Just wanted to Verify!

Ive heard some rumors that its now possible to use more than 8 cards on Windows 10 systems, so shutdown my rigs and mixed up one with 10 Nvidia cards, thats now doing rock solid on all 10!  The 1709 Update fixes this limit.

Can anyone confirm what the limit is now?
Can anyone confirm that its the same for AMD cards? I Don`t have enough cards to verify this at the moment.

https://preview.ibb.co/hvPrMR/10nvidia.png (https://ibb.co/hoguam)

great news, more hi-end rigs are coming.

There is no 8 GPU limit for nVidia. It is for AMD only.

There is. Windows (at least 1703 or older) sees 9 or over nvidia cards, but miners don't work.

The question is, does one want to have more than 9 GPUs on a Windows computer?  ;D There are far more suitable options than Windows for this.

Well, I'm curious. Someone who will try that? I have mobos max for 8 GPUs :D

Oh! Wow. That's a start.
I've had some big issues with Linux based distros built for mining lately and I had to shift to Windows for the same.
It's good to hear that you can run up to 10 GPUs on Windows OS now.

Probably possible with more than 10 GPU`s, but i dont have any more.

Latest update of Windows does not work so well with AMD Blockchain drivers.. Hope they will update these soon.

The limit may be removed from windows but there is still a limit on the amd drivers, so unless you mix amd and nvidia it won't work yet. You can always go with linux and plug as may cards as you want.

I saw a motherboard which supports 16 GPU. And probably Windows too, can support this motherboard.I just don't understand why you need it. I doubt that you have so many towers that there is not enough space to accommodate them. If you use old equipment only with the use of a new GPU you will get the same speed with less effort.

I wish I was near my rigs, im dying to try this out. I need to see if this works with Nvidia non-mining cards, and then for AMD cards.

The AMD blockchain driver works with the v1709 build but the problem is the Windows UI becomes unresponsive and unstable. I did a clean install back to v1703 until a new driver is released. Supposedly there will be an updated driver later this year that will increase the maximum limit of 8 of the same GPU type in Windows 10. Looks like the driver that ships with Windows v1709 fixes the 8 card limit for Nvidia. There is also a beta driver release from AMD for the v1709 update, but I didn't try it since it probably doesn't include the Dag fix.

https://www.guru3d.com/files-details/radeon-software-crimson-relive-fall-creators-update-beta-driver-download.html

Apparently it has blockchain drivers in it as well.
http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-Beta-for-Windows-10-Fall-Creators-Update-Release-Notes.aspx

That's the Relive driver release, which don't include the blockchain driver fix. The driver that ships with v1709 also works (didn't test if it removes the limit), but doesn't have the Dag fix and the blockchain drivers cause the Windows UI to be unstable, so hopefully AMD will update the blockchain driver for v1709 as well.

Just did the update, but w10 still becomes unresponsive and the miners crash when installing the 9th card.
I'm going to remove all the drivers and start installing them manually again one by one. (13x1080ti)

I just told you it has blockchain drivers in it...

Saying it does and confirming it does are two different things. The release notes for the beta Relive drivers don't say anything about including the blockchain drivers.

I only have 7 580's so I can't say if 8 card limit on Windows is Removed but I installed 1709 and the drivers dropped the cards dropped to 24MH. Some things I found:
- Using Autologin my start button and action center do not work
- Task manager now shows GPU stats on the perf tab, all 7 GPUs are there which is neat
- I had to DDU a few times to get block chain drivers to stick, Windows kept auto installing even when set not to, I finally set with GPO, not sure it that was needed but it is working now
- I cannot shut down the computer anymore even with power button, it just bounces back to logon screen, restart works fine

Has been completely stable mining 24 hours now

holy crap you are dumb lol  :o

Smarter than an idiot that thinks the Relive drivers include the blockchain dag fix. LOL

haha ok, you'll feel like an idiot when someone bothers to hold your hand and show you.  Ain't going to be me though.

You got that right!

Quick update: tried reinstalling all the drivers, still no luck though. Max 8 cards of the same spec. Btw I'm running W10 Home edition, maybe it works on W10 Pro?

So, I read through the thread but still can't seem to say I found anyone actually confirming this is the case yet. Even if it only supports Nvidia cards atm, I would be interested in someone who has actually ran more than 10 cards successfully on the new version of Windows chime in.

Absolutely right...!!!  8) :-*

Ehm... What?  ;D ;D

That's good point, there might be the difference too.


So who will test that? Everybody was exciting from mining mobos with 10+ PCI-E and bought them, seems like actually nobody have them :D

This is the setup where i use 10 cards;
7x 1070
2x 1060 3gb
1x 1060 6gb.

If i add another 1070 card, that card will not install in windows, same thing if i remove the three 1060 cards, the last 1070 card still wont install on windows(Works fine in another computer). Maybe there is a limit for the same type of cards? I dont know. Before latest windows update, i was only able to use 8 Cards of NVIDIA no mather what mixups where used.

I use W10 Pro. 8GB of memory and G3950 CPU and Asrock Pro BTC+

I've managed to install all of my 11 cards:
 - 4 x 1070
 - 2 x 1050ti
 - 5 x 1060 6GB

I'm using Win 10 Pro, changed to Gen 1 because after card No.8 Windows wouldn't boot using Gen 2. I'm using Claymore Dual miner 10.0, no problems so far except MSI Afterburner is not working and Nvidia-smi wouldn't let me change the clocks of the cards.

Good News!
Hope this come true soon, so that I can plug 19 RX570 on B250-MINING-EXPERT.
Lowering cost of CPU, DRAM and disk. ;)

Windows 10 fall creators update(1709) + AMD driver for Fall creators update v17.40

Tested with 10x  RX 570 . Working good all 10 cards.

But no Dag Fix in new amd driver. each card 21-22 Mhs only.

Have you tried Nvidia Inspector to overclock?

Would you mind taking a screenshot that shows both the device manager with 10 GPUs and claymore mining with those 10 GPUs?

Also, have you tried the blockchain driver with 1709?

If you have managed to make 10 cards working then you should try at least to modify the bios of one card if all RX570 are same brand and same memory. If it works well and you can make it go up to 29 mhash then go and modify all the cards because it adds up quite some , up to 80 Mhash more or about 0.00055 btc more per day which is not bad with the actual bitcoin price.

Great news for such limit to be removed.

new future creators relive beta drivers have gpu workload switch so you can switch between mining and gaming drivers apparently...
https://www.techpowerup.com/forums/attachments/capture-jpg.93168/

Its not worth 8 rigs plus, given the stability loss due to more risers, more moving cards, potentially more PSUs etc.

A closed chassis 6 GPU rig is still steal. I've tried 4, 6, 8 and 12 GPU rigs. Win and Linux.

Yes. I have tried blockchain driver as well. its allowing only 8 amd gpus in 1709. more than 8 windows is crashing.

They are all bios moded.. 29+ Mhs with blockchain driver. with new windows update and new amd drivers v17.40 its showing more than 8 gpus and mining also working with claymore 10. only thing is no dag fix in new amd driver. so less Mhs.

have, (need use GPU workload-Compute) see this video on 48 sec

https://www.youtube.com/watch?v=XGHC1M0HSe0

I will give a try tomorrow and will report if it works.

Here's a bit more info from STH forums on a working 13 x 1080 ti setup :)

https://forums.servethehome.com/index.php?threads/13x1080ti-windows-10-1709.17184/

No, hes got to be tortured with the fucking sadistic Linux.

Also got it working :), 12x1080ti on a asrock H110, setting the pcie lanes in bios to GEN1 did the trick.
Seems quite stable atm.  GPU Tweak sees all the cards so that's also a good thing.

Did you notice any reduction in the hashrate because of the change to Gen1?

The accomplishment right now would be on the asus b250 mining expert board, supporting 19 gpu's.

More than 8 AMD gpus working on h110 pro btc motherboard with Windows 10 Creators Fall Update 1709 + New amd 17.40 driver.

Changed workload setting from Graphics --> Compute in Global readon settings for each card.

I tried 10x RX 570s . all working fine. 29+ Mhs each.

did you working afterburner?, i cant overclock memory. Back to blockhain driver and max 8 gpu= working.

Why would you need afterburner for AMD cards? OverdriveN tool should work just fine. I understand the reasons for using MSI AB with nvidia cards (voltage curve, fan curve etc), but can't think of a single reason to use AB with AMD cards.

try overdriveNtool 0.2.1 with asus 580 8 Gb strix but not working.

afterburner not working. overclocked in claymore (-cclock  and -mclock). working.

did you used beta version of ab?

i couldn't run more than 6 gpu untill now. maybe this time it will work.

Confirmed. 10-GPU (mix of 1060s and 1070s) mining rig working on Windows 10 version 1709.
This is really great news especially for new miners who will no longer need to deal with the less user friendly linux os.

Also running afterburner 4.4 beta 12, works without any issues. Can overclock nvidia cards normally.

I'm kind of on the fence with this 8+ gpu thing. Got a couple of 8 gpu rigs myself, and while I can add at least 2-3 more cards to each, I don't think I will. Each gpu+riser add to the complexity and potentially lowers reliability of the whole system. And also when a rig goes down for some reason (PSU/MB/HDD/etc failure), you're losing more money during the downtime.. It's great for larger miners I guess, but for someone with 20-40 GPUs in total, I think I'll stick to 6-8 cards per rig for now.

That is good to hear, nvidia is blockchain driver hassle free, amd users rely on the blockchain driver. Now, AMD needs to update its blockchain driver.

I think they merged their "regular" and "blockchain" drivers now, the latest 17.10.2 driver has a toggle for "compute workloads": https://www.anandtech.com/show/11959/amd-releases-radeon-software-crimson-relive-edition-17102
So that's probably how it's going to be now, just one driver with a toggle instead of separate blockchain and gaming drivers.

I have to ask. how did you power so many gpus if they need 6+8 pin ?

PSUs only have 8 6+2 connectors so it's limited to 4 gpus. even dual PSUs supports up to 8 gpus.

unless your GPUs only use single 8 pin connectors?

8x of my Nitro+ 580s happily hash 30+ with only the 8pin connector plugged.

Hi Guys ,
               Now its possible to run upto 12 AMD GPUs on Windows 10. Check my post

https://bitcointalk.org/index.php?topic=2317091.0

Can someone pls who install the newest AMD driver try WattTool http://www.overclock.net/t/1609782/watttool-a-simple-tool-that-combines-overclocking-with-vrm-monitoring-tweaking-for-rx-400-series If it's working again since Overdriventool is not working? Thanks.

Can anybody confirm this?

Can't get it to work with Biostar TB-250 BTC Pro and 12x GTX 1060
8 cards work perfect, when i add one more after installing drivers system crash and windows do not boot up.

Windows version 1709, drivers 388.13, anyone have any solution? :)

Gen 1 ?

I have the same mobo, 8 GPUs and it doesn't work if PCIE isn't in Gen 2.

Tried auto and Gen 1, the same result. Switched these cards to other rigs and i made 12 x rx570 with ethos on this mobo.

So you got it to work with 12 nvidia on windows with Gen 2?

I only have 8 Nitros so i'm unsure if this would work on yours too.

Try it, you won't lose anything anyway.

there is no limit for nvidia cards only amd drivers block more then 8 cards...

I've seen reports from people not being able to run more than 13 nvidia cards in one rig. Didn't try that many myself so can't say for sure, but those who tried it said that they could add more amd cards to that same rig (up to 19 cards in total), but not more nvidia cards (so the rig would work with 13 nvidia + 6 amd, but not with 14 nvidia cards).

nice information thanks man  ??? ??? ???

That is a very good information thank you for this post.

You could go 13 Nvidia cards and 6 Nvidia mining cards. That is the secret !

It's not a secret, we're probably reading the same forum, I also saw that message about mining cards working. :) I just don't think that mining-specific cards (especially the ones without video outputs) are a good investment for small miners so I didn't mention those in my previous post. But yeah, 19 nvidia cards should work if 6 or more them are the mining edition cards.

All - The following is my email exchange with ASRock support.  Thought it may be helpful to others.  The 'hack' below did NOT work for me.  I had to roll back to an earlier build AND had to do the hack.

Rig:
H110ProBTC+
Trying to build 12 GPU rig, can only get 7 cards running
8 - 1060 EVGA GTX GPUs
8 GB RAM
Windows 10 Pro 1709

I am still having issues with this motherboard.  I have a somewhat bizarre situation.

Regardless of the number of GPUs I have installed in the MB, device manager throws a code 43 on the 3rd from the bottom in the device manager list.  Meaning, if I have 10 cards installed, the 8th card is not working and shows code 43.  If I only have 6 cards installed, then the 4 the card throws the code.

I've used DDU to uninstall and then reinstall Nvidia's drivers at least 4 times.

Thoughts?

ASRock Support:

Hi I am trying to get 12x 1070 running on Win10/Biostar BTC-250PRO
ATM getting WHEA uncorrectable BSOD, putting it down to driver or installation issue but now worried I cannot find any confirmed details of Win10 systems over 8 NVidia GPUs.

@roptix did you have any joy?

yes, I success to use more than 9 GPU's Nvidia on Windows 1709.

Once again I was struggling with this upon adding a sixth card. Only 5 were seen at first and then I plugged the sixth one in  ::) DOOH! Then when I reboot only 5 again but 1 had dropped off and another came on. Tried changing drivers. No change. Then when trying to change again, windows said gtfo and refused to play anymore.

so
I rebuilt my usb bootable with the new 1709 . loaded it up :spinning wheels: and all 6 show in device manager! Driver that loaded is 388.13
mining like a mofo!

This is going to eventually be 12 1060 6gb on a custom built frame I made.

I can make anything you can think of as long as it is LxWxH
Normal stock size is 20L x 14W x 10 1/2H for 6 gpu
and 24 x 14 x 10 1/2 for 8 GPU and 2 PSU
I just made one that was 17W 25W x 7 tall with PVC instead of wood.

Really? Can you show us screenshot of all 9 cards mining at same time? As far as we know, Windows 10 does NOT support more than 8 nvidia cards.

i have 2 rigs and both with 12cards nvidia and no problem, maainboard biostar tb250 pro and win10, i am using nicehash.

That is not even true...
Win10 64bit can support almost unlimited number of gpus.
It was always drivers or hardware limitation, nothing more.
Guys, please do not repeating this myth again, again and again!!!

Lot of people say they run more than 8 nvidia cards, but nobody wants to show screenshot with 8 cards mining in action :D

Works well for more than a month already.

Still no screenshots, just talk :) I can get 15 cards in device manager, but show me them actually mining all at the same time.

Believe me now?

What miner is this?

Now I do! How did you achieve more than 8 nvidia cards under Windows 10 ?

Assuming that you're talking about the ETH miner - it is Phoenix Miner.


Use the latest driver and 1709 update. That's all you need, assuming that you have setup the motherboard properly.

I've also made a guide on how to get 13 cards but it was ignored.

Awesome news, thank you very much for this kind of information.
On Gigabyte official website they say "Windows 10 version 1703 64-bit or higher is recommended"

Must rise virtual memory, i suggest minimum 40gb in your case.

Min 40gb and max ? How much ram do I need ? Wat do I need if I want to add more gpus ? Thanks

Chill kid . Anyway does not work ... I have 16gb ram my virtual memory “says” that the pc use 2938mb  and I have 29547mb free space . I can’t put max memory to 40000mb... . I put it to max 29547mb but Ethminer crash.
Other solutions ?

Does this work on LTSB or only with the fall creators update?  Would much rather not use the bloatware versions of windows.

Any way to slipstream whatever small change was made into LTSB?

larger storage space so u can increase virtual mem.

Im running 10 GTX (1080, 1060, 1060 and the balance in 1050TI) on my Asus B250 Mining Expert m/b on rig 2 with a 850w and a 650w power supply.  On rig 1 I have 7 cards currently until I replace a bad fan on a power supply of mine. That rig has RX570, (4) RX580, RX560 and a GTX 1060 on it. Rig 1 also has a Asus B250 m/b. Stable as can be and making me that $$$. I run 120gb SSD on each.  Rig 2 has two 4gb 2133 memory and Rig 1 has only one stick of 4gb 2133 (until I receive the 2nd ordered 4gb stick of memory).  So far Rig 1 is stable but I just shutdown a 6gpu m/b rig and transferred it all to my 2nd Asus B250 m/b.  You have to have windows 1709 update.

Hey guys just wanted to let you know this works in Win10x64 LTSB so you don't have to use the bloated Pro version.  

I've moved on to HiveOS though and love it much more.  But it's worth noting.  Also to get afterburner to see it just reboot the computer after the drivers are installed for 9th card.  Same as you have to do with less cards.

I'm formatting my drives so here's a pic while I can for you pic people. ;)  It does work.

https://s9.postimg.org/mdx4kv9jf/ltsb-9x.jpg (https://postimg.org/image/mdx4kv9jf/)

I don't know if the special upgrade included in the fall creators pack was included in some smaller update, LTSB doesn't gets loads of updates like other windows versions or if it matters on the kind of adapters used.  

I'm using these adapters: https://www.amazon.com/MintCell-Adapter-Mining-Ethereum-Monero/dp/B077F4VCHR/ref=pd_lpo_vtph_147_tr_t_2?_encoding=UTF8&psc=1&refRID=MTJPG2N52QZ5TRC0J5YY

It made more sense to me to use those since each risers still gets individual power vs the adapters that share the power.

I use win10 64 1709 pro debloated. Asus B250 mining expert with 13 RX580 GPUs. Virtual mem. set to 80 GB on my SSD. Output with claymore 11.3 on nanopool is 398.5 mh/s and phoenix 2.7c is 396-397 mh/s. no faults or errors. just stable mining. However profits are dwindling fast it seems. All altcoins constantly going down compared to the USD.

What is the version of your LTSB? I am using Win 10 x64 Enterprise 2016 LTSB Version 1607 OS Build 14393.2125. Is this version with AMD Adrenaline Edition driver enough for more than 8 GPUs?

I have installed 16x 1070ti without any problem on win10

How?

If there is power problem around your location that time you will get the more trouble on mining with the windows 10 OS. Initially when I started mining with the 10 RX 470 cards I have seen that good work from this os and I was using the awesome miner software to mine.

With in some weeks when the power automatically shut the rig work. Then when I restart I have seen many trouble with the win10 OS.
Then I have moved to the perfectmine OS to continue my mining work.

Don't know about AMD, and I don't remember which LTSB version it was off hand. But I still have the ISO though, so I'll check when I get home in a few days.

You can see it in Windows settings/System/About if you have remote access. Thanks in advance.

I formatted those drives and moved on to HiveOS.  It's mentioned in original post. ;)

Win 10 x64 Enterprise 2016 LTSB (Updated to version 1607 OS Build 14393.2125) and AMD Driver Adrenalin Edition 18.3.2 support more than 8 AMD GPUs. I tried with 11 without any issue.
