Hi I have a laptop motherboard that has a fixed 2.5x multiplier, I have gotten a socket 7 pin diagram once more and plan on hard wiring it to 3x.
I have a pentium 200mmx chip that has two "working" multipliers 2.5x and 3x
Anyway, is it possible to take 2.5x
BF0 - 0
BF1 - 0
and set it to 3x
BF0 - 1
BF1 - 0
by clipping the BF0 pin off this CPU?
Or do I have to run a wire to ground, I can't remember
Cheers
Ryan
Motherboard with FIXED 2.5x multiplier can I clip BF0 for 3x

Hey Ryan -
If I remember right, we went around about this for an M520 over at the PCChips Lottery...I think you need to pull it high if I remember correctly... Go try a search over there for what we did.
Good Luck!!

thanx, I will have to take a look, but...
That will involve clipping the pin enough so it doesn't contact the socket, then putting a wire to +3.3 I'm uncertain if I can do that.
The traces going to the socket are difficult to trace
and I haven't figured out what goes where yet, so modifying the inputs will be sketchy at best.

Search for resistors around which are connected to that pin in the socket. I guess that the mulitplier is hardwired using these resistors somewhere.
