yeah i posted specs on my notebook for the hp pavilion zd8000 and i need to downclock to cool down the cpu because it gets so hot it burns me, i have turned off the hyper threading, which won't make a huge difference but a little, some mobo companys make it so you can overclock and such but the P4 preston doesn't allow it, so i have to figure out what i can do to help my little , well not little but huge problem, i have searched and such but im wondering about the frontside bus speed should be lowered to when i lower the cpu speed, cause if ones changed the other as to be changed to, thanks again everyone, its amazing how great this forum is, most are people who just make fun or critisize people who don't know everything.
