No PCIe Port Active ECO
This item provides a workaround solution when there is no PCIe port active.
The options are PCU Squelch exit ignore option and Reset the SQ FLOP by
CSR option.
Socket 0 PCIED00F0 - Port 0/DMI
This submenu allows the user to confi gure the settings for the following PCI-E
ports: 0, 1A, 1B, 2A, 2B, 2C, 2D, 3A, 3B, 3C, and 3D.
Link Speed
Use this item to confi gure the link speed of a PCI-E device installed on the
PCI-E slot specifi ed by the user. The options are Auto, Gen 1 (2.5 GT/s), and
Gen 2 (5 GT/s).
PCI-E Port DeEmphasis
DeEmphasis is used to decrease the magnitude of very high frequencies in
relation to the magnitude of very low frequencies to improve the overall signal-
to-noise ratio by reducing the level of all (signals) data bits transmitted except the
fi rst one, acting as a form of transmitter equalization to enhance signal transmis-
sion and audio performance. The options are -6.0 dB and -3.5 dB.
The following items will display:
PCI-E Port Link Status
PCI-E Port Link Max
PCI-E Port Link Speed
PCI-E Port L0s Exit Latency
Use this item to confi gure the exit latency of the PCI-E port L0s link state, mea-
suring the length of time needed to transition from the L0s link state to L0. The
available latency option is 4uS - 8uS. (Note: "uS" stands for "microseconds.")
PCI-E Port L1 Exit Latency
Use this item to confi gure the exit latency of the PCI-E port L1 link state, measur-
ing the length of time needed to transition from the L1 link state to L0. The latency
options are <1uS, 1uS - 2uS, 2uS - 4uS, 4uS - 8uS, 8uS - 16uS, 16uS - 32uS,
32uS - 64uS, and >64uS. (Note: "uS" stands for "microseconds.")
Fatal Err Over (Fatal Error Overwrite)
This item confi gures the option to overwrite fatal errors. The options are Dis-
able and Enable.
