BIOS Item Options Description
Acoustic Noise Mitigation
Enabled
Disabled
Enabling this option will help mitigate
acoustic noise on certain SKUs when the
CPU is in deeper C state
Pre Wake Time
0 Set the maximum Pre Wake
randomization time in micro ticks. Range
is 0-255. This is for acoustic noise
mitigation Dynamic Perodicity Alteration
(DPA) tuning.
Ramp Up Time
0 Set the maximum Ramp Up randomization
time in micro ticks. Range is 0-255. This is
for acoustic noise mitigation Dynamic
Perodicity Alteration (DPA) tuning.
Ramp Down Time
0 Set the maximum Ramp Down
randomization time in micro ticks. Range
is 0-255. This is for acoustic noise
mitigation Dynamic Perodicity Alteration
(DPA) tuning.
Disable Fast PKG C State
Ramp for VccIn Domain
TRUE
FALSE
This option needs to be configured to
reduce acoustic noise during deeper C
states. False: Don't disable Fast ramp
during deeper C states; True: Disable Fast
ramp during deeper C state
Slow Slew Rate for VccIn
Domain
Fast/2
Fast/4
Fast/8
Fast/16
Set VR VccIn Slow Slew Rate for Deep
Package C State ramp time; Slow slew rate
equals to Fast devided by number, the
number is 2, 4, 8, 16 to slow down the
slew rate to help minimize acoustic noise
