Chapter 4: AMI BIOS

Demand Scrubbing

This is a memory error-correction scheme which will allow the processor to write correct data back into the memory block from where it was read by the processor. The options are Enabled and Disabled.

Patrol Scrubbing

This is a memory error-correction scheme working in the background looking for and correcting resident errors. The options are Enabled and Disabled.

Throttling - Closed Loop

Throttling improves CPU's reliability and power efficiency via automatic voltage control during idle states. The options are Enabled and Disabled.

North Bridge Configuration

This feature allows the user to configure the settings for the North Bridge chip.

Intel I/OAT

The Intel I/OAT (I/O Acceleration Technology) significantly reduces CPU overhead by leveraging CPU architectural improvements, freeing up resources for other tasks. The options are Disabled and Enabled.

DCA Technology (Available when Intel I/OAT is enabled)

Select Enabled to use Intel's DCA (Direct Cache Access) Technology to enhance data transfer efficiency. The options are Enabled and Disabled.

DCA Prefetch Delay

A DCA Prefetch is used with TOE components to prefetch data to shorten execution cycles and maximize data processing efficiency. Prefetching too frequently can satu- rate the cache directory and delay necessary cache access. 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], [120].

IOH PCI-e Max. Payload Size

Some add-on cards perform faster when the payload size is limited to 128 Bytes; while others, with a payload size of 256 Bytes. Please refer to your add-on card user guide for the desired setting. The options are 256 Bytes and 128 Bytes.

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,
