ADDING TWO DIFFERENT RAMS

MonicaAcinom

Can u add a 4gb ram to a 16gb ram? Or is it required both have the same size? Does ist need to have the same frequency?

Hi,
You can add different size RAM but the speed and CL values should match, anyway, could you please post the laptop model name and the intended memory modules specs.

MonicaAcinom if you want to work in dual channel which its the best recommended for performance it has to be the same clock size/CL if you add for ex you have a 16gb 2666 and you add a 4gb 2400 you would not only not be in dual channel but also all the ram would work at the lowest clock this means the 16gb would only work at 2400 instead of 2666 anyway hope this helps

Hi,
No problem, we need to know the laptop model, actually you can check yourself using Crucial memory tool.
