overclocking voltages

[SoloRaptonic]

i am currently running an amd fx 4300 quad core overclocked from 3.8Gh to 4.3Gh. i have attempted to go further but if i up the multiplier or the FSB, i crash as soon as i start prime95. if i up the voltage, my system does not post. it simply reboots and idles until i shut it down and clear the CMOS. i have tried nearly quite a few different voltages all ending with the same result. i've seen others with this processor overclock up to 5Gh and i just feel there is so much more potential. if anyone has any suggestions, please let me know. if u need system specs, also let me know. thank you

my G3258 cant go past 4.0 ghz @ 1.3v even tho the avg oc for them is 4.6ghz
just unlucky with the chip i guess

It's a matter of luck. All chips are different. Some can hit 5Ghz, some can barely reach 4.5Ghz or in this case, 4.2Ghz.

i understand that it all really comes down to the silicone lottery, but my question still stands on why my system doesnt post whenever i change the voltage
