Was it TSX?

  Intel Transactional Synchronization Extension. When it works, you get support for database-like transactions on RAM (only small transactions, it isn't black magic). When it fails, you get all kinds of random crashes at random times. Introduced in Haswell, turned out to be buggy and Intel famously disabled it with ucode update. Since then, they quietly disabled it also for several Broadwells and Skylakes which didn't fare much better than Haswell. edit: it seems I misread parent's post as "what is TSX"

    Me too did.. but I was about to google TSX before the last two posts. So thanks for the explanation.
