Anyone getting problems with this board P5e3 Deluxe DDR3 and vcore/vdroop Mod ?

I did the vdroop/vcore mod and i am having really delicate issuse with this board. Increasing the Ccore above 1.8v will cause the board to shut off as if OVP is kicking in

Also the board is having trouble dealing with NB voltage above 1.7v it will crash and not run 3d

My board is on cascade cooling and NB temperature never goes above 20oC as in a cold garage.

any input please.
