500 Series BIOS Manual
DLLBwEn
Allows you to set the DLLBwEn value. Select values 2 to 4 for best Memory
overclocking. Conguration options: [Auto] [0] – [7]
Legacy Mode
Conguration options: [Disabled] [Enabled]
SPD Write Disable
Allows you to enable or disable setting SPD Write Disable. For security recommendations,
SPD Write Disable bit must be set. Conguration options: [TRUE] [FALSE]
DIGI+ VRM
Changing the values in this menu may cause the system to become unstable! If this
happens, revert to the default settings.
CPU Load-line Calibration
The load-line is dened by the Intel VRM specication and affects the level of voltage
supplied to the processor. Higher load-line calibration settings result in reduced
VDroop at the expense of voltage overshoot and will increase CPU temperature due to
higher voltage under load. Select from Level 1 to 7 to adjust the load-line slope. Level
1 represents greater VDroop, and Level 7 minimum VDroop.
Conguration options: [Auto] [Level 1] [Level 2] [Level 3] [Level 4:Recommended for DC]
[Level 5] [Level 6] [Level 7]
The actual performance boost may vary depending on your CPU specication.
DO NOT remove the VRM heatsink.
Synch ACDC Loadline with VRM Loadline
When this item is set to [Enabled], VRM Loadline will be adjust automatically to match
AC/DC Loadline. Conguration options: [Disabled] [Enabled]
CPU Current Capability
This item allows you to set the shut-off current limit for external voltage regulator. A
higher setting will allow the voltage regulator to supply more current while a lower
setting will cause the voltage regulator to shut off the system when the supplied current
is higher than the set value. Conguration options: [Auto] [100%] [110%] [120%]
[130%] [140%] [150%] [160%] [170%]
Congure higher values when overclocking or when using higher current demanding stress
tests.
