DCA Prefetch Delay

A DCA Prefetcher is used with a TOE (TCP/IP Ofoad Engine) adapter to prefetch

data in order to shorten execution cycles and maximize data processing efciency.

Prefetching data too frequently can saturate the cache directory and delay neces-

sary cache access. 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].

X2 APIC (Advanced Programmable Interrupt Controller)

Based on Intel's Hyper-Threading architecture, each logical processor (thread) is

assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to En-

able, the APIC ID will be expanded (X2) from 8 bits to 16 bits to provide 512 APIDs

to each thread to enhance CPU performance. The options are Disable and Enable.

AES-NI

Select Enable to use the Intel Advanced Encryption Standard (AES) New Instruc-

tions (NI) to ensure data security. The options are Enable and Disable.

Intel Virtualization Technology

Select Enable to use Intel Virtualization Technology support for Direct I/O VT-d sup-

port by reporting the I/O device assignments to the VMM (Virtual Machine Monitor)

through the DMAR ACPI tables. This feature offers fully-protected I/O resource

sharing across Intel platforms, providing greater reliability, security and availability

in networking and data-sharing. The options are Enable and Disable

Select Energy Efcient to support power-saving mode. Select Custom to customize

system power settings. Select Max Performance to optimize system performance.

Select Disabled to disable power-saving settings. The options are Disable, Energy

Efcient, and Custom.

If the option is set to Energy Efcient or Custom, the following items will display:

Cong TDP (Conguring Thermal Design Power)

Select Enable to congure TDP power settings to enhance thermal management.

The options are Enable and Disable.

Cong TDP Level (Available when Cong TDP above is set to Enable)

Use this item to set TDP conguration level to enhance thermal management.

The options are Nominal, Level 1, and Level 2.
