3.5.1.1

CPU Voltage Override Type

For CPU Override Type, select Static. This setting prevents dynamic adjustments that

could confuse tuning efforts. Later in the tuning procedure, the dynamic setting can

be restored if it does not result in thermal throttling of the processor.

3.5.1.2

On the CPU Voltage Override, increase the voltage setting. This needs to be done to

provide the extra voltage to support performance tuning. The amount of voltage

increase needed depends on the amount of performance increase that is desired. This

is something of a trial and error process and the objective is to provide just enough

voltage so the processor can sustain the desired level of performance. Note that high

voltage settings may potentially cause processor damage. Later in the tuning process,

this voltage will be reduced to the lowest level that provides stability.

3.5.1.3

Set CPU VReg Droop Control to Low V-droop (Performance) if you are attempting to

maximize processor performance. If you are attempting moderate performance

increases, then the Mid or the High V-droop (Power Saving) selection is acceptable.

3.5.1.4

Set the TDC Current Limit Override (Amps). The amount of additional processor

current needed depends on the amount of frequency increase being attempted and the

processor workload. The purpose of the TDC current limit is to thermally protect the
