Colorful H81A-BTC V20 - 5th Card Doesn't Work!!

[ithebest6]

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

If you have tried everything and it doesn't work you should contact colorful directly by email as only them can help you.

Have you tried updating BIOS ? Maybe this feature of supporting 6 cards is only available through this update.
