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.
