AMD FX-8320 Overclocking Help

[A Random Shrub]

I am having an awfully hard time overclocking. I have been through the other threads, AMD tutorials, video tutorials, other forums, researched errors, etc. However, each time I run Prime95, the overclock turns out unstable. I have a couple theories.

Things I've Ruled Out:

• 
  ■Power supply isn't good enough. I have a Corsair HX750i, and according to Corsair Digital Link, the system only uses about 350W when the processor is being stress tested.
  ■Cooling Problems. I have a Corsair H60 Liquid Cooling Kit. In stress testing at 4.3GHz, I saw temps of about 55C-60C.

So I started by using AMD Overdrive, the overclocks were completely unstable and never worked, and I constantly got the CLOCK_WATCHDOG_TIMEOUT error. I uninstalled Overdrive and started overclocking from the motherboard. I remember from a few months ago, before redoing my computer setup, I had the same FX-8320 overclocked to 4.5GHz by only changing the multiplier. I tried it again, with no success. My overclock was stable at 4.3GHz, where I have it right now. Next, I bumped the multiplier up 0.5x (4.4GHz). It was still unstable, so I increased the voltage the smallest increment possible. Same problem though. I kept increasing the voltage, but the same thing would happen: Cores would fail in Prime95, then the computer would freeze and go to CLOCK_WATCHDOG_TIMEOUT. I eventually ended up with the voltage at 1.4000v. The stock was 1.3250. Almost nothing had changed in the errors.

Do I need to keep increasing the voltage, or do I actually need to turn it down?

Also, my motherboard is a GIGABYTE GA-970A-UD3P (rev. 1.0). It is a 970 Chipset. The motherboard itself is good for overclocking, but because of the 970 chip, I'm not sure how safe it is. The processor might be using more than the motherboard allows.

Thanks in advance for help I get from anyone. I'm starting to wonder if I damaged something, but everything is fine at 4.3GHz.

Since you are using a AIO liquid cooler the VRMs are overheating. And the thermal paste between the heatsink and VRMs has dried out.The heatsink between the CPU and the rear connector panel NEEDS good airflow over it. This is what controls the voltage to the CPU. And produces a lot of heat.( The one that does not have Gigabyte on it.)

First try pointing a fan so that blows on the VRM heatsink. If this fixes the problem then the paste is still good.
If not then you need to remove it clean all of the old paste off with isopropyl alcohol and reapply with new thermal paste.

The motherboard has 3 different thermometers on it. I don't know which goes to where, but the highest I've seen on one was 58C, and that was when I was running a 4.6GHz overclock. Is this too warm? Anyways, I have a 140mm fan right next to it removing air from the case, and there is a 200mm fan on the opposite side panel.

What would the type of fan I buy for it be?
