Stable Overclock?

I am currently trying to overclock my 8350 on a m5a99fx pro MB. I have it set to 4.6Ghz @1.4 volts. I thought this was enough voltage, but when I run the prime95 stress test/ Overdrive stability test, my computer freezes after a few minutes. For anyone with a similar setup, what is your voltage/ speed?

 

*I'm cooling with the NH-D14

Just raise the voltage bit by bit. Every CPU is different. Some OC better than others with less voltage. Just keep your temps down. 

FX-8350 @ 4.8Ghz. 1.45V

Cooled by a Kraken X60. 

Stop using Prime 95 and get Aida64. Most FX-8350 CPUs will run 4.6GHz with between 1.400v and 1.464v stable.
