Core™ i7 Non-
Extreme Edition Processors
These performance settings will result in a processor frequency of about 4 GHz and are
applicable with the Intel Core i7 non-Extreme Edition processors. This includes the
Intel Core i7-970, i7-960, i7-950, i7-940, i7-930, and i7-920 processors. An Intel
tower model E88216-001 fan heatsink was used for processor cooling with these
performance settings.
Performance Settings
1. Power up system and press the F2 key to go into BIOS setup mode
2. These instructions assume default BIOS settings are present and only changes
from those defaults are listed below. Optionally, the F9 key may be pressed to
load Setup Defaults. If other BIOS configuration changes have been previously
made (i.e., SATA Configuration), they will need to be reapplied after loading Setup
Defaults.
3. From the BIOS Performance menu where the disclaimer asks if you wish to
