I have the Asus ME & qx9650 batch L739A664 pack date 11/21/07 vid 1.25 (good oc batch apparantly)

i have been unable to get stable oc above 3.7Ghz @ 1.328v (cpuz) (MB Bios 1104)

I have good temps although im not convinced tjmax is 95 for this chip.

Ive bumped the nb volts and tried various bumps in fsb termination voltage, vcore to 1.4+

I am not looking the max overclock but around 4GHz+ at minimal voltage increase.

My cpu cooling is thermalright 120 lapped and my NB is cooled by reserator 2 watercooling 40c idle 44 load.

my ram is ocz ddr3 1333 @ 1480 (2t) 777 20 @ 1.82v everest.

ive tried even the most common oc for this 400*10 @ 1.4+ volt but bsod randomly. At my current oc ive had no bsod at all = 370*10 @ 1.328v

ive been overclocking since nforce2 mobos and mobile xp 2500 barton chips.
