Q: Upgrading to one 8gb ram slot and leaving a preexisting 2gb slot.

Is it ok to have 10gb that way? Will it have a negative impact on the performance instead of 2 x 4gb? I have a 2011 13" 2.30hz i5 MacBook Pro.

 

Grateful for any help.

    Hello lighturfire,

    I see you are looking to upgrade the RAM in your MacBook Pro and are looking for the best performance. The following article provides the recommended upgrade for your computer. 

                                                                                        
    MacBook Pro (13-inch, Late 2011) and MacBook Pro (13-inch, Early 2011)
    Number of memory slots2
    Base memory4 GB
    Maximum memory8 GB
    Memory card specifications- Double Data Rate Small Outline Dual Inline Memory Module (DDR3) format
       - 67.6mm x 30mm (1.18 inch)
       - 2 GB or 4 GB
       - 204-pin
       - PC3-10600 DDR3 1333 MHz type RAM
    Additional notesFor best performance, fill both memory slots, installing an equal memory module in each slot.

     

    Note the last comment from Additional notes: "For best performance, fill both memory slots, installing an equal memory module in each slot."
