Hey guys can any one help me with MSI Z270 Pro A Bios settings?
I was able to install manually 6 GPU RX 570 using the technique described in earlier posts.
https://www.newegg.com/Product/Product.aspx?Item=N82E16813130993However when I boot up it only recognizes both cards in pcix16 slots and doesn't recognize pci x1 cards
When I enable an option in BIOS for Enable 4G Encoding Yes and PEG to Gen1
Windows gives me blank screen.
Without it boots up an i can see all 6 cards but only 2 are working with Drivers. I saw a posts by a member regarding MSI Z270 6 GPU working however I cannot find the same posts again [believe me I have searched]
they had a link for newegg link thats what i used to purchase however I cannot get the damn thing working with 6 gpu.
Thank you,

Alright first off, for Z170 and Z270 chipsets, I found that the best way to get the 5th card working is to DISABLE memory encoding, install one graphics card at a time. If you're getting any code 43's on 4 cards, you need to regedit hack Windows "DisplayLessPolicy" and "LimitVideoPresentSources" (google). Once 4 work fine, install the 5th and reboot. Now you should be getting code 12's. NOW you go into BIOS and Enable 4G Encoding. Start Windows. 4 cards may work but one card might report problems. Disable this card in windows, wait 30 seconds, reenable it. It works. If you have older drivers, you're on your way to 6+ GPUs.
On top of that, make sure you do UEFI only booting, not Legacy+UEFI, and confirm that works with 4G disabled first otherwise you'll need to reinstall Windows. Also, disable Windows 7 Installer and Windows 8.1/10 WHQL and fast boot and MSI fast boot, that whole page of boot options should be disabled.
