There is a lot here about OCing Athlon T'breds, but I have: Athlon-XP-M Barton in a laptop, 1.450 V. The max core speed is 1799 MHz w/ 13.5 multiplier, and min is 532 MHz w/ 4.0 multiplier. It's Socket A, the bus speed is 133 MHz, and the rated FSB speed is 265 MHz. The MB is a HP 0024, chipset is ATI IDCAB0, and the Southbridge is ALI M1533. BIOS is Phoenix KAM1.54 12/11/2003. Memory is 1024 MB Micron Technology DDR PC2700 (166 MHz). CAS Latency is 2.0 @ 133 MHz, 2.5 @ 166 MHz. 99% of the time my computer is number crunching. I would never think of OCing in the summer, but now that cooler weather is here overheating is less much less likely. I would appreciate suggestions/advice, but I don't want to open the case. Steve

I don't really know much about laptops but I have overclocked many desktops. Having said that I don't really recomend doing it. I have found that you end up getting bottle necked by your internet connection. Yeah your computer is faster until it fries but your connection speed won't change so you don't really get the full effect of what you have done. Many when they notice this instively try to go further and fry their cpu. for the average user it is just not worth it unless you can afford to replace the bad equipment afterwords. Likely Practice makes perfect but only if you practice perfectly!

I really don't care about internet speed. I have (relatively slow) DSL anyway, and my main interest is increasing the speed of the number crunching. My reference to cooler weather is significant. I,m surprised I didn't fry the thing this summer, before I learned how to throttle back on % of time the CPU ran. I would probably be more interested in increasing the Bus Speed from 133-166 MHz, since RAM is capable of that. Of course, that would probably result in the CPU increasing from 1.8-2.25 GHz, a 25% increase in speed. That does sound ridiculous. I was thinking more along the lines of 10%. I've done that before with a desktop. That would require a Bus Speed of just 146 MHz, resulting in a CPU speed of just 1.98 GHz. That might be possible. By the way, CPU-Z returns results of: Bus Speed 133 MHz, Rated FSB 265 MHz. What actually is front side bus, and why is the speed different? Now I just need somebody who can tell me how to tinker with the appropriate settings. Unless, of course, somebody has knowledge it would be pure suicide. Steve
