im guessing your stock speed is 200*14 (2.8ghz) yeh? well 29 mhz is a LOT when you are on a x14 multiplier, about 400mhz extra, youd be better off trying to drop your multiplier down a bit.

BUT having said that, it might be too much for your RAM or CPU to handle, a more sensible overclock would be 215, that will give you an extra 200mhz.

i really suggest DDR500 RAM or faster for that type of overclock, and a good motherboard.

well the 939 athlon 64's overclock quite well, some people reported gettin 3200+ or 3400+ up to 4000+ speeds (which is more FX-55 rating), i imagine an arctic freezer would do the job quite nicely. theres a good zalman cooler which in tests had better results than watercooling but unfortunately its for P4's only
