Operating system Windows 7 64 bit sp1. My motherboard MSI Z97-gaming 5 (3x16 and 4x1pin PCI slots).
My probelem is when I installed 4 graphicscards all of them showing up and working . But when installing others, system rejecting them with (eror code 43)all of them fully functional. I updated to latest driver version, uninstalled and reinstalled one by one, but still same problem. When i solving one other one having problem. When i solving 3 other 3 having problem. Anyone knows how to fix this eror?

I checked all adapters one by one( powering off, disconnecting 6 risers from motherboard, then turning on, checking adapter with gpu) all of them working. But when I connecting all adapters to motherboard 3 of 7 cards giving eror 43. Driver updated to last version. I am not sure, maybe problem with BIOS? Or WINDOWS version?
