If you insist in trying to overclock a Cyrix CPU, you must tackle the issue
of heat....A better fan and probably a case fan would be needed. You could
check www.tomshardware.com for any reports of success, but they do not
encourage Cyrix CPUs to be overclocked....My advice is to get a surplus AMD
K-6 or any INTEL and overclock away.....Some PR200's were of very low
quality while some were quite good, this disparity in quality allows a very
low success rate of overclocking in market as a whole...

Good Luck,
David Olds

Hello All,

I have also been trying to overclock a Cyrix PR200 which my motherboard
(a P5V580-B with 580VPX chipset) will let me use 2 x 75mhz or 2½ x
66mhz. The problem comes when I try to run it at 2½ x 75mhz, The system
reports it as a Cyrix PR233 and boots OK and works in DOS mode but
Windows (95) won't load. It just freezes at the splash screen. I have
tried re-installing W95 but same problem persists.
By the way, I can't find a manual for my motherboard, which makes
changing jumper setting a real pain

Any suggestions ?

you cannot overclock Cyrix CPUS with any success...Also, they do not
allow
.5 settings...they are either 2x or 3x....
