I don't know about it, I don't have the option on my motherboard but don't suffer vDroop either.
It is a voltage setting that apparently helps with vDroop.

First of all set your HT to ~2000mhz - anything more can make the system unstable when overclocking. 2000mhz will be MORE than enough.

This doesn't sound good. What temps are you getting? Could be Thermal-Throttle or C'n'Q shutting down one of the cores or lowering vcore to stop it hitting TJMAX (which is around 72C i think, when the system shuts down to protect itself)

And i 'think' LLC (Load Line Calibration) and should be set to 0%, idk tbh; - set it to Auto if you don't know)

i lowered my HT link already and running prime now to see if it is stable and im getting 42-43c on all cores while full load in prime never goes higher and CPU 42 -43c aswell usally 1 degree lower then coers and motherboard 31c.

You'd have to have a damn fine chip in order to run 4ghz at 1.33 volts. You probably need a large VCore bump.
