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.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 motherb
...oards 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.
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).
PS/2
The number of PS/2 ports provided in the design of the motherboard.
PS/2 is a dedicated port designed to connect exclusively to keyboards and/or mice. The traditional motherboard configuration for a PC provides 2 such ports — for the keyboard (usually highlighted in lilac) and for the mouse (green). However, there are boards with one connector, to which you can connect any of these types of peripherals, to choose from. Anyway, the presence of PS/2 can save the user from having to occupy USB ports for the keyboard / mouse; this is especially useful if you have to deal with a lot of other USB peripherals. On the other hand, for a number of reasons, this connector is considered obsolete and is used less and less; and PS/2 peripherals are produced mainly in the form of USB devices, additionally equipped with PS/2 adapters.
