Hello guys. I am running a 4770k on an asus b85m-g non overclocked. I just upgraded my computer case, and when i put everything back together and started the pc, I got the "CPU over voltage error". I checked in the BIOS and in the first screen the CPU voltage was showing as normal. But when i checked in the advanced section of the BIOS, under the Monitor tab i see that my CPU input voltage is around 3.5V. I also checked through CPUID(CPU-z) and also in HWInfo. I dont see anything wrong in these programs. Also the CPU temperatures are very good ~30C. I am not sure if this is an actual problem or a problematic report from BIOS side. I tried to reset it to default, and reset the CMOS with the jumper as well. I even tried to set the VCCIN manually to 1.8 but still the same issue. Any ideas?

If your computer's processor (CPU) is actually just sitting on a battery with three point five volts, it will die right away. Just update your BIOS settings so it shows the real amount of power instead of lying to you about how much electricity is being used.

There is no chance the CPU runs at 3.5 volts because it will burn right away. Please refresh your BIOS settings. The computer thinks the voltage is wrong when it's actually fine. I tried updating to the newest version on their site, but the error stays the same.

The CPU needs power from about 1.9 to 1.95 volts. It usually runs at 1.9 volts. When I run "HW Info", what does it show for this voltage? Can you take a picture of the number showing 3.5v?

Vellinious, your computer's CPU voltage should never be higher than 1.95 volts at high power settings. Usually, it sits right around 1.9 volts. What does the Hardware Info app show for this voltage? Can you take a picture of the voltage reading that shows 3.5 volts on the screen? Here is the BIOS tab image where the voltage looks above normal: https://ibb.co/mS0bta And here is the CPUID screenshot: https://ibb.co/gXEQmv Also here is the HWInfo picture: https://ibb.co/nHcxYa

andreasch386 : Vellinious : The CPU voltage shouldn't go higher than 1.95 volts on the high end. Usually, it sits around 1.9 volts. What does HW Info show for that number? Can you take a picture of the voltage reading showing 3.5 volts? This is the image from the monitor tab in BIOS where the voltage looks too high and says it's above normal https://ibb.co/mS0bta And this is the image from CPUID: https://ibb.co/gXEQmv A picture from HWInfo as well: https://ibb.co/nHcxYa HW Info has sensors. Please screenshot that part. Everything looks normal just like you said in the others. The board wouldn't last long at 3.5v input voltage and neither would the CPU. It's probably an error in the BIOS. Have you contacted ASUS customer service?

I uploaded it here as well. https://imgur.com/a/Uw3hv I am afraid that RMA is not an option since it was bought 2-3 years ago. The funny part is that the pc has been working fine for the last 24 hours or so, with very good temperatures.

There's something bad wrong there.
