I have same asus motherboard with 11 card using 2 m.2 to pcie and and pcie 4x splitter.

I have test same spliter and m2 adapters on msi gaming m7 without flaws

Last official firmware and Windows 10 on both.


 

MSI Z170A Gaming M7 ?!

One of the 2 m.2 adapters won't work on this board actually. There is a point in the manual which says something about the m.2 slot in combination with PCIe slot.
Furthermore the latest bios also doesnt work for me. I have to use an old one.
Please explain what exactly you did.

Best regards,



Mr.ARgful

Nothing special, manual indicates that one pcie slot is lost if you use two m2 ports but I have tested (lastest bios) and it´s false for my board.... Grin

I have tried with M.2 pcie Adapter+SSD M.2 and a gpu on indicated manual lost slot and works.



Do i get it correctly:

You tried two normal M.2 -> Pcie Adapters? What kind of adaters did you use? Pls provide a link of the adapter YOU USE, because its also about the pcie speed.
Furthermore, which PCI risers are you using? Which PCIe Spped are they?
Please see this spot in the manual, which says that :
Important
●● The M2_1 slot will only run PCIe 3.0 x2 speed when
M2_1 slot is installed with a M.2 PCIe device and
PCI_E4 slot is installed with a PCIe x1 device at the
same time.
●● Intel® RST only supports PCIe M.2 SSD with UEFI
ROM, does not support Legacy ROM.

So this might be the problem?!?!

Best regards

I make test again and works, 8 cards+SSD M2 working, I am using M.2 adapter with floppy power conector not new usb model, risers are molex model rev 003, 003s and 006, riser connected to M.2 adapter is 003.

I cant test 2 M.2 adapters because need SSD M2 to boot but this configuration should not work according to the manual


Thank you very much for you effort.
But your last sentence confirms, it is not possible to run 9 GPU (7 in pCIe Slots + 2 in M.2 Slots) and thats what i wanted to say in the beginning.
Im just able to run 1 extra GPU in M.2. To get more than 8 GPUs running, you probably need a PCIe Splitter 1 -> 3 Adapter.
