I have a new 2.0 GHz P4... would I need to set the CPU jumper to 100MHz or 133MHz... i'm assuming 100. I'm new to building a system. I appreciate the help. Would it matter what type of RAM to use (other than being compatible with them board). What I mean is can I use 266MHz PC2100 with it? (the board takes pc100/133 or pc2100).
