I have a 486DX/33MHz system, and I have been told by the manufacturer that
the motherboard is upgradeable to 50MHz by plugging in a new crystal and CPU.

Question:  	Is it possible to plug in (say) a 40MHz or even a 50MHz crystal
		into the board *without* replacing the old (33MHz) CPU? 
If so, is there a performance improvement or will the 486DX 33MHz chip just
burn itself out, ie, has it been internally hardwired for the specified clock
frequency of 33MHz?  I would like to hear from anyone who has attempted this
(with/without success).
