Thanks for joining the processor community.
I understand you are trying to enable turbo boost of Intel i7-4700MQ processor.
The processor supports that feature. This information is available here: http://ark.intel.com/products/75117/Intel-Core-i7-4700MQ-Processor-6M-Cache-up-to-3_40-GHz?q=Intel%C2%AE%20Core%E2%84%A2%20i7-4700MQ%20Processor%20(6M%20Cache,%20up%20to%203.40%20GHz)
Normally, computer manufacturers enabled this feature by default and the only way to access turbo boost would be through BIOS settings. You need either check with your computer manufacturer for information about support for turbo boost on new BIOS updates or through your BIOS setup screen.
I regret to inform you that Intel does not offer the software to download turbo boost anymore on intel.com, this has been removed since June 30th, 2014.
See here for more information about it: http://www.intel.com/support/processors/sb/cs-031089.htm
Please check with your computer manufacturer for possible software downloads.
