Prime95 keeps freezing my CPU during stress test?

Hey everyone, I'm having a bit of trouble overclocking my PC with an AMD FX-6300 using Prime95 (64-bit).

My current specs are here:
AMD FX-6300 + CM Hyper 212 EVO
Crucial Ballistix DDR3-1600 8gb (2 x 4gb)
Asus M5A97 LE 2.0
XFX Radeon R9 270X
Corsair CX650M

I'm a real oob when it comes to overclocking, and I originally planned to overclock my system about +0.5 compared to stock. So I watched this video on how to overclock the 6300 in particular.http:// In this video, he overclocks it from 3.5 GHz to 4.3 GHz to those who can't watch it.

Okay, copied all what was on the video, step-by-step, save and restart, nothing bad so far. Now I download Prime95 (64-bit) and start a blend test. About five minutes into the test, my computer freezes. No warnings, no BSOD, no nothing. Just freezes like ice. I was monitoring my CPU heat and it hasn't climbed over 60° C, and I have nine case fans running full speed so I don't think it's an overheating problem.

Would anyone know how to fix this problem? Thanks a whole lot in advance.

Overclocking is an incremental process. You should not just "copy" someones video and expect the same results.

For one, you need to disable all the BIOS/uEFI features like Cool n Quiet, Turbo Core and the like. Secondly, you will need to start at a lower OC like 3.9 or 4.0 and make sure you are stable at those clocks first, before jumping headlong into 4.3 and higher, especially on a CM Hyper 212 Evo - a good cooler but still with short comings.

For a nooby OC, I would not recommend going over 4.2, if you do not know what your are doing.

You don't need to disable the power saving features, though it is a bit easier to manage the overclock if you do.

As for the overclocking itself, bump up the voltages to 1.375v, and if it's not stable, bump it to 1.4v. If it's not stable after that point, I suggest just lowering the clock rate and the voltages back to 1.35(which I'm assuming is the stock voltage...)
