Re: Z77 Extreme4 AXTU issue
You could download passmark 64 bit, then compare your CPU score to a base line CPU score, your's should be higher.
BTW, I would set your multiplier in the BIOS and just use the tuner software as a hardware monitor, you'll thank yourself for doing this in the long run.
Other than that, what you are experiencing is normal, it idles the CPU down to 16x when not needing any extra horse power. It'll throttle up right away. You can have ATXU open and run the passmark test and see what I mean.
