I only have one 16BGC, so I don't know enough about them to say how well they overclock in general, but of all my 5x86s it's the best at overclocking. I believe this one will get me into NT4 at 180MHz, but will crash after a few minutes. Even with a tweaked voltage it's still not stable though. (tried everything from 3.3v to 3.95v). So the 16BGC is the best of all my 5x86 chips, but still not good enough. Strangely the only ADZ I have won't even POST at 160.

16BGC was my best as well, but not stable at 180 MHz 4V. DOS did fairly well, but not Windows.

That’s NOT a 486 but 5x86.

That was only marketing by AMD. The AMD 5x86 was also called 486DX5, as written on some variants. It's an ordinary 486 CPU (unlike the Cyrix 5x86).

Can you play MP3’s ?

You don't need an overclocked AMD 5x86 to play MP3s. Even a DX4-100 can do that already.
