Description

 

 

 

When enabled, In-System Characterization (ISC)

 

executes during POST upon detecting relevant

 

change(s) in system configuration. This helps in

 

optimizing the system power and performance.

 

ISC takes about 20 seconds to execute, and system

 

reset is required for ISC results to be applied. The

 

Enabled - No Reboot option executes ISC and

 

continues without applying ISC results until the

 

next time system reset occurs. The Enabled option

 

executes ISC and forces an immediate system

 

reset so that ISC results can be applied. It takes the

 

system longer to be ready due to the forced

 

system reset. When disabled, ISC does not execute.
