Inspiron 15-3543, RAM upgrade, power consumption

Well not just any. The following site is Crucial where you can match the memory to your system. The memory specs are DDR3L 1600. And you have 1 memory slot which will take a maximum of 8GB. So 1 8GB memory module.

So only DDR3L 1600 MHz models compatible? But the site you referred also show 1866 MHz models to be compatible. I'm confused.

Dell specs are up to 1600 Mhz. Even if you could use 1866 you would probably not see a difference between the two. In that instance the system would run 1866 at 1600.  Not confusing, Dell specifies 1600 so go with the memory specified for your system.

Thanks for the info :)

Crucial now has 16Gb 1600 single-slot SODIMM available. Will this work with this motherboard?

Most Likely YES

if you have i7 5500u .. it says it supports 16 GB

but the dell has not Verified it yet! 

borrow a ram from someone and check if it is working!  :Smile:

sir I m using Inspiron 3543 laptop I upgraded to SSD due to completely death of old hard disk I went to SSD now little bit ok but now I am using mechanical engineering software like CATIA hypermesh so. I need to update my ram also to 8gb .I m confused with single channel and dual channel if I buy dual channel 8 gb single what I'll happen can you elaborate it please

Dual channel requires two matched modules - which you can't have in this system.

Running CATIA software on a low-end budget system like this -- if it's even possible -- will require a vast amount of patience on your part.

Hi,

I am using Inspiron 3543 had default 4gb before upgraded to 8gb DDR3 which i am using from 3 years pic of the ram i am using plus the laptop slot pic is attached and its available on flipkart at around Rs 2000+.
