adjust fx8320 speed from 3.5ghz to 4ghz
adjust fx8320 speed from 3.5ghz to 4ghz
I kept my setup like this and now I understand something odd. When the CPU is idle or loading slowly, the clock speed fluctuates between 1600 mhz and 4300 mhz. This is my first experience with overclocking, so I’m unsure if it’s normal or not (I didn’t adjust the voltage, so everything is using the stock setting automatically).
Here’s the image.
Completely normal. Intel has EIST, speedstep, and other CPU features that let the CPU “relax” when there’s little activity. Windows also contributes to this behavior.
The user can set minimum and maximum processor states (read speed) if those features are available with the CPU. AMD offers similar options. Even if the user switches to High performance mode, they can still adjust advanced settings I’ve made. There’s no reason for a car’s RPMs to stay fixed at 7000RPM when it’s only going 15mph. The same goes for CPUs—there’s no point in wasting power when it’s not needed.
I turned off all power-saving options in the BIOS and my Windows is running in High performance mode… so you’re telling me I can’t change that, right?
did you disable cool and quiet? that will significantly reduce the idle speed to maintain a cooler cpu and conserve energy. while adjusting the overclock settings, i kept it off. after finishing the tuning, i turned it back on to ensure the cpu stays cool during low usage phases. in this way, the cpu won’t throttle based on socket temperature as suggested earlier. the best way to gauge how close you are to throttling is by using amd overdrive to check the "thermal margin." when this reaches zero, throttling will start. if the value is negative, it indicates overheating. since amd typically reads internal cpu temperatures through a sensor under the cpu rather than directly from the CPU itself, most programs don’t display accurate cpu temps. this makes amd overdrive the only reliable method to assess the actual die temperature relative to its maximum. limiting the cpu die temperature to 20-15°C from its max is reasonable, but you should aim to keep it below 10°C from the maximum to avoid issues.

the settings you mentioned were adjusted for better efficiency. Cool and quiet was turned off during tuning to maintain cooler CPU operation and conserve power. After finishing the tuning, it was reactivated to ensure the CPU stays cool during light usage phases. Based on this, the system should not throttle based on socket temperature as previously thought. The only accurate way to assess throttling risk is by using AMD Overdrive to check the thermal margin. When this reaches zero, throttling will occur. A negative value indicates overheating. Since AMD typically measures CPU temperatures indirectly via a sensor under the CPU rather than directly reading internal temps, the 55°C maximum is set as a guideline. It’s important not to drop below 10°C from the maximum reading, as single-digit values are too close to the limit.
Here’s what I changed:
Cool and quiet : Always Off
C1E: Disabled
SVM: Disabled
Core c 6 state: Enabled
HPC mode: Disabled
Apm Master Mode: Auto
During stress testing, the thermal margin was around 29.25°C, which is within the expected range. I’m curious about the reasoning behind keeping power-saving features active—Max explained that Core 6 exists to manage power efficiently. During low-power tasks, the PC adjusts accordingly without needing full performance. High speed or overclocking doesn’t improve results; it just puts extra strain on the engine, similar to pressing the pedal in 2nd gear at 30 mph.
