This setting indicates the minimum assertion width of the SLP_S4# signal to ensure that the
DRAMs have been safely power-cycled. Setting values are: [4 to 5 seconds], [3 to 4 seconds],
[2 to 3 seconds], [1 to 2 seconds].
► ASPM
Active State Power Management (ASPM) allows power to be incrementally reduced to indi-
vidual serial links in a PCI Express fabric as a link becomes less active. ASPM is dened in
the PCI Express base specication. Enables or disables ASPM for a Link, based on the overall
system power policy, the hardware capabilities of the Link, and the latency of the Link. Hard-
ware performs the actual power management operations of transitioning Links between Link
power states and resynchronizing Links. The conguration of the PCI Express implementation
on a system affects the amount of power savings that can actually be achieved.
