Hi,

my rig (Asus Prime Z270-A + MSI 1060) works well, when booting up with 8 GPUs (using 1 M.2 -> PCIe adapter).
When booting up with 9 GPUs (using 2 M.2 -> PCIe adapter) the 9 cards appear correctly in Windows 10 64 Bit (8 GB RAM), but miner (tried Claymore and ethminer) won't start.

See the pics. Do you have any plan, why it doesn't work with 9 GPUs? I heard, that one can't use GPUs in both M.2 slots of the Asus Prime Z270-A, but Windows discovered both GPUs correctly:

you have 10 graphics card under your device manager ,try disabling intel hd 510 in bios

my Prime z270p have the same issue.
8 cards working fine.
When 9+ cards,  windows crashed in few min., even I done nothing.
So I guess maybe the intel chipset driver problem? who knows.
or the z270 chipset  limited by ASUS BIOS?

Do you mean it crash before mining?

Yes
just moving the mouse...

max supported gpu for win is 8 gpu if im not mistaken, anything more than 8 go linux.

Thats what I thought, but then I saw 9 GPU's aside from the Intel 510 on that guys device manager and I'm thinking somethings changed in the latest Win10 update maybe ... worth testing.

What does event viewer say?

The fact that you say see 9 GPU's is good news.

I have a clean install of Win dows 10 64 Bit v1703 (Creator's Update) on that rig. Maybe, that's a reason, why I can see 10 GPUs in my device manager?
But it does not help me to see them in device manager, if I can't start mining on the 9th GPU.
What do you think is the reason, that it won't start on the 9th GPU? Maybe cause I put PCIE adapter in both M.2 slot?

I could recheck this, when my PCIE splitters will arrive.
Maybe in the meantime I can also check again and look in the event viewer. Where exactly should I find the reason?

One said here, "for more than 8 GPUs got to linux". But which linux distro does support more than 8 NVIDIA GPUs? I have read that ethOS and simpleminingOS are also limitted to 8 NVIDIA. Or am I weong?

Have You solved?

I touched similar problem at the border of 7/8 GPU, increasing virtual memory solved.

try  nvOC, there are a few 9 cards mobos in its fully supported list, find it in this forum.

I tried with 8 GB RAM and 20 GB virtual memory. Did not work.
Won't switch to linux now because only 1 GPU more possible.
Isn't there a solution for Win 10?

Today I tried it again, and disabled the integrated graphics controller of my Asus Prime Z270-A mainboard.
Now only 9 GPUs are showing up in Windows device manager, but the same problem: Mining does not start.
Does anyone has a solution or work-around for that problem?

the solution is to run less cards if you wont try another OS

Which OS does really support more than 8 NVIDIA cards? ethOS and simpleminingOS are saxing both max. 8 NVIDIA.
Or which OS do you think gan handle more?

My friend had the same issue. But, you know, it was all gone, when he moved to Linux! Try this platform too!

Did your friend use NVIDIA or AMD cards?
Which Linux distribution do you suggest for NVIDIA?

enableG 4G decode from bios

I did of course enable 4G decoding, otherwise I wouldn't even be able to get 6 cards working. Here we are talking about the difference between 8 and 9 GPUs, if you missed that part.

Windows 10 only supports up to 8 unless you mix up Nvidia and AMDs. If you want 8+, go with Linux

Which Linux distro does support more than 8 NVIDIA GPUs?

This might be correct.  Anyways I have 9 gpus working on Win 10.  AMD+Nvidia cards.

Im currently running SMOS(find it in another thread here on the forums) with 11 Nvidia GPU`s. Its is based on Ubuntu, costs 2usd each month - Works very good, i recommend using it.

OP can you please try using half the cards in Claymore, and the rest in another miner?

I have 9 GPU working but is a Mix of 8 RX 580 and 1 GTX 1070, I can add more GTX 1070 but zero RX 580 because  windows 10 only supports 8 of each Nvidiai + AMD mix as far as I know.

The fact that you can see 9 of the Nvidia on device manger with no error is good start since we always see some type of error when adding more then 8 of the same.  

Have you try with claymore 10 ?

WRONG :)

to set up any rig with 12 gpu its easy with the right motherboard , you must to have 6 nvidia and 6 AMD cards , this way the 12 cards setup under widows can not be a problem , really easy to set up . if you want 16 cards it is still possible under windows (10) but might be PITA (pain in the ass) to set up , but once the right configuration is set , you are ready to go :) i have both 12 cards setup and 16 cards setup running without any problem under win 10 enterprise edition :) amd cards are with custom bios , latest blockchain driver , driver patch , nvidia cards overclocked/ undervolted with software :)

Hes not wrong, max 8 GPU is what windows officially supports at the driver level for each unique driver. So 8 GPU's that can run off of AMD drivers, and 8 GPU's that can run off of Nvidia drivers. If there was a third co, we could add 8 more, but the max is still 8.

you are WRONG too :)
I tried to run 10 amd cards under windows and worked fine :)
do you have any experience building rigs ? modding bioses ( modding , not just changing mem staps) , modding mobo bioses )
or just reading articles about what possible and what not  ;D
its really pita to set up , not a real plug and play solution :)

Show us pics then, of 10 AMD cards mining under windows, if you have achieved it. If you dont have pics, then stfu and crawl back to your hole of ignorance.

Can you share some pictures of your miner running 10 AMD on windows 10 ? I would love to see that.

 ;D i dont think i need to prove anything for ppl like you  ;D
  ;D "stfu and crawl back to your hole of ignorance"  ;D
that is what you should do right now... if you asking me on the nice way i would be happy to post some picture as i always did when i posted something on this forum , but never going to share how i did it :)
im not the only one who built a mining rig with 10 cards under windows :)

Not to long ago when many of us was running a 8 card setup without any problem , anyone was able to buy a 8 cards setup miner computers from a forum member here on the forum , this is what you said about any 8 cards setup ...
Times changed , you learned a lot in the past few months , now you think 10 cards setup (same kind ) is impossible :) JUST WAIT ANOTHER 6  MONTHS , BY THEN YOU MIGHT GOING TO FIND OUT HOW YOU CAN DO 10 CARDS SETUP EASY ;D ;D ;D

EDUCATE YOURSELF , LEARN TO SPEAK ,  ASK NICELY , THEN YOU GOING TO GET ANSWERS AND PICTURES , BUT TILL YOU CAN NOT ARCHIVE ALL THIS I CAN NOT SAY ANYTHING TO YOU , JUST WHAT YOU SAID TO ME : "stfu and crawl back to your hole of ignorance"

HINT  ;D :D ;) ::)
as you can see in the first post , 9 cards showing up under windows device manager , its actually 10 cards (incl itel hd 510), so windows ok with the cards , but the miner program is not ... think strong :) why windows ok with 9 cards ( the same kind ), working fine , no error under device manager but the miner program is not running fine ? Go to the details deeper , you might can find the answer  ;D  ( did you see the "hole of ignorance" )  ;D

Says EVERYONE who has nothing to back his/her claim, forget how you did it, you cant even share pics of the result, and expect to be believed ...


True, I lived, I learned. Till then the only people who were successfully running more than 7 cards were doing so on modded bios'es on Z97 motherboards. h81 or h85 boards did not support more than 7, Then came the Z1xx series which was a disaster for mining, but with proper bios mods the Z170's could support 8 as well. But the real change came with the Z2xx series when everyone and their mum could run 8 cards easy.
I learned from people who had actually done the 8 card setups and could demonstrate/prove it, so that changed my attitude towards the max no of cards.


Yes windows can see 9, 10 even 11 GPU's in my testing, but they will not work with any GPU intensive program, so the maximum usable cards is 8. More than that and the system crashes.
But ill leave you with a nugget, get in touch with jstenfanop on these forums and hell "Educate" you on max GPU limits, what you can and cant do etc. And next time when someone asks for proof, show up or shut up.

 ;D be patient my friend, dont be mad or angry just bc you dont know , dont understand something  ;D your time will come ... few more months and you will see the light again ... just like you saw the lights after 6 months about how 8 gpu can work with one mobo  ;D

soon you are going to post something like you did in another topic about that 8 gpu and one mobo few months ago :) just be patient and learn about new things  , dont refuse something just bc you think its can not be done :) give yourself a few more months , (in your case you might need a year , last time is take you 4 months ) , be nice with another forum members  ;D


HINT:
If you already have Asrock H110 Pro BTC+ or BIOSTAR TB250-BTC PRO  you have better chance to find out how is that 10 gpu (amd or nvidia) build can be done  with windows 10 enterprise ( let me help you a little bit , its a 2016 LTSB ) ;D



To me looks like you changed your attitude after finally you was able to run 8 cards , not bc another ppl demonstrated/proved  , but bc another members helped you to archive that ;D

Another post without any proof of any of your claims, or without any substance. You really dont have anything better to do, do you?

Where's the logs from the miner? That is where your info is. They will tell you exactly what the software is seeing and reporting. No one cares what the device manager and task manager say, and the mining software is not using verbose, so you have nothing to show us. We need the logs, and you will likely not even need us once you look there and see the software telling you exactly what is wrong.

Oh I see, luckily I read through every single comment in this post, and really appreciate of your hint. Seems like new windows version supports more than 8 GPU, anyone know what is the max?

AsRock motherboards seem to be good for mining in general. Even very old boards with 4 or 5 slots can do 8 cards just fine by using the correct PCI-e slot multipliers. Now, I wouldn't doubt about this guy's claim that it's possible to run more than 8 Nvidia cards. Maybe someone who really wants it can put a bounty up somewhere to make a bios modification for his motherboard to unlock the maximum of 8 cards.

Windows can support only 8 cards of one brand. simple as that

looks like windows limits to a total of 8 gpu units.  Go linux!

If you have >8 gpu better using Linux.

It's really simple if your use ewbf or Claymore
You must do only 2 things.
1-just download Linux version miner, paste your configs and run in on new OS. (really! like CTRL-C - CTRL-V)
2-of course install videodriver.

well ... well ... look what just happening (https://bitcointalk.org/index.php?topic=2298574.0) .... ppl with a little bit more knowledge than you have , starting to discovering the possibility of windows 10 and 8+ GPU's  ;D ... as i mentioned to you earlier, of course its take some time ... for some ppl a little bit longer ( for you maybe a year ) ... for some ppl who know what and how to do a little bit sooner  ;D

Sooo your claims of having run 8+ GPUs a months ago with no proof/not even a screenshot whatsoever, followed with nonstop shittalking is somehow justified today because Microsoft enabled 8+ gpus in a Windows update?
I can claim that I invented anti-gravity shoes, refuse to give anyone any proof, wait till the day they are invented to come back and shout from the rooftops "See some people with more knowledge have started to discover anti gravity boots".
I feel sad for you, you must have little else to derive any pleasure/sense of accomplishment from, so im going to walk away and let you enjoy your moment of "Sound Logic".

no... i said some ppl can do things with windows what you can not ... bc you dont understand and you can not imagine how its possible ...
i said , you going to need some time to find out how ... but actually you really never found out , you was reading that on this forum , its now possible , its mean someone else put this information front of your nose  ;D
i was not the only one who was able to run more than 8AMD or nVidia cards under widows ... a months ago ...
I did not give you any prove bc , you talked shit to me ...

And after all your BS talk ...


EXACTLY A MONTH LATER  ;D
Look at you how excited you are now , bc you think you dont have to do anything just updating your windows :) so you have a kind of plug and play solution , instead of many hours hard work to find out how it was possible a months ago  ;D HINT : dont think its going to be that easy !!!

Hello Mensa84

I have EXACTLY the same problem as you in this topic !

Did you find the solution ?

Thanks !

Alex

make sure that the power supply can support your nine gpu
you need to calculate the total supply needed,
also try to attach every card at a time, to see if your gpu , or the riser is the problem
many made mistakes regarding this me im also a victim before but after few months
and research finally got my break and after that my gpu never stop, unless its brown out
that can only stop from mining,
