Q: Can my Mid2010 MacBook Pro Core 2 Duo use 16 GB RAM? Why does Apple say maximum 8 GB?
According to this StackExchange and the Mactracker app, my computer can support 16 GB RAM. If so, why does Apple state the maximum as 8 GB? Do you have a mid-2010 computer like mine upgraded to 16 GB using the latest Mac OS?
My problem is that the two 8 GB RAM chips I got from Newegg didn't 'click' when I tried inserting them (contrary to the instructions), and when trying to boot I got one beep together with the sleep light that repeated after some seconds, apparently indicating no RAM installed.
So it seems to me either I didn't push it in far enough (unlikely because I don't think it could be pushed in any farther), the chips don't work (I tried my best to frequently touch metal to avoid electrostatic discharge and avoid touching anything other than the sides with the semicircular notches), or the computer isn't recognizing them.
Does it matter that the sticker on this Newegg RAM and the sticker on my factory-installed Apple RAM are on opposite sides? Does the brand matter? Should I be concerned that there seems to be some sort of residue (as you might see when a sticker is removed) on a small part of the bottom left 'block' on the underside of each Newegg RAM chip? (This residue, together with the sticker being on the opposite side, makes me wonder whether a sticker was removed with a new one placed on it, as if this is used RAM being sold as new.) Is there any significance to the final number, '1066 MHz 151031', '1066 MHz 150930' on these Newegg RAM 'Warranty Void If Removed' stickers, or is it only for the factory (or seller) to identify the chip?
