I upgraded my 1600 to the 2700X after flasing bios to the lastest non-beta.
I'm now getting processes just terminate in Ubuntu 16.04 LTS - this wasn't happening with my 1600
I've tried turning of cstate like the 1700x's but nothing seems to help. I get the occasional full lockup too.
Really annoying to pay this much, only to be outshined by the quiet and cheap achiever.
