Sleeping became difficult as any pressure would cause the ear to throb. However, after a restart and then going into the BIOS again, the full 3200Mhz showed for all 4 sticks :)So, as other reviewers have said, set your XMP to Profile 1. I get a lot of compliments on them though. How about a "low battery" signal??? Subtracting one star. A lot of feedback noise. Hope this helps good luck The pads were easily installed and are reported to be just as comfortable as the original pads. These guys fill that gap and provide a quality product And better than the original cord because the mute button actually works! Im not used to having slippers with backs on them, but you can stand on the back of them if you want to because they will fold down.
