I want to try and oc my 1800+ TBredB. The motherboard has 2 jumpers that let you select 100fsb or 133fsb. It's currently at 133fsb. In the bios under the "Frequency/Voltage Control" section, it allows me to select from a list of fsb/pci ratios to overclock. The problem is that I can't find anything in the bios that will let me change the core voltage or multipliers. Do I need to mod anything? cpu or motherboard perhaps? Or is my motherboard not going to be overclocked at all?
