How to choose a laptop memory

Before choosing a memory, it’s worth considering that there are two of them in a laptop – prompt and constant.

How to choose a memory for a laptop: operational and permanent

When choosing a memory for a laptop, you need to pay attention to the following parameters:

  1. For RAM – standard and volume;

  2. For read-only memory, type and size.

  3. RAM and read-only memory are so different components that are not interchangeable.

RAM Standard

Standard RAM

RAM slots for laptop are made in slightly different form factor and size than desktop a computer. They have physically smaller dimensions. This size called SO-DIMM.

But, like RAM for a desktop computer, they exist in several generations (standards), which, in addition to among other things, they differ in compatibility with the motherboard. Today The following are presented on the market:

  1. DDR2;

  2. DDR3;

  3. DDR3L;

  4. DDR4.

It is necessary to choose the exact standard of RAM that Designed for installation on a motherboard. Bar Type DDR3 it’s not possible to plug into the slot for DDR2, and vice versa. Find out which RAM is used in the laptop, you can computer specifications by looking at the markings on motherboard or already installed trims, as well as with using diagnostic programs such as AIDA64.

For maximum performance, it is also desirable that the frequency of all the bars was the same and coincided with the bus frequency RAM on the motherboard. You can find out this parameter. from the technical characteristics of the computer or through the same AIDA64. But if the frequency does not coincide – that’s okay. Just performance will drop to item performance with minimum frequency.

RAM size

When calculating the required amount of RAM for a laptop it is necessary to take into account the capacity of the entire kit, and not one die. The optimal value of this parameter depending on The intended uses are as follows:

  1. 1 GB – for very weak laptops with the appropriate OS;

  2. 2 GB – for “typewriters” (laptops for home and office);

  3. 4 GB – the most recommended minimum size in 2017;

  4. 8 GB – for productive laptops;

  5. 16 GB or more – for gaming laptops and mobile workers stations.

It should be noted that RAM does not determine computer specifications, complements them. So if in a laptop set the bar to 32 GB – it will not become a game.

Type of read-only memory

SSD vs HDD

In most cases, laptops use hard drives 2.5 inches in size. Only in a few modern models mobile computers use special drives that are connected according to the M.2 standard and therefore have different dimensions.

Hard drives (2.5-inch) for laptops come in two types – HDD and SSD. The first type of drives are used most widely – their can be found in almost all modern laptops. They differ low price for GB of memory and optimal speed.

However, SSDs work many times faster, do not need defragment and tolerate shaking caused by laptop transportation. However, they cost enough expensive, and also have a limited operational period, caused by the limit on the number of rewriting cycles.

SSD and HDD are interchangeable (unless, of course, they are connected via SATA standard), so you can use any drive type.

Some models of modern laptops use SSD M.2 drives – they can only be replaced with similar ones – and flash drives that change exclusively in service centers.

When choosing a 2.5-inch hard drive for maximum performance is also worth considering the generation of the SATA standard. To get the maximum data exchange rate, it is necessary that generation of hard drive and bus match. Those. install on SATA 3 bus SATA 3 drive.

But this is optional. If generations do not match, hard drive will work anyway – but at a speed that provides smaller generation in a bunch.

The amount of permanent memory

The read-only memory of the laptop is the place where the computer stores operating system and user files. Therefore minimal hard disk capacity should be calculated based on its needs. Most popular drive capacities the following:

  1. 200 GB Enough for undemanding users who Store a small number of files on hard drives

  2. 320 GB Optimal volume. Enough to create a music library;

  3. 500 GB Enough to create a movie library with high quality;

  4. 1 TB or more. For gaming laptops. Enough to post on hard drive several modern games.

If there is not enough space, you can transfer user files to external hard drive.

Manufacturers

For both RAM and read-only memory, you can identify several manufacturers whose products deserve trust.

RAM:

  1. Corsair, AMD Radeon, Patriot – relatively expensive solutions, but very technological and with a good retraction system heat;

  2. Transcend is an inexpensive RAM that, however, perfectly fulfills its functions.

Read only memory:

  1. Western Digital, Seagate – release relatively expensive, but reliable HDD

  2. Toshiba, Hitachi – produce both successful and unsuccessful models HDD;

  3. Samsung, Western Digital, Seagate – release reliable SSDs, both SATA and M.2
