Hello There,
I've recently bought a new ASRock B450 STEEL LEGEND Motherboard, it comes with six PCIE slots, I want to use 4 graphics card with this motherboard. But it give no display whenever I put more than two graphics cards. These two too only works in PCIE1 and PCIE2 slots, other slots are not working even with single graphics card.
My specs are:
CPU: AMD Athlon??3000G Processor with Radeon??Graphics
RAM: XPG ADATA GAMMIX D30 DDR4 8GB 3200MHz
OS: Windows 10 64 Bit - Fully updated
Everything works really well when using only two graphics card in first two slots. I've installed chipset and other relevant drivers, updated everything in windows.

I've Ndivia 3060 Ti (x2), AMD 570 & AMD 590. Any two works well in first two slots, no one works in any later 4 slots.
