I have a MacBook Pro purchased in 2010. It came with 160 GB hard drive and 2 GB RAM. I since installed a 960GB solid state hard drive and would like to increase RAM capacity as appears I need it for some applications. I've been led to believe that 8 GB RAM was maximum I could have in this computer so bought an 8 GB memory card.

Since purchasing the card I have learned that there are 2 cards in the computer which are 1 GB each. One set of instructions I found indicates that it is better to use 2 cards instead of one.

Now my question is do I return the 8 GB card and buy two 4 GB cards or will it be OK to buy a second 8 GB card and install them both. I have confirmed that the 8 GB card will fit in the computer.

Well, I have only worked on a handful of Mac's, but have a fair amount of PC experience. Generally, if your MacBook pro has an intel core 2 duo 2.4 GHZ or higher, it can address 16 GB of ram, even though Apple advertises 8 GB. Any Macbook Pro model 7,1 or higher, and any Mac Mini model 5,1 or higher should be able to use up to 16GB of RAM.

On a PC, the first thing is to verify the maximum amount of RAM the motherboard supports.
Then find out the maximum RAM speed and type the motherboard can handle. I.e. 1066 MHZ, 1333 MHZ, 1600 MHZ......... Yours might be able to take 1600 MHZ DDR3.
We find RAM speed to be as important as the amount of ram. You want to know if your motherboard supports interleaving, which can boost speed 8% or so.
Quality of the ram is critical for successful operation. You want error free RAM with no dead cells. Buy only name brand.

I decided to go for installing two 4GB RAM cards for total of 8 GB RAM. Couldn't find any 4 GB RAM cards in North Battleford at 5 locations I checked! Landed up at a computer store in Saskatoon and purchased them yesterday at a cost of $76 including taxes. Should be good enough for what I use my computer for.
