Hello. It's been a while since I've posted. My question is: can a microcontroller be overclocked and still be reliable? The reason I'm asking is because I'm planning on using a Philips 87c51UBPN that I already have to make a one off MIDI project. With a regular 87c51 at 12 MHz I can get the MIDI baud rate (31.25kB) by using a uart divider value set to FF, the highest possible setting. I figure that I could run a chip at 24 MHz with a divider at FE, or at 36 MHz with a divider at FD. I know that the 87c51UBPN is rated at 33 MHz. Could it be pushed to 36 MHz for maximum processing speed without ill effect?

Thanks for any experiences or suggestions!
