Functional Description
ATCA-8310 Installation and Use (6806800M72E) 79
4.3.1.1 Thermal Monitor
The Arrandale+ECC provides integrated "Adaptive Intel Thermal Monitor and Digital Thermal
Sensor" - PECI.
4.3.1.2 Chipset Connection
The connection to the chipset is done with a DMI x4 interface which is a proprietary interface
from Intel. Electrically, it is similar to PCIe.
Additionally, the graphic signals are transmitted over the Intel Flexible Display Interface to the
chipset.
4.3.1.3 GPP System Memory
The system memory, which is directly connected to the Arrandale+ECC consists of two
channels. Unbuffered DDR3 memory with one DIMM-slot per channel is supported. The speed
grade is 800/1066.
The ATCA-8310 provides two very Low Profile (VLP) Mini-DIMM sockets to install off-the-shelf
DIMM modules. Different DIMM types must not be used at the same time. DIMM module
height is restricted.
4.3.2 Mobile Intel 5 Series Chipset
The Mobile Intel 5 Series Chipset is available in different flavours. Two of which are suitable for
the Arrandale+ECC platform. The QM57 (Ibex Peak Mobile) is used.
4.3.2.1 PCI Express Interface of the Ibex-Peak
The Ibex-Peak provides eight PCIe lanes.
For the ATCA-8310, port 1-4 will be configured as a by 4 port to connect to the dual Gigabit
Ethernet Controller.
