Serial ATA Support

The board provides two 6.0 Gb/s Serial ATA (SATA) channels (blue connectors) and four 3.0 Gb/s SATA channels (black connectors). The four 3.0 Gb/s SATA channels support the following RAID (Redundant Array of Independent Drives) levels:
• RAID 0 – data striping
• RAID 1 – data mirroring
• RAID 0+1 (or RAID 10) – data striping and data mirroring
• RAID 5 – distributed parity

Audio

• Independent multi-streaming 8-channel (7.1) audio and 2-channel audio subsystem, featuring:
                   ― Intel® High Definition Audio interface
                   ― RealTek* ALC892 codec
• HD Audio front panel header
• Onboard 3-pin S/PDIF output header and back panel optical S/PDIF output connector

Expansion Capabilities

 

• Three PCI Express 3.0 x16 connectors (two x16 electrical and one x8 electrical)
• Two PCI Express 2.0 x1 connectors
• One PCI* bus connector

Legacy I/O Support

Nuvoton* Legacy I/O Controller that provides Consumer Infrared (CIR) support

3960X Extreme Edition CPU front and read views

Intel® Desktop Board DX79SI Complete.  Note how the board is well laid out with standardized Blue and Black DIMM sockets denoting the primary and secondary memory channels.    Ample cooling covering both the Southbridge and PCH Controller by heatpipe cooling solution.  We also see very clearly the dual clamps that are now used to secure the CPU in place.   As always the bottom of the mainboard has the full array of pins plugs and sockets for those additional extra’s the end-user wishes the mainboard to support.    4 fan header points to ensure that the system stays nice and cool.

Upon the CPU socket we see very clearly which mode of removal the new style clamping mechanism must be followed in opening and closing once the transit cover is removed and the CPU is inserted.    A word of caution though, ensure you know just how high your memory modules will sit on the mainboard when finally mounting your new air solution CPU cooling array.

SATA ports and South Bridge in their standard positions, though Intel have taken the trouble to ensure that the cooling solution is slick and low in profile for those long graphic cards.  We had no trouble at all with the range of cards we tested in the slots.  At the very bottom of the mainboard we see the array of LED’s for post messages and for the System Integrators  and end-users testing the system power on and reset buttons.

I/O panel standardized now and not many changes as before.  USB 3 header port clear from the main array of LAN and USB 2 ports so that there can be no confusion to what goes where.
