Most users are of the opinion that it is more profitable to assemble a computer with their own hands than to purchase a whole system unit. And they are definitely right. The abundance of accessories for personal computers will allow you to assemble a "car" for taste and color, for any purpose, but everything is not as simple as it might seem at first. The choice of parts must be approached wisely. In this article, we'll look at how to pick up the RAM for a laptop and a desktop computer.

How to choose the RAM for the computer? Such a question does not suffer haste. First, we will get acquainted with the device itself, in order to understand what is at stake.
RAM is used to store a variety of data and commands that are important and necessary for the operating system to work. The amount of memory must necessarily be enough to operate the device, otherwise - there is a risk of encountering "brakes" of the system, if it ever works.
The board itself is called a "memory module," and a simple language is a bar. The bar that is used for laptops is practically no different from the component for a desktop computer, so you can follow the following recommendations in both cases.
Now we can proceed to the basic selection criteria.
to the contents ↑What do I need to know?
First you need to consider the model of the motherboard and processor. The memory module itself is attached straight to the motherboard, which can always support only certain types of RAM.We conclude that the processor, motherboard and RAM are connected to each other.
Important! In order to avoid incompatibilities, the first thing to do is to go to the official website of the manufacturer and find out the supported memory types.
After these steps, you can go to the technical specifications of the bar.

Today the most relevant are the DDR-modules. They can be classified according to the following parameters:
- DDR SDRAM."Old man" for his fellow men. It has a very small clock frequency, which is approximately 400 mHz.
- DDR2 is also not the best choice for our days. Today you will hardly find such a type of memory slots. The
- DDR3 is a more modern type, but it also loses its relevance.
- DDR4 is the leader of our time. Has the best performance and wins in all respects. It is an evolutionary development of previous models and perfectly feels on the market since 2014.
- DDR5 is just around the corner. Leading engineers promise that this product will manifest itself closer to 2019.
All the examples that you see below will be provided for the latest generation of devices.
Volume
If you ever thought how to choose a memory module for a computer, then you should already be aware of this parameter. About the amount of memory heard by any user who "communicates" with the computer on an amateur level.
Important: Memory RAM is the amount of information that RAM can hold at a time. The more this characteristic, the better for the device.
The volume should be chosen based on individual preferences and the purpose of the purchase:
- For the office, 4-8 gigabytes will suffice.
- But in order to play modern games and use a professional highly specialized software, you will have to purchase 16-32 GB slats.
Important! The growth of memory in the market is accompanied by a price increase, remember this when you make a choice.
Clock frequency
The speed of data exchange with the "brain" of the computer depends on the values of this parameter. The higher the frequency, the higher the speed.
Important! The clock speed should in no case exceed the frequency of the motherboard, otherwise - you may encounter system failures.
Delays
Timings inversely affect the performance and the price category of devices. Time delays are indicated in the form of a numerical sequence of three elements, each of which is responsible for its parameter:
- CAS Latency - Cycle time.
- RAS to CAS Delay - Full access time.
- RAS Precharge Time - Precharge time.
Voltage
This parameter directly affects heat generation and energy consumption. Modern models have long come to power, which is slightly more than one volt. By this criterion of choice, you will not swing wildly, as any manufacturer closely follows the strain of the work of his product.
Important! Do not attempt to change the voltage supply through the BIOS.Such manipulations can lead to the breakdown of your device or more dangerous consequences.
Manufacturers of
The global market has been captured by giant manufacturers, which always try to please users, making the characteristics of the strips better and better. Such gestures can not but rejoice users, but it is worthwhile to understand that good quality is worth good money. We recommend to rely on the advice of experienced users in these matters, since something definite about each manufacturer can not be said.
to the contents ↑tips Now that you know how to pick up the RAM on your computer, it only remains to give a couple of tips for the future:
- If possible, use several slats instead of one larger.
Important! Use the memory of the same manufacturer with the same characteristics and responses.
- Did the choice fall on the components for the laptop? This article is also great for these devices. All the difference between these devices is only in size and form factor.
- There are two favorites, but one of them has such a cost, which can not be afforded? Find the bar with the same parameters, but with large timings.
These instructions and tips will protect you from choosing a bad RAM.Spend your money wisely and remember the compatibility of components, many novice users literally "burn out" at this stage. Good luck!
