Lpc2000

Hey, any more tests done on this?

I remember back in the early pentium days, getting a P133 and having 
a very good probability of overclocking to 200MHz.

You could always do an overclock using the same method that is used 
for SDRAM -- SPD eeprom I believe it is.  Since the overclocking can 
be done via software, set up a brute force test that runs on every 
chip, and keep upping it until it becomes unstable :)

On that note, since there is an internal multiplier for the 
frequency, is there any benefit to having a higher frequency 
external oscillator?  I.e. Is there any difference to performance if 
I use an external 5MHz with 12x multiplier, or external 20MHz with 
3x multiplier?
