Windows 95 CPU limit

Some people say that Windows 95 CPU limit was 2.1ghz (anything faster than it will get system protection error.) .I test Windows 95 with AMD K6 (500mhz) and i get system protection error (emulator: PCem) .

Does the actual limit was 500mhz~ or the AMD K6 was incompatible with Windows 95?

(wait, I'm actually asking about fastest cpu that could run Windows 95 (without system protection error) without any patches. Gonna start a new topic instead.)

AMD K6 debuted 2 years after Windows 95, but Microsoft released a patch which fixes the protection error you've mentioned.

I wonder where this limit was coming from? Was there kind of a hardcoded number in the code?

I'd say just stick to a 386 or 486, or a lower end Pentium.

For a 386 or lower-end 486 I would stick with Windows 3.1.
