ASRock Z77 core ratio settings missing?

[Pibben2]

I was planning to buy a ASRock Z77 Extreme4-M motherboard. However, when I read the manual I didn't find any setting for 1/2/3/4 core ratio limits. This settings seems to be available in other brand's boards.

Could anyone confirm that this setting actually is missing, or if its just an omission in the manual.
