Ok I have a MSI Kt3 Ultra2 motherboard and an Ahtlon XP 1800. I have some no-name crappy pc2700 memory too. =P I was overclocking and I got to the setting 11.5 x 152 and when it was posting it said I had a Athlon XP 2400 in there. Then when I was going to check my email the computer just rebooted outta no where. I turned the FSB down to 150 and the post reports it as a 1800 again. Im just wondering why it said I had a 2400 and why it rebooted outta nowhere.. (imma n00b @ oc'ing)
