Yesterday I overclocked my AMD64 to 2.2 ghz (200 mhz) and tested the idle and load temps. They never reached above 35C during benchmarking. Acouple of hours went by and I joined a scrim later that night and after about 1-5 mins of being connected to the server, I get a windows XP error box saying that HL.exe has caused an illegal error and asks if I want to report it. Well this happened everytime I joined the server (about 5 times) Until I realized why it was doing this. So I rebooted and went back to the default stock speed of 2ghz and the problem stopped. Is there some known issue with overclocking that I am missing here thats causing this error? I am guessing it is not overheating problem because my temps are staying below 35C and anything beloe 50C is normal.
