HI, Soybean, OK what I want to do is put a intel T7500 processor in place of my T2330 I have now. I don't think the NB/SB will have mush say as the motherboard supports 800 FSB. At least I don't think so. I don't know jack about chips pci, nb/sb etc. I am just trying to put more speed in my laptop. It's just something to see if I can do it and will it work the way I expect. Reading that article said alot and made me not want to read to much into it as it would only make me doughtful of what I'm trying to do. Thakks for the info and any info you can give on this processor installion would be great. I have a Toshiba A205 Satilitte S5804. Thks
