So has anyone figured this out? I have this mobo and cannot for the life of me get any of the 1x slots to work. I can use all three 16x slots, but windows doesnt detect anything when i use the 1x slots...

Thank you for confirming that running 8x HD79XX gpus under windows is possible. As far as I see, most people are limited by 6 or 7 gpus. Is there any tricks to do that?

I'm also quite interested in it. There are many threads on this topic but no successful results yet. You might need to install Linux and use some kind of virtualization to break the 8-gpu driver limit.
How well do you guys think this would work to add more GPUs to your machine? Would you be able to turn a 6 GPU machine into a 9 GPU? Are we still going to encounter issues with the motherboard seeing it? Very interesting concept. The most I've seen so far is 8 GPUs on one machine and that was tricky business.

I'm sorry for that. I just found the link for the guide via google. So there is no way to port the method to the latest driver?
I pretty much wrote the steps for this a long time ago. This website is just adding pictures to my steps.
Also, this guide is invalid for any of the new R7/R9 GPUs (or radeon 7790), as they will not be supported with the 12.6 driver, which enables 6 GPU in win8.

Ethernet wake-up is a good method to power on, and IPMI power-on is even better, but the latter is only supported by few boards.

Re: Motherboard designed for mining, and better riser cables in this thread.
Apparently the PCI-e bus is rated for up to 75W on the x16 bus, but the 1x link is rated for 25W.
I'm afraid that this point is unreliable. I know this is documented in the pcie standard, but some gpu cards seemed to not obey the standard at all and would like to pull much more than 25W from pcie slots even if they are connected through 1x extenders.

Also worth a try to disable on-board pcie devices as much as possible in bios and see if it helps. It's said 6 gpus did work on win7 x64 for some people, at least should be shown in device manager. See:

The maximum number of gpus supported on one board also depends on the model of gpus you are running. Since you can only see 4 cards in device manager, it might be a bios issue and not easy to fix. I would suggest you try the method of shorting pins of A1 b17 and see if it would get more gpus to work.
as per title. i got MSI 990FXA-GD65. i connected 1 master card on x16 riser and other 5 on x1 risers. i did connect 6pin power onto motherboard. power is fine. all the guides mention catalyst 13.1 from techpowerup site or 12.6 from amd website make 6gpu rig happen - though none of them support new r9 290 cards. im now on 13.11 beta 9. device manager only see 4 video adapters. please advise.
It would definitely be wonderful if 20-25 gpus could work in a single system. However, this is not easy at all. There are various limits of gpu numbers coming from bios, OS, drivers, power delivery... Check this thread for reference: https://bitcointalk.org/index.php?topic=64450.0
was sticking to 5 gpus per system, on the cheap base systems I have (gd45 mobos, 8gb ram) but the idea of turning that into 20-25 gpus per base unit would be very entertaining! (Not that I could find enough GPUs to fill it at this time)

Supermicro x9drx might be an option for you, which supports up to 11 cards on a single board. But for AMD cards you will still meet the 8-gpu driver limit.

How about msi big bang marshal? This one has up to 8 pcie x16 slots and is known to work for 8 cards. Current second-hand price is about 150$ in my local market. But I also heard someone said he could only manage it to work with at most 6 cards.
Hi, rjk. It's a great pity that this interesting project was finally failed. You should have made more progress if you had asked help from AMD directly. I heard there was an informal "Multi-GPU" project proposed by AMD last year and finally they got 16 GPUs (8x FirePro S10000s) to work in a single rig successfully. So I think AMD might have already developed a proprietary driver to overcome the 8-gpu limit. See: http://devgurus.amd.com/thread/158863 http://fireuser.com/blog/8_amd_firepro_s10000s_16_gpus_achieve_8_tflops_real_world_double_precision_/
Now I have several questions about the mining pools. Does it need some special permissions to build a mining pool? Or everyone can build one by himself at will?
