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).

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.

DualBIOS

Motherboard support for DualBIOS technology.

Crashes and errors in the BIOS (see BIOS) are one of the most serious problems that can occur with a modern PC — they not only make the computer unusable, but also very difficult to fix. DualBIOS technology is designed to make it easier to deal with such problems. Motherboards made using this technology have two chips for writing the BIOS: the first chip contains the main BIOS version, which is used to boot the system in normal mode, the second one contains a backup copy of the BIOS in the original (factory) configuration. The backup chip comes into operation if an error is detected in the main BIOS: if an error is detected in the programme code, it is restored to the original factory version, but if there was a hardware failure, the backup chip takes control of the system, replacing the main one. This allows you to keep your system up and running even in the event of serious BIOS problems without resorting to complex recovery procedures.

Max. clock frequency

The maximum RAM clock speed supported by the motherboard. The actual clock frequency of the installed RAM modules should not exceed this indicator — otherwise, malfunctions are possible, and the capabilities of the “RAM” cannot be used to the fullest.

For modern PCs, a RAM frequency of 1500 – 2000 MHz or less is considered very low, 2000 – 2500 MHz is modest, 2500 – 3000 MHz is average, 3000 – 3500 MHz is above average, and the most advanced boards can support frequencies of 3500 – 4000 MHz and even more than 4000 MHz.

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.

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.

Audiochip

The model of the audio chip (a module for processing and outputting sound) installed on the motherboard. Data on the exact name of the sound chip will be useful when looking for detailed information about it.

Modern "motherboards" can be equipped with fairly advanced audio modules, with high sound quality and extensive features, which makes them suitable even for gaming and multimedia PCs (although professional audio work will still most likely require a separate sound card). Here are the most popular modern audio chips: Realtek ALC887, Realtek ALC892, Realtek ALC1150, Realtek ALC1200, Realtek ALC1220, Realtek ALC4050, Realtek ALC4080, Supreme FX.

LAN controller

Model of the LAN controller installed in the motherboard.

The LAN controller provides data exchange between the card and the network port(s) of the computer. Accordingly, both general characteristics and individual features of the network functionality of the "motherboard" depend on the characteristics of this module: support for special technologies, connection quality in case of unstable communication, etc. Knowing the model of the LAN controller, you can find detailed data on it — including including practical reviews; this information is rarely needed by the average user, but it can be useful for online game enthusiasts and for some specific tasks.

Thus, the LAN controller model is specified mainly in cases where it is a rather advanced solution that is noticeably superior to standard models. Such solutions are currently produced mainly under the brands Intel(middle level), Realtek(relatively simple models), Aquntia and Killer(mostly advanced solutions).

CPU power

The type of connector for powering the processor installed on the motherboard.

Most modern boards use a 4-pin connector, and most power supplies in ATX cases are also designed for it. In addition, there are other types of power connectors, they all have an even number of pins — 2, 6 or 8. Two-pin power is used mainly in motherboards of miniature form factors like thin mini-ITX, designed for low-power processors. 8-pin connectors, on the contrary, are designed to power the most powerful modern processors. It is believed that such a connector provides a more stable power supply and more precise tuning of its parameters. But connectors for 6 pins are not found separately, they usually complement 8-pin connectors in high-performance motherboards, in particular, gaming ones.

Also note that some boards have 2 or even 3 power connectors — most often in the format 8 + 4, 8 + 8 and 8 + 8 + 6 pins. This functionality is designed for high-end CPUs with high power and power consumption, for which one connector is not enough. There is another specific option — “motherboards” without a separate processor power supply : these are models equipped with an integrated CPU, which receives energy through its own board circuits without a sp...ecial power connector.
