Could someone kindly tell me if this board has locking mechanism for sata frequency? I am now trying to overclock my 3700+ but I can't find any settings inside bios that seem to do the job? Only setting I can find there is frequency adjustment for pcie, does this mean if I lock this value to 100, all my sata drives frequency will be locked accordingly(so that they won't be affected by overclocking)? Thanks for your help in advance. Cheers.
