QuickPath Interconnect (QPI) offers three power states called L0, L0s and L1:
• L0 is a normal operational state where data and control packets can be transmitted
and received. All power management states are entered from this state.
• L0s is intended as a power saving state. It allows a link to quickly enter and
recover from a power saving state without going through recovery.
• L1 is a power saving state that allows an additional power saving over L0s, but
with additional resume (wake-up) latency.
Select Enabled to activate QPI power saving (L0s and L1 are automatically selected
by the motherboard), select Disabled for normal operational state without any
power-saving function. The options are Disabled and
Enabled .
3.2.3.5 Memory Frequency
This feature forces the system memory to run at a different frequency than the
default frequency.
The available options are Auto , Force DDR-800, Force DDR-
1066, and Forc e DDR-1333 .
3.2.3.6 Memory Mod e
The options are Independent , Channel Mirror, Lockstep, and Sparing .
Independent —All DIMMs are available to the operating system .
Channel Mirror —The motherboard maintains two identical copies of all data i n
memory for redundancy.
Lockstep —The motherboard uses two areas of memory to run the same set of opera-
tions in parallel .
Sparing — Memory sparing occurs when on-demand inactive memory is automati-
cally activated by the system to temporarily replace failed memory until a service
action can be performed (supported only on 2010 Intel® Core™ processor family
based on the 32nm Intel® micro architecture).
3.2.3.7 Demand Scrubbing
Demand Scrubbing is a process that allows the CPU to correct correctable memory
errors found on a memory module. When the CPU or I/O issues a demand-read com-
mand, and the read data from memory turns out to be a correctable error, the error is
corrected and sent to the requestor (the original source). Memory is updated as well.
Select Enabled to use Demand Scrubbing for ECC memory correction. The options
are Enabled and
Disabled .
