I take it you are not getting a BSOD such that you can identify the error code? I do not use offset mode and am not familiar with Asus bios so someone else may be of more help to you. I would say that 1.184v for the CPU voltage does look low to me even with LLC on ultra high. (I think my 2600K was 1.26v @ stock and have read somewhere that stock voltage is between 1.24 - 1.26v) That said you may just have a particularly good chip that has a very low stock voltage.
