There is an article on anandtech that describes how to lower the default processor multiplier with a pencil. Some of you have probably heard that this was done to bypass a bug where the mobo did not want to use a lower multiplier during first boot. If you just wanted to lower the multiplier, it was enough to change the connections on the L6 bridge. But I want to do something different.
I have a GA-7ZXR Rev 1.0 board where it is not possible to change the multiplier via jumpers or bios. The board has a via chipset with FSB100
I also have an A1200AMS3C CPU which has FSB133. Since the board has FSB100 - the CPU runs at a frequency of 900MHz (100x9). What to do to INCREASE the multiplier?
This article describes the connections on the L6 bridge corresponding to specific multipliers.

In order for the A1200AMS3C processor work on a board with FSB100 at a frequency of 1200MHz, I need a x12 multiplier. The problem is that when I connect the appropriate L6 bridges, nothing happens. I tried several times. I tried lowering the multiplier once and then the PC didn`t booted up, so I think my pencil is conductive, I did it quite carefully.
I found another old topic that says that when increasing the multiplier, apart from modifying the L6 bridge, you also need to modify other bridges.
1. Which one?
2. How?
I haven't found any information in old threads that talks about this. Maybe someone will know?
