Channel Mirror - The motherboard maintains two identical copies of all data in
memory for redundancy.
Lockstep - The motherboard uses two areas of memory to run the same set of
operations in parallel.
Sparing - A preset threshold of correctable errors is used to trigger fail-over. The
spare memory is put online and used as active memory in place of the failed
memory.
Demand Scrubbing
Demand Scrubbing is a process that allows the North Bridge to correct correctable
memory errors found on a memory module. When the CPU or I/O issues a demand-
read command, 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 cor-
rection. The options are Enabled and
Disabled.
Patrol Scrubbing
Patrol Scrubbing is a process that allows the North Bridge to correct correctable
memory errors detected on a memory module and send the correction to the re-
questor (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 - Open Loop
If set to Enabled, Throttling - Open Loop will be activated when the projected
memory temperature exceeds a predefined trip-point. This process can effectively
improve memory thermal performance. The options are
Disabled and Enabled.
Inlet Temperature
This is the temperature detected at the chassis inlet. Each step is in 0.5
o C
increment. The default is [070]. Press "+" or "-" on your keyboard to change
this value.
Temperature Rise
This item allows the user to define the temperature rise parameter of a memory
module to be used to improve memory power management. Each setting is in
0.5
o C increments. The default setting is [020]. Press "+" or "-" on your keyboard
to change this value.
