    Default Normal -12 voltage on GA-EP45-UD3P?

    I was looking at the voltages for the board on SpeedFan, and the -12 voltage read something like -16V. Is this normal? It doesn't look normal...

    Thanks,
    - Eli

    of course its NOT right haha.... evne my -12V says -16.64 V :S
    U cant rely on SF to tell u voltages, better use the BIOS or another more reliable source.

    Everest Ultimate will show you proper voltages. Free Trail Beta's are available here >>>

    You will find voltages in the "Motherboard, Sensor" section, but the free version will limit your available Viewing options. I see since I grabbed a beta to test, the trial wont show you 12V but you can surely google one that will......

    Here is a paid version Screenshot



    Trial >>>



    Hwmonitor, PC Wizard, and Speedfan always seem to have very OFF voltages. But as said above software is not so great at getting them correct. But I have used Everest Ultimate for years and always find it to be very close if not spot on with voltmeters.

    EasyTune 6 will show you proper amounts, and your PC Health Section of your BIOS

    Thanks; I will check out EasyTune, looks like it lets me set my CPU fan speed. Does this override BIOS SMART fan controls, even if I have it enabled. Maybe I can test that Xigmatek fan and see what happens. I think it does come with a molex adapter, but I don't know if using that adapter will eliminate the BIOS fan speed control. I'll check out the BIOS section, too, like you both said, and see what it looks like.

    No, that works with Smart fan control.

    Ya, using that 4 pin adapter will make it run full speed always and any BIOS setting will not be used.

    If those are true readings you do, indeed, have a problem. You could try using PCWizard PC Wizard 2008 - Free software downloads and reviews - CNET Download.com to confirm. I would be trying another power supply ASAP before something else dies from lack of proper power.

    Is that reading from the latest Everest? I have never seen everest get things wrong, but then again that is a new board so if you are using a OLD everest it very well could

    Thx for the reply.

    The Voltage seems to be ok in Easy Tune 6 = 12.112v

    My PSU is a Corsair TX650W... Tested on another pc and it is ok

    I tried to replace the videocard... Same freezes

    Tested the memory 8 Hours memtest ...OK

    Tested the Dard Drive WD diagnostics ...ok

    I gues I'll start a New post but i think the Mobo is the one with the problem here :(
