Installing 7 graphics cards to windows 7

[Martmart1]

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?

You are attempting to connect graphic cards to the PCIe x1 slots ? Using some type adapter ? A PCIe x1 slot can't supply as much power as a PCIe x16 slot. Do your adapter(s) have supplemental power ?

All GPUs connected via PCIe x16 to x1 adapter riser and all of them connected to supplemental power from PSU. I am using 2 PSU.

Can you get the x1 card to work with no other cards?

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?

NVIDIA or AMD cards?

Those cards compatible with my OS Windows 7 64 bit SP1 Ultimate. And my motherboard too.

I found this article on six GPUs -- http://www.gobitgo.com/articles/1002/How-to-Mine-with-6-GPU/ and it sounds like a 43 status is not uncommon. They specifically used Windows 8 (I don't know why).

Good Luck.

That's what I wanted, thanks😉
