Intel

QuickPath Interconnect for 4.8 and 6.4 GT/s

The applicability of this section applies to Intel

Itanium

Processor 9500 Series. This

section contains information for slow boot up speed (1/4 frequency of the reference

clock), 4.8 GT/s, and 6.4 GT/s, for Intel

QPI and Intel

SMI.

For Intel

QPI slow boot up speed, the signaling rate is defined as 1/4 the rate of the

system reference clock. For example, a 133 MHz system reference clock would have a

forwarded clock frequency of 33.33 MHz and the signaling rate would be 66.67 MT/s.
