Since it was suggested that it is most likely an hardware or diver issue I went ahead and retested with 349. According to the changelog the only major difference to 351 should be Satori.
Tried over 10 times (deleting the package-cache between tries and rebooting windows once) but no bluescreen.
But maybe 349 has just more luck?
The machine I am testing on had 128 GB of RAM installed (4 * 32 GB). XMP disabled. Tried with only 32GB (with different Ram sticks in different slots). Did not make a difference.
