Ok. So my mother has an early 2008 iMac (24", 2GB RAM 800MHz DDR2, 2.8GHz, 8800Gs) and needs some more memory. Apple Support states that the maximum supported memory is 4GB. However, I know that some machines can utilize more memory than the stated maximum, while others have a hard limit. Can I put in 8GB of RAM? Will it all be utilized, or would I only have access to 4GB even with 8GB in? Thanks!
