I just received and installed a 4gb kit from Crucial in my iMac 2.4GHz Intel Core 2 Duo. When both pieces were installed the machine would not boot. I took them out and swapped sides and the machine booted up and appears to be working fine. However, when I go to "About the Mac" it tells me I only have 3GB of 667 MHz DDR2 SDRAM. What about the other gig???? Thanks for any help.
