i have a issue with my 4GB Sapphire Radeon R9 270X card

I bought a new mainboard yesterday H97 D3H gigabyte


After I installed the graphics card to the new mainboard ...  I only saw blackscreen ..

I found this post on the internet what is may be exactly my issue


R9 series GPU & Gigabyte Motherboard possible incompatibility - [Solved] - Graphics Cards


I have done the following:

,,motherboard's BIOS and in PCIe slots settings I turned from EFI to Legacy support"


I only have found the setting ,,Other PCIe devices .... turned from EFI to legacy


My graphics card was then recognized, I could play for 10 minutes ... Then again .. Blackscreen ..

Does somebody has any idea ? Because the graphics card worked without problems before exchange ..
