friend upgraded to 16GB ram and gave me his 2 x 4GB PC3-12800S sticks to put into my imac 2.66 core 2 duo with 2 x 2GB PC3-8500 sticks. I removed my 4GB and installed the 8GB. Seated very well (well as far as I can tell anyway)
Three beeps after power on.
reinstalled the old ram and runs fine.
is this ram not compatible with my old imac?
