It came to me as a surprise that this dtk pam-0057i-e0 could run one of my ppga p55c pentium 1 233mmx at 133mhz. I usually run my p1-233mmx at 166mhz as it allow me to plug the cpu heatsink fan on a 5v rail which make them silent and 166mhz is fast enough already. This computer board could run the cpu at 133 using a multiplier of 2.0 instead of 2.5. But when I set the multiplier at 1.5 it bring back the cpu to 166mhz...
On paper this sound great, but it would also be an over-voltage because I read the 133mhz is supposed to run it's core at 2.45v (as it was a mobile declination I guess). Also the ppga p55c was never designed to run below 166mhz. The only step below 2.8v this motherboard can go is 2.2v and there the computer dont even post beep.
Is this a challenge for the stability or security of the cpu to run it at 133mhz ?
