Wow.Just look at this,at the final of the page.
http://www.cpu-world.com/CPUs/K6-2/AMD-K6-2%2 … 6-2-400AHX.html
AMD K6-III/400AHX!
Also,it says this thing,which confuses me:
"This processor supports both 66 MHz (Socket 7) and 100 MHz (Super 7) bus frequences. For 66 MHz bus speed use 6x clock multiplier, for 100 MHz bus speed use 4x clock multiplier."
Alright,alright,but where i can get the 6x multiplier on a PCChips M577?

All newer K6-2 (CXT) and K6-III CPUs remap the 2x multiplier to 6x.

So this means even the AHX I have is a CXT?

Probably. I did some googling and found this:

If you can look at the chip it should have the number 26351 etched in the bottom left hand corner of the ceramic (top side near the square dot).

If it has this number, it should be CXT. You can also look this up with software, but I find the manual way to be easier since I don't have to insert, boot, run program, shutdown etc etc all over again.
Alternatively, you could simply check this by setting the fsb to 66Mhz (or lower) and setting the multi to 2x. If it remaps to 6x, then you have the CXT 😀

Just checked.It's a CXT as the number is 26351.

Another big advantage of the CXT core is that it has memory type range registers, which can be used to dramatically speed up graphics in DOS games.

Nice!Might give that a shot as soon as I repair my PCs to reflash the PCChips BIOS.If not,a Pentium II might be fine for DOS gaming or Windows experiments (Windows 98 hacks 😁 )
