Hello !
I'm completely new to overclocking and don't have much experience with PC hardware.
I looked at my specifications and see that my FX-8320 is running at 3.5 ghz with 4 cores (that seems confusing since it has 8 cores?)
I thought I'd try changing the CPU settings from the stock speed to turbo at 4.0, but I learned not to use the turbo core at all.
Here are my details:
CPU: AMD FX-8320 Black Edition
Motherboard: Gigabyte 990FXA-UD3 (rev.4.0)
Cooling: Cooler Master Hyper 212 EVO
Temperatures from the CPU HW Monitor (in Celsius) when nothing is running:
AMD FX-8320, Package: Value 35, Min 31, Max 43
And the other one (Gigabyte tech): Value 43, Min 42, Max 43
System: Value 43, Min 42, Max 43
CPU: Value 50, Min 48, Max 52
TMPIN2: Value 33, Min 30, Max 45
First of all, is it safe to change it to 4.0 ghz on this motherboard?
If yes... I would really appreciate it if someone could explain the process in the simplest and safest way. What should I disable in UEFI, what changes are needed, etc.
Thanks!

Adjusting the FX 8320 to 4Ghz should be manageable. Proper configuration in the BIOS is essential, and achieving the optimal overclock requires fine-tuning both multiplier and FSB settings. I’ll share several guides to help you set up your system correctly. Feel free to ask if you need more details.

Yes, that board works well for overclocking. Disable Turbo Mode in BIOS and raise the CPU clock multiplier to 20. Save and restart. The clock speed will remain at 4GHz unless you enable Cool and Quiet to reduce it when idle.

For 4ghz the multiplier should be 20 rather than 40 since AMD employs a starting frequency of 200mhz.

Adjusting the FX 8320 to 4Ghz should be manageable. For optimal results, several BIOS settings need proper configuration, and it's recommended to use both multiplier and FSB for the best overclock. I'll share some guides to help you set up your system correctly. If you have any queries, don't hesitate to ask.

For a 4ghz setup you should aim for a multiplier of 20 rather than 40, since AMD's base frequency is 200mhz. Setting it to 40 would be an 8Ghz overclock and wouldn't work. I recommend starting with a multiplier of 19 and adjusting the bus from 200 to 211 using the provided guides for voltages and NB settings.
