Macbook pro mid 2009 problem with memory

[LUCAS REVAINERA]

Macbook pro mid 2009 does not recognize 16gb ram when before I recognized them, days ago I had to do a maintenance on my mac, I had to disarm it and re-move the reader and clean the cooler, when I armed it again I only recognized 8g, 4gb of each slot or socalo, now I do not know if it was long before going from yosemite to the captain, will there be something to configure? Thank you very much, I would appreciate the help

According to Mactracker, all 2009 model MacBook Pro machines can only recognize and use 8GB of memory. Are you sure you installed 16GB of memory? That would mean you would have had to install 2 x 8GB modules which = 16GB.

Hello thank you for answering my question, if i'm really safe q i had installed 16 gb of memory beautiful 2 memories of 8gb in each socalo .... What calls me the attention is q now only recognizes each of the memory 4 gb. Now i am going down the yosemite and see if you get to accept me all

Well, give it a try and let us know. But, like I said above, your MacBook Pro can only recognize and use 8GB. (2 x 4GB modules)

Even if something on that mid 2009 Macbook pro was causing it to erroneously display that 16GB of RAM was installed, there's no way in hades that it's CPU or any other chips could actually access or use it on that MBPro model.

So maybe it's either a later model that does or something got disconnected during that recent maintenance project.

The mid-2010 MBPros could sure work with 16GB RAM, max.

I was thinking the same thing - that perhaps the OP had a 2010 model instead of a 2009. But he clearly stated it was a mid 2009 model.

As did the guy pulled over for speeding when he told the cop he was driving well under the speed limit. ;D
