RMC 7182
1U Rackmount System
QPI L0s and L1
Select Enabled to lower the QPI power state. L0s and L1 are automatically selected by the
motherboard. The options are Disabled and Enabled.
Memory Frequency
Use this option to force the system memory to run at a different frequency than the default fre-
quency. The available options are Auto, Force DDR-800, Force DDR-1066, and Force DDR-1333.
Memory Mode
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 in memory for redun-
dancy.
Lockstep - The motherboard uses two areas of memory to run the same set of operations in paral-
lel.
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 re-
questor (the original source). Memory is updated as well. Select Enabled to use Demand Scrub-
bing for ECC memory cor- rection. 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 perfor-
mance. The options are Disabled and Enabled.
Inlet Temperature
This is the temperature detected at the chassis inlet. Each step is in 0.5oC 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
0.5oC increments. The default setting is [020]. Press "+" or "-" on your keyboard to change this
value.
