The reason why you are not able to see this is because the Intel® Core™ i7-970 Processor cannot be overclocked, therefore the options under "Advanced Tunning" are not available.
The board is not able to OC either as per chipset P55 features.
I do not own the i7-970. I own the i7-870.
My motherboard has extensive OC capabilities, both from BIOS (including dynamic vcore) or from the ASRock OC Tuner (Voltage, multiplier, hw monitoring etc...).
At the VERY least it should be possible to toggle Turbo Boost.
Thanks for the reply.
The Intel® Core™ i7-870 Processor cannot be overclocked, only processors that have an "x" or "k" in its code name are unlocked which means they can be overclocked.
Regarding Intel® Turbo Boost Technology, it is typically enabled by default. You can only disable and enable the technology through a switch in the BIOS. No other user controllable settings are available. Once enabled, Intel® Turbo Boost Technology works automatically under operating system control.
