NorthBridge configuration
This feature allows you to configure the settings for the Intel
NorthBridge chip.
Figure 3-145. NorthBridge configuration
Intel I/OAT: Significantly reduces CPU overhead by leveraging CPU
architectural improvements, freeing resources for other tasks.
DCA Technology: Uses Intel's DCA (Direct Cache Access) Technology to
enhance data transfer efficiency.
DCA Prefetch Delay: 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.
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
you with greater reliability, security and availability in networking and
data-sharing.
