If I take PC133 RAM from my eMac and put it into an older eMac that came with PC100 memory, should it work? Once I tried putting just 1 stick in, and the computer booted up but it didn't recognize the RAM. If I took out all the PC100 and put in 2 sticks (512 + 256) of PC133, then might it work? The newer of the two eMacs dropped dead, so I'm trying to get the older one running well. There's no point in buying more RAM for such an olde computer, though.
