Well we all know this BIOS is a work in progress and for whatever reasons my BIOS is still buggy. I'm going on my 2nd month of problems trying to get the BIOS to work right. For the last week I have been trying to get this MB to over clock with auto voltage while maintaining the power efficiency features and increasing the Turbo Boost limits. With the new MB and new fresh official BIOS my MB still doesn't allow for this feature to work. I even took my 2500k back to the store to exchange because I thought it may be the CPU. Great thread to read about setting this configuration up. http://forums.overclockers.co.uk/showthread.php?t=18340310 Any help on this subject is appreciated.
