I have a workhorse computer which has given me 6 great years. It's an ABIT IS7 which has used a P4 2.4 GHz 800 processor.
Since the price of these old 478 processors have come down dramatically, I decided to buy a 3.0 GHz and overclock it. After reading some old OC reviews, I attempted small increments to the FSB. I decided to stop at the point which gave me a 3.45 GHz processor. One website claims that 3.8 GHz is possible with no problems.
I have no bootup problems at all. However, while playing some songs from an external hard drive with firewire connection, the song stopped playing. I tried exiting from winamp and then got a screen which noted an error and it rebooted. It was too rapid to read. This was after an hour or two.
I decided to look at the temperature in the BIOS while it rebooted. It read 49 degrees C, but obviously that was with no load. Is that an acceptable temperature? The problem I am having may or may not be related to this at all.
