I did try f4f and f4l with the same settings but i still had the multiple restarts which resulted in the overclock failed message in the bios.As of now i have:
bclk 170 x20
vcore @1.2875
vtt/qpi @1.18
cpu pll 1.84
qpi pll 1.14
ram @9-9-9-25 1.66v
qpi/unicore and mem set to auto for the momment.
All cpu features of apart from HT.

Just ran a 1 hour test OCCT ( i know this wont prove stablity i will be using prime 64 and linx to fully test)
cpu idle 34,31,35,35
Load around 63,62,64,64



This will be my starting point to fully test stability.
