I bought a new POWERCOLOR R9 380 4G(AXR9 380 4GBD5-PPDHEV2) in the shop last week.
After i installed Crimson ReLive 17.4.3, my video card was identified as "R9 200 Series".
17.4.4 was the same problem.
The only way to show up R9 380 is using Windows 10 update driver.
However, this version was easily made system halt.
