Modding PC100/133 SDRAM

NO it won't.....in fact, putting faster ram in a slower slot may work just fine (to a point), but is essentially a waste of the ram....
ie using PC-133 in a B&W G3, which is spec'd for PC-100 or putting PC-2700 in a system spec'd for PC-2100..... Yea it works, but the ram just DOWNclocks itself to run at the lower speed

You're absolutely right, because the PC100 RAM slots will only let PC133's run at 100MHz instead of 133MHz, but I'm trying to find a way to MOD the G4 SAWTOOTH NOT Gigabit Ethernet (also known as Medusa2).
Ok but whats a GE got to do with this ? If you want to mod the machine itself, the only way I could think of is to replace the memory controller on the mobo, which would be relatively easy except for one thing: you'd have to find a faster, compatible one first.
And since apple isn't in the habit of selling repair parts to just anyone, that would indeed be a difficult task
So you want to mod the memory bus clock on a Sawtooth motherboard (not mod PC100/133 RAM) correct?
Not going to happen. There are no BIOS settings to change or jumpers to move for clock speed. Unless you're going to get into cutting traces and replacing components on the mobo, which would be foolishness incarnate.

Actually it is possible to change the FSB with a DIP switch without damaging it, depending on how you set the clock speed, but I'm trying to find a DIFFERENT, more unique way to mod RAM, instead of changing speeds.
Like what? There really is no productive mod for memory other than overclocking it, and even that is often either not possible or too risky for the small potential gain.
It is NOT that risky to put a DIP switch in the motherboard, and configure the jumpers correctly. You just need to be careful and have some soldering skills.

GE RAM mods are different, since its the REV2 motherboard.
