Throttling - Closed Loop/Throttling - Open Loop
Throttling improves reliability and reduces power in the processor by automatic
voltage control during processor idle states. Available options are Disabled and
Enabled .

North Bridge Confi guration
This feature allows the user to confi gure Intel IOH settings.
NB Revision
This item indicates the revision number of the Northbridge chipset.
Intel I/OAT
The Intel I/OAT (I/O Acceleration Technology) signifi cantly reduces CPU overhead
by leveraging CPU architectural improvements, freeing resources for more other
tasks. The options are Disabled and Enabled .
DCA (Direct Cache Access) Technology
This feature works in conjunction with the Intel I/O AT (Acceleration Technology) to
accelerate the performance of the TOE device. When this feature set to Enabled, it
will enhance overall system performance by providing direct cache access for data
transferring. The options are Enabled and Disabled.
DCA Prefetch Delay
A DCA Prefetcher is used with TOE components to prefetch data in order to
shorten execution cycles and maximize data processing effi ciency. Prefetching too
frequently can saturate the cache directory and delay necessary cache accesses.
This feature reduces or increases the frequency the system prefetches data. The
options are [8], [16], [24], [32] , [40], [48], [56], [64], [72], [80], [88], [96], [104], [112],
and [120].
Intel VT-d
Select Enabled to enable Intel Virtualization Technology support for Direct I/O VT-d
by reporting the I/O device assignments to VMM through the DMAR ACPI Tables.
This feature offers fully-protected I/O resource-sharing across the Intel platforms,
providing the user with greater reliability, security and availability in networking and
data-sharing. The options are Enabled and Disabled.
Active State Power-Management
Select Enabled to use the power management for signal transactions between the
PCI Express L0 and L1 Links. Select Enabled to confi gure PCI-Exp. L0 and L1 Link
power states. The options are Disabled and Enabled.
