What is the case with old format expansion slots?

M.2 and U.2


is a small design that can be used to fit smaller expansion units (16-110mm long) that include NVMe (non-volatile memory express) solid-state drives Intel(r) Optane(tm) memory Wi-Fi cards, and various other devices.

M.2 devices come with distinct "keys" (the layout of silver connectors on the back) which determine compatibility with the motherboard's socket. While they may use various interfaces, most popular M.2 cards utilize the four PCIe low-latency data lane or the more traditional SATA bus.

Since M.2 cards are comparatively tiny, they offer an easy way to increase capacity of storage or system capabilities within a smaller system. They are directly connected to the motherboard, cutting out the cables required with the traditional SATA-based devices.


connectors are a different interface that connects 2.5" SSDs using PCIe cables. U.2 SSDs are typically employed in professional settings, such as data centers or servers, although they are less commonly used in consumer build.

U.2 as well as M.2 both have the identical amount of PCIe lanes and have similar speeds, however U.2 allows hot swapping (meaning that the drive can be removed while the computer running it is on) and has the ability to support different power options than M.2.

SATA (Serial ATA) is an older computer bus , less often used today for connecting to 2.5" as well as 3.5" HDDs, SSD drives as well as optical drives which play DVDs as well as Blu-ray. Check out dell 3558 motherboard price online In India.

Although slower than PCIe however, the SATA 3.0 interface can support speeds of data transfer up to 6Gbit/s. The more recent SATA Express (or SATAe) format utilizes two PCIe lanes in order to achieve speeds of 16Gbit/s. The format isn't to be confused with External SATA (eSATA), an external port that permits the access to (compatible) portable hard drives.

Motherboards can also accommodate RAM modules, which are memory sticks that temporarily store information for rapid retrieval. Multiple RAM sticks with high-speed speeds helps PCs run simultaneous programs with no lag.

Full-sized motherboards (like the ATX form aspect) typically come with four slots, whereas smaller-sized boards such as mITX typically utilize two. But, motherboards with HEDT such as those that are compatible with models that use the Intel(r) Core(tm) the X-series processor family (as as servers/workstation motherboards that are based upon the Intel(r) Xeon(r) platform) could have as many as eight slots.

Recently, Intel motherboards are compatible with dual-channel memory technology, which means that there are two separate channels for transferring data between memory controller of the CPU and the sticks of DIMM (dual in-line memory modules) RAM. So long as RAM sticks are installed in pairs and have matching frequencies that results in speedier data transfer as well as better performance in certain applications.

  • Form Factor
  • Form element

The motherboard's form factor will determine the size of the case you'll need, the number of expansion slots to choose from, and numerous aspects related to the design of the motherboard as well as cooling. The majority of the time, bigger form factors provide builders with the ability to use more DIMM and PCIe full-size along with M.2 slots to use.

In order to make life easier for manufacturers and consumers alike Desktop motherboard dimensions are standardized. The form factors for laptop motherboards however tend to differ by the manufacturer because of the distinct dimensions of the. This is especially applicable to highly customized designed desktops.

Common motherboard forms of desktops include:

ATX (12" 9.6") 9.6")

 is the current standard for full-sized motherboards. A typical consumer ATX motherboard normally has seven expansion slots that are spaced 0.7" apart as well as the four DIMM (memory) slots.

Extended ATX or eATX (12" 13") 

The largest version in the ATX form factor specifically designed for professional and enthusiast use These boards come with extra space to allow for more flexible configurations of hardware.

Micro ATX

 (9.6" 9.6" x 9.6") Micro ATX (9.6" x 9.6"): A smaller version of ATX that comes with 2 full size (x16) slot expansions as well as 4 DIMM slot. 791129-001 Mini-towers can be incorporated, however it can be used with mounting holes found in larger ATX cases.


(6.7" x 6.7") is a small design that is intended for use in computers with small size and no fan cooling. It has a PCIe slot that is full size and usually the two DIMM slots. Mounting holes are compatible with ATX cases.

What are the six audio analog ports of my motherboard?

The motherboard could also have the S/PDIF (Sony/Philips Digital Interface) connectors, for example, optical and coaxial audio port, which work with home theater receivers and other audio equipment. This is a great alternative if your device doesn't allow audio transfer through HDMI.


The majority of consumer motherboards have the RJ45 port for LAN, which can be connected to your modem or router through an Ethernet cable. Certain motherboards have dual ports that can be used with a an antenna for Wi-Fi and advanced connectivity options such as dual 10 gigabit Ethernet ports.

What is a PCB?

It is helpful to be aware of some basic terms related to the manufacturing of motherboards, as manuals and ads from manufacturers frequently refer to their PCB manufacturing methods. design and construction.

Modern motherboards are printed circuit board (PCB) comprised of fiberglass layers and copper, along with other components attached to it or embedded into it.

Modern PCBs typically have about 10 layers, which makes them far more tightly connected than they appear on the outside.

Every conductor "trace" is the lines that appear on the board's surfaceeach trace is an individual electrical connection. In the event that one of these trace gets broken, then the circuit will be not complete and motherboard components stop working correctly. For instance, if a trace that connects an PCIe connection to the PCH has been severely damaged The PCIe slot could not be able to power the expansion card that is installed in it.

When conductive traces are made through chemical etching, the manufacturers apply the solder mask, typically a green polymer layer which helps to prevent the oxidation. It also assists in preventing damaging the handling surface, making sure that the trace won't be damaged through a tiny bump or scratch as you put the motherboard in its case.
