Help in mixing memory. 4 GB RAM + 8 GB RAM DDR4

[Nehemiah Ancheta]

Hi i'm upgrading my laptop prebuilt 4 GB RAM and i will add extra 8 GB RAM and i have only 2 ram slots in my laptop. If it is okay to upgrade then my laptop will have dual channel? Sorry for my english.

Yes, you can run it on dual channel.
But if you have 32 bit os, then it will not.

If you are mixing modules , it may or may not run , won't know till you try it.

Be aware that for dual-channel to work, both RAM modules must be the same capacity (ie 2 x 2GB modules or 2 x 4GB modules etc).

If the two modules are different capacities they will still work, the total RAM will be correct but they'll only be operating in single channel mode.

Actually no, unless it's an old laptop(pre 2010, or a very cheaply implemented BIOS) , and this is a current (using DDR4, if you have 4GB and add an 8GB, then Flex mode should enable and you will have 8GB (4GB from each stick) running in dual channel mode and the odd 4GB from the 8GB stick will be in single channel mode
