can't read it correctly.

    Your PC wouldn't run as others have said if your voltages were that far out. It seems you may have a problem with the motherboard sensors or software. You could try different monitoring software. I use CPU ID Hardware Monitor http://www.cpuid.com/softwares/hwmonitor.html
