I've done some reading but i really cant get this out of my head. There are still a couple of things i need clarification on and i hope you guys could help me. I've managed to OC my pc using the clock frequency or fsb and the multiplier. Im using an Asus M2N Sli Deluxe mobo. Now i dont have that HTT multpiplier you talk about or if i do have it i dont have control over it. Can you explain, if its so important to overclocking how can some mobos dont show it or give you control over it. The other thing is the ram devider which i read in a thread to be set to 133 which is the lowest. I have an AMD 6400+ and well my mobo allows me to set ram frequency only 400 533 600 and 800 is that my ram devider? If i dont have control over those things on my mobo does it mean it controls it automatically. I hope this isn't too much junk for you guys. I've done a lot of reading and im really kinda tired ot trying to sort things out in my head.. i need a human to explain it. Thanks again for any of your support.
