Can someone to into a bit more detail on what they've done to get 8 or 9 GPUs working on this board using the M.2 slots and adapters?  I've been able to get 7 GPUs working fine, but can't seem to get an 8th to be recognized when using the M.2 slot/adapter.  I know Win10 has the 8 GPU limit, and was hoping to squeeze in one more card.

Have the latest bios with 'Above 4G' enabled and slots set to Gen 1.  Latest Nvidia drivers and all the latest W10 patches.
