So that if they are both enabled they will cause an instability. Also, it could be a voltage issue, maybe the voltage is not sufficiently stable with 4 cores running, or crosstalk internal to the chip. It could be anything like this, and there is no realistic way to find out that I know of. You should be happy you got a free core out of it and leave it at that IMHO. the elve September 8, 2011 9:03:08 AM Best answer selected by the elve.
