Hello. I have a B75M-A motherboard from asis and I use it with an i5 3470 and 2x4gb of 1600-9-9-9-27 hyperx blu. The motherboard should have the option "AI overclock tuner manual", but it isn't in the list. See picture: http://m.imgur.com/RJbP7Cg . How can I fix this?

When I click on the word Auto it just goes to automatic settings and I can't adjust bclk. I want to change my bclk 4-5% and this motherboard should be able to do that. But I can't find the option.
