It's been a couple of months since I installed my OC'd Celeron 300A, but as far as I know, nothing has changed. That is locked is the clock multiplier, not the clock speed. For the Celeron 300A, it's multiplier is locked at 4.5x. Therefore,
FSB* Mult Speed 66Mhz 4.5 300Mhz 100Mhz 4.5 450Mhz
FSB = Front side bus (ie, memory speed, and 2x PCI speed with older socket 7's <pre Super-7>)
And remember, folks, with the Celeron you get L2 cache running AT the core speed, not 1/2 the core speed as for P2's, nor at the FSB speed as for Socket 7's.
I haven't looked into the new socketed Celerons yet, but I imagine they are similar.
