Multi Card issue with ASrock H110 Pro BTC+

[Pujols89]

Got a bit of a head scratcher with my ASRock h110 Pro BTC+.

I have a total of 5 x rx 480's, and 1 x rx 580. No matter what I do I can only have 4 in there without running into "Code 43" on my windows 7 powered machine.

I have applied the pixel patcher from AMD, so it's not a modded BIOS problem.
I have rotated the cards with just about every possible way, eliminating any faulty risers, or faulty cards
I have tried at least 3 different AMD drivers, 17.9.1 and 17.9.3 as well as the blockchain driver, all to no avail

I'm running out of ideas at this point. Anyone have any suggestions beyond a fresh install of windows? (which I will revert to this weekend as a last case scenario)

Found this, have you tried it?

Windows 7 only supports up to 4 cards of the same type (AMD or Nvidia). There is a driver hack that you can try, but it hasen't been updated in over a year.

The latest version of Windows 10 Fall Creatotrs Update supports 13+ AMD cards.  You can also update to Windows 10 for free using the Assistive technologies upgrade page.

which version of windows you use???
my suggestion is windows 10 with amd compute drivers...
also plug 4pin power connector to motherboad if you get "error 43",
if it does not work text me i can help you on team viewer.
i m also running h110 btc pro+ for 13 gpu...!!!

hey guys sorry for the late reply, as per the OP I am using Windows 7. I don't believe your point about only Win10 supporting 4+ cards is correct.... I have read things like this:

Does anyone else have any suggestions? Does anyone know the latest version of Crimson drivers that work with AfterBurner 4.4? I am sick of Sapphire Trixx, it is a very annoying program.

Thanks,
Greg

That it is not even true.
I can run 6x gtx 1070 without any problem under win7 64bit.
You can run almost unlimited number of gpus under 64bit system. The only problems are drivers and motherboards.
Not windows.

The fix is to run linux. Windows is dogshit for mining.
