Dangerous voltage readings; inaccurate?

post #1 of 9
Thread Starter 
So I have been trying to get 4.8ghz stable on my i5 2500k, and while checking my temperatures and voltages during prime95 I noticed something very alarming, as you can see in the image. 338

Is this just an inaccurate reading? Prime95 continued without any errors or BSOD's during the course of these apparent fluctuations, which I am hoping means that they are simply false readings.

In case anyone can't see what is wrong, look at the min and max values for each voltage.

which voltage do you mean? VTT?

Well that, but also 12v, 3.3v, DRAMv, and VCC

do you have a multimeter?

Yeah but unfortunately I don't have the time to take the rig and test it right now. I was just wondering if anyone had any insight as to what could be going on here.

it may be wrong readings.. and look at yo temps..100+°C .. theres something stuck?! i also read recently that hwmonitor can lie with certain voltages but i cant find the thread.
the inet will tell you the right reading points for yo board i think

try aida64 or other software to find out if there are any differences

I can't imagine the computer still running with the voltages fluctuating that much, so hopefully it was just false readings, but I'll have to keep an eye on it.

when youhave time i can give you the voltage read points for the UD3H. I think perhaps the software is incorrect.

Software readings are always off, and i find hwmonitor is always way off, even cpu-z is way off. Best to take true voltage readings from voltage points on the motherboard.
For me cpu-z reads high and fluctuates up once in a while but when i compare to cpu voltage point with DMM on the mobo, its flat, reads lower and only fluctuates by 0.00x volts
