Hi, all!

Got an interest CPU AMD-K6-2 475/ACK from a scrap.

This is a notebook edition of simple K6-2 with 2.0 V powering.

Do anyone know how these CPUs are made? They was manufactured with own technology differently from regular K6-2, or just separated by ability to work under low voltage?
In the second case overclocking potential must be promising...

Thanks

They are the same designs as the desktop, I think they use a slightly more expensive thicker layer or something to make them lower voltage. They do not seem to be substantially different from desktop for overclocking. So you might get 500 out of it, but not a whole lot more, the binning seems to have been tight for parts under 500.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Probably just a binned chip which was tested to work at lower voltages.

You was rigth 🙁
Even with 2.2V supply maximum stable freq is 500 MHz, on 550 failed to boot Win2K.

Shame 🙁 ... ah well you can try taking it the other way 450 on 1.6 to 1.8 for fanless system.
