Not especially. I'd just advise not jumping straight into high overclocks - work your way up slowly. Try finding your FSB max and at which points it will need more voltage to the NB chip (not the same as CPU NB). To do this, drop your CPU multi and RAM speed to below stock so that when you raise your FSB, neither of those two things will be responsible for causing instability. Isolate the one thing you're testing so that you know what's causing your system to crash.

Once you've got your FSB all figured out, then you can try messing with memory and CPU separately. When working on the memory, I'd advise trying to get the tightest timings you can as opposed to higher clock frequencies. Do this at your max CPU overclock.
