Chapter 3: Motherboard Information
DIMM Socket (DIMM1/DIMM2): The 240-pin DDR3 DIMM is for connecting the DDR3 1333/1600
memory. The system can support up to 16 GB in maximum with dual channel configuration. To activate
dual channel, insert memory in both DIMM1 and DIMM2 slot:
SATA Connector (SATA1/SATA2, SATA6G_1, SATA6G_2): It is for connecting a SATA hard disk to
be served as your system's storage. The system can accommodate 2 disk2 (2.5) with SATA Revision 2.0
(SATA1 and SATA2) and 3.0 standard (SATA6G_1, SATA6G_2). The controller contains two modes
of operation—a legacy mode using I/O space, and an AHCI mode using memory space. Software that uses
legacy mode will not have AHCI capabilities. The AHCI (Advanced Host Controller Interface) is a
programming interface which defines transactions between the SATA controller and software and enables
advanced performance and usability with SATA. Platforms supporting AHCI may take advantage of
performance features such as no master/slave designation for SATA devices—each device is treated
as a master—and hardware-assisted native command queuing. AHCI also provides usability enhancements
such as Hot-Plug.
Note: 1. You will need to configure your SATA as AHCI mode in the BIOS in order to use the
advanced features of SATA. To do this, access the BIOS menu under IntelRCSetup-> South
Bridge Chipset Configuration->SATA Configuration. 2. Also, the hotplug enable/disable option is under the
same SATA Configuration menu. Enable the hotplug function explicitly in this menu if you need it.
