Hi Jesse,

I have Inspiron 15 5559 (6th Gen i3 processes) with 4 GB DDR3 RAM currently installed in it. Can I install another 8 GB (crucial) DDR3 RAM in it or 4 GB variant due to earlier installed RAM?


Yes, it will definitely work.  The only thing is that when you mix the capacities of your RAM modules like that, the system runs in mixed channel mode.  This isn't a bad thing, it's just not best for performance.  Keeping the capacities the same (e.g. 2x4GB, 2x8GB) will allow the system to run in dual-channel mode.  Not really a big deal unless you're running apps when low latency is critical.


Is it safe to use CL9 memory instead of CL11? Would there be a performance advantage?


Ask the manufacturer of the RAM about compatibility.  No, there's no performance advantage.


Thanks. I was looking at G.Skill but found a better value CL11 from Timetec, installed and passed the full test.


 Hi  @DELL-Jesse L

I have the same  Inspiron 15/5559 laptop.
When I open System Information in Windows I can see the following:

" Installed Physical Memory (RAM) = 8.00GB   "

Does this mean that my 2 DIMM connectors are populated with 2x4GB SODIMM ?

I've been having some issues with the ram so I want to get the highest memory possible. This would be 2x16GB SODIMM for a total of 32 GB correct ?  But in the spec sheet you posted the maximum memory is 16GB. Is the maximum 16GB per DIMM connector ? or in total ? 

In other words am I going to have problems installing 2x16GB SODIMM in a Inspiron 15/5559 laptop ?





2X8 is the maximum supported by this system.

It may or may not be possible to use 2X16, but it's not a supported configuration, so if you decide to try -- be sore you understand your memory vendor's restocking fee/shipping charges, in case 32 does not work and you need to return/exchange it.
