I solved the problem, thanks to the answer below. It was indeed the VRM heating up over 80 °C and it throttled CPU. CPU was not heating up, but motherboard made it look like it was so that it could throttle it. The solution was to cool down VRM. It could be solved through a couple ways:
- Apply heatsinks to MOSFET VRM if your board does not have them already.

- Provide better airflow through your computer case, which can be achieved by:
- Cleaning your case and your fans
- Better cable management
- Smarter case customization
- More fans if really needed (usually unnecessary, better placement is more important)
- Some case chassis have places to add fans on the side, if not, you can get creative
- Buy a new part:
- New case
- Better fan(s)
- BETTER MOTHERBOARD!
- Additionally, you can make it so that the CPU fan blows over VRM. Cannot guarantee it'll work, because CPU fan will be exhausting hot air from CPU anyways, so it might even worsen. I didn't try, so just to let you know you might try it.
I had a old CPU fan, so I just installed it on the side of the case chassis, and it is blowing directly towards VRM. It is not exhaust but intake. Dropped my VRM temperatures by 10-20 °C. Downside to this is that now there is more noise coming while playing. It is not a big problem though because it is auto-adjusting its speed if there is no pin left out, if there is one, you still can do it via a program called SpeedFan. I plugged the CPU fan to System fan pins on the motherboard because there were no other pins. One is left out which is PWM pin. It doesn't auto adjust but I set it to 0% from SpeedFan while it is not necessary to use.
CPU dropping its frequency down to 1800 MHz.
What do I know about it?
- Seems to occur when the CPU reaches 50 °C. I am not certain if the temperature is the cause.
- When it happens, the temperature jumps to 206 °C and the frequency drops to 1800 MHz.
- Only happens while playing games.(so far)
- It is not related to my CPU being overclocked because it happens if it is not, as well.
- The only solution I've discovered so far is restarting the computer.
Please watch the following 15 seconds video that I captured from CPUID HWMonitor, it might prove to be useful to understand what's happening.
CPU: AMD FX-6100 Motherboard: MSI 760GM-P23 GPU: NVIDIA GeForce GTX 1060 3GB
- It occurs the most frequently while I'm playing Tom Clancy's Ghost Recon® Wildlands.
- I've used CPUID HWMonitor to monitor the temperatures. I am not very certain if the program is accurate.
Important: I know there is something called throttling, CPU or motherboard does it to protect itself from harm, but 50 °C seems to be a safe temperature. I know other people using the same program as I have see temperatures higher than 80 °C.
What are the possible causes for it to happen like this? How can I fix it? Also, any knowledge regarding the matter is appreciated, even if it does not solve the problem directly.
