overclocking a 040/25
« on: October 16, 2007, 09:34:36 PM »
I have a PPC with a 040 cpu running at 25 MHz.
On the ppc there is a multiplier that is currently set to 0.5 hence the 25 MHz... If i add a LARGE sink and fan to it. would it be safe to run the 040 at 50Mhz?

It would be much safer to get your board upgraded to an 060


Would a "socket 7" socket work?
Have some old pentium boards laying around somewhere...

you would destroy a 68060 if you put one in

After reading a lot about it, on the PPC board there is ways to select the voltage between 5 and 3.3V. And to change the multiplyer from 0.5 to 1.
So the BPPC card is ready for conversion to 060. And it will start up with the 060 instead of the 040. But just enough to flash the firmware to 060 content.

I have done a lot of research on that. But I have no clue to where I can get the parts needed... Mainly the 060 though...
BTW the 060 MUST be of a MC 060, not any ec or lc... not even if they clock well...!

The 68060 will fit in the same socket where your 68040 is now

I have no socket, it is soldered to the board...
