How to choose RAM (memory)?

I suggest getting CPU-Z to check you current configuration. The main thing you'd want to know is whether you have two 4GB SODIMMs installed, or one 8 GB. https://www.cpuid.com/softwares/cpu-z.html

As the initial configuration was 4GB, it could be either way. That determines what SODIMMs you'd have to buy to go to 16 GB. (If you have a single 8GB one in place, adding another would do it. If you have 2 X 4GB, you need to buy two 8 GB, or a single 16 GB.)

I don't know what RAM to recommend for Japan. I've had good luck with Corsair, Gskill, and Crucial (Micron), but there are other good makes. My main desktop is running a couple of Corsair DDR4 DIMMs at the moment. I'm pleased with them, but they have LEDs, which I find slightly embarrassing.

Hi, thank you very much for the detailed reply.
You wrote " what SODIMMs you'd have to buy" Yet, I did not install cpu-z rather attaching an image shot taken while Crucial website checked the memory. You can find some information on the left side. In the meantime I will try to learn what does this mean what SODIMMs you'd have to buy


Thank you once again for help.

If you can't find the same RAM that is installed in your laptop, you can buy a similarly-specced RAM doesn't matter which brand it is

As bobkn said, use cpu-z to find your current RAM type, then try to buy the same module for second slot. If possible, do not mix different types of ram modules.

I suggested CPU-Z because it can tell you whether you have two 4GB SODIMMs installed in your laptop, or a single 8GB one. I think that the Crucial web site gives you information about what is compatible with the laptop, not what is installed in it.

Crucial is saying 4 GB in one slot. Check by looking in Laptop and noting labelling, and sockets.

Various ACER models are different in countries/markets, looking is the best way to find out to make sure.

Therefore for 8 GB, another 1 x 4 GB to the spec indicated. DDR3L-1600 SODIMM PC3L-12800 unbuffered. CL 11 1.35v.
For 16 GB, 2 x 8 GB (kit) and remove the current one.

Those 2 options should retain 2 channel operation, put 1 x 8 GB in it will run as single channel 12 GB.

My apologies. Looking back at your first post, I didn't notice that your existing RAM is 4GB. I have no idea why I thought you had 8.

You have one SODIMM. You can add an 8GB one, for a total of 12GB.

It would be less expensive to add a second 4GB SODIMM, giving you 8GB total. That would probably also give you dual-channel operation, although you may not notice the performance increase outside of benchmarks.

Here's a link to some Kingston memory that may match what you have: https://www.kingston.com/us/memory/s...re&Model=98734
