    hi andypepp... three weeks ago i was in your shoes ..
    with same Mother board & CPU ... then oh mighty Lsdmeasap came to rescue ... since then i've manage to gain some knowledge ..

    so i can give you this template of settings ... they passed for me many possible stability tests (prime 95/memtest/occt/intelburntest)... though if i were you i would test them anyway on my computer.

    Code:

    Channel B Ref [ 0.900 ]...................[0.9V]
    if it will work fine for you...then i can give you my current setting that overclock the cpu to a stable frequency of 3.8ghz .

    but i think you don't want to jump high and the fall low ...you better go up the stairs of O.C - step by step .

    Good luck

    p.s: you might find more detail and answers in the stickys and in this thread ...
