A few days ago I installed the new crimson drivers and noticed a few problems. First, cant reset settings and get some strange numbers in memory clock speed. Second is a problem with Fan speed also dont save settings and after start up windows must go and change fan speed. Third is a temp. in older drivers I have in idle 40degress now is 46, I could play in 60-70degrees now I have problem with 56degrees because the image begins to show squares and stripes. Doesn't help installing Crimson 15.11.1. Hope AMD will fix that soon.
