SVID Behavior
Allows you to program the CPU’s SVID behavior based on the CPU’s quality. The default
option is based on
[Typical Scenario]
, but the more optimistic the mode selected, the lower
the temperature of the CPU.
[Intel’s Fail Safe]
is the default behavior of the processor
oblivious to the actual Motherboard design.
[Trained]
optimizes SVID behavior to match
input parameters such as VRM Loadline and Target Frequencies.
Configuration options: [Auto] [Best-Case Scenario] [Typical Scenario] [Worst-Case Scenario]
[Intel’s Fail Safe] [Trained]
BCLK Frequency : DRAM Frequency Ratio
[Auto]
The BCLK frequency to DRAM frequency ratio will be set to the optimized
setting.
[100:133]
The BCLK frequency to DRAM frequency ratio will be set to 100:133.
[100:100]
The BCLK frequency to DRAM frequency ratio will be set to 100:100.
Memory Controller : DRAM Frequency Ratio
BCLK Frequency: DRAM Frequency Ratio of 100:133 tends to overclock better and 1:2
Memory Controller: DRAM Frequency Ratio only works with even numbered DRAM Ratios
and not odd numbered ratios.
Configuration options: [Auto] [1:1] [1:2] [1:4]
DRAM Frequency
Allows you to set the memory operating frequency. The configurable options vary with the
BCLK (base clock) frequency setting. Select the auto mode to apply the optimized setting.
The configuration options for this item vary depending on the DIMM model you installed on
the motherboard.
The frequency ratios in gray are not recommended, use BCLK + ratios in white to reach
your target frequency if needed.
DIMM Flex
Enable to configure DRAM Timings and Frequencies based on DRAM Temperature. Set this
item to
[Disabled]
to disable this feature.
Configuration options: [Disabled] [Enabled]
•
DRAM settings will remain at Level1 at BIOS boot until the handover to OS.
•
The following item appears only when
DIMM Flex
is set to
[Enabled]
.
DIMM Flex: Dynamic DRAM Temperature OC Switcher
Configure DRAM Timings and Frequencies based on DRAM Temperature.
DIMM Flex Presets
Allows you to select DIMM Flex Presets for different memory modules.
