Voltage reading

Hello,

wich reading should I trust, the one from PC Probe II or those from SpeedFan and OCCT (this two have the same results)

PC Proble II's 12v: goes from 12.16 (idle) to 11.80 (while testing with OCCT)

or

SpeedFan/OCCT's 12v: goes from 12.8 (idle) to 12.42 (while testing with OCCT)

All have some results at vcore, +3.3v and +5v.

  1. If I were to put my faith in any software voltage reading it would be the software that was provided with the motherboard.
  2. Why not test with a multi-meter to confirm ?

  3. I dont have one, and for that price I could buy almost 50 kg of rice :P
  4. (1) Agree with delluser1. Check bios reading - This would/should be close to idle value. Some Bios give reading, some just show "OK". Check MB websit for software. For Gibabyte MB, easytune6 has a "health" page", Asus should have a similar program for monitoring PC Health.

    (2) try CPUID's HWMonitor, propably give you a 3rd value and you can flip a coin (jokeing of coarse).

    (3) On JackNaylorPE comment and your reply. Jack also gave you very good response. 12.8 V is above the established spec (12.6V) and should be checked. On the value of a digital VOM, They can be invaluable and have many uses other than just for a computer. In the home - Check an AC outlet, verify continuity, check batteries and many other electrical systems. For the car - Find out if that car battery is dying, or the alternator is not putout enough voltage to proerly charge the battery, track down a open circuit (be it a fuse, lamp, or wireing problem). You can check power adaptors (bricks) for proper voltage and if you need to verify polarity at the plug tip. These are just a FEW of the uses that may offset that 50 Kgms of rice.

    In bios 12v is about 12,08. I wii try CPUID's HWMonitor. Asus Probe II comes with motherboard.

    They don't. :)
  6. Use a Voltmeter. PSU testers only frovide a miniumal load and areonly good to use with a new/old PSU before installing. Once installed use a voltmeter as you can measure both Idle and with a full load.

    Any one of the DVMs you referenced would be fine.
