Thanks Macro. Im having trouble finding out what FSB my mobo is but I think its probably the lower. I also can't find out the max speed of 478 processor the mobo will take. Im running a 1.8GHz Celeron processor with an Imperial 1.03 TriGem Computer, Inc.(WMT478/NWD) mobo with BIOS PhoenixBIOS 4.0 Release 6.0. Any ideas on how I can find out what the max speed of processor I can buy?
