ECS Elitegroup X79R-AX [6/92] Chipset

Introducing the Motherboard

Feature

• Accommodates Intel

Sandy Bridge-E processor

• Supports “Hyper-Threading” technology CPU

• Four PCI Express x16 Gen 3 ports supporting up to 8 GB/s data transport

bandwidth (the second and the forth runs at x8 mode)

“Hyper-Threading” technology enables the operating system into thinking

it’s hooked up to two processors, allowing two threads to be run in parallel, both

on separate “logical” processors within the same physical processor.

The motherboard uses an LGA2011 type of socket that carries the following

features:

Processor

Chipset

• Supports DDR3 2400(OC)/2133(OC)/1866(OC)/1600/1333/1066 DDR3

SDRAM with four-channel architecture

• Accommodates four unbuffered DIMMs

• Up to 16 GB per DIMM with maximum memory size up to 64 GB

Memory

The Intel

X79 Chipset is a single-chip with proven reliability and performance.

• Support two PCI Express x1 slots

• Integrated four SATA 3Gb/s and six SATA

6Gb/s (include four SAS

/SATA

6Gb/s ports) Host Controllers

• Ten USB 2.0 ports supported

• Serial Peripheral Interface (SPI) support

• Intel

High Definition Audio Controller

Extra Chips

• Two ASM1061 Chips

integrate two EXSATA 6Gb/s Host Controllers and

two eSATA 6Gb/s Host Controllers

• Two Ti Chips, Ti TUSB7340 supports the four USB 3.0 ports at the rear

I/O, Ti TUSB7320 supports the Front USB 3.0 header (two ports)

*2.Only the X79R-AX has these chips.

*1.Due to chipset limitation, the compatibility and stability of SATA port

(SAS6G1_2/3_4) may differ by different devices.
