This sub-menu configures North Bridge features and shows configuration information.

This submenu configures Intel VT-d and Intel I/OAT in your system and configures IOU PCIe port bifurcation controls.

This setting allows you to Enable or Disable Intel Virtualization Technology for in your system.

This setting allows you to Enable or Disable Intel I/O Acceleration Technology in your system.

This setting allows you to Enable or Disable DCA support in your system.

Both IOH 0 and IOH 1 PCIe port bifurcation controls are available to set IOU Link Speed and PCIe Port settings. Options include Gen 1, Gen 2 or Gen 3 link speed settings or various port PCIe settings for x4x4, x8, x4x4x4, x4x4x8, x8x4x4, x8x8 or x16 (default depends upon setting).

This submenu statically displays Current QPI Link Speed and Current QPI Link Freq as well as providing options for Isoc, QPI Link Speed Mode and QPI Link Frequency Select.

This setting allows you to Enable or Disable Isoc in your system.

This setting allows you to select QPI Link Speed as being either Fast or Slow mode.

This setting allows you to select the QPI link frequency. Options include Auto, 6.4 GT/s, 7.2 GT/s or 8.0 GT/s.

This submenu displays static Memory Configuration information (Current Memory Mode, Current Memory Speed, Mirroring and Sparing), DIMM Information and other option settings.

DIMM presence and size information is shown in this submenu when selected.

This setting sets the system memory mode. Options include the following:

•Independent (default) – All DIMMs are available to the operating system.

•Mirroring – The mainboard maintains two identical copies of all data in memory for redundancy.

•Lock Step – The mainboard uses two areas of memory to run the same set of operations in parallel.

•Sparing – A preset threshold of correctable errors is used to trigger fail-over. The spare memory is put online and used as active memory in place of the failed memory.

This setting allows you to select DRAM RAPL Mode for your system. Options include Disabled, DRAM RAPL Mode0 and DRAM RAPL MODE1.

This setting allows you to force DDR speed for your system. Options include Auto, Force DDR3 800, Force DDR 1066, Force DDR 1333, Force DDR 1600 and Force SPD.

This setting allows you to select different channel interleaving settings. Options include Auto, 1 Way, 2 Way, 3 Way and 4 Way.
