RX 480 CrossFireX issues (all games)

Hi all.

 

I recently bought two Sapphire Nitro+ RX 480 cards to run in CrossFireX but this system doesn't work in any of my PC games (e.g. The Witcher 3 GOTY edition, Dark Souls 3 and so on).

Each time I run them I "always" get 20-30 Fps but both cards run fine and load 90-100% (GPU1 and GPU2); the CPU load is from 80 to 92.

 

On the other hand, when I run Heaven Benchmark all it works fine (I get 85 Fps on average, CPU load from 90 to 95 and a score of around 2200).

 

 

What's wrong with my system? Do you have any suggestions? Thanks a lot anyway!

 

 

My system information are:

 

CPU: Intel Core 2 Quad Q9650 @ 3,00 GHz

RAM: 8 GB DDR3 1600 MHz Corsair Dominator

MB:   Asus P5E3 Pro (with 2 PCI-E 2.0 slots both @ 16X)

GPU: Sapphire Nitro+ RX 480 x 2

HD:   SSD Samsung 850 EVO

AMD driver: Crimson ReLive Edition 17.2.1

OS:   Windows 10 64-bit
