SUPER MICRO Computer X8ST3-F 4-10, Demand Scrubbing, Patrol Scrubbing, Throttling - Open Loop

X8ST3-F/X8STE User’s Manual

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 0.5oC 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.
