The issue I'm facing is that after overclocking the CPU to 4.8GHz and setting the voltage to around 1.250, when I switch to CPU-Z it displays a core voltage of .648, which doesn't match what I expect. I've followed many tutorials with precise settings but still can't get the CPU-Z to align with my BIOS voltage.

If the mainboard operates at the lowest core voltage when the CPU is idle or running at 800 MHz, then increasing the voltage only when under load makes sense. This aligns with typical Auto mode behavior; you might need to adjust the CPU multiplier to manual settings to manually control the voltage. Many users don’t find it necessary to raise core voltages beyond the standard level to achieve a noticeable performance boost, though success depends on managing heat and power usage.

If the mainboard is using the lowest core voltage when the CPU is idle or at 800 MHz, should I increase the voltage only when under load? This seems like normal behavior for Auto mode; you might need to adjust the CPU multiplier to manual so you can choose the voltage manually. Many people don’t bother raising core volts above the stock level just to get a few extra MHz and improve performance by 1-2 frames, but it’s not very effective given the heat and power demands. I changed the voltage to 1.3 volts in the BIOS and haven’t seen any changes in the CPU multiplier. Previously, I manually set the core voltage, but it only reads 0.6 volts at idle and 0.6 under load, yet the CPU runs at 4.8 GHz with noticeable differences. Now even before booting my CPU, the default readings are 0.3 volts at idle and 0.6 under load, which is confusing. I’m a bit frustrated because I followed the instructions carefully but still didn’t get results.
