| Correct. But there was a rumour going around years back that AMD got lazy with the 16KB version of the DX4. Rather than making a totally new chip, they just relabeled some 5x86 chips. |

| My AMD DX4 100 16kB is 3x/4x. |

| Great, thank you for testing. This means that to run an AMD Am5x86 at 166 MHz (2x66), you need to use a late production DX2. |

Yes, that was actually a problem for me, since I wanted to simulate a DX2 16kb and instead ended up having yet another DX5  |

That's something I didn't know. I thought you could set any multiplier you wanted to. So some chips are limited to 2x or 3x and others to 3x or 4x? What happens if you have a 3x or 4x DX4 and you set the motherboard to run at 2x 50Mhz?

There is only one pin to select multiplier,
so if the chip can e.g. x3 and x4 it is not possible to set anything else. |
