Asus P8H77-I User Manual

2-15ASUS P8H77-I
The following three items appear only when you set both the Enhanced Intel SpeedStep
Technology and Turbo Mode items to [Enabled].
Long duration power limit [Auto]
The default setting of this item will be TDP (65W or 95W for different CPUs). For Sandy
Bridge, Turbo Ratio can be kept a time duration exceed TDP for maximum performance. Any
under 255 can be programmed. Use the <+> and <-> keys to adjust the value.
Long duration maintained [Auto]
This value can vary from 1 to 32, which indicates the time window for Turbo Ratio over TDP
should be maintained. Use the <+> and <-> keys to adjust the value.
Short duration power limit [Auto]
This is the second power limit to provide rapid protection when package power exceeds
Power Limit 1. Default setting is 1.25 times Power Limit 1. For Intel recommend, platform
must be capable of supporting over Power Limit 2 for up to 10 msec. ASUS board can
support over Power Limit 2 for a long duration. Use the <+> and <-> keys to adjust the value.
Primary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for CPU cores. The value is
represented in 1/8 A (0.125A) increment. Use the <+> and <-> keys to adjust the value.
Secondary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for internal graphics cores. The
value is represented in 1/8 A (0.125A) increment. Use the <+> and <-> keys to adjust the
value.
Some of the following items are adjusted by typing the desired values using the numeric
keypad and press <Enter>. You can also use the <+> and <-> keys to adjust the value. To
restore the default setting, type [auto] using the keyboard and press <Enter>.
2.4.6 CPU Voltage [Auto]
Allows you to set the CPU voltage. Conguration options: [Auto] [+0.05V] [+0.10V] [+0.15V].
2.4.7 iGPU Offset Voltage [Auto]
Allows you to set the iGPU Offset voltage. The value ranges from 0.005V to 0.635V with a
0.005V interval.
2.4.8 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.185V to 2.135V with a 0.005V
interval.
According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may damage
the CPU permanently. We recommend you install the DIMMs with the voltage requirement
below 1.65V.
