So recently I changed my cpu from a core i3 550 into a Xeon x3430. It booted into bios just fine and everything showed just fine except that the resolution was low. A simple restart fixed that. Installing CPU-Z, I see that the Vcore voltage is at 2.016 volts. That seems a little dangerous to me, I thought cpu’s ran at 0.8 -1.3 volts?? Is my Xeon gonna die if the voltage stays like that? I have a Phoenix bios that doesn’t let you change the voltage.

Considering the CPU isn't smoking/on fire, whatever is reporting that voltage must be wrong. 2V would kill it pretty quickly, and until it died the temps would be astronomically high.

I'd look at what other programs like HWinfo say if you really want to know what voltage it's running at, but considering temps don't look too bad I'd just put it down to a faulty sensor

Yea I know, but the Xeon is a quad-core whereas the i3 is only a dual core, which is why I switched. I’m just asking if running the cpu at that voltage is going to damage any components

That's way too high even for a 45nm. Many systems have a hard limit of 1.6V. and shut down at that setting. Are your temperatures high?
Those really are the 2 slowest CPUs on that platform. All the other Xeons have HT for 8 core performance. Even the i3 has it for 4 core. Did you enable that in BIOS for the i3? But I'm not sure what's causing your problem.
CPUZ doesn't always get Voltage right. Try HWInfo64 and see what you get there.

My temps are around 60-70 Celsius under load. Keep in mind that’s with a stock cooler. If there is a 1.6 volt hard limit then my system shouldn’t even be booting so I’m guessing that CPU-Z is just being inaccurate. But the reason I got the x3430 is because it has 4 physical cores unlike the i3. Yes I had hyper threading enabled I just wanted 4 physical cores.

Hwmonitor is also reporting 2.016volts, but seeing as how my PC hasn’t self destructed yet, I’d just say the voltage reading is inaccurate. Thank you for all your help though :D
