We have some old commercial systems that use 133 MHz Pentium CPUs. I understand that we should redesign them. But for now we need to procure additional CPUs. Intel no longer makes them, of course. But we found some online sources that sell them.
Here are my questions:
1. If we purchase these CPUs, is there a chance they are genuine but "recycled"? If so, what would be the risks in using these CPUs?
2. Is there a chance they are counterfeit? Is it possible, for example, a counterfeiter takes 75 MHz or 90 MHz Pentium CPUs and re-marks them as 133 MHz Pentiums? If so, could a 75 or 90 MHz Pentium work at 133 MHz? (I did some research on this. Apparently some of the original 75, 90, 100, and 120 MHz Pentiums used a 600 nm process and had a die area of 148 mm², whereas the 133 MHz Pentiums used a 350 nm process and had a die area of 91 mm². So I would think operating a 90 MHz Pentium at 133 MHz, for example, could cause it to overheat.)
Thank you!
