How much can I OC my FX 4100 w/ a Hyper 212 EVO ?

Thanks guys for the help.And yeah,I decided to order it on tuesday.It's gonna ship on friday,im going to install it,see my temps and probably OC my CPU from 4,0 to 4,4 / 4,5 GHz :)

Isn't the stock speed on that CPU 3.6 GHz? I think you'll have trouble with it getting to 4.4/4.5 without getting close to the max voltage. It also might not be wise to do that on air cooling, but I tend to be a little conservative when it comes to OCing. YMMV, and it depends on how the CPU was binned.

BTW, here's the spec on your CPU:

AMD FX-Series FX-4100 - FD4100WMW4KGU / FD4100WMGUSBX

Keep in mind that the max Vcore is not published by AMD.

You might be able to get the CPU to 4.5, but I would use watercooling if it were me. It will last longer.

@Mellon Head the stock speed is 3,6,but currently it's on 4,0 .
What voltage do you recommend me ? Also,could you please explain me what voltages exactly are ,since I am not that good in understanding how PC's actually work.

I'm afraid I can't recommend any voltage. I don't know what the max is, and it would be irresponsible for me to do that. It might wreck your hardware if I tell you a voltage that is too high for your chip. I'd feel bad about that if it happened.

I can explain the voltage, though. The CPU uses a small voltage for power, among other things. It has a nominal value, like say for example 1 Volt. (And keep in mind that these are only examples.) That might be the voltage the CPU uses at it's normal clock speed, and everything works wonderfully. When you're overclocking, the CPU needs more power, so sometimes you have to "bump" up the voltage a little bit, say 0.025 Volts to get it to be stable at the new clock frequency. So now we're at 1.025 Volts and the computer is running fine. Let's say we want to increase the clock speed a little more, so we add 0.025 Volts more to get it to be stable again at the new frequency. Now, we're at 1.05 Volts. With the added voltage comes more heat that the CPU has to dissipate. The more voltage you add, the more heat gets generated, and the faster the CPU clock runs, the more heat gets generated. This is why you need good cooling if you are going to overclock.

When overclocking, you can only add so much voltage before you hit a wall. You reach your maximum stable overclock, and adding more voltage doesn't help, and will likely wreck the processor. The better your cooling, (usually) the higher your maximum stable overclock will be, but it's a very fine line between maximum and damaging your CPU. That's why you never want to go over your max VCore voltage. It will damage the CPU very quickly if you do. The key is very small steps, but you have to know the limit to start with to make sure that you don't go over it. In your case, the limit isn't published. Googling the limit only gave me values that other people had tried with, but not a published specification. Personally, I would prefer to go with a published spec than someone's say so. It's safer.

My advice to you, if you really want to overclock your PC and you have limited knowledge about how they actually work, is to read as much about it as you can BEFORE doing it. Go to overclocking forums and learn what you are doing. Then, and only then, OC your rig. There is a lot more to it than just jacking the multiplier and voltages up. It's a fine art that must be done carefully if you don't want to have to replace your hardware.

That's the end of my sermon for today.

When over clocking FX chips the best way to find out voltage is to increase little by little till it fails to boot or load the os then you bump it up

Motherboards that support the llc feature load line calibration will help you keep a good voltage with out putting a high voltage in place pretty much keeps a constant voltage on the CPU so when you run it the voltage doesn't drop and cause instability

now voltage wise ussually 4.2 can be from 1.400v to 1.420v llc at medium 4.4 you can do 1.43 1.44 anything like 4.5 ghz requires at least 1.44 to 1.45v to run at that speed and temps shoouldn't go passed 70c i think with the 4100 with the 8350 it's 62c the TDP is 95w and the 8350 is 125w
