Is unlocking possible??????

[LongJohn1980]

I've done a little research on p200's and found out that early versions of the P200MMX is multiplier locked at (3.0). Is there any way possible to unlock this processor? I've been looking for info on unlocking it all night but no such luck /forum/frown.gif . Any help would be appreciated.

Not really. To lock the 200MMX all they did was effectively not connect one of the two pins that decided the multiplier. To unlock it you would need to open up the chip package and reconnect that pin on the package to the correct microscopic pad on the CPU die. Then, put the package back together. Unless you have some serious equipment for doing very fine solder work, a clean room, and very steady hands, I would not recommend it.

I've had my 200MMX running at 250 MHz (2.5x100) for several months now. Didn't do anything but plug it in and go. Tyan S1590S with 100 MHz RAM.
