CPU Socket

The CPU socket is one of the most critical components on a motherboard. It determines the type of processor the motherboard supports. Modern motherboards typically feature LGA (Land Grid Array) or PGA (Pin Grid Array) sockets for Intel and AMD processors, respectively.

Socket	Compatible Processors
LGA 1700	Intel 12th & 13th Generation Core
LGA 1200	Intel 10th & 11th Generation Core
AM5	AMD Ryzen 7000 Series
AM4	AMD Ryzen 1000 to 5000 Series

It’s essential to choose a motherboard with a socket that matches your desired processor.

Chipset

The chipset is a set of chips on the motherboard that controls the communication between the CPU, RAM, storage devices, and other peripherals. It determines the features and capabilities of the motherboard. Modern chipsets offer support for faster memory, more USB ports, advanced storage interfaces, and enhanced power management.

Examples of Modern Chipsets

The chipset you choose will impact your motherboard’s overall functionality and performance.

Memory Slots

Memory slots, also known as DIMM (Dual In-line Memory Module) slots, are where you install the RAM modules. Modern motherboards usually have four memory slots, supporting dual-channel or quad-channel memory configurations. The number of slots and the maximum supported memory capacity vary depending on the motherboard.

DIMM Slots	Max Memory Capacity	Memory Type
4	Up to 128GB	DDR4, DDR5
2	Up to 64GB	DDR4, DDR5

Modern motherboards support DDR4 or the newer DDR5 memory standard, offering faster speeds and higher capacities.

Expansion Slots

Expansion slots allow you to add various components to your motherboard, such as graphics cards, sound cards, network cards, and more. The most common expansion slots on modern motherboards are PCIe (Peripheral Component Interconnect Express) slots.

PCIe Slot Configurations

• PCIe x16: Used for graphics cards and high-performance peripherals
• PCIe x8: Used for high-speed devices like NVMe SSDs or dual graphics cards
• PCIe x4: Used for devices like Wi-Fi cards, capture cards, or NVMe SSDs
• PCIe x1: Used for low-bandwidth devices like sound cards or USB expansion cards

Modern motherboards often include multiple PCIe slots to support various configurations and expandability options.

Storage Interfaces

Storage interfaces on modern motherboards allow you to connect various storage devices, such as hard drives, SSDs, and NVMe drives. The most common storage interfaces are SATA and M.2.

SATA (Serial ATA)

SATA is the standard interface for connecting hard drives and SSDs. Modern motherboards typically include 4-8 SATA ports, supporting SATA 3.0 (6 Gbps) speeds.

M.2

M.2 is a newer interface designed for small form factor SSDs. It offers faster speeds and lower latency compared to SATA. Modern motherboards often have 1-3 M.2 slots, supporting PCIe 3.0, PCIe 4.0, or PCIe 5.0 speeds.

Interface	Max Speed	Compatible Devices
SATA 3.0	6 Gbps	Hard Drives, SATA SSDs
M.2 PCIe 3.0	32 Gbps	NVMe SSDs
M.2 PCIe 4.0	64 Gbps	NVMe SSDs
M.2 PCIe 5.0	128 Gbps	NVMe SSDs

USB Ports

USB (Universal Serial Bus) ports are essential for connecting various peripherals, such as keyboards, mice, external storage devices, and more. Modern motherboards include a mix of USB 2.0, USB 3.2 Gen 1, USB 3.2 Gen 2, and USB 4 ports.

USB Port Types and Speeds

• USB 2.0: Up to 480 Mbps
• USB 3.2 Gen 1 (USB 3.0): Up to 5 Gbps
• USB 3.2 Gen 2: Up to 10 Gbps
• USB 3.2 Gen 2×2: Up to 20 Gbps
• USB 4: Up to 40 Gbps

Modern motherboards often include a combination of USB port types to support a wide range of devices and speeds.

Networking

Modern motherboards include built-in networking capabilities, allowing you to connect your computer to a local network or the internet. The most common networking features are Ethernet and Wi-Fi.

Ethernet

Ethernet ports on modern motherboards support Gigabit Ethernet (1 Gbps) or 2.5 Gigabit Ethernet speeds. Some high-end motherboards even offer 5 Gbps or 10 Gbps Ethernet for faster wired networking.

Wi-Fi

Many modern motherboards come with built-in Wi-Fi, supporting the latest wireless standards like Wi-Fi 6 (802.11ax) or Wi-Fi 6E. This allows for fast and convenient wireless networking without the need for an additional Wi-Fi card.

Audio

Audio is an essential component of modern motherboards, providing high-quality sound output for music, movies, and games. Most motherboards include a built-in audio codec, supporting multi-channel audio and various audio connectors.

Common Audio Features

• Realtek ALC1200 or ALC1220 audio codec
• Support for 7.1 or 5.1 Surround Sound
• Optical S/PDIF output for digital audio
• Audio capacitors and shielding for improved sound quality

Some high-end motherboards even offer dedicated audio components and software enhancements for an immersive audio experience.

Power Delivery

Power delivery is a crucial aspect of modern motherboards, ensuring stable and reliable Power Supply to the CPU, RAM, and other components. The power delivery system consists of the VRM (Voltage Regulator Module) and power connectors.

VRM

The VRM is responsible for converting the 12V power from the power supply to the appropriate voltage levels required by the CPU and other components. Modern motherboards often feature robust VRMs with multiple power phases for stable power delivery and better overclocking potential.

Power Connectors

Modern motherboards include various power connectors to supply power to different components:
