Low core voltage

[G3n3ralpotato--]

I have just built my new pc and I noticed it was running slow in windows and I saw task manager say it was running at .53 ghz then I went into the bios to look and my cpu core voltage is at .680V how do I fix this or is this a faulty motherboard.

The cpu adjusts the frequency of cores automatically depending on how much load is. If a core has nothing to do, the frequency is lowered to the minimum or the core is even turned off completely to save power.  If the frequency is very low, the voltage can also be lowered a lot. 

 

Use a program like HWInfo64 - https://www.hwinfo.com/download/ -  to look at the sensors and see all the core frequencies and the voltages. While you have HWInfo64 open, start a cpu heavy application, for example try OCCT's cpu test : https://www.ocbase.com/occt/personal and when the benchmark runs you should see the frequencies of cores go up and so should the voltages on each core go higher. 

 

Also look at the temperature sensors while the benchmark runs... if the cpu reports that it runs at 100 degrees celsius then it could be an issue with your cpu cooler / water cooler not cooling your cpu properly. (but keep in mind cpu benchmarks are designed to run processors at 100% for a long time so it's normal for the cpu to be hotter than normal)

 

If the voltages and frequencies stay low during the benchmark, then it could be a bug of some sort, it's not necessarily a faulty motherboard. You could try updating the bios to the latest version and also you could try updating the chipset drivers to the latest version published on amd.com or intel.com

It was the motherboard I switched it and now it’s showing correct voltage
