The firmware update is only necessary in some special cases (e.g. to benefit from a new functionality added
to the firmware or to fix a firmware related bug). Before updating the firmware be sure what you are doing and
have a look into the change log (versionInfo.txt and/or the manual to see if the update will fix your problem).
The firmware update takes approx. 30 seconds!
11.2.3 How to disable CPU sleep states a.k.a. C states ( < Windows 8)
Modern PC's, notebook's, etc. try to save energy by using a smart power management. For this several hardware
manufacturers specified the ACPI standard. The standard defines several power states. For example, if processor
load is not needed the processor changes to a power saving (sleep) state automatically and vice versa. Every state
change will stop the processor for microseconds. This time is enough to cause image error counts!
