This is my first build so i dont want to melt the processor. I want to know if i should leave the CK_RATIO at its auto setting and just change the bus setting to 133? If i do will it auto detect the mutiplier? I just got this motherboard and an XP 1800+. or should i change the clock ratio to 11.5 and change the bus to 133? thats correct right? 133x11.5=1529.5? Or should i jsut leave the default setting?
