overclockig my 6850 vcore?

[QuadDragon]

well I have been working on gettng a nice stabe overclock

I ran the fsb up to 400mhz to give me an overclock to 3.6ghz ddr 800
at stock vcore 1.35
prime 95 faulted in 1 min

so I jumped back in and raised the voltage to 1.4v
system ran prime 95 for 4 hours and faulted

so I jumped back in and raised the voltage to 1.42v
and am tesring it now

What is the max vcore I shouldgo with on this chip.

So far the max temp I have reached is 50c under full load with my ultra 120 extreme
27 idle
