Will adding a 4GB 1333MHz DDR3 ECC SDRAM and a 2GB 1333MHz DDR3 ECC SDRAM work and give me 6GB in the same Macbook Pro?

I am planning on buying a Refurbished MacBook Pro 2.4GHz Dual-core Intel i5, the comes with 4GB (2 x 2GB) of 1333MHz DDR3 SDRAM but I want to boost the RAM by removing one of the 2GB and adding a 4GB. Will this my new configuration work and will all the RAM (6GB) be available for my applications (Specifically Cinema4D and HD Video Editing with Premier).
Thanks

  • I believe that they work, just no where near as well as they do if you pair them correctly. something like it lowers the bit-rate that the RAM works on, so that they can both be used simultaniously.

    I am doing some more intensive applications like photoshop and illustrator, and 4GB RAM isnt enough in many circumstances.
    My Imac12,1(21.5 inch mid 2011) came with 2x2GB, and i will add 2x4GB

    ALLWAYS PAIR THE RAM. THEY CAN BE DIFFERENT GB SIZES AS LONG AS THEY HAVE ANOTHER OF THE SAME.
    Your macbook has only two slots, so you either dont upgrade or upgrade both
