NorthBridge Chipset Configuration
Intel I/OAT: Significantly reduces CPU overhead by leveraging CPU
architectural improvements, freeing resources for other tasks.
DCA Technology: Select Enabled to use Intel's DCA (Direct Cache
Access) Technology to improve data transfer effi ciency.
DCA Prefetch Delay: A DCA Prefetch is used with TOE components to
prefetch data in order to shorten execution cycles and maximize data
processing effi ciency. A TOE device is a specialized, dedicated
processor that is installed on an add-on card or a network card to
handle some or all packet processing of this add-on card. 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], [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
you with greater reliability, security and availability in networking and
data-sharing.
Active State Power-Management: Uses power management for signal
transactions between the PCI Express L0 and L1 Links. Select Enabled to
configure PCI Express L0 and L1 Link power states.
IOH PCIE Max Payload Size: Some add-on cards perform faster with the
coalesce feature, which limits the payload size to 128 MB. Others
