High overclock w/ FX-4350 on 4+1 power!

I have an Asrock 970m Pro3 Mobo, and as cheap as it is, it gets the job done, but while playing games, I notice that my CPU is a bottleneck, so I've been overclocking.

Reading up, I hear that it is not safe to overclock too much with a 4+1 phase power delivery motherboard. (970m pro3). Is it safe to do high overclocks (5Ghz) with this 4+1 system? (*I don't really understand what this means)

Right now I am running 4.65Ghz @ 1.3625v and my temps are ~43c on all cores, 40c at TMPIN0
I hear that since it only has 4+1 phase power, it is unsafe to overclock too much, but I can't find answers anywhere!


So do you think it is safe to overclock my FX-4350 to, say, 4.75Ghz?
(Just installed the corsair H60 cooler and it keeps my temps so low!)

Thanks in advance!

Hey there! You should be fine to go to 4.75ghz. Just a few tips and ideas for you before you go any further.

The maximum core voltage you can have on that quad core is 1.43v. Never at any time exceed that otherwise you risk damaging your CPU.

You should actually be able to hit 4.82ghz at around 1.368V. You'll want to download a program called Prime95, run the torture test on all 4 threads. If your CPU temp goes over 70C at anytime, you will want to back down the overclock. Yes it is safe to keep it in the low 70's but when your gaming, you can find yourself with 100% core capacity and that heats your CPU very fast, far beyond that low 70's you might see in Prime95.

If you reach 1.4V then you will have reached your processor's limit and that will be when it is time to stop over clocking it.
 


Thank you! So with a quad core, you dont need a 6+1 power phase Mobo?--thats good to hear, because the next board up is a lot more expensive for the same features.

I've been using AMD OD for stress testing, it allows me to step up the multiplier and voltage without rebooting, this way I can find what works before changing bios settings. Does Prime95 work better for stress testing than the built in feature that comes with AMD OD? Is that why Prime95 is so popular?

Thanks again.
 


I think it is because Prime95 actually causes stress to your CPU and it also is free. I have always used 3DMark for stress testing my CPU and GPU. But people swear by Prime95.
