I have my AMD A10-6800K Overclocked. All I did was increased my Max Voltage to 2.0V and increased the Multiplier to 43.0 and the Bus to 103 in my BIOS and I havent had any issues with FiveM running. I also have my RAM overclocked from 1600mhz to 1922mhz and I got better performance out of FiveM and GTA than i did at the base speeds on both my CPU and my RAM. My CPU Runs at 4.4ghz with my overclock and a Base CPU speed of 4.1ghz before overclock.
Overclocking will not cause any issues or file related issues if the clock is stable.
I haven’t touched an AMD cpu since my FX 3200+ back in the day… But I find it really hard to believe you’re using 2v on your cpu, that seems wildly excessively even if you were doing benches with liquid nitrogen. lol
