Acoustic Noise Mitigation
Enabling this option will help mitigate acoustic noise on certain SKUs when the CPU is in
deeper C state
Pre Wake Time
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
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
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 IA Domain
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 stat.

Slow Slew Rate for IA Domain
Set VR IA Slow Slew Rate for Deep Package C State ramp time; Slow slew rate equals to Fast
divided by number, the number is 2, 4, 8, 16 to slow down the slew rate to help minimize acous-
tic noise
Disable Fast PKG C State Ramp for GT Domain
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 GT Domain
Set VR GT Slow Slew Rate for Deep Package C State ramp time; Slow slew rate equals to Fast
divided by number, the number is 2, 4, 8 to slow down the slew rate to help minimize acoustic
noise; divide by 16 is disabled.
