Hi I have an early 2008 iMac with 1Gb of RAM. (Type = DDR2 SDRAM, 800 MHz). I'm currently running Snow Leopard. I would like to increase the RAM as much as I can, with a view to upgrading the o/s some time in the future. Your website has recommended a 4GB kit (2GBx2) DDR2 PC2-6400 Unbuffered NON-ECC 1.8V 256 Meg x 64 (CT3331888). Does this sound reasonable? Will it increase my RAM to 5GB, or does it replace my current 1GB? Any advice is welcome. Thanks.
