Heat pipes
The heat pipe is a hermetically sealed structure containing a low-boiling liquid. When one end of the tube is heated, this liquid evaporates and condenses at the other end, thus removing heat from the heating source and transferring it to the radiator. Such devices are simple and at the same time effective, so they can be easily used as an addition to radiators.
ECC
The ability of the motherboard to work with memory modules that support
ECC (Error Checking and Correction) technology. This technology allows you to correct minor errors that occur in the process of working with data, and increases the overall reliability of the system; mainly used in servers.
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.
ARGB LED strip
Connector for connecting an addressable LED strip as a decorative lighting for a computer case. This type of "smart" tape is based on special LEDs, each of which consists of an LED light and a built-in controller, which allows you to flexibly control the luminosity using a special digital protocol and create amazing effects.
RGB LED strip
Connector for connecting a decorative LED strip and other devices with LED indication. Allows you to control the backlight of the case through the motherboard and customize the glow for your tasks, including synchronize it with other components.
HDMI output
The motherboard has its own
HDMI output.
Such an output is intended for transmitting video from an integrated graphics card (see above) or a processor with integrated graphics (we emphasize that it is impossible to output a signal from a discrete graphics card through the motherboard chipset). As for HDMI specifically, it is a combined digital video/audio interface specifically designed to work with HD resolutions and multi-channel audio. Today it is the most common of these interfaces, HDMI support is almost mandatory for video devices that are compatible with HD standards.
The specific capabilities of HDMI vary by version (see below for more details), but in general they are quite impressive — even in the earliest (current today) HDMI v.1.4, the maximum resolution is 4K, and in newer standards it reaches 10K. So in motherboards, the quality of the video transmitted through such an output is often limited not by the interface capabilities, but by the graphics performance of the system.
HDMI version
HDMI connector version (see above) installed in the motherboard.
— v.1.4. The earliest of the standards found nowadays, which appeared back in 2009. Supports resolutions up to 4096x2160 inclusive and allows you to play Full HD video with a frame rate of up to 120 fps — this is enough even for 3D playback.
— v.1.4b. A modified version of v.1.4 described above, which introduced a number of minor updates and improvements — in particular, support for two additional 3D formats.
— v.2.0. Also known as HDMI UHD, this version introduced full 4K support, with frame rates up to 60 fps, as well as the ability to work with 21:9 ultra-widescreen video. In addition, thanks to the increased bandwidth, the number of simultaneously reproduced audio channels has grown to 32, and audio streams to 4. And in the v.2.0a improvement, HDR support has also been added to all this.
— v.2.1. Another name is HDMI Ultra High Speed. Compared to the previous version, the interface bandwidth has really increased significantly — it is enough to transmit video at resolutions up to 10K at 120 frames per second, as well as to work with the extended BT.2020 colour space (the latter may be useful for some professional tasks). HDMI Ultra High Speed cables are required to use the full capabilities of HDMI v2.1, but older standard features are available with regular cables.
DisplayPort
Availability of
DisplayPort output on the motherboard.
Primarily, this digital connector is used to transmit video from the built-in video card or processor with integrated graphics to external screens. Moreover, through one DisplayPort interface it is possible to connect several displays in series in a “chain” (“daisy chain” format). Specific output capabilities vary by version (see below), but even the most modest DisplayPort specification (among modern options) allows 4K at 60 fps, 5K at 30 fps, and 8K with some limitations.
The DisplayPort interface is a standard for Apple monitors and is found in screens from other manufacturers.
DisplayPort version
The version of the DisplayPort interface (see above) installed on the motherboard.
— v.1.2. The oldest version in use today (2010). It was in it that 3D support first appeared, the ability to work with the miniDisplayPort connector, as well as the option of connecting several screens in series to one port (daisy chain). The maximum resolution fully supported by v.1.2 is 5K at 30 fps, with some limitations, 8K video is also supported. And the v.1.2a update, introduced in 2013, added compatibility with the FreeSync technology used in AMD graphics cards.
— v.1.3. An update to the DisplayPort standard released in 2014. Thanks to the increase in bandwidth, it was possible to provide full support for 8K video (at 30 fps), and in 4K and 5K standards, increase the maximum frame rate to 120 and 60 fps, respectively. Another key update was the Dual-mode function, which provides compatibility with HDMI and DVI interfaces through the simplest passive adapters.
— v.1.4. The most recent version of the widely used. The bandwidth has been further increased (almost doubled compared to v.1.2, which allowed, albeit with some limitations, to transmit 4K and 5K video at up to 240 fps and 8K at up to 144 fps. In addition, Support for a number of special features has been added, including HDR10, and the maximum number of simultaneously transmitted audio channels has increased to 32.
