I'm running 450MHz (4.5x100MHz) at the original rated voltage of 2.0V I was running the Celeron 300a without mod (i.e. original heatsink) fine for couple of weeks, but just to be safe, I added a 4-fan heatsink from ComputerNerd later on and it has already been running fine for the last five months.
