Can you help me ? (RAM association)

[Pringbulbs]

Hi everyone, I'm new on this forum and I'm French, excuse me for English mistakes.

 

Here's my problem,

I've my Gaming Laptop for 3 years and it gets a bit old and slow down in front of new games. When I play games and videos (on Chrome) both in time, my PC suffer a bit. 

I've only 8 GB of DDR3L 800 MHz memory and my problem of perfomences should be there. I've looked up to change my RAM and manufacturers say I can replace a part of my RAM. My 8 GB DDR3L memory is separated in : one 4 GB part sodered part and another that I can replace.

 

So can I use 8 GB 1600 MHz (or 1866 MHz) DDR3L memory with my 4 GB 800 MHz sodered RAM because it's DualChannel.

I drop some screeshots of CPU-Z.

 

My PC :

Intel Core i5 4200H @ 2.80 GHz ; Socket 1364 BGA

ASUSTeK Computer Inc. / X550JX

8 GB DDR3L 800 MHz DualChannel (4 GB PC3-12800 // Samsung M471B5173EB0-YK0)

Intel HD Graphics 4600 // NVIDIA GeForce GTX 950m 2 GB

Yes you can replace the one stick but the internet tells me that the highest ur cpu allows is 1600MHz.

Also since there is 4gb u cant change at 800MHz both channels will work at 800MHz(please correct me if im wrong).

But for watching videos in chrome i dooubt its the ram, no?

I've heard that Chrome likes to eat your memory... and because I can't change anything else (except HDD), I've to try it at once.

Is the video experience also bad in firefox?

An SSD might be a better buy then new ram, unless you have a good place to get it second hand?

Firefox doesn't want to run anymore on my PC, it takes one thousand years to launch it.

And for SSD, my PC only have one slot of SATA III (no M.2 obviously [2015]), and I've already plan to buy a 1 TB HDD @ 7200 rpm (faster than my 5400 rpm one). [Also because SSDs are way more expensive than HDDs.]

Here is what a would do:

Since you are planning on getting a new HDD.

A good 1TB HDD goes for around €40.

I would say double it and get an external usb3.0 1TB drive for €50 and an internal 120GB SSD for €30.

Thanks for the advice but disk mastering is not my cup of tea anyway (it's already painful for me to backup my old PC).

dual channel when both sticks have space, single channel when one does and the other doesn;t, like mixing up memory stick capacity
