You got a taste of the goodness thats overclocking and want more already............😀
Wonders if I should let him know about the time that it just won't boot anymore and whether to let him freak or not...........
At some point if you keep overclocking, your vcore will no longer be high enough to keep the processor stable and it will simply not boot anymore. This simply requires you clear your cmos (which on some nice motherboards, if you hold your INS key as you press the power button it will boot at default speed and let you either turn the fsb down or the voltage up).
You should monitor your temps in bios and if they start to get much over 60C, it is time for a new heatsink or to turn the overclock down.
You should also run a stability checking program. I personally like Prime95 to check on processor stability. If it errors then its not stable. It should be allowed to run 24hrs or at least overnight. If your stable then try a little higher, until it either doesn't boot, it has registry errors when it boots or it won't pass Prime95. A lot of people like to unlock the multiplier on their XP's and keep their fsb close to a known pci bus multiplier 100/133/166(only for a few boards) or there are some boards that allow you to lock the pci/agp bus so increasing the fsb (which in turn increase the pci/agp bus) doesn't cause corruption or crashing.
There is more to overclocking, but your in the right forum. You should do some reading.....😀
