I have switched to another mobo for now, so I can't easily go back and check to see if these suggestions work. I know that often one must set a variable to a certain state to enable another variable. However, you will still see the second variable, it will just be greyed out. In this case, EIST and turbo mode are simply not there, not merely there but greyed out. Also, I would have enabled every power thing, including C1E and all C states, and looked to see if EIST and turbo suddenly appeared, but no, they were missing in action. OTOH, I don't see how a defect could cause them to disappear, so I'm at a total loss. Without being able to check anything, there's no point in pursuing this until I go back to the P6T. So if anyone has a P6T non-deluxe, please see if you have EIST and tubo under the CPU ratio entry.
