How to choose a memory for a laptop

Does the system hang if the browser has 10 or more tabs open? It is impossible to work in Photoshop, since the computer is clearly unable to cope with the load from the program? Instead of enjoying the long-awaited cool game, you only get to watch the "stuck" slideshow from video fragments on the screen when you start it? And the main question: what is wrong? After all, before the problems with the operation of your device was not observed. Most likely it is in RAM.

What affects the amount of RAM

RAM is a random access memory. This is the internal element of your computer, which allows it to be multitask and at the same time quickly cope with all processes. To explain its purpose and principle of operation, it suffices to note that it represents a kind of buffer for storing information used at a particular moment. It is needed so that when performing a specific task, the system does not scan all the data contained in the long-term memory, but can immediately turn to specific ones.

It turns out that the larger the volume of this buffer, the more complex the process can be implemented in the shortest possible time. That is why if you have situations like those listed at the beginning of this article, you should think about replacing the entire RAM (unless it is soldered to the main board) or about adding more to the free slots.

Reference! A slot is a place (connector) that is intended for connecting new RAM modules.

To accurately verify the need to purchase an additional bracket (boards with installed RAM chipsets), we collect information about the computer. For this:

• run some program (even a few are better);
• at the same time press the keys "Ctrl", "Alt", "delete" and in the opened list select "Task Manager";
• Select the "Performance" section.
• check how memory is loaded and how the processor works.

If it is involved at 80% and above, then add RAM will not hurt.

How to choose the optimal size of RAM for a laptop

First you need to decide for what purpose the computer will be used?

If you need it for regular surfing on the Internet, for music, movies and performing some simple tasks (for example, working in Microsoft Word), then you will hardly need more than 6 GB of RAM. 8-12 GB will be chosen by amateurs to simultaneously run several programs or leave 100 open tabs in the browser. And the largest option - 16 GB (sometimes even 32 GB) - is used by owners of powerful machines who regularly launch time-consuming programs or games with a complex interface and a rich storyline.

Important! With a 32-bit OS more than 3 GB of RAM you can not have. Therefore, before expanding the memory, it is worthwhile to clarify the bit depth of your system and, perhaps, even change it to 64-Bit.

The logical way is to look at the information on the official website of the manufacturer of your laptop.

However, there is a second:

• from the site //www.aida64.com/downloads download a program that collects information about the configuration of the computer;
• after installation, run it;
• double click on the "Motherboard";

• go to the "Chipset" section and find "Maximum memory capacity" in the list.

Reference! It is believed that 1 GB should be allocated to one logical core of the processor. But look at the exact maximum amount of reliable.

What RAM to choose for a laptop

Volume is not the only option to choose. It is also worth paying attention to generation, form factor, frequency and timings. We understand in order:

1. Form Factor is a standard bar size. It is required to understand that RAM intended for a stationary computer (DIMM) cannot be put on a laptop, and vice versa. It is worth mentioning that the form factor of modules for installation on a laptop is SO-DIMM.
2. Frequency. First, you should consider only those models of RAM that, by this criterion, correspond to the processor and the motherboard. Secondly, remember, if you install two chipsets with different indicators, then both will work at a lower value.
3. Timings are so-called delays in work. Therefore, it is logical to choose chips with the lowest timings (but not to the detriment of frequency).
4. The generation must match the already installed RAM on your computer. The fact is that each system is capable of supporting only one specific generation (in the connectors the keys for placing the bar are even respected).

Given all this, you can purchase a fee that will really increase productivity at times.

Generations of RAM

Today we can distinguish three main ones: DDR2, DDR3 and DDR4.

1. The first option is almost out of circulation. Perhaps it can still be found on some very old devices. But now you can not find a single model, which would fit DDR2. Such modules were released in 2003, and works from 400-1066 MHz.
2. The second number is already noteworthy. In the new powerful laptops, he certainly will not meet, but in the past has been distributed. Year of development: 2007. Frequency: 800-2133 MHz. Also adds the ability to provide lower power consumption.
3. Finally, the third option - the most used in the present strap. Developed in 2014 and is able to support the work of the latest devices. The frequency is about 1600-3200 MHz.

Now you know everything you need to choose the right strap and increase the performance of your laptop. You can, without doubt, and knowingly go to the store for shopping.
