Advanced settings
On some computer models, the

disable HyperThreading. This feature works only with HyperThreading-aware
operating systems, such as Windows Vista and Windows XP. The default setting
for HyperThreading is
Enabled . However, if you select Set Defaults and are using
an operating system other than Windows Vista or Windows XP, your computer
performance might be degraded. Therefore, you should always set
HyperThreading to
Disabled unless you are sure your operating system supports
HyperThreading.

After you finish viewing or changing settings, press Esc to return to the Setup
Utility program menu (you might have to press Esc several times). If you want to
save the new settings, select

changes will not be saved.
