My guess from that label is that the modules you have are rated for the lower 666 MT/s data rate (so "6400" is marketing lies), your laptop is trying to drive them at 800 MT/s, and they're failing. I wonder if they are close enough to success for the computer to try to use them (maybe they claim internally to be compliant?) but not close enough for it to work.
You don't get a boot screen or the opportunity to get into BIOS settings or anything, right?
Nothing. Black screen, usual keys do nothing, fan on high.
