Kevmarks, that is a great o/c on a Tbird, but a Tbird needs GOOD COOLING to o/c that high. Tbird 1.4's do get pretty hot, and u need a good HSF for it. I think u mentioned swiftech, so what HSF is it? and what fan is on it?
PS: an XP 1900+ costs the same or less than a p4 1.6A, and with some vreativity they go to 1.8ghz pretty easily, which in turn easily smacks atound a p4 at 2.4ghz, which is an above average o/c on a p4 1.6A.
A few people get 1000mhz o/c's, but most get to 2.2-2.4ghz.in that situation the cheaper Athlon performs better, and IMO tweaking an AMD system is a lot more fun, there is more stuff to mess with.
dreamtfk, i ran my TBIRD with a 10$ coolermaster stock HSF with a thermal pad and 2 80mm like 20cfm case fans, and it topped out on the hotest days at 55c at full load, after hours.
Instead of having the shop troubleshoot it, do it yourself. You will learn a lot and gain valuable knowledge and experience. I would never dream of letting someone else troubleshoot my comp. And i havent had a problem yet that i could'nt figure out and fix.
like was said earlierr, get a digital thermometer (compunurses are 15 dollars at Sidewinder) and find out if the temp is accurate. Remember, putting your own TLC into your comp is what makes it special, everything done to it is custom and by you. u feel a lot better about yourself and your PC when u DIY.
