ATTEMPTED EXECUTE OF NOEXECUTE MEMORY - Appears when 6th GPU is connected

[Crypto_Future]

Ok here is the deal.

Got 2 rigs g4560, Asus Prime, 8gb ram & x6 470 8gb


Both rigs work with all Six gpu with smOS.


Windows 10 enterprise boots only when 5 GPU are connected, as soon as I connect a 6th they Crash on Boot with ATTEMPTED EXECUTE OF NOEXECUTE MEMORY


Whichever gpu I disconnect and leave 5 online, windows boots all 5 cards recognized....


Does anyone know about this issue;

Do windows 7 support 6 GPU + igpu, do I need a mod for that ?
