Memory for a laptop: types of memory and ways to increase

RAM (RAM) is an integral part of any computer. It serves to store user data. And only the information with which the work is currently in progress. It's worth rebooting the computer, and the "RAM" will be cleared. A little lower, we'll figure out what the difference in RAM for a laptop and for a PC.

Basic views

RAM (RAM) is divided into several types: DDR, DDR II and DDR III. There are also very ancient: ROM, SRAM, SDRAM and DRAM. But in this context they do not interest us, since this is the last century. These types of "operatives" are few where you can now meet. Of these, only SRAM is used. Because this type of OD has an increased speed, it is usually used for the processor's cache. Making such an "operative" is expensive and expensive. Therefore, processors with the largest cache size of the third level and are worthless money.

DDR and DDR II are also slowly disappearing into the past. Their speed and memory size do not go to any comparison with DDR III. Nowadays, it is DDR III - optimal RAM for laptop and PC.

What is DDR?

Double Data Rate is an "advanced" version of SDRAM. DDR is translated from English as a "double data rate." This means that the speed of information exchange "RAM" with the processor is several times higher than that of SDRAM. The serial number, following the abbreviation, denotes the generation of OP. The difference between them is the speed of memory.

For example, first-generation DDR memory can run on a 100-400 MHz bus. And DDR III freely "flies" on tires with a frequency of 800-1600 MHz. Accordingly, DDR III is able to perform the greatest number of operations per second, spending the least amount of electricity. This parameter is actual in some cases. For example, RAM for a laptop should use a small amount of electricity to increase battery life. For PC this parameter is not particularly important. If only in terms of saving energy in general.

HDD

In addition to the operational, sometimes under the phrase "memory for a laptop" is meant an internal storage of information. This is the so-called hard disk. The principle of its operation does not differ from the component that is present in desktop computers. The only difference is the size. And in spite of almost all other components of the laptop, hard drive replacement is provided on all more or less modern devices. The process does not require much effort. It is not necessary to comply with the previous manufacturer, all hard drives work perfectly with different laptops.

Choosing the best RAM for your PC

To properly choose the optimal "RAM" for a computer or laptop, you need to know some nuances. And in the case of a desktop computer, everything is much easier. In order to add memory to the laptop, you need to keep in mind a few important points, but about them a little later.

So, to select the OP for the PC you need to know the maximum bus frequency supported by your motherboard. It makes no sense to purchase "RAM" with a frequency of 1300 MHz, if your motherboard supports 1600 MHz. Then you need to determine the amount of "RAM". If the computer does not plan any "super-task" solution, then the 16-GB "slats" will suffice.

In addition to all this, you need to monitor and the amount of electricity consumed. If you get "gluttonous" memory, then the power of your power supply may not be enough to provide all the components of the computer. In cases with portable devices everything is much simpler. For example, RAM for a laptop is usually limited to about the same energy consumption. And this is very beneficial for the owner.

Selecting "RAM" for the laptop

Before replacing, you need to find out which "bar" you have installed. The fact is that such a popular DDR has one interesting subspecies - DDRL. This is a RAM with low power consumption. To select the "right" memory for the ASUS laptop, for example, you will have to look for DDRL. This company often installs such devices in their laptops. If you insert two different chips in the laptop, then there will be a conflict of components and the computer simply will not work. To determine the type of installed "RAM" it is recommended to use the program AIDA 64. She will explain everything thoroughly.

In order to select the RAM for the laptop, you should also know the frequency of its bus. It's not a PC, and here it's no longer possible to put the OP back on. If you have "RAM" should work at a frequency of 1066 MHz, then this and you need to buy.

Increase RAM

Some laptops have a slot for an additional OP. This, of course, does not mean that you can add it forever. Usually, the manufacturer tightly limits the possible amount of memory. Often this information is indicated in the technical characteristics of the device.

How to increase memory on a laptop? The simplest option is to buy a "bar" identical to the one already installed. This will help to understand the volume and frequency of the bus. In addition, there will be no conflict of equipment. The "slats" of RAM from different manufacturers do not particularly want to "make friends" with each other.

If you want to replace all RAM at once, then first you will have to learn some characteristics of your OP. For example, the bus frequency, the maximum volume, as well as the amount of electricity consumed. And yet it is recommended to buy two "slats" of the same manufacturer. Less likely to conflict. Choosing the operating memory for a laptop is important to remember about the technical characteristics. Make sure that the bus frequency and voltage match.

Conclusion

RAM allows your computer to demonstrate everything that it can. The right choice in this case will increase the productivity several times. Naturally, if you make a mistake, you can "hang" the entire system. But with the help of this article and some programs, you can choose the "right" RAM for your laptop and PC.
