18. Active Processor Cores

Option Values:

All

Help Text:

Number of cores to enable in each processor package.

Comments: The numbers of cores that appear as selections depends on the

number of cores available in the processors installed. Boards may have as many as 8 cores in

each of 1, 2, or 4 processors. The same number of cores must be active in each processor

package.

This Setup screen should begin with the number of currently-active cores as the number

displayed. See note below – this may be different from the number previously set by the

user.

Note

: The ME can control the number of active cores independently of the BIOS Setup

setting. If the ME disables or enables processor cores, that will override the BIOS setting,

and the number selected by BIOS will be disregarded.
