Hi, I live in a very odd country where sometimes your needed hardware is everywhere and sometimes it becomes impossible to find it anywhere! SODIMM RAMs are in the same situation now. I have a Macbook(Early 2008, Penryn) 2.4 ghz with 2GB RAM. I want to take out its current memory modules and add two new 2GB matched modules. My problem is I cant find any quality 2GB SODIMM DDR2 667 RAMs in my country. Every shop I searched for Micron/Crucial and OCZ they had DDR2 800 modules! As it is written in macrumors guides Penryn Macbooks and MacBook Pros are known to be incompatible with most DDR2 800 modules. So here comes my questions: 1- Are there any penryn compatible DDR2 800 modules made by Micron, Crucial or OCZ? 2- Are there any other good quality brands for DDR2 667 modules that I should search for? Most kingstone modules are fake here and there is no OWC in my country.
