X8SAX/C7X58
Patrol Scrubbing
Patrol Scrubbing is a process that allows the CPU to correct correctable
memory errors detected on a memory module and send the correction to the
requestor (the original source). When this item is set to Enabled, the North
Bridge will read and write back one cache line every 16K cycles, if there is
no delay caused by internal processing. By using this method, roughly 64 GB
of memory behind the North Bridge will be scrubbed every day. The options
are Enabled and Disabled.
Throttling - Closed Loop
Throttling improves reliability and reduces power in the processor by au-
tomatic voltage control during processor idle states. Available options are
Disabled and Enabled.
Performance Tuning Mode (Available on the C7X58 only, when both XMP
memory and an Extreme Edition CPU are installed.)
This item allows the user to choose the Intel Extreme Memory Profile (XMP) Speci-
fication which enables DDR3 memory to operate beyond the standard JEDEC SPD
specification. Select XMP for 1600 MHz XMP memory operation and better system
performance. Otherwise, leave this setting on Auto.
HDA Controller
Select Enabled to enable the High-Definition Audio controller. The options are
Enabled and Disabled.
Intel VT-d
Select Enabled to enable Intel's 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 the user with greater reliability, security and availability in networking and
data-sharing. The settings are Enabled and Disabled.
SR-IOV Support
Enable this item to support Single Root I/O Virtualization and Sharing (SR-IOV).
The options are Disabled and Enbaled.
Intel I/OAT
The Intel I/OAT (I/O Acceleration Technology) significantly reduces CPU overhead
by leveraging CPU architectural improvements, freeing resources for more other
tasks. The options are Disabled and Enabled.
