Have Some Questions About Overclocking - Need Some Help

[PHATJACK]

Okay, I am a complete newbie when it comes to OCing. I've been working with computers for some time now, but have never OCed.

I will be building a new machine with an AMD Athlon XP 1800+, MSI K7T266 Pro, and 768MB of Crucial Cas2.5 RAM on Windows 2000. My question is, if I OC my FSB from 133, to say 145, what is it stressing? In other words, what am I taking a chance with?

Also, what is all this talk I hear about 1/4 dividers and the such?

Thanks!

If your change your fsb to 145 your pci bus will go from 33mhz to about 36mhz. Most peripherals can handle that, however cheap peripherals and certain hard drives (like my stupid IBM deskstar 45gb hard drive) will not like it. Hard drives may crash and burn at the slightest bit over 33mhz. Unless you have a crappy hard drive like mine you should be ok there. If I recall correctly agp runs at 66mhz, so this would bring it up to about 72 or 73 mhz. Most newer video cards can handle this, if you have an older card like a tnt and some tnt2's they may not be able to handle it.
As for dividers, the FSB runs at 133mhz. Pci has to run at 33mhz so it runs on a 1/4 divider. Agp 66mhz so a 1/2 divider.
Some new boards like the Iwill XP333 coming out at the end of this month offer new multipliers that will allow you to crank up the FSB to 166 or 200 and the pci/agp will still run at 33/66mhz.
For people like me when I get the XP I'll either have to replace my pos deathstar drive or try reconnecting the L1 bridges.
