I have my ACER Aspire 5820TG - 433G32Mn and want to upgrade RAM memory.

Currently it has the following components:

CPU: Intel Core i5 430M

Mainboard: Acer ZR7B

RAM (3GB): 2048MB DDR3 PC3-10700 (667MHz) Samsung M471B5673FH0-CH9 1024MB DDR3 PC3-10700 (667MHz) Elpida EBJ10UE8BDS0-DJ-F

I replaced HDD to SSD, and want to also upgrade the RAM memory (3GB is pretty low, when using for example Android Studio, etc). I have some doubts, what parameters are needed to successfully upgrade it. As I see, current (original) RAM is 1333MHz, and 7-7-7-20 (?). But on the intel site i see that it works with 800/1066. So it is probably underclocked.

Which RAM will suit me? What is important? Timings must be the same? What else?

I want to upgrade it to 6GB (leave current 2GB and buy 4GB, or buy 2x4GB, as I guess, that I can use only 2 slots)

Here are some pictures from CPU-Z:

According to your CPU specifications, as it is also on intel's website (and as you mentioned), your laptop' CPU can support DDR3-800/1066. In this case I would recommend two memory modules, since it supports dual channel memory. And for a better performance, I would also recommend two modules with the same memory and clock speed. In this case it would be 2x4GB memory sticks. In case if the manufacturer has "unlocked" the motherboard for higher speeds (which I doubt), you can check with a tool like HWiNFO, what is the current memory clock for each RAM module. (On the left side, under "Memory"). If they are running at 1333MHz as your original RAM, then go on and buy a pair with that speed, otherwise buy a pair of 1066MHz.
