How the picks were chosen
We started with a pool of three LGA1718 motherboards from the catalog, then shortlisted based on form factor, memory type (all use DDR5), and connectivity features. We looked for boards that cover a range of uses, from compact builds to server workstations and gaming. Prices are read live from the store listing and may change; we do not quote them here. No unit was tested in our lab; the picks are based solely on the specifications and features stated in each product page.
Picking the right one for you
Check socket compatibility
LGA1718 is the physical socket for AMD's AM5 platform, which supports Ryzen 7000 series processors and later. Before buying, confirm your CPU is listed as compatible with the motherboard's socket and chipset. All boards in this guide use LGA1718, but the chipset (X870, B650, A620) determines feature support like overclocking and PCIe lanes.
Choose a form factor that fits your case
Motherboards come in ATX, micro-ATX (mATX), and mini-ITX sizes. ATX boards like the X870 AORUS Infinity offer more slots and ports but require a larger case. mATX boards, such as the ASRock Rack and GIGABYTE A620M, fit in compact cases and are easier to install in tight spaces. Measure your case interior to ensure the board will fit.
Memory type and capacity
Every LGA1718 board in this guide uses DDR5 memory. DDR5 offers higher bandwidth than DDR4, but you must pair the board with DDR5 RAM modules. Check the number of memory slots and maximum supported capacity; some boards may have fewer slots than you expect. The pool here does not specify maximum RAM, so refer to the seller's full spec sheet before purchasing.
Connectivity and expansion
Consider what you need for storage and networking. PCIe 5.0 is available on the high-end X870 board, while the A620M only supports PCIe 4.0. M.2 slots hold NVMe drives, and USB4 provides fast data transfer and display output over a single port. Wi-Fi 7 offers high throughput and low latency, but it is only present on the top pick. If you rely on wired Ethernet, check the LAN speed stated by the seller.
Questions
What is LGA1718?
LGA1718 is the physical socket used by AMD's AM5 platform. It has 1718 pins and was introduced for Ryzen 7000 series processors. All AM5 motherboards use this socket, and it supports DDR5 memory. You can identify an LGA1718 board by its socket name, which appears on the product listing.
Do all LGA1718 motherboards support DDR5?
Yes, the LGA1718 socket is designed exclusively for DDR5 memory. There is no DDR4 compatibility on AM5 boards. When building with an LGA1718 motherboard, you must purchase DDR5 RAM modules that match the board's supported speed and capacity. Check the motherboard's spec sheet for the maximum memory speed.
What is the difference between ATX and micro-ATX motherboards?
ATX boards are larger, typically 305 x 244 mm, and offer more expansion slots, PCIe lanes, and connectivity options. Micro-ATX boards are smaller, usually 244 x 244 mm, and fit in compact cases. They have fewer slots but are sufficient for most builds. Choose ATX for maximum expansion, mATX for smaller cases or simpler systems.
Do I need a discrete graphics card with these boards?
The need for a discrete GPU depends on your processor. AMD Ryzen 7000 series CPUs with integrated graphics (those ending in 'G') provide video output. Other models lack integrated graphics, so you must install a dedicated GPU. The boards themselves do not have built-in graphics; they pass video signals from the CPU or GPU to the display ports.
