Ok. My question is that since the ASUS(dead) mobo had 800MHz and the Foxconn has 533MHz, will it still work with my Pentium 4 3.0GHz 800MHz FSB? Will it slow anything down? such as will the 533mhz on the mobo cause the CPU to show something lower than the 3.0GHz?
Any help will be appreciated. I can provide more details if required.
Its either replace the mobo, or just upgrade the system since its pretty old.
It will work, and you should be able to adjust the BIOS settings to get 3.0GHz and to get your RAM running at its designed speed too. You can download the Foxconn manual here. I checked the BIOS settings section, but it has limited info - you'll have to check the detailed settings after you get the system running.
