What is the best way to increase RAM?

Question

Iron

Hello. My PC has two 2GB 1333MHz DDR3 sticks. Now there is a need to increase the memory, in connection with which the questions arose:

1. What is better to buy: one 4GB or two 2GB?
   
2. Search also for 1333MHz or better 1600MHz?
   
3. How to determine which one I need: DDR3 or DDR3L? Or are they interchangeable?
   
4. While I was looking for prices, I noticed that long DIMM is written on some slats. What does it mean? It is important?
   
5. What else should you pay attention to when buying?
   

Motherboard - ASUS P7P55D
Processor - Intel(R) Core(TM) i3 CPU 540 @ 3.07GHz, 3067MHz, cores: 2, logical processors: 4

What is better to buy: one 4GB or two 2GB?

2x8gb

Answer 2

First of all, you need to pay attention to the motherboard model, and read which memory bars it supports. This will solve the question about 1333 or 1600, as well as DDR3 or DDR3L
Also, this can solve the question of how many sticks you need to buy - do you have two more slots for two sticks of 2 GB each, or do you have only two slots, and then it's not clear how you want "buy in addition" to what is already there.
When buying, it is advisable to pay attention to the manufacturer and buy trusted brands and not noname.
LONG Dimm is a common desktop memory. Usually the word long is omitted. And laptops use shortened sodimm strips.

Answer 3

1 Well, you asked me. 2 + 2 will be cheaper and a bit faster. But if you miss 8 GB of RAM and you want to buy more RAM, you will have to throw out the 2 GB sticks. So myself.
2 1600 it makes no sense to put it, but you don’t need to run for 1333 as a specialist for the price, see shorter.
5 See that the RAM is not AMD ONLY and that's all.

Answer 4

1. As Nekto_Habr quite rightly said - two to eight. There are only four slots on the mother, to occupy them with nonsense that you won’t know where to put in six months - why? If you lived in my city - I would give 2x2Gb for free - there are six things lying around at home, nowhere to go.
2. Don't care. All the same, the memory runs at the frequency of the slowest bar. If the mother supports 1600 - theoretically you can take it - for the future
