Core Voltage for x6 1055t @4ghz
Ive never done any overclocking ever so im really confused about this whole voltage thing. If im Ocing the cpu to 4ghz what should i set my voltage to and how do i know if the voltage is stable?
Just want to add some points to lowjack's reply.
Voltage settings really varies depending on individual CPU and the motherboard. Try running Prime95 without any overclock and run CPUID-HWMonitor or CPU-Z to check the CPU voltage at maximum load without overclock. Voltage setting in BIOS for this should be AUTO.
Then start doing overclocking step by step (not directly to 4.0GHz) and initially set voltage closest to what you found and see how to behaves with overclocking by running Prime95 for some hours at-least and monitoring system state with HWMonitor (especially the temperatures which should be below 62C I think; but lower is better). If system crashes then try increasing voltage step-by-step (in single units which your BIOS gives you minimum like my BIOS allows +-0.025v at single step). And as lowjack said: don't go above 1.55v.
What is the model of your motherboard ?
For example my CPU 1090T with GA-990FXA-UD3 is at 3.8GHz @ 1.40v (HWMonitor tells 1.41v) with CPU-NB at 2.4GHz @ 1.175v. It all depends on each CPU manufactured and motherboard.
