Why do you want to run that crazy number of cards on one machine in the first place?

Why do you want to run that crazy number of cards on one machine in the first place? Why not.. Better w/h ratio ..

That's not even factoring in the pain of getting such a machine built in the first place, the higher costs of building such a machine and getting everything coordinated, and getting it to even start mining at all. Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: Amph on May 21, 2016, 07:24:52 AM man think about this for a moment, one new rig cost only to you $200 for the "unnecessary parts that don't mine" that you want to remove by using splitter so you can do 12 gpu rig instead of doing 2 rig with six each
are you sure that saving 250 is enough to cover the expenditure for adding pcie splitter on the only rig you want to run? remember that psu are needed anyway, riser are needed anyway, other components(MB, CPU, RAM, SSD) like i said cost only $200 or even lower...not worth it sitck with six gpu rig Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: smolen on May 21, 2016, 08:13:02 AM so I think computer motherboard, BIOS, windows system is not the problem, I remember a rumor about splitting PCI lanes between virtual machines, so the work was done BELOW driver level.it can more than 13 gpus, AMD drivers should be restricted work I think the key issue is the AMD drivers Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: bathrobehero on May 21, 2016, 12:53:50 PM I was thinking about doing this just for the challenge (with nvidia in windows) and I also like the idea of it but I decided no to even try because it's very impractical and it would cost more than 6-card rigs.
Basically, the only things that you would save money on is the motherboard (which is relatively cheap), HDD/SSD (even cheaper) and windows if you were to use that. On everything else you'd have to spend about the same amount of money (per card) as you would for 6-card rigs because from experience RAM and CPU pretty much has to scale with the number of cards if you want to be able to comfortably mine all algos without running into bottlenecks and you'd also need risers, more PSUs and of course the splitters and so on. And even if you'd get it to work but let's say it would randomly freeze or something else, good luck figuring it out without going insane. Sometimes that's pretty annoying even for 6-card rigs.

I use 8GPU in a system, 2x7990 + 4x390. there is no difference if I use 4GB or 8 GB memory. I need more PSU though.

Like duals using the same PCI lanes to begin with. Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: WarrEagle on May 27, 2016, 05:18:27 AM Just Don't. Getting 6 cards running is enough.

i;m try to o 12gpu my email t3000@qq.com i'mchina how to help you remote ? Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: pehoko on May 27, 2016, 09:55:12 AM It is non very clever idea to use many cards in one rig. If single gpu crash then entire rig may crash. From my opinion 3-4 cards per rig is optimum.
Title: Re: Reward 1BTC , Let AMD drivers work more than 8 gpus Post by: jstefanop on May 27, 2016, 06:06:16 PM I have 10 GPUs running in our linux rigs. Will post an announcement soon as I will put them up for sale, but you can contact me if you want to know how its done.
