Perfmon and DFX Devices
A PerfMon device monitors the activities of a remote system such as disk us-
age, memory consumption, and CPU load which will allow an IT administrator to
maximize the performance of each computer within the network. A DFX device,
usually in the form of a USB adaptor, can be used to enhance audio performance.
Select Unhide to display the Perfmon and DXF devices installed in the system.
The options are HIDE and UNHIDE.

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 Enabled and Disabled.
