I currently own an ASUS P4P800 motherboard with an AMI bios. When I try to overclock from my bios, I can't seem to be able to change my FSB settings. According to my motherboard manual, the FSb setting is automatically detected and can't be changed. Yet, the bios also provides AI-Overclocking which seems to be able to change it when I use it and check with CPU-Z. So, the only way I can overclock is using the AI-OVerclocker. Can someone please explain what is going on?
Also, how come my bios doesn't provide a setting for the FSB : DRAM ratio? Once again, AI-Overclocking seems to be able to change it when I check with CPU-Z...
One last question that doesn't have to do with the bios, is there an optimal ratio to set for FSB : DRAM when overclocking an intel?
