AMD FX 6300 overclock question.

lukeskywalkerbachman · Jun 1, 2016

I have overclocked my cpu to 4.3GHz and it runs stable after an hour of prime 95. The question that I have is are these voltages safe? What should be the max safe voltage that I use if I were to ever go further. I heard 1.5V is the max from a video on youtube and that you should try to stay away from that. Also my cooler is a hyper 212 evo.
4.3GHz
1.4V CPU
1.23V NB/CPU
My motherboard is an M5A97-R2.0

I always try to stay at 1.5v or less with AMD CPUs like that. 1.5V is the AMD recommended max for vcore. But you can take it higher at your own risk if you need to be stable with a higher multiplier setting.

-With amd cpus, you will fry the board before the cpu. You are limited to what the board can deliver to the cpu.

-Look at the bios monitoring page The page with the temps. See what the actual voltage is not what it's set to.

It's normal for a board to be set to 1.40volts and it's 1.37volts actual. That means you have 0.03volts of v-droop. So there is a 0.03 voltage drop. You don't want the v-droop to be too high or you risk frying the board. 0.05volts would be a big v-droop where you are starting to risk the board.

Increase the set voltage so the actual voltage is over 1.40volts. 1.45volts is likely ok for that cpu. How close you can get to that depends alot on the board. Watch your v-droop.

The 6 core should be more forgiving with 2 less cores than the 8 core fx. So you should be able to go higher than if you had a 8 core with both actual voltage and speed.

The max safe voltage is 1.55 from AMD.

Need4speed is correct, the 6 cores can handle voltage better, but not frequency as they are a lower quality unit than the 8 cores. I've ran my old 6300 4.9Ghz @ 1.65 Vcore without too much trouble. Very hard to keep the chip cool though and VRM's will have to be actively cooled at this voltage of course.

AMD recommends up to 1.3 voltage on the CPU North core when overclocking. My 6300 needed it to stay stable, especially because I overclocked using bus speed as opposed to multiplier. Bus speed increases CPU northbridge speed. CPU northbridge speed increases L2 Cache performance. L2 Cache performance increases single core performance

.

Right now I run an 8320 5.0Ghz @ 1.58 Volts. Temps are very hard to keep down with an 8 core. VRM's are actively cooled again.

Thank you so much for helping me!
