BIOS Setup Utilities Option Values: N/A 6.4 GT/s 7.2 GT/s 8.0 GT/s Unknown GT/s Help Text: Comments: Information only. Displays current frequency at which the QPI Links are operating. Appears only on multi-socket boards. When a multi-socket board has only one processor installed, QPI Link Frequency will be shown as "N/A". 12. Intel® QPI Frequency Select Option Values: Auto Max 6.4 GT/s 7.2 GT/s 8.0 GT/s Help Text: Allows for selecting the Intel® QuickPath Interconnect Frequency. Recommended to leave in [Auto Max] so that BIOS can select the highest common Intel® QuickPath Interconnect frequency. Comments: Lowering the QPI frequency may improve performance per watt for some processing loads and on certain benchmarks. [Auto Max] will give the maximum QPI performance available. Appears only on multi-socket boards. When a multi-socket board has only one processor installed, this will be grayed out, with the previous value remaining displayed. Changes in QPI Link Frequency will not take effect until the system reboots, so this will not immediately change the QPI Link Frequency display. Changing QPI Link Frequency does not affect the QPI Link Speed. 13. Intel® Turbo Boost Technology Option Values: Enabled Disabled Help Text: Intel® Turbo Boost Technology allows the processor to automatically increase its frequency if it is running below power, temperature, and current specifications. Comments: This option is only visible if all processors installed in the system support Intel® Turbo Boost Technology. In order for this option to be available, Enhanced Intel® SpeedStep® Technology must be Enabled. 14. Enhanced Intel SpeedStep® Tech 76 Intel® Server System R2000IP Service Guide
