Are you using the red or the blue ports? Qflash only works with the blue ports here.

Blue ports? USb 3.0? i use red just fine here.

For POST Code 6A please Disable "Ratio Change in OS" under advanced CPU configuration, like where turbo mode is. it is right next to CPU PLL Overvoltage. Supposedly they are still working on this.

Well, the Blue Ports are powered by a 3rd party USB 3.0 controller while the Red Ports are USB 2.0 powered by the x79 chipset southbridge which is fundamentally a safer solution, just like if you try to install Windows via USB.
