Hello Everyone,

I have been trying to install 6 Graphics card on my H81A-BTC V20, but I'm only able to get 4 of them working, I tried replacing the risers here and there, the one that doesn't work, starts working whenever I disconnect the other one.

My motherboard has no feature like 4g decoding and so on...

In addition to it, I tried disabling the built-in graphics card, it didn't work too, didn't help me to add up another pci e card.

Also, I'm using windows 10 and tried every possible tweak available on the internet such as combining the old 470 non WHQL installer with the other one.

Here's my specs;

MOTHERBOARD: Colorful H81A-BTC V20
RAM: 4 GB
HARD DISK: 120 GB SSD
GRAPHICS CARD: 6 X 580 8GB SAPHIRE AMD

I would highly prefer some help -- FEELING LOST.

Thanks in advance
