As per my specs attached, I am using ASROCK FATAL1TY 990FX PROFESSIONAL motherboard where I have issues with Crossfire setup.
The 2nd PCIe slot doesnt work (named as PCIe_4) which is just below the master slow.
I tried individual cards on this 2nd PCIe slot but still it doesnt work, I am running latest BIOS & the 2nd card is not detected.
However, the most below PCIe slot works with Crossfire but the 3rd PCIe slot is running at 4x speed & on this setup, the system freezes after 1 min of runtime of games.
I am doubting that the 2nd PCIe slot is faulty?
ASROCK & Forum members pls help, how to run CF setup successfully? I do not find any CF options in UEFI bios menu too.
