speccy is showing that 12V rail is giving below 9v(8.810V to be precise) to motherboard..... :shock:
should i change my local PSU or its just false reading..? :-?
also the proccy core voltage is fluctuating a lot.... its keep on changing its reading from 1.1V to 1.296V......
i just want my CPU components safe.... :|

here are the readings of speccy
3.3V - 3.024v
5V- 4.536V
VIN5- 0.752
VIN6- 0.938V
Memory- 1.296V
CPU- 1.272V

cpuZ result

Hardware monitor Winbond W83627DHG
Voltage 0 1.14 Volts [0x8F] (CPU VCORE)
Voltage 1 1.30 Volts [0xA2] (VIN1)
Voltage 2 3.02 Volts [0xBD] (+3.3V)
Voltage 3 4.54 Volts [0xBD] (+5V)
Voltage 4 8.87 Volts [0x9F] (+12V)
Voltage 5 0.75 Volts [0x5E] (VIN5)
Voltage 6 0.97 Volts [0x79] (VIN6)
Temperature 0 44°C (111°F) [0x2C] (SYSTIN)
Temperature 1 38°C (100°F) [0x4C] (CPUTIN)
Temperature 2 50°C (121°F) [0x63] (AUXTIN)
Fan 1 1493 RPM [0x71] (CPUFANIN0)
Fan 2 2813 RPM [0x1E] (AUXFANIN0)

any idea anyone....?

software HW monitoring tools are not 100% accurate to measure volt and temps - if your pc is working Ok then don't worry too much - try a better software app like HWinfo/HWmonitor.

The cpu volt fluctuates because of cpu power saving features which is completely normal ;-)

Check your PC.. If everything is working sweet and fine than it might be due to the Power saving features and suggested by topgear. :)

What's the reading in the BIOS?

i did mention in my first post "local psu"......

what abou t12v rail....? isnt the voltage too low or it is also energy saving....?

First we need to know whether your PC is working all fine or not ?

You can always crosscheck the readings with the hardware monitor under your BIOS. Or you can use hardware monitor by the motherboard manufacturer, I guess most of the manufacturers provide such tool.

working fine....
but still its better to take caution instead of getting roasted components.. :wink:

nope ... that's just a wrong reading by the software app you are using - I've seen this kind of issue before ;-)

bios also has voltage and temp monitoring feature ( use mobo manual to locate it ) and see the +12v rail voltage there - should not be lower than 11.65v
