I tried my first shot at OC and managed to get my FX 6300 running smoothly at a stable 4.3.
CPUz, on the other hand, is behaving unpredictably. It's currently stuck around 1404.69 MHz, but it can jump up to about 3000 MHz and spike as high as 4300 MHz. Is this typical?

It's about reducing the clock speed to conserve energy. Make sure a power-saving option is active in your BIOS. This feature won't slow down when you need more performance, such as during gaming. You can disable it in BIOS if preferred. Still, it works well. Great overclocking!

Turn off cool and quiet in your bios to reduce core frequency when idle, which helps save power but may affect overclock stability and cause throttling under load. If it’s already off, please let me know. Other settings should also be disabled—here’s a guide if you’d like more details.

Ensure your bios is set to cool and quiet mode; this reduces core frequency during idle to conserve power, which may affect overclock stability and cause throttling under load. If it's already off, please confirm. Other settings should also be disabled—please refer to a guide if needed.

If your overclock isn't stable enough to handle cooling and quiet/speedstep, I wouldn't consider it stable.

Edgerunner :
Turn off cool and quiet in your bios, it will lower core frequency when at idle to save power, which can affect the stability of an overclock and even cause cores to throttle under load. If it's already off, let me know. There are other settings that should be disabled as well; I'll link a guide if you're interested.
"Always Disable" or "Disable by CPU"???
I think either works, but always disabling seems more recommended. I'm not entirely sure about the difference. I usually use always disable.

If your overclock isn't stable enough to handle cool and quiet/speedstep, I wouldn't consider it stable. Most people don't use cool and quiet or turbo cores for overclocking AMD and FX CPUs. Every guide I've read advises turning them off.
