I just got my logic board replace by apple and everything seems to be working perfectly...the info in "about this mac" is all correct, but when i run the tool on crucial.com and it scans your system to tell you what kind of ram you need it says this: Maximum Memory Capacity: N.A. Currently Installed Memory: 1024 MB Available Memory Slots: N.A. Number of Banks: N.A. Dual Channel Support: N.A. CPU Manufacturer: N.A. CPU Family: Intel Core 2 Duo 2.4 GHz CPU Speed: 2400 MHz FYI: i ran this tool before the logic board replacement and it worked fine and displayed all the correct info...also, i know what kind of RAM i need and have ordered it but I still would like to know what could be causing the problem here. Any ideas why this would happen??
