Overclock and voltage increase failure AMD FX 8350

Problem: I was able to Run this rig with a 4.7GHz OC at 1.435v, 58C under load, for a few months. Now I cant even raise the voltage by itself (no multiplier change) without having the overclock fail. Nor can I raise the multiplier by itself to 4.2GHz (no voltage change) without having the overclock fail. Goes without saying my OC fails if I raise both voltage and multiplier. The rig runs just fine at default settings.... Thanks for the help.

so your computer runs fine at normal specs right?

and everything was running fine before while you oc'd and there was no additional components added before right? no changes. strange.

Correct. Vexing.

Can I ask what you did within your BIOS? like how you oc'd after you crashed?

and this is just a possibility, Maybe your CPU is not getting enough POWER, that one of your railings went bad since it can run at stock and not at OC.

After the crashes started I did tests with small overclocks with no success. (NOTE: I would always turn off the extra cool n quite type features before any overclock.) Raising just the multiplier to an overclock of 4.2GHz with no voltage change - No success. Raising just the voltage to 1.45 with no overclock - No success. And many other combinations of voltage/multiplier.

Its a single 12v line. Maybe its having a hard time handling higher voltage or inrush from the cpu. Want to rule out all other things before having to buy a 1000w PSU. You would think 775w @ 65 amps would be enough lol.
