Ok so i recently built a system and im looking to over clock it. Now I am having some trouble. I am trying to find my max cpu speed. I drop my htt to x3 or x2, the cpu multiplier to like x8. Then i set the htt to 300 mhz. My system failed to boot, so i dropped it to like 250 mhz. Giving me a fsb speed of 750, and a core speed of 2000. My system still fails to boot. But if i keep the htt multiplier at x4 i can get the system to boot with a 9x multiplier and a htt speed of 250 (core speed 2250) Why cant i seem to get the system to boot with any other htt multiplier other than 4?
