Intel Desktop Board DZ77GA-70K Tuning

using Over-Clocking Assistant™

Included in the DZ77GA-70K Visual BIOS™ setup program is an automated method to
over clock using pre-tested built in settings. These settings have been extensively
developed and tested in Intel’s over clocking laboratory and will work with most
system configurations.

The Overclocking Assistant can be found on the home screen of the Visual BIOS setup.
Note the ‘Unlocked’ icon which shows that an Intel K-SKU processor is installed and
over clocking is unlocked and available. Non Intel K-SKU processors are locked and
can not be overclocked.
