I want to upgrade my MacBook Pro(mid 2009) to the highest

"This appears to be your machine:

Apple MacBook Pro ""Core 2 Duo"" 2.26 13"" (SD/FW) Specs

Identifiers: Mid-2009 13"" - MB990LL/A - MacBookPro5,5 - A1278 - 2326*

It will take 8 GB of RAM

Here's the specs on it: http://www.everymac.com/systems/apple/ma...

Now the question becomes, ""how much RAM do I really need""? Besides the cost, you significantly reduce your battery life and increase heat. Here's a nice article on how to tell what you've used and if you need it: http://macintoshhowto.com/hardware/does-..."

yes it supports 8GB ram and plus u can change your HDD to a SSD then your mac is like a thunder!!

"Thanks for sharing information. I am a Mid, 2009, macbook pro, 5.5. I moved to Captain, with just a 2GB RAM, I am finding that the mac is not fast, It is so sad to see my buddy to underperform.

Hence, I am considering to increase RAM to 2 2GB s each. Can some one share light on it. Thanks in advance."

"Hi,

I did it and it is working great. Only problem is, one of the memory slots is dead, hence after putting 2x4gb RAM it only recognises 4gb. Both memories work well (I switched them around and the dead slot is always the same) Does anyone know if it is possible to put an 8gb memory in one slot instead of 2x4gb?

Thank you!"
