Sorry to post such a basic question, but after searching, I'm getting conflicting info. My MacBook 4.1 has the 2.1 GHz processor and a Bus speed of 800 MHz. It currently has 667 MHz RAM installed, but I'd like to know if it will properly work with 800 MHz RAM (i.e. 2 x 2GB DDR2 800MHz PC2 6400)? Some sites say 667 and others say 800 MHz, but I thought the RAM should match the Bus speed. Any advice would be most appreciated.
MacBook 2.1 GHz, MacBook Pro 2.33 GHz, Mac OS X (10.5.7)
Hi dcains: From most reports on here, your McBook will NOT work with the incorrect spec RAM installed.
