I just built me a new system almost a month ago. I did not think I was going to overclock but decided to. I have p4p800 2.4c cpu maxtor 160 hd and radeon 9500 pro video card with kingston 512mb pc2700. I was thinking with that memory I could not overclock any, but when I go to the bios I select overclock 30%. After I did that I went to www.pcpitstop.com and ran the little test. It said the computer was running at 3142mhz. I restarted and checked the CPU temperture and it was going up to 103F. Is this safe or does it need to stay below 100? the MB temp was around 92F
