I have this board, and was intrigued by the Turbo Boost problem. Can you explain it in further detail, and how you solved it?
And I have a problem regarding the fan velocity regulation in my setup - using the Asus AI Suite, even setting the fan to only spin up when it reaches some temperature (using the custom fan speed graphics), it almost always spins up the CPU fan to the maximum when the CPU clock is turned to the maximum, even when the CPU temp is way lower than the AI Suite setting. Read somewhere that it is a AI Suite problem - if you uninstall the application and adjust the fan curve only in BIOS, it works properly, but I wonder if you saw something similiar in your test.
Thanks for the review.
