What RAM to choose for a laptop under Android Studio?

Question

laptops

Good evening everyone. Last year I bought such a laptop model to study programming and now there is a need to increase the RAM to speed up the emulators. The laptop has 4 GB of soldered memory + 2 GB of flash. When choosing a new chip, I want to ask the following questions:
1) On i3 7100u processors, does it make sense to put a chip in 8gb so that the total memory is 12 gb? Or this processor will not be able to use all the RAM?
2) According to the description of DDR4 2133 MHz RAM. Does this mean that if, for example, I put a memory with a different frequency, then it will not work?
3) Recommend RAM manufacturers.

Answer 1

1) To find out what the Intel processor supports, visit ark.intel.com. Actually, if you just google the processor model, it will be one of the first on the list. We go in, we see the amount of supported memory at 32GB, and thus the first question has disappeared
2) Now it is usually unprofitable to buy DDR4 for 2133 - 2400 costs the same, and in the future it will be of great value. If you put memory with a frequency higher than the supported one, it will simply work at the frequency that other components can. So even if you buy 2400 or faster, it will just run at 2133MHz. Actually, many stores allow you to immediately check the memory for compatibility with a laptop on the spot, so you buy it, they put it on you right there, if it suddenly doesn’t work, you change it on the spot.
3) You just have a regular laptop and not the fastest memory today, so buy any. If you needed memory for overclocking, or there were some other special requirements, then you would have to choose. And DDR4 2133 is already the simplest DDR4 memory on the market, at 2400 MHz it is the most massive, in short, everyone makes it plus or minus the same. Just buy with minimal timings, less timings are better, but one thing they will show up under those on which the soldered memory works.
