CPU2 SLOT7 PCI-E 3.0 x8
Use this feature to set the PCI-E bus speed for the slot specied above. The
options are Gen (Generation) 1 (2.5 GT/s), Gen (Generation) 2 (5 GT/s), and
Gen (Generation) 3 (8 GT/s).
IOAT Conguration
Enable IOAT (I/O Acceleration Technology)
Select Enable to enable Intel I/OAT (I/O Acceleration Technology), which signi-
cantly reduces CPU overhead by leveraging CPU architectural improvements
and freeing the system resource for other tasks. The options are Disable and
Enable.
No Snoop
Select Enable to support no-snoop mode for each CB device. The options are
Disable and Enable.
Relaxed Ordering
Select Enable for relaxed ordering support, which will allow certain transactions
to be processed and completed prior to other transactions that have already
been queued and that violate the strict ordering rules of PCI processing. The
options are Disable and Enable.

VT for Directed I/O (VT-d)
Select Enable to enable Intel Virtualization Technology to support Direct I/O VT-d
Technology by reporting the I/O device assignments to the VMM (Virtual Machine
Monitor) through the DMAR ACPI tables. This feature offers fully protected I/O
resource-sharing across Intel platforms, providing greater reliability, security, and
availability in networking and data-sharing. The options are Enable and Disable.
