Motherboard Buying Guide in Bangladesh

Motherboards are not just a simple building block of a PC. Rather, they are the foundation on which the actual building blocks stand, connect, and collaborate to perform as a single unit. From supplying and regulating the energy to different parts of a computer to passing data at a lightning speed, motherboards largely determine the strength of your PC setup. 

To ensure the most optimal performance at the expense of the least amount of energy, installing the right motherboard in your setup is pivotal. But without knowing different parts of a motherboard and their purpose, choosing one just by its name will be like buying gold, judging by its color. So, saving you from searching in the dark with the hope of accidentally finding the right motherboard, this guide will enlighten your path toward it. 

What Is a Motherboard and Why Does It Matter?

If you don’t know what motherboards are, it’s high time you learn about them. A motherboard is to a PC what a nervous system is to a biological body. Not only that, it’s also a PC’s circulatory system, and if you want to go even deeper, it’s the connective tissue system. A motherboard connects all the essential PC components, like the central processing unit, or processor, power supply, memory, storage, network card, and input and output devices.

Not only that, a motherboard has features to control how each component will respond to the others, how they will communicate, and how they will coordinate among billions and trillions of bits at a time. A motherboard’s capacity will largely determine the overall performance of your PC.

Key Features to Consider Before Buying

A full range of interconnected sockets, slots, connectors, ports, cables, and hubs comes attached to a motherboard. In most cases, these are undetachable and come in different capacities and adjustment levels. For any damage or upgrades, they can’t be replaced unit-wise. Instead, you have to buy a new motherboard.

So, take special note of their details and make sure your motherboard particles match the processor, memory, and power supply in version and demand.

CPU Socket

A CPU socket holds the processor and connects it to the other parts of the system. You can easily detect a CPU socket on a motherboard by its square-shaped mount and a retention lever hooked to it. The mount is where the processor sits, and the lever presses the chip onto the mount with the right amount of pressure. By structure, CPU sockets fall into three major categories:

Land Grid Array (LGA): Mostly common in INTEL motherboards, these sockets comprise one or two beds of tiny pins protruding from the board’s surface. A processor chip with a flat contact pad lies on the pins, which supply sufficient power for efficient processing operations. You can get the pin count of your socket from its model. For example, an LGA 2000 CPU socket has 2000 pins.

Pin Grid Array (PGA): Mostly common in AMD motherboards, PGA sockets feature a perforated bed. The pins, this time, come with the processor chip to adjust in the holes of the socket bed.

In addition, every CPU socket extends into a platform to become a mount for a heat-sync mechanism. Look into your processor’s capacity and requisites, and find a CPU socket that conforms and supplies.

Memory Slots

Two to four parallelly placed slots, usually placed close to the CPU socket, where you stick RAM modules. Often mentioned as DIMM slots, they maintain a high data transfer rate between the CPU and the RAM. Memory slots are of two types:

• DDR4: These slots have been common in previous generations of motherboards and are mostly obsolete for the latest configurations. On average, they maintain a data transfer rate of 1600 MT/s to 3200 MT/s.

• DDR5: As cutting-edge processors have higher execution capacity, they require and deliver massive amounts of data at a time. Satiating the need, DDR5 slots maintain a data transfer rate from 4800 MT/s to 8000+ MT/s. They are also more energy-efficient than DDR4 slots.

It’s notable that you can’t use a DDR4 system to run DDR5-compatible hardware, and vice versa. 

SATA Connector

Serial Advanced Technology Attachment (SATA) connectors are multipurpose parts of a motherboard’s BUS system. They have two types:

• SATA Data Connector: Connects Hard Disc Drives (HDDs), Solid State Drives (SSDs), and different optical data storage systems, like Disc Drives (DVD/CD drives), and transfers data one bit at a time.

• SATA Power Connector: Wider and robust than data connectors, and connects the power supply to the motherboard.

Expansion Slots

The reason behind the name of expansion slots is derived from their general purpose. They let users install external drives and connect those drives to expand the ability of the motherboard. 

Platform Controller Hub (PCH)

It’s a square or partially rectangular-shaped chipset, soldered to the motherboard. PCH controls and directs the data transfer between the external or integral peripheral drives and the CPU.

I/O Panel

The hub of ports and connectors that allows you to connect the motherboard to different peripheral output and input devices, like a monitor, speaker, internet source, and external data storage. An I/O panel may hold:

• Universal Serial Bus (USB)

• VGA

• HDMI

• Network Interface Card

• Integrated Sound Card

• Integrated Video Adapter

Size/Form Factor

Though often associated with size, a motherboard’s form factor tells a few definite aspects of its capacity and features. Let’s get into the details. A desktop motherboard can be of four distinct form factors:

ATX: Scaling 12-inch by 9.6-inch in dimension, ATX motherboards define the current standard for size and design. They feature seven expansion slots and four DIMM or memory slots. This immense capacity to adopt a range of external drivers and devices makes them a popular choice to be used in gaming and robust workstation setups.

Extended ATC or eATX: Measuring 12 inches in height and 13 inches in width, eATX is simply an extended capacity ATX motherboard. Besides having seven expansion slots, they offer up to 8 memory slots. It makes them suitable for gamers and professionals who need boosted power and efficiency.

Micro ATX: Its width resembles that of ATX boards but differs due to its 2.4-inch shorter height. To compensate for the size, the number of expansion slots has been reduced to two full-sized slots. They will be a great choice where portability and compactness are concerned.

Mini-ITX: The utmost compact motherboard option: only 6.7 inches wide and 6.7 inches long. May feature a maximum of one expansion slot and two memory slots. Suitable when only basic processing and output are expected.
