Hey there... I am trying to overclock my AMD Athlon 1.4GHz CPU. I have an ECS K7VTA3 v2.0 motherboard with a newly flashed bios. I know the overclocking is very limited, but it can go to 1.575GHz. I however can only get it to go to 1.47GHz. Why is this so? I have seen other people online that have gotten it to 1.575GHz! Well, actually... mine can be set to run a 1.575GHz, but after it lists the components such as the cd-rom's and the hard drives (right before windows loading screen), the screen will just go black. I have to go back into the bios and set it to a lower setting to get my machine to boot. Whats up with this! I want to run a 1.575GHz!!! Help me out here fellas. I am running Windows XP by the way.
