[. . . ] The value will be limited to CPU-based or factory settings. Adjusting the CPU Ratio value will change CPU Performance Settings. Use the <+> and <-> keys to adjust the value. The values range from 12 to 57 with 1 interval. [Values 12~32] Presets Enhanced Intel SpeedStep Technology and Turbo Mode to • [Disabled] but can be adjusted. Turbo Mode Parameters settings is limited to CPU Core Current Limit. • [Values 33~57] Resumes full adjustment for Turbo Mode Parameters but disallows configuration for Turbo Mode. Enhanced Intel SpeedStep Technology® [Enabled] Enhanced Intel SpeedStep Technology® allows the system operation system to dynamically adjust processor voltage and cores frequency, which can result in decreased average power consumption and decreased average heat production. Configuration options: [Disabled] [Enabled] Turbo Mode [Enabled] It automatically allows processors cores to run faster than the base operating frequency if it’s operating below power, current, and temperature specification limit. Configuration options: [Disabled] [Enabled] Turbo Mode Parameters Long Duration Power Limit [Auto] This item is Power Limit 1 in Watts. Default setting of this item is TDP (130W). For Sandy Bridge-E, Turbo Ratio can be kept a time duration exceeding TDP for maximum performance. [Manual Mode] Allows you to set a fixed VCCSA CPU voltage. [Offset Mode] Allows you to set the VCCSA Offset voltage. CPU VCCSA Manual Voltage [Auto] This item appears only when you set the CPU VCCSA Voltage item to [Manual Mode] and allows you to set a fixed CPU VCCSA voltage. The values range from 0. 800V to 1. 700V with a 0. 005V interval. Offset Mode Sign [+] This item appears only when you set the CPU VCCSA Voltage item to [Offset Mode]. [+] To offset the voltage by a positive value. [–] To offset the voltage by a negative value. CPU VCCSA Offset Voltage [Auto] This item appears only when you set the CPU VCCSA Voltage item to [Offset Mode] and allows you to set the VCCSA offset voltage. The values range from 0. 005V to 0. 635V with a 0. 005V interval. Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage may damage the CPU permanently, and setting a low voltage may make the system unstable. ASUS P9X79-E WS 3-21 DRAM Voltage (CHA, CHB) [Auto] DRAM Voltage (CHC, CHD) [Auto] Allows you to set the DRAM voltage. The values range from 1. 20V to 1. 99V with a 0. 005V interval. The values range from 1. 20V to 1. 99V with a 0. 005V interval. According to Intel CPU spec, DIMMs with voltage requirement over 1. 65V may damage the CPU permanently. [. . . ] Ensure that the cards are properly seated on the slots. Align and firmly insert the 4-Way SLI bridge connector to the goldfingers on each graphics card. Ensure that the connector is firmly in place. Connect four independent auxiliary power sources from the power supply to the four graphics cards separately. [. . . ]
