I'm fairly new to messing around with computers, I just installed a new Thermaltake tr2 700w psu and I noticed now that my cpu voltage is at 2.2v according to cpu -z. I'm not sure if it was like that before or not. Any advice would be appreciated.
Specs+a hd 5750 and the new psu: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en...

WOW, 2.2v is massive for stock clocks, what CPU are you using? what are the temps reported by CPU-Z?

Athlon ii x4 640, temp are nice and low. I heard that it could just be cpu-z misreading it.

Amd Overdrive is saying voltage is normal but core temps idling at 57c. And cpu-z is saying the opposite. I don't know what's right from wrong.

sometimes AOD doesn't report things correctly, especially if you have overclocking directly through the BIOS, AOD is designed to overclock through the program, if CoreTemp is saying 57C and 2.2vdc, then you need to reset the BIOS and hope that fixes it.

According to THIS page you are idling near max temperatures, could you have forgotten something when installing the CPU cooler? maybe the Thermal paste?

I have the stock cooler, this is an oem pc, I've done nothing to it other than installing a gpu and I just swapped psu. Cpu-z is saying temps around 20c but voltage at 2.2, amdo is saying temps at 57c but voltage at normal. I have a very basic motherboard with no overclocking and it doesn't Give me any cpu info such at voltage and temps.

it could be a hardware bug as you say it is an OEM motherboard, have you noticed any significant performance issues? install and run Fraps to get the FPS overlay and then play a game, if the frame rate is significantly lower in moments of heavy CPU demand like sprinting or driving a car, then there may be a problem, additionally since this is an OEM motherboard it might not handle the new GPU demand, is it a power GPU? meaning does it have the PCIe 6 pin or 8 pin power connectors directly from the PSU? or does it draw its power from the Motherboard?

I haven't really noticed any issues, I installed the gpu right after I bought the pc about 3 years ago. It's connected to the psu with a 6pin

you might be getting false reading from your OEM board, as i recall my eMachines had an ECS motherboard, and when i tried monitoring things it said my 5670 had 3GB of GDDR5 ram when the card only had 2GB

but regardless, i recommend being cautious with things at the time being, but i recommend a new motherboard soon.

if your CPU was at 2.2v it would have been fried in a matter of seconds so don't worry

indeed. Which is why i suggest a new Motherboard as this current board seems to be reporting false readings.
