DIMM Socket (J2/J3/J4/J5): The 240-pin DDR3 DIMM is for
connecting the DDR3 1066/1333/1600 (unbuffered
ECC or non-ECC) memory. The system can support
up to 32 GB in maximum. A DDR3 module has the
same physical dimensions as a DDR2 DIMM but the
notch on the pins is positioned differently. Channel
information lists below:
J2 Channel A DIMM0 (blue)
J3 Channel A DIMM1 (black)
J4 Channel B DIMM0 (blue)
J5 Channel B DIMM1 (black)
Note: Since the system is capable of Dual
Channel Architecture, some installation
guidelines have to be met to enable Dual
Channel mode as directed. To insert two DIMMs
on the system, insert DIMMS on slot J2 (blue)
and J4 (blue). And use slot J3 (black) and J5
(black) if more slots are required. (Use slot J3
and then slot J5 in sequence for the additional
DIMMS.)
SATA 1, 2 and 3, 4 Connectors (SATA1/SATA2/SATA3/
SATA4): It is for connecting a 2.5’’ SATA harddisk to
be served as your system’s storage. The system can
accommodate up to 2 disks (2.5" or 1disk for 3.5")
in maximum. SATA1 and SATA2 comply fully with
SATA Revision 3.0 standard with data transfer rates
of up to 6.0 Gb/s. SATA3 and SATA4 support SATAT
revision 2.0. 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 you will need to configure
your SATA as AHCI or RAID in the BIOS.
Note:
To configure your Hard disk using the 1.
integrated RAID feature, the Intel®Rapid
Storage Technology Utility has to be installed
on your Operating System.
You will need to select the RAID mode in the 2.
BIOS for your SATA drives first. There is also a
Clear CMOS jumper (J8): It is for clearing the CMOS
memory and system setup parameters by erasing
the data stored in the CMOS RAM such as the
system passwords.
CompactFlash Connector (CF1): It is for connecting a
Compact Flash card to be served as your system’s
storage. The connector is a CF Type II slot which could
fit both CF Type I or CF Type II cards.
