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.

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 co...ntrollers, etc. Technically, such a set consists of two parts — the north and south 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 SSD cooling

Motherboard-integrated cooling for M.2 SSD drives.

This connector allows you to achieve high speed, however, for the same reason, many M.2 SSDs have high heat dissipation, and additional cooling may be required to avoid overheating. Most often, the simplest radiator in the form of a metal plate is responsible for such cooling — in the case of an SSD, this is quite enough.

Integrated RAID controller

The presence of a built-in RAID controller on the motherboard. This function allows you to create RAID arrays from drives connected to the system using only the tools of the motherboard itself, in other words, through the standard BIOS or UEFI (see above), without using additional hardware or software.

RAID is a set (array) of several interconnected drives, perceived by the system as a whole. Depending on the type of RAID, it can provide an increase in read speed or increased reliability of information storage. Here are some of the more popular types:

— RAID 0 — data is written one by one to each of the connected disks (one file may be written to different disks). Provides performance improvements, but not fault tolerance.

— RAID 1 — information written to one of the disks is "mirrored" on all the others. Provides increased reliability by reducing system effective capacity.

— RAID 5 — information is written one by one, as in RAID 0, however, in addition to the main data, the so-called disks are also written to disks. checksums that allow you to restore information in the event of a complete failure of one of the disks. It has good fault tolerance and does not reduce the useful volume of disks as much as RAID 1, however, it is relatively slow and requires a minimum of 3 disks (two are enough for the previous types).

There are other varieties, they are used less often. Different moth...erboards may support different types of RAID, so before buying a model with this feature, it's ok to check the details separately.

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-E 16x slots

Number of PCI-E (PCI-Express) 16x slots installed on the motherboard.

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. 16 lanes is the largest number found in modern PCI Express slots and cards (more is technically possible, but the connectors would be too bulky). Accordingly, these slots are the fastest: they have a data transfer rate of 16 GB / s for PCI-E 3.0 and 32 GB / s for version 4.0 (for more information about the versions, see "PCI Express Support").

Separately, we note that it is PCI-E 16x that is considered the optimal connector for connecting video cards. However, when choosing a motherboard with several such slots, it is worth considering the PCI-E modes supported by it (see below). In addition, we recall that the PCI Express interface allows you to connect boards with a smaller number of lines to connectors with numerous lines. Thus, PCI-E 16x will fit any PCI Express card.

It is also worth mentioning that in the design of modern "motherboards" there are slots of increased sizes — in particular, PCI-E 4x, corresponding in size to PCI-E 16x. However, the type of PCI-E slots in our catalog is indicated by the actual throughput; so only connectors that support 16x speed are considered as PCI-E 16x.

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.
