[Feferiko]

Hi All;

I created my rig yesterday with Asus Z270-P and 5 Sapphire Rx 580 8gb Special Edition.

I try so many thing but, only 4 cards are visible, cant see the 5th card. I change the Pci slots, cards are working but i cant see any of them in Windows 10 Pro.

I see some ppl can use 7-8 cards with this board and cards. I enabled the 4g on board. Riser versions 9...


Please help me mates...

1. remove all cards, except one
2. go to bios - turn off all unused ports(usb,serial,sata), contollers ( sata), sound card, utrn on all PCE-E settings gen1 or Gen2, tur on 4G decoding
3. save reset. load windows. shut down
4. plug all cards, load windows, install drivers - you are good to go

Don't remove the cards..
Download latest drivers and DDU
Reboot into safe mode (hold left shift while selecting reboot)
Run DDU, tell it to full uninstall
Disconnect Internet Cable and reboot into normal mode
Now you should see all 5 cards under device manager as Microsoft Standard Display
Run the latest driver install
If drivers ask to reboot let it reboot
Confirm all 5 display cards are there
Plug Internet cable back in.

I’ve given up on the 6 that I bought, for me it’s not worth the effort to get the motherboard to run so I’m trying the z370a pro

Start with DDU and double check your connections.
Might want to check the card as a stand alone with that riser to make sure it works too.

Run linux, problem solved.

Please stop spamming with useless posts.

Why are you giving up?  I have two six card rigs running with Z270 boards.  I did have problems on the first one, but after changing the bios settings, no problems whatsoever.
