If you are wondering how to check the voltage of your CPU, read on. There are two ways to measure this- one is with a multimeter, and the other is using software that will do it for you. Let’s take a look at how each option works!
The first thing you need to do is determine the type of voltage measurement system your motherboard uses- either Vcore or VRM.
If it has an ATX power supply, it most likely uses Vcore; if not, it probably uses VRM (if it’s an older computer). So next up: grab that multimeter!
What Is Vcore?
Vcore is the voltage of V connectors on motherboards. Vcore is a voltage that comes from VCC_IN, and it is the core of your CPU. The CPU/GPU operates in this voltage, and this is where most people get confused. How do you differentiate Vcore and other voltages? How do you increase/decrease a value? How to see Vcore or other voltages are the things people often ask.
What Is VRM?
VRM stands for Voltage Regulator Module, and it works in conjunction with the motherboard’s BIOS to deliver power to all of the components. How VRM delivers voltage is through different resistors on PCBs, which are large-scale integrated circuits that control voltages inside your computer. How much power provides to CPU/GPU depends on the quality of your motherboard’s VRM.
If you want to have a stable overclocking experience, having a good VRM will help you get there without worrying about shorting out anything inside your PC or increase temperatures beyond the acceptable threshold.
How To Increase Vcore?
The easiest way to increase Vcore is by setting the Vcore value in BIOS. How much do you need? How much voltage can harm your CPU/GPU? How much voltage will improve performance? How to check these values is what you should know if you decide to change them.
You can either have a static or dynamic (dynamic load changes) vcore. Static means that no matter what happens, the amount of voltage will not change. Dynamic means that when there’s a load on the CPU, it increases voltage until the PC gets full throttle.
How To Decrease Vcore Or Other Voltages?
Don’t change voltages on any part (CPU core/RAM/NB) in BIOS unless you know what you’re doing. If you change anything, make sure to test stability after each change. Unfortunately, we cannot be held responsible for any damage.
How To Check CPU Voltage With Motherboard BIOS?
1. Find the jumper where you select the socket of your motherboard; it should be on pins 1,2 or 3 (check your motherboard manual for details)
2. Remove any material that might be blocking the socket, such as a plastic bag or clothes.
3. Turn off the computer and unplug it from the power outlet.
4. Move the jumper to pins 2-3 (for reading voltages) and then plug in the power cord of the multimeter into Pin 1 with the red lead wire leading to Pin 1; do not forget to connect the black lead wire to a metal part of your computer case too!
**if there are no jumpers, you will need to plug in the power cord of the multimeter into Pin 1 with the red lead wire leading to Pin 1, while another black lead wire is touching a metal part of your computer case.
5. Read any voltage readings on your multimeter display.
6. Unplug the power cord and move the jumper back to pins 1-2 (for enabling computer), then plug in the power cord again and turn on the computer; now, you can access BIOS settings.
How To Check CPU Voltage With Software?
1. Make sure your computer is connected via an internet connection (to access CPU-Z directly).
2. Download and install CPUZ software.
3. Ensure that the utility application you are using lists all of the voltage settings available in your system BIOS, such as Vcore = 1 .100 V Vdimm = 2.000 V
4. Compare these voltages with those supplied by your motherboard manufacturer; if there is any discrepancy between them, then look for another utility program or update the current one due to error!
How Can You Lower Your CPU Voltage Consumption?
1. Use a mild overclock setting without the need for extreme voltages, such as Vcore = 1 .150 V
2. Use a quality power supply unit (PSU).
3. Change the stock cooling fan with an after-market cooler that can lower your CPU height temperatures; this can decrease your voltage consumption too!
4. Only use one high-performance graphics card in your system. If you have two graphic cards, remove one graphic card to reduce overall heat/vibration/noise caused by computer case fans and airflow resistance inside your computer case. It helps you to lower CPU temperature & frequency rates too!
5. If none of those tips worked for lowering the voltage, then you could consider using a program to lower it, such as “HP Power Manager”! How much wattage your computer case fans use and how many of them are on/running inside your computer case will affect CPU temperature/frequency rates, so try to keep it cooler by lowering the voltage!
In conclusion, there are many reasons why you should measure the voltage of your CPU. But, first, it’s important to know how to do it so that you can be sure everything is running smoothly and efficiently on your PC.
How often have you had problems with a faulty power supply or poor quality cooling? These issues could all be solved by doing something as simple as checking your CPU voltage! We hope this article has helped clarify what an easy step measuring CPU voltage is with these steps.
