Remember Overdrive chips?

[Sarlok]

What's the deal with overdrive chips? I can remember seeig them everywhere when I had my 486, and I was wondering how they worked.
I'm likely to be picking up an AMD 486 75mhz cpu soon and was curious if I could overclock the CPU and use an overdrive chip as well? Or do they only work on some frequencies/voltages/chips?

Thanks.

I'm not too sure about the overdrive chips, but I know some of the "upgrade" processors are simply clock doubled. Hence, if you bought a Cyrix 386-to-486 33 mhz processor, you really are buying a 386 DX2 66 Mhz processor. Of course that's a really old example. I'm not sure how to overclock older processors, but I believe you may have to replace a clock generator to do it.

They upgraded your CPU to the next level without upgrading any other components, therfore giving you (in this case) a pentium that does not perform as well as a pentium, but does run faster than the 486, and has the features of a pentium. You are probably better off getting a socket 7 mainboard and a 200 for the price though.
