Frequently Asked Questions

Would enabling all my processor’s cores damage my computer? 

Enabling all the processor cores on your computer means forcing all its cores to come alive and to be in use. Doing this, therefore, does not damage your computer’s processor or affect its strength. Even though your processor stays largely unaffected, your computer’s performance may be affected as it can lead to quick battery drain and reduced app optimization.

What effect does booting with additional cores have on my computer system? 

Using all processor cores during booting usually does not affect the booting speed, time, or process. Also, most Windows use all available cores for booting and other operational processes, which most times is not all the cores that the processor has. Therefore increasing the number of cores on a processor to increase boot time or hasten the process is not entirely ideal.
