Measure orange-battery positive pole



It was 1.961 Volts.
So +3.3V is 1.450+1.961=3.411Volts

Measure red-orange:



Thus +5V is 3.411+1.769=5.180 Volts!

Note:
This is not necessary if you have a high precision multimeter or an oscillator.
Both of them are expensive..

Left of CPU socket located some black chips known as MOSFETs.
Each of them has three pins.
The first is positive Vcore.
So put red probe on it warning your hand must be steady otherwise your mainboard will burn!



The black probe of multimeter we put on PC chassis for reference ground.
The value was 1.756V.

If we put the red probe on middle pin we measure the negative voltage.
The value was 0.012V.



Thus my Vcore is 1.756-0.012=1.744.

Tip:
If we cannot put probe on a MOSFET we can measure Vcore on coil.
Nodes are located on the back of mainboard.

Similarly we can measure Vdimm if we find the proper MOSFET around memory slots.
Of course on the back of mainboard like coil we can measure Vdimm too.



Tip:
You have to seek a bit to find the proper MOSFETs.
This photo shows my mainboard's chipset (gold heatsink) but the shown MOSFET does not give Vdd.



The MOSFET is here (it be shown with a blue tube)



White arrow shows a MOSFET where I measured Vcc_HT.
Note AGP slot is green.
