I currently have AMD II and I have done a lot of overclocking with AMD machines. I am planning to custom built Celery or PIII system. Can you change the multiplier setting and system bus on both of them? I've heard that you can only change system bus on celery. Also, can you buy un-locked PIII processor? how do you unlock it? How high can you oc PIII450? Also, which celery can break 600MHZ mark ?

Thanks in advance.

Multiplier, no. FSB, yes. The best would be the Tualatin versions. Ol' man reports great OC potential on the Tual Cel by using the 133fsb.
Unsure about mobile versions of P3.
Recommend reading up on the Coppermine and Tualatin versions at the cpu history sites -- just google. The Tual requires a different motherboard. It's still a socket 370, but not pin compatible, ie. it'll go in but not work. Adapters for the earlier Coppermine boards are available, but bios upgrades may not be. Most of the used stuff out there will be Coppermine, so be careful.
