Hello!
I've put together a win98se + Cyrix MediaGx 200GP.
Cpu-z gives a variable FSB, from 20.xx to 33.44mhz, lowering the cpu frequency with a fixed 6x multiplier.
Just a mistake or the chipset did adjust the fsb? Cx5520 chipset based mobo (st-mgxm).
Just putting the thing together was a royal pain, as it really hates pci add-on cards for usb.
Freezes a lot and works well only when everything is plugged in at start.
I chose the "hurt me plenty" level and it did  |

FSB should be fixed on 33.33 MHz for 200GP (and all other speed grades except 180).
There is special version of CPU-Z for old CPUs,

If it does not work correctly you can report it in that thread. |

Thanks.
Yes, rated fsb isn't fixed on 33mhz.
Is there any other app to test this system? |

Vogons is one of the best sites for info about vintage hardware. One of the few sites I follow daily (in particular, Marvin).
