I've broken the top one now all I can have is 2Gb. I tried going back to 512MB so I could have 3GB. It shows its empty even though its really snug.
Looking at the 2 1Gb sticks I noticed they 4200u instead of 3200 like the one set I got before. Also the hole didn't line up right so that is how I broke the clips trying to force it in. I get a red light when I am trying to use the 512MB (x2).
If there is a way to get it so I can have 4 GB I would do it but since I am having trouble getting 3GB with the sticks that it came with I will just use 2GB and save up for G5 with more memory later then.
There was an order for the paired ram chips in size and speed to be plugged in to the PM.
The 4200 speed on a matched pair should clock down to 3200.
That doesn't make sense that because one clip is broken, the slot no longer works.
I have had two PM's with broken clips and the ram worked fine. Possibly, you broke the ram slot's connectors on the logic board.
But also make sure you really shove it into the slot snugly -- after you clean it out with a light solvent.
