6 Introduction
1.5 Functional Description
Processor Support
The EAM-400H is an industrial motherboard supporting the 3rd
generation Intel® Core™ processor family (Intel® Core™ i7/i5/i3)
in LGA1155 socket. An integrated memory controller supports
dual channel DDR3 1333/1600 MHz and Intel® HD Graphics is
integrated onboard the CPU. The CPU provides a PCI Express
x16 for external graphics or expansion. Direct Media Interface
(DMI) and Flexible Display Interface (FDI) provide connectivity to
the Intel® H61 Express Chipset.
Intel® H61 Express Chipset
The Intel® BD82H61 Platform Controller Hub (PCH) combines
with the processor to provide a compact yet powerful 2-chip solu-
tion. Direct Media Interface (DMI) is the chip-to-chip connection
between the processor and PCH. Intel® Flexible Display Interface
carries display traffic from the integrated graphics in the processor
to the legacy display connectors in the PCH. The PCH supports all
other required interfaces including PCI Express, SATA 3 Gb/s,
USB 2.0, PCI, LPC, and SPI.
Dual-Channel DDR3 Memory
To meet the requirements of memory-intensive applications, the
EAM-400H has a dual-channel memory architecture supporting
DDR3 1333/1600 MHz DIMMs. The key advantages of DDR3 are
the higher bandwidth and the increase in performance at lower
power than DDR2. DDR3 memory technology meets the require-
ments of the latest 3D graphics, multimedia, and network applica-
tion, and boosts system performance by eliminating bottlenecks.
Gigabit Ethernet
The EAM-400H utilizes two Realtek® RTL8111E Gigabit Ethernet
Controllers connected to the PCI-E bus of the H61 PCH. Wake-
on-LAN and PXE are supported.
