Lenovo S145 Dual Channel 8GB or Single Channel 12GB which would be Better?

2020-09-22, 12:55 PM

I have lenovo S145 with 4GB RAM onboard. Now, I have asked this question to many people on internet. And, most of them recommend me to go with additional 4GB RAM for dual channel. My primary purpose to upgrade RAM is to play games, I also use MS office tools and yet another purpose is to deal with random app crashes and make my computer fast. 

I have heard the dual channel helps the most for APU users but as I have not tried any additional RAM on Ryzen APU yet, I am not sure about anything and very skeptical about youtube videos as most of them are overclocked. 

I am expecting an answer from experienced users.

Now one more question, how much vram or graphic memory will be if I upgrade to 4GB RAM?

It is well communicated that within desktop tower systems, Intel brand motherboards with Intel brand chipsets will use special memory access modes if memory cards are deployed in homogenous configuration.  All memory cards the same specifications.  These are called dual channel, quad channel, nowadays maybe even octo channel??


Laptops often do NOT conform to generic design standards used within desktop systems.


Find Lenovo Technical Support pages and inquire regarding support for channelized access to RAM.  For laptops there are often limited options for installing additional RAM.  For example, my machine has some RAM, 4GB,  permanently soldered, and only one additional slot to install new RAM.  For my machine, it is now almost impractical to find a RAM module as small as my soldered in RAM is, and then matching other specification details is also impractical to find.  However, I can install up to 16GB.  I presume 20GB of RAM will perform better than 8GB in dual channel mode.
