Memory Rank Sparing

Select Enable to enable memory-sparing support for memory ranks to improve

memory performance. The options are Disabled and Enabled.

Patrol Scrub

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 IO hub 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 IO hub

will be scrubbed every day. The options are Enable and Disable.

Patrol Scrub Interval

This feature allows you to decide how many hours the system should wait be-

fore the next complete patrol scrub is performed. Use the keyboard to enter a

value from 0-24.

Demand Scrub

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 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 Enable to use Demand Scrubbing

for ECC memory correction. The options are Enable and Disable.

Device Tagging

Select Enable to support device tagging. The options are Disable and Enable.
