Intel 5520 IOH supports 4.8 GT/s, 5.86 GT/s, and 6.4 GT/s frequencies for the QPI links.
During QPI initialization, the BIOS configures both endpoints of each QPI link to the same
supportable speeds for the correct operation.
During memory discovery, the BIOS arrives at a fastest common frequency that matches the
requirements of all components of the memory system and then configures the DDR3 DIMMs
for the fastest common frequency.
In addition, rules on the following tables also decide the global common memory system
frequency.
