read forum rules if you have that sort of question.
Your motherboard has heatsinks for the VRMs and northbridge chipset, and has an 8pin PCU power plug.
Id say you are good for going to 4GHz no problem.
You have a disadvantage though. your cpu is a 125watt TDP. if you were on a 95watt TDP 8 core you would have a bit more success
you can hit 4GHz easily though. go into BIOS, disable turbo and cool N quiet and any power saving modes.
Then set your cpu to its turbo voltage. cpu-world lists your cpu as 1.425 volts.
If you set 1.425 volts, set your multiplier to 20x, you should be at 4GHz. stress test to verify it is stable, and WATCH YOUR TEMPERATURES
HWinFO64 reads a lot of temperatures, is free, and a great tool to see how high the temps get.
use interburntest, should have agent GOD somewhere on it, it is the correct version to use. majorgeeks should have a download for it
EDIT once you find it stable, you can then drop voltage one tick, or to 1.415 if you have manual input available, and retest. the goal is to lower voltage at 4GHz so you can reduce heat and stress of the motherboard.
