Chipset Configuration Setup BXT7059 / BXTS7059 Technical Reference
PEX10 PCIe port Bifurcation Control:
PICMG/PEX10 Port “Ax”: x4x4x4x4, x4x4x8, x8x4x4, x8x8, x16
Port A0 Link Speed: GEN1, GEN2, GEN3
Port A1 Link Speed: GEN1, GEN2, GEN3
Port A2 Link Speed: GEN1, GEN2, GEN3
Port A3 Link Speed: GEN1, GEN2, GEN3
PEX10 PCIe port Data Direct I/O Control:
PICMG/PEX10 Port A0: Disabled/Enabled
PICMG/PEX10 Port A1: Disabled/Enabled
PICMG/PEX10 Port A2: Disabled/Enabled
PICMG/PEX10 Port A3: Disabled/Enabled
Note: The number of link speed selections made visible will vary based on the
PCIe port selection; e.g. the x4x4x4x4 option will yield four PCIe link speed
selections. No speed selections are seen with the Auto option because the SHB
/ backplane combination will auto-negotiate link bifurcation and link speed.
QPI Configuration
This option allows the user to view, select or set to auto the link frequency of
the Intel® Quick Path Interconnect or Intel QPI between the dual processors on
a BXT7059 board. The two status messages listed at the top of this menu
indicate the current stat of the QPI interface as a function of the installed
processors and previous QPI link settings. Here is an example of two status
messages:
Current QPI Link Speed – Fast
Current QPI Link Frequency – 8.0GT/s
Trenton recommends using the QPI link defaults.
