Losing RAM when switching from Vista to SL
I recently increased my RAM to 16GB (8 x 2GB) and have noticed that there is a recurrent error in RAM detection when switching back from my Vista partition to SL. I know that Vista can't detect 16GB, but I don't understand why OSX fails to detect it when I boot back to SL. The system profiler either fails to detect any RAM in a paired slot, or detects 1GB instead of 2. This can be fixed by reseating the RAM, but only occurs when booting back from Vista. Any thoughts?
