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.
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,
X570S,
A620,
B650,
B650E,
X670 and
X670E. 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.
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 south bridges. The key element is the northbridge, it connects the processor, mem
...ory, 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.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.
Active cooling
The presence of its own built-in
active cooling system.
Active cooling is called, in which heat is forcibly removed from a heated object and this function is usually provided with the help of fans. This solution is designed to reduce the thermal load on motherboards without external coolers, which anyway will be additionally installed.
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.
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.
