How many RAM sticks do I need for a Mac OS X 10.6. My systems processor is a 2.26 GHz Intel Core 2 Duo and uses 1066 MHz PC3-8500 DDR3 SDRAM memory
Your system only has two memory slots and your system has a limit of 8 GB of RAM (two x 4 Gb modules) Your system can support a newer OS than Snow Leopard OS-X 10.6 You can go all the way to El Capitan OS-X 10.11.x
