Mike, I would verify that you are using all the same speed memory and same latency. Mixing different chips could cause problems. You might also want to clean the slots and test each stick individually using AHD (Apple Hardware Diagnosis) if you don't have the CD that came with the computer you can download the image from Apple Support site (sorry don't have the link for this). Once you test individually try 2 at a time and switch the 2 that you are testing.

It's model M8493 running a 933mhz processor. I have tried to max out the ram to 1.5GB but when I put the final 512MB chipset in it causes programs to freeze or just quit midstream (like Firefox, Safari), or the machine to freeze up altogether. If I put a smaller size chip in it runs fine (I have an old 128MB one that used to run in it). The machine recognizes the 1.5GB. I have tried rotating the chipsets in the memory slots, made sure they are seated properly, and even returned the most recent one purchased and gotten a replacement and the machine still has the same problems. I don't know if there is something I am missing or what. If anyone has any ideas as to what the problem is or how to solve it please let me know.
