Hi, guys! Help me please.
I have Toshiba Satellite L850-C9K. It was 6 Gb Ram (2 Gb Samsung DDR3 1333 MHz 64 bit + 4 Gb Samsung DDR3 1600 MHz 64 bit). So they both worked on 1333 MHz. Yesterday I've bought 8 Gb Kingston DDR3 1600 MHz 64 bit to remove 2 Gb Samsung. But, I don't know why, 8 Gb Kingston and 4 Gb Samsung don't work together. It is 12 RAM, but only 8 Gb available... Help me please, how to make them work together?

Did you try ensuring that both modules are the same brand? Might not matter but ...

Your laptop can handle up to 16GB (2x8GB) but mixing memory cards is never a good idea since there is generally compatibility issues. Did you verify that the Kingston card you bought was compatible with your computer?  If so and it is, then I suggest you buy another Kingston like the one you have and remove all the Samsung chips.

The answer is in using Windows 7 Home Basic, which can't work with more than 8GB. I upgaded it up to windows 10 and now it works.
