PFloor Tuning
Option Values: [Entry Field maximum Non-Turbo Frequency -3 of installed Processors
12, 12 is default]
Help Text:
Adjustment of CPU idle frequency for PCIe Bus tuning.
Comments: Changing processor power state configuration may improve I/O performance. If
processor low power states (Processor C-state) appear to be involved in the I/O performance issue
experimentally, the next step is to see if establishing a minimum operating frequency resolves the
problem by setting the value of the BIOS Setup option "PFloor Tuning". This will set the minimum
operating frequency to be the same as the maximum non-Turbo frequency. The BIOS provides the
Setup option "PFloor Tuning" with allowable range between the maximum Non-Turbo operating
frequency minus 3 and 12, and the value is the number of 100 MHz step.

3. SMM Wait Timeout
Option Values: [Entry Field 20 3000ms, 20 is default]
Help Text:
Millisecond timeout waiting for BSP and APs to enter SMM. Range is 20ms to 3000ms.
Comments: Amount of time to allow for the SMI Handler to respond to an SMI. If exceeded,
BMC generates an SMI Timeout and resets the system.
Note: this field is temporary, and will be removed when no longer required.

Power & Performance
The Power & Performance screen allows the user to specify a profile which is optimized in the direction of
either reduced power consumption or increased performance.
To access this screen from the Main screen, select Advanced > Power and Performance. To move to
another screen, press the <Esc> key to return to the Advanced screen, then select the desired screen.
There are four possible profiles from which to choose. When a Power and Performance Profile is chosen, that in
turn will cause the system to implement a defined list of Setup option settings and internal (non-visible) settings.
There is an explanation displayed on the screen, because of the fact that other settings may be adjusted without
specifically notifying the user.
