Just curious about this. I noticed on crucial's site that it says the Mac Pro's maximum RAM is now 32 GB by using eight 4GB sticks. Apple's site still says that the maximum is 16 GB and so does the MacRumors guide. Does anyone know anything about this. If it turns out that 32 GB is supported, then WOW that's alot of memory. Maybe that's what the EFI firmware update was for.
