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.

Lighting sync

Synchronization technology provided in the board with LED backlight (see above).

Synchronization itself allows you to "match" the backlight of the motherboard with the backlight of other system components — cases, video cards, keyboards, mice, etc. Thanks to this matching, all components can change colour synchronously, turn on / off at the same time, etc. Specific features the operation of such backlighting depends on the synchronization technology used, and, usually, each manufacturer has its own (Mystic Light Sync for MSI, RGB Fusion for Gigabyte, etc.). The compatibility of the components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to collect components from the same manufacturer.

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.

DDR5

The number of slots for DDR5 RAM, provided in the motherboard.

DDR5 is being introduced to replace the fourth version of the DDR standard from the end of 2020. It provides for approximately a twofold increase in memory subsystem performance and increased bandwidth compared to DDR4. Instead of a single 64-bit data channel, DDR5 uses a pair of independent 32-bit channels that work with 16-byte packets and allow 64 bytes of information to be delivered per clock on each channel. New memory modules require a voltage of 1.1 V, and the maximum volume of one DDR5 bar can reach an impressive 128 GB.

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.

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.

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.

Optical S/P-DIF

Output for sound transmission, including multi-channel, in digital form. Such a connection is notable for its complete insensitivity to electrical interference, since an optical cable, rather than an electrical cable, is used to transmit the signal. The main disadvantage of optical S / P-DIF, in comparison with coaxial, is a certain fragility of the cable — it can be damaged by strongly bending or stepping on it.
