Why can't I use 2 new RAM modules together?

Hello, I want to change the RAM of my MacBook, but unless I do it with the combination of: old RAM + new RAM.

But it is not worth much because the old one is 2 GB, not 4 GB, so I would lose 2 GB. Someone to pass him by?

Answer this question I have this problem too

Is this a good question?

Well, it depends on which model you have!

The 13” MacBook 2.26 GHz Core 2 Duo Poly/Uni (Late 09) can only support a max of 8 GB of RAM.

The 13” MacBook 2.4 GHz Core 2 Duo (Mid 10) which can support 16 GB of RAM.

You do need to make sure you are using the correct RAM and you don’t damage the logic board socket or clips.

Is this:

And I bought this RAM:

#Aliexpress € 11,80 | A1278 A1286 A1181 A1342 Memoria RAM 4GB 8GB 16 GB y 1333 GB 1600 DDR3L Memoria Ram para Macbook Pro Memoria sdram

I think is compatible. Isn't?


@Juan Torralbo - While the Ali Express posting implies it is, What does the given SO-DIMM's tell you look at the stuck on label as well as look up the RAM chip part number.

Ifs also possible the SO-DIMM is correctly marked but the given module is defective.

Let's check your OS what is the system running? macOS Sierra (10.12.x)
