I've been trying to find an AMD Athlon Thunderbird 1.4 GHz 200 FSB, but I can't seem to find any, mostly they have the 266 FSB version, does anyone know what would happend if I use the 266 FSB version? I've checked the mobo website and it says it doesn't support that speed, but I've heard someone saying that it shouldnt be any problem. I'm using the K7T Pro2-a MSI mobo. Pls. respond if you have any comment or ideas. thanks
