all FX cpu can hit up to 4.4GHz on stock no problem so i think its something else ?
This is absolutely not true. My FX-6100 can do 4GHz on stock, but anything above requires additional voltage. I also can't overclock my CPU past about 4.3GHz. It is not stable at any voltage above 4.4GHz. It could be my CPU or my motherboard.
To the OP, keep in mind that every chip is slightly different. Cheaper motherboards tend to not overclock as well, though I'm not exactly sure what you're running.
I would recommend overclocking with your multiplier only, that way you don't have to mess with RAM timings. Check for voltage droop and enable LLC if you need to. That should fix the voltage drop. And sometimes you have to offset the voltage in the motherboard by a greater amount that you'd think so that it actually uses the voltage you're looking for. There are some other settings you can enable/disable to make overclocking more stable, which I would recommend researching. Did you turn off turbo boost? You'll definitely need to do that when overclocking.
