polaris vs pascal, vega will be on october, announced probably dunno about release

I believe this is the 980Ti problem ( V 6th card ) . ( but that's for the miner. And if OS do not see 6th card - jumped riser might help.

I like puzzles like this. Have you had 6 cards working in the same rig as the one currently failing with 6x 980ti?
A rig that previously worked would have the correct BIOS settings already.

I'll jump ahead assuming you have already proven your HW and SW and know where I'm leading, It may be the number
and model of card that is the problem. 980ti's have 6 GB mem so that is 36 GB to support. Just speculating, I don't know if adding RAM or swap would help.

if you're not yet fully invested in the 980ti you may want to wait a week for the 1080

however - the 6 card issue is ONLY with the 980ti cards ... it seems even the amd 280x oc / 7970 cards ( one and the same ) never had that issue either ... 6 cards and no problem ...

im sure its a bios issue - as ive seen 8 gpus in a single system run by an expensive supermicro motherboard designed ( with a large capable bios ) for such things in hpc servers ...

but i will research your suggestion - as it could also be an issue with the way the 6th 980ti card is allocated in the bios / motherboard ...

Im on windows 10 x64   , It will never be possible mining ethereum with windows 10   .

not with h81 pro btc, it has two molex each molex deliver 132 x 2 = 264w total

now you need at max 75w for each slot, to be provided for each gpu, so at best 450w

a motherboard alone can provide 200w(25w for each x1 slot, you have six of them plus 75w for the x16 slot)

math is telling me that you have a maximum of 200w+264w=464w, more than enough for powering any six gpu combination out there

and actually no card draw 75w the maximum that is allowed in each pci-e slot

I don't think you understand what someones life is like. Everyone has different skillsets, lets look for a moment at you or me completely changing. Spending a couple years learning a different set of skills is not all that different that starting a giant company. I could more easily start a new company then learn to program to the same level of quality as current releases are at, let alone at yours. For me that's a complete waste of time because my expertise are in other areas. I pay people instead to do that work because that's not where my expertise is. I can't pay for what people don't sell or don't even advertise openly that that's what they sell.

Most people don't know the market exists because you don't present your wares and there is no market to actually buy from due to back room trading.

Not just that, but what market there is isn't a free market. You don't advertise prices and even then you sell them to whomever you want. You've even mentioned you only sell to a handful of people (which are big players in the crypto game, which further pushes down all the other miners) keeping it completely exclusive. This pushes other miners out of the market due to the nature of mining.

There is no other game in town for AMD. The current alternative is SP and friends, which is why I switched to Nvidia. Ethereum completely fucked up your stranglehold on AMD mining, but no one could see that coming.

No, you can't mine etherum with windows 10.

And @ Crysx:  did you try with simple cheap unpowered( or powered) riser with pin A1-B17 shorted - on 6th card? That solved my 6th card problem few times.

windows 10 is okish too for those card with the right drivers?

AMD has to workaround for more than 4 cards on w 7, but W 10 works with 6 cards ( I'll try 7 soon ). Nvidia works 6 cards on w 7 but some strange things from time to time happen.  I have several rigs (with 6 nvidia ) and some need 8+GB RAM some not, and last fun is AMD mobo: 6 cards work only one way, if I change position(slots) of 2 cards- only 4 start ( AMD cards, 380 ). To me looks like mobo switches off PCIe in case of smallest irregularity. Usually that is fixed with trying risers (I have them all types) and to me was good idea to short pins that signals "it is GPU" to mobo  ( here:   http://www.gobitgo.com/articles/1001/How-To-Correctly-Use-and-Install-PCI-E-Riser-Cables/  )
