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).

LED lighting

The presence of its own LED backlight on the motherboard. This feature does not affect the functionality of the "motherboard", but gives it an unusual appearance. Therefore, it hardly makes sense for an ordinary user to specifically look for such a model (a motherboard without backlighting is enough for him), but for modding lovers, backlighting can be very useful.

LED backlighting can take the form of individual lights or LED strips, come in different colours (sometimes with a choice of colours) and support additional effects — flashing, flickering, synchronization with other components (see "Lightning synchronization"), etc. Specific features depend on the motherboard model.

Size (HxW)

Motherboard dimensions in height and width. It is assumed that the traditional placement of motherboards is vertical, so in this case one of the dimensions is called not the length, but the height.

Motherboard sizes are largely determined by their form factors (see above), however, the size of a particular motherboard may differ slightly from the standard adopted for this form factor. In addition, it is usually easier to clarify the dimensions according to the characteristics of a particular motherboard than to look for or remember general information on the form factor. Therefore, size data can be given even for models that fully comply with the standard.

The third dimension — thickness — is considered less important for a number of reasons, so it is often omitted.

Chipset

The chipset model installed in the motherboard. AMD's current chipset models are B450, A520, B550, X570, A620, B650, B650E, X670, X670E, X870, X870E.. For Intel, in turn, the list of chipsets looks like this: X299, H410, B460, H470, Z490, H510, B560, H570, Z590, H610, B660, H670, Z690, B760, Z790, Z890.

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.

DDR4

The number of slots for DDR4 memory sticks provided in the motherboard.

DDR4 is a further (after the third version) development of the DDR standard, released in 2014. Improvements compared to DDR3 are traditional — an increase in operating speed and a decrease in power consumption; The volume of one module can be from 2 to 128 GB. It is this RAM standard that most modern motherboards are designed for; the number of slots for DDR4 is usually 2 or 4, less often — 6 or more.

Max. memory

The maximum amount of RAM that can be installed on the motherboard.

When choosing according to this parameter, it is important to take into account the planned use of the PC and the real needs of the user. So, volumes up to 32 GB inclusive are quite enough to solve any basic problems and run games comfortably, but without a significant reserve for an upgrade. 64 GB is the optimal option for many professional use cases, and for the most resource-intensive tasks like 3D rendering, 96 GB or even 128 GB of memory will not be a limit. The most “capacious” motherboards are compatible with volumes of 192 GB or more - they are mainly top-end solutions for servers and HEDT (see “In the direction”).

You can choose this parameter with a reserve – taking into account a potential RAM upgrade, because installing additional RAM sticks is the simplest way to increase system performance. Taking this factor into account, many relatively simple motherboards support very significant amounts of RAM.

XMP

The ability of the motherboard to work with RAM modules that support XMP (Extreme Memory Profiles) technology. This technology was developed by Intel; it is used in motherboards and RAM blocks and only works if both of these system components are XMP compliant. A similar technology from AMD is called AMP.

The main function of XMP is to facilitate system overclocking (“overclocking”): special overclocking profiles are “sewn” into the memory with this technology, and if desired, the user can only select one of these profiles without resorting to complex configuration procedures. This is not only easier, but also safer: every profile added to the bar is tested for stability.

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.
