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 fullyprotected 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
