Hi, welcome to the overclocking world. I'm just starting out with my old unlocked AMD X2 555BE, currently running smoothly at 4 cores and 3.5ghz. I'm having issues with the fixed voltage setting—starting at 1.38, it's jumping wildly between 1.376 during idle and 1.424 under full load. The M.IIO 770 C45 motherboard is in place. Any advice would be greatly appreciated!

I don't have a strong opinion on the optimal CPU speed. But if you're okay with the current settings, try reducing the memory speed first—it might help as the multiplier increases. Good luck!

The cpu vcore is going to rise and fall. A better power supply will reduce these fluctuations. That said, you can attempt to improve stability by enabling LLC in the bios. Some older motherboards lack this option. If you're not seeing any crashes, don't worry too much.

Thanks for the update. Now I'm stable at 3.6ghz with 1.42 core voltage, reaching a max of 1.462. I already have an aftermarket cooler and haven't faced any temperature issues. Should I push it higher or are the voltages limiting performance? Also, since I clocked by changing the core multiplier instead of using the traditional bus method, should I also increase the CPU overclocking? And if so, do I need to adjust RAM speed manually? I have two 1333mhz DDR3 sticks.

I don't have a good idea of the optimal speed for running your CPU. But if you check the number, lowering the memory speed first might help, since it tends to increase as the multiplier goes up. Good luck!
