Can I put 6gb of ram in my imac?

RAM Types & Actual Maximum RAM Capacities

All 20-Inch and 24-Inch Aluminum iMac models have two RAM slots that are readily accessible via a small access panel on the underside of the display, but the type of SO-DIMMs as well as the actual maximum capacity varies.

Specifically, the "Mid-2007" (iMac7,1) models use 667 MHz PC2-5300 DDR2 SO-DIMMs (200-pin), the "Early 2008" (iMac8,1) models use 800 MHz PC2-6400 DDR2 SO-DIMMs (200-pin), and the "Early 2009" and "Mid-2009" (both iMac9,1) models use 1066 MHz PC3-8500 DDR3 SO-DIMMs (204-pin).

Officially, the "Mid-2007" and "Early 2008" models support a maximum of 4 GB of RAM, but they actually can support 6 GB. The "Early 2009" and "Mid-2009" models, however, both officially and unofficially support a maximum of 8 GB of RAM.

I have an early 2008 24" iMac with two sticks of memory, 2gb, each, in my two slots.

I'm confused, I've read conflicting reports, can I put 4gb of memory in one of my slots, and will it work, or will it just recognize it and not actually increase my RAM.

any information would be appreciated. if it's possible, do i put the 4gb in the first slot? and what brand/type of memory do i buy.

thanks for your help, i appreciate it!
