OK. Got my X1 today (saturday!).
Pluged it in, set pool and it's up and running with with 125 Gh/s 100°C.
Freq changes from 1200 to 1100 and back ... Don't know how to change that to fix freq yet.
I can only run it at 1100Hz and runs at around 110GH/s on average. (its been running at 60C ALL the time). I dunno if this is accurate as the graph is 60C ALL the time even at night and day when the ambient temperate is different by quite a bit)
If I change to 1200Hz then it just fails completely when it tries to start up mining.
