errors that quickly mean a super flaky overclock.
usually it is:
a) not enough voltage to the cpu
b) your ram is overclocked too far past its specs.
c) you may have tried to go to far with first overclock. try starting at 3% or so.
a 4000 will overclock well past 8%, so i know you haven't gone past its specs. you should be able to get more like 20%+. depends on your ram as well, tho.
what is your ram speed, stock settings and what do you have it set to in bios?
did you re set your cmos after the first crash?
if not, that could definitely be causing it to fail p95.
you have to clear cmos every time it crashes, or you run the chance of developing all kinds of wierd bugs when you try to overclock again.
i would also suggest turning off the ai overclock deal and making all the adjustments manually.
