Overclocking Unstability? (AMD)

[PvEdominator]

Hello, I'm trying to overclock my AMD FX-4100 and i can bring it up to 4.2 GHZ perfectly stable no problems, when i bump it up to 4.3, it will only last a few seconds (i am using multipliers) and i was wondering it was my PSU being limited by its wattage. My temps under load go to 62C (I am using the stock cooler, I know its horrible but I'm getting http://www.amazon.com/ARCTIC-Freezer-Rev-Cooler-Multi-Directional/dp/B002G392ZI ) I have turned offed C1E and C6 I think their called because I was automatically getting dropped down to 14x multiplier instead of my 21x. CPU voltage is set to auto. Thanks! Also if it is the PSU, could you guys recommend me one? I'm using the case Apevia X-Dreamer3.

Specs:
AMD fx-4100 3.6GHZ (OC to 4.2GHZ)
Allied 300 watt PSU
AMD Radeon HD 7750
Gigabyte GA-78LMT-USB3

Allied supplies are not the best quality. Your 300watts is probably a glorified 225watts. As for a replacement, I've always been fond of Antec. Get yourself a solid 500watt or better supply and you're golden. As for your overclock, why not up the vcore just a notch, (once the new supply is in!) and see what that does for you. Also, be patient and wait for that new cooler to come in. It'll definitely help.

Thanks for the fast reply, and ill order the PSU as soon as possible, and I'm very excited about the cooler as I personally don't like the temps, especially when I'm gaming, or Emulating which uses single thread performance (which is why im overclocking because bulldozer CPU's aren't the best single thread ) What do you recommend for the Vcore?

I would take it up one notch at a time in the BIOS. Usually this is .05 volts at a time. Test your speed, run Prime95, and then go from there. You really don't need to add a lot more voltage. Keep in mind that increasing the voltage inherently decreases the overall life expectancy of the processor. This being said, I took an Athlon 3200+ from 2.0GHz to 2.5GHz and it ran for years, (back in the day!) Each processor is unique so there is no golden rule for which vcore works at which speed. It's all trial and error. Going from 3.6GHz to 4.2GHz is still a respectable overclock.

Nice, and thanks, I'm aiming for 4.4-4.6GHZ, mainly for Emulating since I tend to play PS2 games (ya very old gaming ) whenever I can't figure out what games to play in my steam library.
