I just purchased two sticks of Crucial 512mb Ballistix ram(3200) and i already have a regular stick of 512mb Crucial ram on my Asus Black pearl motherboard running a P4 2.4ghz. It allows up to 2gb of ram so I know i'm cool there. When I try to put all of them in the system will hang and on the next startup I get a message that says the Clock speed was wrong or something, but if I only put in 2 of them everything is fine. I don't know anything about the speed settings in BIOS and I read the FAQ but do not understand what I need to do. What speed do I need to set these to?
