Random access memory (RAM) is an integral part of any computer. It serves to store user data. And only the information with which work is in progress at the moment. It is necessary to restart the computer, and the "RAM" will be cleared. Below we will analyze the difference between RAM for a laptop and a PC.
Main types
RAM (RAM) is divided into several types: DDR, DDR II and DDR III. There are also very ancient ones: ROM, SRAM, SDRAM and DRAM. But in this context, they do not interest us, since this is already the last century. These types of “RAM” can now be found in few places. Of these, only SRAM is used. Since this type of OP has a high speed, it is usually used for the processor cache. The manufacture of such a "RAM" is expensive and costly. Therefore, the processors with the largest cache size of the third level and cost a lot of money.
DDR and DDR II are also slowly becoming a thing of the past. Their speed and memory capacity cannot be compared to DDR III. Nowadays, it is DDR III - the optimal RAM for laptop and PC.
What is a DDR?
Double Data Rate is an “advanced” version of SDRAM. DDR translates from English as "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 the two is memory performance.
For example, the first generation DDR RAM can work on a bus with a frequency of 100-400 MHz. And DDR III freely "flies" on buses with a frequency of 800-1600 MHz. Accordingly, DDR III is able to perform the most operations per second, consuming the least amount of electricity. This parameter is relevant in some cases. For example, RAM for a laptop should use a small amount of electricity to increase battery life. For a PC, this option is not particularly important. If only in terms of energy savings in general.
HDD
In addition to operational, sometimes the phrase "laptop memory" means an internal storage device. This is the so-called hard drive. The principle of its operation is no different from the component that is present on desktop computers. Only the size is different. And contrary to almost all other components of the laptop, the replacement of the hard drive 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 fine with different laptops.
Choosing the best RAM for your PC
In order to choose the optimal “RAM” for a computer or laptop, you need to know some nuances. And in the case of the desktop computer, everything is much simpler. In order to add memory to a laptop, you need to keep in mind several important points, but about them a little later.
So, to select the OP for the PC, you need to find out the maximum bus frequency supported by your motherboard. It makes no sense to buy a "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 to solve any "super tasks", then the "bar" of 16 GB is enough.
In addition to all this, you need to monitor the amount of electricity consumed. If you come across a "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, laptop RAM is usually limited to about the same power consumption. And this is very beneficial for the owner.
The choice of "RAM" for a 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 low-power RAM. To choose the "right" RAM for an ASUS laptop, for example, you have to look for exactly DDRL. This company often installs just such devices in their laptops. If you insert two different microcircuits into the laptop, then there will be a conflict of components and the computer simply will not work. To determine the type of installed "RAM" is recommended to use the program AIDA 64. She will explain everything thoroughly.
In order to select RAM for a laptop, you should also know the frequency of its bus. This is not a PC, and here it will no longer be possible to put an OP frequency. If your “RAM” should work at a frequency of 1066 MHz, then you need to buy one.
RAM increase
Some laptops have a slot for additional OP. This, of course, does not mean at all that you can add it ad infinitum. Usually, the manufacturer strictly limits the possible amount of memory. Often this information is indicated in the technical specifications of the device.
How to increase memory on a laptop? The easiest option is to buy a “bar” identical to the one already installed. This will help to understand the volume and frequency of the tire. In addition, there will be no equipment conflict. The "slats" of RAM from different manufacturers do not really want to "be friends" with each other.
If you want to replace all the RAM at once, then first you will have to study some characteristics of your OP. For example, bus frequency, maximum volume, as well as the amount of electricity consumed. Nevertheless, it is recommended to buy two “bars” of the same manufacturer. Less likely to conflict. Choosing RAM for a laptop, it 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 is capable of. The right choice in this case will increase productivity several times. Naturally, if you make a mistake, you can "hang" the whole system. But with the help of this article and some programs, you can choose the "right" RAM for a laptop and PC.
