Same card different name. There is no error.
Same problem here.please tell solution.
There is no solution because there is no problem, it's just how AMD decided to name GPUs in the drivers.
Please take a look at the information provided by Wikipedia.org from the link below
I found there exist slightly differences between them both. You can use Download TechPowerUp GPU-Z v1.12.0 | techPowerUp to obtain the further information about your GPU. CPU-Z, AIDA64, HWINFO32/64 and so forth also provides related information, you can also use them to make a comparison. The Crimson driver might treat those similar GPUs in the m440 series rather than differentiate them in detail.
