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.

Power phases

The number of processor power phases provided on the motherboard.

Very simplistically, phases can be described as electronic blocks of a special design, through which power is supplied to the processor. The task of such blocks is to optimize this power, in particular, to minimize power surges when the load on the processor changes. In general, the more phases, the lower the load on each of them, the more stable the power supply and the more durable the electronics of the board. And the more powerful the CPU and the more cores it has, the more phases it needs; this number increases even more if the processor is planned to be overclocked. For example, for a conventional quad-core chip, only four phases are often enough, and for an overclocked one, at least eight may be needed. It is because of this that powerful processors can have problems when used on inexpensive low-phase motherboards.

Detailed recommendations on choosing the number of phases for specific CPU series and models can be found in special sources (including the documentation for CPU itself). Here we note that with numerous phases on the motherboard (more than 8), some of them can be virtual. To do this, real electronic blocks are supplemented with doublers or even triplers, which, formally, increases the number of phases: for example, 12 claimed phases can represent 6 physical blocks with doublers. However, virtual phases are much inferior to real ones in terms of capabilities — in fact, t...hey are just additions that slightly improve the characteristics of real phases. So, let's say, in our example, it is more correct to speak not about twelve, but only about six (though improved) phases. These nuances must be specified when choosing a motherboard.

VRM heatsink

The design of the motherboard has a separate heatsink for VRM.

VRM is a voltage regulation module through which power from a computer power supply is supplied to the processor. This module steps down the standard power supply voltage (+5V or +12V) to a lower value required by the processor (usually just over 1V). At high loads, the voltage regulator can get very hot, and without a specialized cooling system, the matter can end with overheating and even burnout of parts. The VRM heatsink reduces the likelihood of such situations; it can be useful for any CPU, and highly desirable if the board is planned to be used with a powerful high-end processor (especially overclocked).

M.2 connector

The number of M.2 connectors provided in the design of the motherboard. There are motherboards for 1 M.2 connector, for 2 connectors, for 3 connectors or more.

The M.2 connector is designed to connect advanced internal devices in a miniature form factor — in particular, high-speed SSD drives, as well as expansion cards like Wi-Fi and Bluetooth modules. However, connectors designed to connect only peripherals (Key E) are not included in this number. Nowadays, this is one of the most modern and advanced ways to connect components. But note that different interfaces can be implemented through this connector — SATA or PCI-E, and not necessarily both at once. See "M.2 interface" for details; here we note that SATA has a low speed and is used mainly for low-cost drives, while PCI-E is used for advanced solid-state modules and is also suitable for other types of internal peripherals.

Accordingly, the number of M.2 is the number of components of this format that can be simultaneously connected to the motherboard. At the same time, many modern boards, especially mid-range and top-end ones, are equipped with two or more M.2 connectors, and moreover, with PCI-E support.

1x PCI-E slots

Number of PCI-E (PCI-Express) 1x slots installed on the motherboard. There are motherboards for 1 PCI-E 1x slot, 2 PCI-E 1x slots, 3 PCI-E 1x ports and even more.

The PCI Express bus is used to connect various expansion cards — network and sound cards, video adapters, TV tuners and even SSD drives. The number in the name indicates the number of PCI-E lines (data transfer channels) supported by this slot; the more lines, the higher the throughput. Accordingly, PCI-E 1x is the basic, slowest version of this interface. The data transfer rate for such slots depends on the PCI-E version (see "PCI Express Support"): in particular, it is slightly less than 1 GB / s for version 3.0 and slightly less than 2 GB / s for 4.0.

Separately, we note that the general rule for PCI-E is as follows: the board must be connected to a slot with the same or more lines. Thus, only single-lane boards will be guaranteed to be compatible with PCI-E 1x.

PCI Modes

Operating modes of PCI-E 16x slots supported by the motherboard.

For more information about this interface, see above, and information about the modes is indicated if there are several PCI-E 16x slots on the board. This data specifies at what speed these slots can operate when expansion cards are connected to them at the same time, how many lines each of them can use. The fact is that the total number of PCI-Express lanes on any motherboard is limited, and they are usually not enough for the simultaneous operation of all 16-channel slots at full capacity. Accordingly, when working simultaneously, the speed inevitably has to be limited: for example, recording 16x / 4x / 4x means that the motherboard has three 16-channel slots, but if three video cards are connected to them at once, then the second and third slots will be able to give speed only to PCI-E 4x level. Accordingly, for a different number of slots and the number of digits will be appropriate. There are also boards with several modes — for example, 16x/0x/4 and 8x/8x/4x (0x means that the slot becomes inoperable altogether).

You have to pay attention to this parameter mainly when installing several video cards at the same time: in some cases (for example, when using SLI technology), for correct operation of video adapters, they must be connected to slots at the same speed.

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.

SLI (NVIDIA)

Motherboard support for NVIDIA SLI technology.

This technology allows you to connect several individual NVIDIA graphics cards to your 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, SLI 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 AMD is called Crossfire (see above). The main difference between these technologies is that SLI is more demanding on compatibility: it only works on video cards with the same GPU models (although other parameters — the manufacturer, the amount and frequency of video memory, etc. — may be different). In addition, video adapters in an SLI bundle must be connected with a cable or a bridge (the only exceptions are some low-cost models); and support for this technology is somewhat more expensive than in the case of Crossfire, so it is less common in motherboards (and mostly together wi...th the solution from AMD).

USB C 3.2 gen1

The number of USB-C 3.2 gen1 connectors provided on the motherboard.

USB-C connectors (all versions) are used to connect to the "motherboard" USB-C ports located on the outside of the case (usually on the front panel, less often on the top or side). With a special cable, such a port is connected to the connector, while one connector, usually, works with only one port. In other words, the number of connectors on the motherboard corresponds to the maximum number of USB-C chassis connectors that can be used with it.

Recall that USB-C is a relatively new type of USB connector, it is distinguished by its small size and double-sided design; such connectors have their own technical features, so separate connectors must be provided for them. Specifically, USB 3.2 gen1 (formerly known as USB 3.1 gen1 and USB 3.0) provides data transfer speeds of up to 4.8 Gbps. In addition, on a USB-C connector, this version of the connection can support USB Power Delivery technology, which allows you to supply power to external devices up to 100 W; however, this function is not mandatory, its presence in the connectors of one or another "motherboard" should be specified separately.
