CPU throttling on low temps
CPU throttling on low temps
CPU: AMD FX 8120 @ 3.1GHz (stock)
MOBO: Asus M5A78L-M/USB3
I disabled all power-saving options, such as Cool n Quite and Turbo Core.
I attempted overclocking initially and reached 4.0GHz without any issues, but noticed that core voltage and clock speeds decreased to 0.9v and 1.4GHz when running Prime95!
These changes didn’t affect my CPU temperatures, which stayed below 40°C (Corsair H80i).
When this issue arose, I reduced clock speeds and voltages while monitoring closely.
The same problem persisted even at stock settings, which is unusual.
I believe the overheating isn’t due to my MOSFETs, as the data sheet states it can handle up to 175°C.
Here’s a graph showing my voltage and clock speed over time:
My Windows settings are set to Minimum: 100% and Maximum: 100%.
How can I resolve this?
Thanks.
The VRMs on that board are too weak and may lead to throttling on a 125w CPU even with default settings. This issue often occurs with the 760g and many 970 boards using 3+1 and 4+1 VRM configurations. Adding heatsinks to the VRMs and ensuring proper airflow can assist, but the best solution remains upgrading the motherboard.

Sure thing. I'm sure it's the same board again for the reasons mentioned earlier. My nephew has the same board and an 8320. We were able to avoid throttling while playing by just undervolting and keeping speed alone, but it still throttles when running at full power.
