I have been using a SDRAM module (168 pins) on a 100MZ motherboard and I would like to know if I can use it on a 133MZ board providing the pin connections agree, advice greatly appreciated as always Solly
You can use it - but what speed you run it at depends on the module itself.
If it's a 133MHz module, then it should run happily in the 133MHz board.
If it's a 100MHz module, then you can run it, as long as you change the memory speed setting to 100MHz. The speed setting for RAM if often labelld somethng like Default, or Default-33MHz - you would need the Default-33MHz.
Unfortunately the settings descriptions are a bit unstandardised, so if in doubt about what to select, ask again.
