Good question. I've researched a bit on the web and cannot find an answer either but I have a feeling it is with saving profiles. Nate, XTU is an overclocking utility by Intel, it was standard on my old Intel Extreme DP67BG board, back then you had to have an extreme board to use it. It makes changes from within OS for overclocking plus has stress tests and benchmarking. I don't believe it is LLC because then there would be two settings in the BIOS for vdroop but you never know until more info becomes of it.
