Comment by Paul Collins (pi314aussie[at]yahoo.com):

I run five computers with this chip to this day. Comment: -please note, there is also a genuine -120 chip as well. I bought one at the time. It runs well at its rated 120MHz, but can't be overclocked. I have been able to overclock the 100 chips to run at 120, except for one only. It only runs at its rated 100.
As an extra comment, I have been able to overclock the Intel A80486-50 to 60MHz, and it runs fine. I tried at 66MHz, but only get a jiffy of life before no-go. I don't know whether the CPU or the M/Board chipset chips are the problem. I say this because the chipset chips are only 50MHz chips too. This is still inconclusive, because I have only ever tried one Intel -50 chip, and one m/board. Perhaps I should get hold of more Intel chips, and try them into multiple of my 486 m/boards?
