990FXA-UD7 6 GPUs problems

[chm]

Hi,

I'll be upfront and tell you right away that I am more than tired of this motherboard. It is the absolute worst I have ever bought. It's also the first GIGABYTE, after years of ASUS.

That said, I don't want to send it back just yet. I am looking for the right configuration to plug my 6 r9 280x with 1x-to-16x PCI-E riser cables. I've gotten at most 5 cards to be recognized, but nothing more. I know both the card and the slot are not faulty. The problematic slots are the last two. They sort of alternate being detected.

Any ideas?

Bump.

I'm not at all surprised that this very simple question gets no answers. I really don't want to be mean to anyone, but this is a make it or break it for GIGABYTE. I build computers for cryptocurrency mining and I was very excited about the 990FXA-UD7: 6 PCIe slots, AM3+ socket. I post my builds online and I will make whatever I can to prevent people wasting their money on this complete failure of a board.

So here I go again: Can the 990FXA-UD7 accept 6 GPUs, and if yes, how?

All I can say is not (m)any around using this many GPUs hence little replies - I thought quad support is all there is.

I was referred here because these are apparently the official forums.

You would think that a MOBO with 6 PCIe slots would accept 6 GPUs no?

Have you tried posting this question over at the TweakTown Forum? This covers North America for Gigabyte and there may be more users over there who can help answer this problem.

I know of some users who have used 5 GPU's but you are the first to ask about 6 and I don't know the answer. Have you tried asking Gigabyte Technical support? http://esupport.gigabyte.com/Question/Tech?Country=Canada#2

I have actually tried to create a ticket on Gigabyte's website but their registration is apparently down

I've just posted on TweakTown, thanks.
