So what´s the deal when using Ubuntu´s memtest the One just reboots randomly but doesn´t show any mistakes in memory?? Memtest version 1.70 not good for the One? The reason why i´m posting it over here at the hardware is that i don´t believe it´s because of the software version of that memtest. Anyone having same issues? I started to check the memory because of a sudden reboots.. i guess i´m now entering the problem zone after all....
