Chapter 1 <Introduction>

1.1 <Product Overview>

LV-6714 is a Mini-ITX Motherboard which supports Alder Lake/12th Gen Desktop

Processors, integrated DDR5 memory, Realtek High DefinitionAudio, Intel Gigabit LAN,

USB3.2 Gen2, SATA3 with AHCI function for a system.

New feature for Alder Lake

Alder Lake/12th Gen Processors are based on the 7nm SuperFin process, and offer

long-life availability. i9-12900 with 8 P-cores and 8 E-cores. P-cores can help you handle

heavy tasks, and E-cores run background tasks efficiently to save power. Support DDR5

Memory up to 4800 and PCIe gen 5 x16 Slot.

All in One multimedia solution

The board provides one M.2 3042 slot (support SATA), one M.2 2230 slot, one M.2 2280

slot (PCIe Gen4), and one PCIe x16 slot (PCIe Gen5 X16).

Alder Lake support Windows10 version 21H2 64bit and Linux 5.18

Intel recommends using Windows 10 version 21H2 64bit. It may lose some drivers if you

use other Windows version.
