Cyrix MII 300GP
MII 300GP (66 X3.5 3.9V) + TXpro m/b = failed
Max only accept 200 (66 X 3), suppose is 233 (66 X 3.5)
Cyrix MII 300 and 333 with TXpro boards does work. You need to update to the latest BIOS available. 3.5x66 and 3.0x83 types of processors work fine and stable even on the original M560, needless to say on the later M560TG, M565 and M575.
Just the BIOS will get the identification string wrong and always report a "6x86MX-PR266". The processor nevertheless runs at its rated 233 or 250 MHz speed.
I've done that several times by now, no problem there, not even in long-term stability.
What exactly didn't work in your setup? Maybe I can help.
I set jumper to 66 X 3.5 , but when reboot ,
the screen show CYRIX 266 only, suppose is showing 300, right..
when boot with 266, i failed to load win98..
So , now i boot with 233 (actual speed is 200, using norton systeminfo)
i would like to know how to solve it, update bios n how...
i want my MII 300 (actual speed 233) back
So for the details: What board is it? M560, 560TG, 565, or 575?
