Well, tis safer to read the info printed on the processor and search the web
site of the company making it for the model number.
But if you have a blank one and a motherboard you can risk...
There are two voltages to worry about and they are for the IO pins on the
processor and the core voltage.--too large a difference in these can be as
deadly as way way too high a voltage. SO, since the I/O pins are the higher
voltage, start with the lowest voltage for the IO pins and the highest for the
core--like 3.3 for everything--if it works, you most likely have a Pentium
between 75 and 150 MHz....
Then work DOWN the voltages for the core--if none of that works, then use the
3.52 for the IO pins and the core and again work down the core voltages.
At some settings the processor will hang, at some it will rise rapidly in
temp--put a digital thermometer on it while you do this, or don't do it. At
some it will work intermittently at some it will work mostly and at one or
perhaps 2 or 3 it will work well. One of the overclocking tricks is to "up
the electromotive pressure on the processor" (raise the operating
voltage)... I put a K6-266 up to 285 on a 95 bus by kicking the IO pins from
3.3 to 3.52 and it runs great. It was 4x on a 66 bus for 266 and now it is 3x
on a 95 bus for about a 30% improvement in speed.
HOWEVER, it is far better to use the search tools at your disposal for
appropriate information in identifying and runing compuiter components than it
is to decrease your cash supply for the purpose of increasing the world's junk
supply.
