You say the Asus Z270-A Prime can do 9 GPU's, however all the forum posts I've seen says 8 is the limit. Such as: https://steemit.com/crypto/@cryptos/8x-rx-580-gpu-crypto-mining-rig-with-asus-prime-z270-a-motherboard

Do you or anyone here can point me to a thread or post with someone who has got 9 GPU rig running with success?
