Option Values: Slow
Fast
Help Text: <None>
Comments: Information only. Displays current Link Speed setting for the QPI
Links. Appears only on multi-socket boards.
QPI Link Speed should display as “Slow” only when running at the “Boot Speed” of 50 MT/s,
or when a multi-socket board has only one processor installed, so QPI is not functional. It
should always be “Fast” when the QPI Link Frequency is in the normal functional range of
6.4 GT/s or above.
