When the operating system is started it "loads" from the HDD to the RAM. The same process happens with all the applications and files opened with them. Therefore it is very important to have enough space in the RAM for all the above data for enabling the CPU to handle this information at a high speed.

If insufficient capacity RAM has been selected the CPU starts to use the HDD for its short-term operations and the computer becomes extremely slow at this moment. Therefore it is important to buy the memory volume required for handling the relevant tasks.

For average use, like the Internet browsing, working with documents and enjoying multimedia possibilities, 4GB RAM is fully sufficient.

For demanding 3D computer games, video/audio editing applications and any professional software at least 8GB RAM is required.

You should remember that there is never too much RAM. Therefore, if you can afford it you should buy more. Still you should take into account that the RAM is a parameter which can be upgraded by buying additional volume later if there are enough free memory connection slots in the motherboard.

The most important difference between video cards is in their GPU or the central graphics core. This parameter determines the graphic performance and can be improved only if the whole card is replaced with another one.

Also video cards with equal GPU and model may differ by the volume of the graphic memory, the memory type, the cooling type and clock frequencies.

The graphic memory volume provides a possibility to play 3D games at a higher resolution, therefore, if you like games and plan to buy a big monitor or several monitors you should select a video card with the memory capacity of at least 1GB. If a video card is short of graphic memory it may "borrow" the necessary volume from the computer RAM. Still the difference in speed is considerable and in favour of the graphic memory.

You should pay attention to the memory type and frequency. DDR3 memory is better than DDR2 and slower than DDR5. And also DDR3 1800MHz memory will be faster than 1600MHz memory of the same type. Also the memory bandwidth is important within one memory type. Thus, DDR3 256bit memory will be faster than DDR3 128bit memory.

The type and quality of cooling is among the most important selection criteria of a video card. A good cooler contains one big or several small cooler and a bigger radiator than the standard cooling equipment of the relevant video card. You should ask our managers and they will help to select the best offer.

It is possible to buy a good cooler as a separate device, however, it is quite expensive ~25 LVL, therefore it is better to buy a card with sufficiently good cooling included.

When cards with identical GPU are selected you should pay attention to the availability of OC (OverClock) or industrially overclocked versions of the card. This type of the card secures higher graphic performance, still it has to be taken into account that it is usually achieved on the account of more intense (louder) cooling and operational stability.

The first M.2 SSDs appeared on the market shortly after the debut of Intel's Haswell architecture at the end of 2013. However, they didn't gain popularity until late 2015, when Intel's Skylake architecture and 100-series motherboards became more and more common to find M.2 sockets on. By early 2017, with the launch of Intel's 7th generation Kaby Lake and AMD Ryzen processors, almost all Z270 and X370 motherboards are equipped with one or even more M.2 sockets.

M.2 drives are basically available in 3 standards, which basically denote their physical characteristics - M.2 2280 (card size 22x80mm), M.2 2260 (22x60mm), M.2 2242 (22x42mm), but the M.2 technical specification also allows other sizes.

Unfortunately, physical dimensions are not the only differences that can be found in M.2 SSDs. The interface that these cards use to connect to the CPU is also different. Currently, two types of M.2 SSD are most widely used - SATA and PCI-Express. M.2 SSDs are capable of speeds up to 600 MB/s via the SATA interface, which is limited by the current SATA 3 protocol. It is because of this limitation that M.2 was adapted to be compatible with the PCI-Express bus to provide higher data transfer rates, which can reach up to 4 GB/s via the PCI-E interface! Several drives are already capable of read speeds of 2500 MB/s and more.

The main thing to remember is that despite the similarity of the ports, these drives are not compatible with each other! On a board with an M.2 socket connected only to the SATA interface, it will not be possible to use a PCI-E interface M.2 SSD and vice versa. However, from 2017 onwards, with the Intel B250, H270 and Z270 motherboards as well as the AMD X370 motherboards, almost all M.2 sockets are universal and support both SATA and PCI-Express interface M.2 SSDs. We always recommend checking the board manufacturer's website for this though.

An SSD disc consists of microchips, thus there are no moving parts in it and it is completely silent (0 dB). Due to this fact an SSD disc is more resistant to vibration and other mechanical impact than an HDD.

Due to the construction specifics higher volume SSD discs usually are higher-speed and the different in the speed can be even multifold. Therefore prior to buying it you should study carefully the indices of the operation speed of the SSD disc - reading and writing speed in Megabytes per second (MB/s). The operation speed of an average SSD disc has to be ~250 MB/s. Read un ~200 MB/s. Write. For high performance discs these indices will be ~350 MB/s Read un ~450MB/s Write accordingly. 

The operation speed and volume of SSD discs is improving rapidly and the prices are falling. Therefore you should buy this type of disc only when the high-speed operation and silence are more important than the relevant investment.

Only the users who like to save everything or whose work specifics include a high volume of data, like, professional editing of photos and videos, large scale database systems, etc., should buy a disc above 1TB. For an average user a 1TB disc is "more than enough"

Besides the volume it is also necessary to select the speed of the disc. It is determined by the index of rotations per minute (rpm) and the cache memory. A 1000rpm disc will be faster than 7200rpm (and also more noisy in operation). At the same rotation index a disc with 64MB cache memory will be faster than a disc with 32MB cache memory, etc.

The disc parameters can be improved by purchasing additional disc and the number depends on the 3.5" HDD niches of the housing and the capacity of the power supply unit (an average HDD consumes approximately 25W power supply.)

The type of the connection slot SATAII and SATAIII are not very important as these are mutually compatible standards and (in case of HDDs) are not very important for the high-speed of data transmission.

When the operating system is divided from the data the OS and the software usually is places on a smaller size and higher speed disc. A high volume disc with a lower rpm index is devoted for the data as this solution ensures a higher safety of the data thanks to lower rotation speed and operating temperature. However, the discs should be located at a sufficient distance from each other, because in the contrary case they should be cooled with a ventilator.

If the selected motherboard does not provide the RAID data array it is worth considering the purchase of another disc due to two possible types of application:

RAID 0, or STRIPE is a data array capable of increasing the data reading/ writing speed considerably on the account of serial using of both discs (and data stability). If this connection is used a double risk has to be assumed - if one disc fails the total data array no longer operates and the data are lost. The discs of an identical model and manufacturer are used for this type of data array.

RAID 1, or MIRROR data array consists of two similar discs to which all the data are copied simultaneously and identically, thus ensuring the safety of the data against the damage of one disc. For this type of data array it is desirable to choose each disc of a different manufacturer or closely similar model due to the fact that in case of a manufacturing defect the discs of the same type can have the same defect increasing the risk of losing the data.

Besides the above referred RAID types there are also combined RAID 5 and RAID 6 which ensure the data safety and the increase of the operation speed at the same time, however, these data arrays require 3 and more discs accordingly as well as a specialized controller. You should inquire about the possibilities of setting up a computer with RAID 5, 6 data arrays by contacting our managers at

For an average home or small office user without any specific requirements we recommend to buy the Windows 7 English 64bit version.

You should choose the 32bit software only in the case when you plan to use the software that has known compatibility problems with the 64bit operating system or devices that do not have 64bit drivers. However, most of the 32bit software can operate within the 64bit operating system.

All the computers and components offered by Dateks provide full support of the 64bit operating system, therefore we recommend this choice because of the fact that the support of the RAM above 3 GB is possible only in 64bit mode and this type of operating systems is gradually becoming the leading standard and it is inevitable that it will fully replace the 32bit systems in future.

When you buy an operating system you should choose carefully the language of the user interface as it will not be possible to change this language later (except the Ultimate version which is multilingual). We offer English, Latvian and Russian interface languages of the operating system.

Entrepreneurs are entitled to use all the operating systems offered by legally, including Windows Home Premium. It has to be taken into account that the connection to Microsoft domain servers is possible only with Windows Pro and Ultimate versions.

Windows Ultimate offers additional BitLocker data encoding application and a possibilities to switch over between the user's interface languages without changing the license.

For those preferring 3D games we recommend to pay attention to the panel response time. The lower this index the better. 2ms is considered the best index.

Those working with photo and graphics tasks as amateurs or professionals should pay attention to the matrix type. We recommend VA and IPS type matrix due to higher colour compliance indices.

We recommend to select a monitor with DVI or HDMI connection ports that use the digital transmission principle ensuring stable image quality.

When you buy a wireless keyboard you have to accept quite regular replacement of batteries. New batteries are included with all the wireless keyboards sold by .

We offer also sets - a keyboard with a mouse. In most cases such a set is cheaper than a keyboard and a mouse bought separately, they are also compatible based upon esthetic and functional principles.

More expensive keyboards can offer also additional functions of which we think that the lighting of keys to make the work with a computer easier in dark is most useful.

Besides the keyboards of standard size and form also the keyboards of portable computer type are available - they have lower set keys and sometimes do not have the separate number pad. This type of keyboards are more esthetic and require less space, however, for some users they can make typing more difficult.

For users who have to type a lot we offer to buy a keyboard of a curved form that will feel better for palms ensuring the correct position of the palm. Also keyboards with mechanical keys are available and these provide a higher accuracy for fast typing users, however, this keyboard is much more expensive than standard models and it is also more noisy in operation. 

Gaming mice have been constructed for enjoying games and ensure the optimum combination of the accuracy and convenience for long-term operation of the computer.

When you buy a wireless keyboard you have to accept quite regular replacement of batteries. New batteries are included with all the wireless keyboards sold by . More expensive models have a battery pack and a charger.

The purchased license is in the PKC (product key card) form which is a simple serial number. It is possible to download the software installation package from the Microsoft website and activated by using this number after the installation.

We would like to remind you that if you buy the license from us together with a new computer we will perform the required installation work for you free of charge, thus you will receive the computer ready for work with all the purchased software.

The license of antivirus software are terminated for a certain time period which is usually 1 year. After the expire of this term the antivirus software will continue running, however, the access to updates is no longer available. The software will notify on the approach of the license term in due time and will offer to buy updates.

Besides the antivirus software also the Internet Security software sets are available and they include additional protection functions, for example, the firewall, malware protection and browser protection). You should look for these sets under the section "akternatives" under the preferred antivirus software developer.

recommends Kaspersky Lab software.

For ensuring the power supply of an average computer for 5 minutes after a power cut it is sufficient to have ~600VA UPS.
