The first thing to check is installation technique. When you push the SODIMMs into the socket, they go in about one inch, and stop. You then have to push fairly hard with both thumbs to make them go in 1/8" more to make contact with the pins. It could be that one socket is tighter than the other, (or one RAM module is thicker than the other) and you are not getting the RAM fully inserted. This accounts for about 50% of intel iMac and MacBook memory problems.I have a memory problem with my Imac 1.83ghz.
Every time I put 2 x 1gig it won't start and the light flash. somebody know what is the problem?
Is work with 1gig, but when I put both ... don't start.
