Lulz, cuz your overclock might be unstable. Have you tried upping the V-core?

There is absolutely NO guarantee for ANY sized overclock. For a 3.9ghz OC on any Athlon II processor you've done well.

You can up the voltage as high as 1.5 or so on half decent air cooling (yours is average), but don't bother beyond that. Adding a little CPU-NB and NB voltage can also help, but the real lesson to take away here is that 4ghz simply may not be possible.

How stable is your "3.9ghz"?

If you've not hit AT LEAST 2 hours on Prime95 blend then you've not proven your chips ability to hit 3.9 in my opinion.

You need to go higher. Your safe (temperatures allowing ofcourse) til about 1.5ish. When it becomes unstable it either needs more voltage, OR you have reached the thermal threshold. But with that voltage of 1.36 I doubt you reached thermal threshold. So, that leads me to believe that you need more voltage. Try bumping it to 1.45 then booting at 4 gigz. If it does, then just back it off til it doesn't boot again, and now you know at what voltage you can boot at then you can work on getting it stable.
