I have updated using the latest ASUS bios and the TSX instruction which Intel stated, needs to be disable by a manufacture BIOS update is still enabled. Latest ASUS BIOS is using microcode ending in 19 dated 2/26/14. There has been two microcode updates for the Haswell CPU since 19. According to what i have read this instruction can cause erratic system behavior.
I don't relay want to use a third party app to do this myself. If I could get a response from Raja@ASUS or MarshallR@ASUS I would greatly appreciate it. I posted a screen shot showing both bios version 2012 & 2304 showing both have the same microcode id 036c319 & Cpu-z showing the instruction as enabled.
"Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free" R.R.
