Features
The general specialization of the motherboard is the type of tasks for which it is optimized. It should be noted that the division according to this indicator is often rather conditional, models similar in characteristics may belong to different categories. However, the data on specialization greatly simplifies the choice.
In addition to the traditional "motherboards"
for home and office, nowadays you can find solutions
for high-end PCs (High-End Desktop) and
for servers, as well as
gaming boards and models
for overclocking(the last two options are sometimes combined into one category , however, these are still different types of motherboards). There are also specialized models
for cryptocurrency mining, but very few of them are produced — especially since many boards that originally had a different purpose are suitable for mining (see "Suitable for mining").
Here is a more detailed description of each variety:
— For home and office. Motherboards that do not belong to any of the more specific types. In general, this kind of "motherboards" is very diverse, it includes options from low-cost motherboards for modest office PCs to advanced models that come close to gaming and HEDT solutions. However, for the most part, solutions from this category
...are designed for simple everyday tasks: working with documents, web surfing, 2D design and layout, games in low and medium quality, etc.
— Gamer's. Boards originally designed for use in advanced gaming PCs. In addition to high performance and compatibility with powerful components, primarily video cards (often several at once, in SLI and/or Crossfire format — see below), such models usually also have specific features of a gaming nature. The most noticeable of these features is the characteristic design, sometimes with backlighting and even backlight synchronization (see below), which allows you to organically fit the board into the original design of the gaming station. The functionality of gaming boards may include an advanced audio chip, a high-end network controller to reduce lags in online games, built-in software tools for tuning and optimizing performance, etc. Also, such models may provide advanced overclocking capabilities, sometimes not inferior to the capabilities of specialized boards for overclocking (see below). And sometimes the border between gaming and overclocking solutions is generally erased: for example, individual boards positioned by the manufacturer as gaming ones, in terms of functionality, can more likely be related to overclocking models.
— For overclocking. High-performance boards with an extended set of overclocking tools — improving system performance by fine-tuning individual components (mainly by increasing the clock frequencies used by these components). On most conventional motherboards, this setup involves considerable complexity and risk, it is usually an undocumented feature and is not covered by the warranty. However, in this case, the situation is the opposite: boards "for overclocking" are called so because the possibility of overclocking was originally incorporated in them by the manufacturer. One of the most noticeable features of such models is the presence in the firmware (BIOS) of special software tools for overclocking management, which makes overclocking as safe as possible and affordable even for inexperienced users. Another feature is improved compatibility with built-in overclocking tools provided in advanced processors, RAM modules, etc. Anyway, this particular type of board will be the best choice for those who want to build a fairly powerful PC with the ability to experiment in terms of performance.
— HEDT (High End Desktop). Motherboards designed for high-performance workstations and other PCs of a similar level. In many ways, they are similar to gaming ones and are sometimes even positioned as gaming ones, but they are designed more for general performance (including in professional tasks) than for confident work with games. One of the key features of such "motherboards" is the extensive functionality for working with RAM: they provide at least 4 slots for "RAM", and more often 6 or more, the maximum RAM frequency is at least 2500 MHz (and more often 4000 MHz and higher ), and the maximum volume is at least 128 GB. The rest of the characteristics are usually at a similar level. Also, the firmware may provide tools for overclocking, although in terms of this functionality, such boards are most often still inferior to overclockers. Note that such solutions can initially be positioned as gaming; the basis for categorization in the HEDT category in such cases is the fulfillment of the above criteria.
— For the server. Motherboards specially designed for servers. Such systems are noticeably different from conventional desktop PCs — in particular, they work with large volumes of drives and have increased requirements for the speed and reliability of data transfer; accordingly, to build servers, it is best to use specialized components, including motherboards. Among the main features of such motherboards are an abundance of slots for RAM (often more than 4), the ability to connect numerous drives (necessarily more than 4 SATA 3 slots, often 8 or more), as well as support for special technologies (like ECC — see below) . In addition, such boards can be made in specific form factors such as EEB or CEB (see "Form Factor"), although more traditional options are also found.
— Designed for mining. Motherboards specially designed for cryptocurrency mining (BitCoin, Ethereum, etc.). We emphasize that we are not just talking about the possibility of such an application (see “Suitable for mining”), but that the motherboard is initially positioned as a solution for creating a cryptocurrency “farm”. Recall that mining is the extraction of cryptocurrency by performing special calculations; such calculations are most conveniently carried out using several high-performance video cards at once. Accordingly, one of the distinguishing features of mining boards is the presence of several (usually at least 4) PCI-E 16x slots for connecting such video cards. However, this category of “motherboards” has not received much distribution: similar characteristics are also found among more general-purpose boards, it is quite possible to achieve performance sufficient for efficient mining on them.Chipset

A chipset is a set of chips on the motherboard through which the individual components of the system interact directly: the processor, RAM, drives, audio and video adapters, network controllers, etc. Technically, such a set consists of two parts — the north and sou
...th bridges. The key element is the northbridge, it connects the processor, memory, graphics card and the southbridge (together with the devices it controls). Therefore, it is often the name of the north bridge that is indicated as the chipset model, and the south bridge model is specified separately (see below); it is this scheme that is used in traditional layout motherboards, where bridges are made in the form of separate microcircuits. There are also solutions where both bridges are combined in one chip; for them, the name of the entire chipset can be indicated.
Anyway, knowing the chipset model, you can find various additional data on it — from general reviews to special instructions. An ordinary user, usually, does not need such information, but it can be useful for various professional tasks.M.2
Electrical (logical) interfaces implemented through physical M.2 connectors on the motherboard.
See above for more details on such connectors. Here we note that they can work with two types of interfaces:
- SATA is a standard originally created for hard drives. M.2 usually supports the newest version, SATA 3; however, even it is noticeably inferior to PCI-E in terms of speed (600 MB / s) and functionality (only drives);
- PCI-E is the most common modern interface for connecting internal peripherals (otherwise NVMe). Suitable for both expansion cards (such as wireless adapters) and drives, while PCI-E speeds allow you to fully realize the potential of modern SSDs. The maximum communication speed depends on the version of this interface and on the number of lines. In modern M.2 connectors, you can find PCI-E versions 3.0 and 4.0, with speeds of about 1 GB / s and 2 GB / s per lane, respectively; and the number of lanes can be 1, 2 or 4 (PCI-E 1x, 2x and 4x respectively)
Specifically, the M.2 interface in the characteristics of motherboards is indicated by the number of connectors themselves and by the type of interfaces provided for in each of them. For example, the entry "3xSATA / PCI-E 4x" means three connectors that can work both in SATA format and in PCI-E 4x format; and the designation "1xSATA / PCI-E 4x, 1xPCI-E 2x" means two connectors, one of which works as SATA or PCI-E 4x, and the second — only as PCI-E 2x.
CrossFire (AMD)
Motherboard support for
AMD's Crossfire technology.
This technology allows you to connect several separate AMD graphics cards to a PC at once and combine their computing power, respectively increasing the system's graphics performance in specific tasks. Accordingly, this feature means that the "motherboard" is equipped with at least two slots for video cards — PCI-E 16x; in general, Crossfire allows up to 4 separate adapters to be connected.
Such functionality is especially important for demanding games and "heavy" tasks like 3D rendering. However, note that in order to use several video cards, this possibility must also be provided in the application running on the computer. So in some cases, one powerful video adapter is more preferable than several relatively simple ones with the same total amount of VRAM.
A similar technology from NVIDIA is called SLI (see below). Crossfire differs from it mainly in three points: the ability to combine video adapters with different models of graphics processors (the main thing is that they are built on the same architecture), no need for additional cables or bridges (video cards interact directly via the PCI-E bus) and somewhat lower cost (allowing the use of this technology even in low-cost "motherboards"). Thanks to the latter, almost all motherboards with SLI also support Crossfire, but not vice versa.
TPM connector
Specialized
TPM connector for connecting the encryption module.
TPM (Trusted Platform Module) allows you to encrypt the data stored on your computer using a unique key that is practically unbreakable (it is extremely difficult to do this). The keys are stored in the module itself and are not accessible from the outside, and data can be protected in such a way that their normal decryption is possible only on the same computer where they were encrypted (and with the same software). Thus, if information is illegally copied, an attacker will not be able to access it, even if the original TPM module with encryption keys is stolen: TPM will recognize the system change and will not allow decryption.
Technically, encryption modules can be built directly into motherboards, but it is still more justified to make them separate devices: it is more convenient for the user to purchase a TPM if necessary, and not overpay for an initially built-in function that may not be needed. Because of this, there are motherboards
without a TPM connector at all.
ARGB LED strip
Connector for connecting an addressable LED strip as a decorative lighting for a computer case. This type of "smart" tape is based on special LEDs, each of which consists of an LED light and a built-in controller, which allows you to flexibly control the luminosity using a special digital protocol and create amazing effects.
RGB LED strip
Connector for connecting a decorative LED strip and other devices with LED indication. Allows you to control the backlight of the case through the motherboard and customize the glow for your tasks, including synchronize it with other components.
DVI output
The motherboard has its own
DVI output; this clause also specifies the specific form of this interface.
Such an output is intended for transmitting video from an integrated graphics card (see above) or a processor with integrated graphics (we emphasize that it is impossible to output a signal from a discrete graphics card through the motherboard chipset). As for DVI specifically, this is a standard originally created for digital video devices, however, it also allows an analogue signal format, depending on the type. In modern computer technology, including motherboards, you can find two types of DVI:
— DVI-D. A standard that provides for the transmission of a signal only in digital form. Depending on the supported mode, the maximum resolution of such video can be 1920x1200 (single-link Single Link) or 2560x1600 (two-channel Dual Link); however, Single Link plugs can be connected to Dual Link ports, but not vice versa. Also note that such connectors are compatible with HDMI via adapters, while in some cases even sound transmission may be provided (although this function is not initially supported in DVI-D, and its availability should be specified separately).
— DVI-I. A standard that combines the DVI-D described above with analogue DVI-A and allows the signal to be output in both digital and analogue formats. DVI-A in its characteristics corresponds to VGA (see above): it supports resolutions up to 1280x1024
...inclusive and allows you to connect VGA screens through a simple adapter.DisplayPort
Availability of
DisplayPort output on the motherboard.
Primarily, this digital connector is used to transmit video from the built-in video card or processor with integrated graphics to external screens. Moreover, through one DisplayPort interface it is possible to connect several displays in series in a “chain” (“daisy chain” format). Specific output capabilities vary by version (see below), but even the most modest DisplayPort specification (among modern options) allows 4K at 60 fps, 5K at 30 fps, and 8K with some limitations.
The DisplayPort interface is a standard for Apple monitors and is found in screens from other manufacturers.
