i can try 1.41V and i can add an extra 100mV to the NB to make it 1.25V but is that safe?

i already added extra voltage 40mV. i don't really feel comfortable added that much voltage to my CPU i wont go over 1.45V no matter what just paranoid i guess.

Yep that's perfectly fine, you're not runnnig stock cooling, as long as your CPU Temps stay under around 55c under load (Note, CPU Temp not Core Temp, and load meaning Prime95 or equivalent), you should be fine with the voltages up to 1.5v CPU and 1.4 NB.

I don't recommend going as high as 1.5v just for an unlock, it's really not worth all that voltage for an extra core, when you could likely hit a nice high OC with much less voltages on three.

Try up to 1.42-1.44v on the Core and 1.311NB, if you don't get an unlock, I would give up.

well i ran prime 95 and it instantly locked up but i went into my bios and reset everything and from the glitch it left the core unlocked and im running prime 95 right now for more than 15 minutes and no problems and the heatsink isn't even that warm. I have a feeling its my motherboard causing the instability i will know for sure when i get my new asus board next month

i got the top 140MM fan pulling air onto the cpu cooler and the rear fan venting hot air out and i got an actively cooled fan on my NB plus a 160CFM side panel fan blowing cool air onto it

If its locking up during prime its probably your motherboard or ram, try downclocking it or pumping more voltage into it.

i got it stable now i used the glitch to my advantage lol what i did was turn the cor unlocker on and reboot then i loaded up default setting and it left the core unlocked then i upped the cpu voltage to 1.41V and been running prime 95 for over half an hour no problem and the heatsink isn't even warm
