Why Stop @ 7 GPU mining Rig.

I am building a 18 GPU Mining Rig with the following bad boy:

Thank you for this.  Have you confirmed this runs 7 cards on SMos?

IMHO, for 6XGPU motherboards, I think mining purposed : H81s (Asrock) and TB85s (Biostar) is the mobo to get.

If you want the 7xGPU variation, then you can either use the PCI splitter method, in which this will be an addon to your H81 or TB85. Although it allows you to do up to 8xGPU, only up to 7 GPU works with Windows or Linux. The 8th GPU may need some custom driver or other Windows Enterprise hacks, to work but I gave up getting on the 8th GPU to work.

OR

Get mobo that supports Z170/Z270 Intel chipset popular for gaming often with nerd-approved features... multiple crossfire or SLI capability, highend hifi sound, blinking lights, "R" - racing stripes, etc.... hence this mobo usually have a lot of PCI slots, which just perfect for mining (although it was not designed for mining). Standard Z170/Z270 mobo usually works up to 4 x PCI slots out of the box (I guess no gamer is mad enough to have 2 x SLIs or 2 x Crossfire configured GPUs). To enable the remaining PCI slots to use for 7xGPU mining.... well thats not straight forward. I myself have the Biostar Z170-GT7, and after many attempts, BIOS upgrades, etc... it just too many things to do to get it to work (meaby... ). However, I know some miners have got them going to 7 x GPUs. I wish they share their secrets so that we know what to do...

** EDIT: thanks to Tummler for sharing his 7xGPU process with the Gaming M5 mobo.

Now, I am working on my 2nd GPU farm, and I decided I will use only the H81 and TB85 motherboard, mainly because it's purposely designed for mining, so it has no-frills features, below $100 bucks or less, need smaller PSU, supports LINUX, smOS and SRR. Using non-mining specific mobos like MSI Gaming 5s, 7s for example; it will be an expensive board for mining unless you have plans to resell it to gamers. Also, it breaks my heart to see such high-end on-board audio and other gaming features sitting collecting dust on the Biostar Z170-GT7.

For smOS to work.... I highly suspect if functionality of an operating system like Linux or Windows, is dependent on a popular gaming motherboard architecture like the Intel Z170 chipset. I bet you that if mobo can run Windows - it will run LINUX and smOS have no issues running on that mobo. Maeby... people have complaint about smOS cannot run on Z170 motherboard with 5 or 6 or 7 GPUs -- but have no problems with smOS with 4 x GPUs or less.

Sorry for long sharing and reading. I know many experts here so welcome any feedback or correct me if I am wrong.

I just got my 7th GPU up and running on an MSI Z170A Gaming M5. So far so good, and if you have a local MicroCenter (I forget if you are in the US), they tend to have several open box discounts. The salesperson I spoke with said they tend to get a lot of returns for this board because it is an entry level "gaming board," and a lot of 12 year old kids end up buying the wrong processor. I didn't know how to feel about that. Regardless, they are available for $100 here on a fairly regular basis, and $120 all the time.

If you buy this board, this is all you have to do to get it working with 7 cards:

--upgrade to the latest BIOS
--activate 4G decoding in PCIe BIOS options
--select IGE (i.e., integrated graphics) as the preferred video source upon bootup.
----there are a couple posts floating around where people state you have to select a different PCIe speed. DON'T DO THIS. It will cause all sorts of problems and is unnecessary since the release of the latest BIOS update.


That's it, and you can run 7 cards with it.

What miningsoftware are you using?


TRY:

Claymore-ETH 8.1 Custom

Used
-wd 1 -r 1 -epool pool.alpereum.ch:3001 -ewal $walletETH.$rigName
Still doesn't work lol.

i dont know the pool now, but one hint i have:

set on Pool Worker same as Rig-Names on SMOS.

than:  -s pool.alpereum.ch:3001 -u 0x2e577Eb55514b083825cfF4Fa51db598621A1F8a.$rigName

Check Again the Config.txt on your flashed drive! it just can be a TYPO, or your router is blocking, but if you still connected to a pool..... the router isnt responsible for issue.

it should look like this:


keep care there is no space.

Hello!

Which miner are you using?

Please let me know, if you get it working, I still can't figure it out :/

Hello,

You will need to SSH access that rig using his LAN IP.

Example:
1) ssh [email protected]
Pw: miner

2) nano /mnt/user/config.txt
Use keyboard arrows to see what is written after EMAIL=*****
Put your email there

3) Ctrl+x
y
enter

4) sudo reboot

You're rig is now mining to your email dashboard.

If you are on windows and can't use SSH, then please install MobaXterm, it's a good software to manage SSH connections.

Hope this helps.

this board works  and does 5 as tested by me

https://www.amazon.com/gp/product/B01N2V0AHI/ref=oh_aui_detailpage_o03_s00?

It may do six I just never tested six.

can't get it to work so far

 -s pool.alpereum.ch:3001 -u 0x2e577Eb55514b083825cfF4Fa51db598621A1F8a.test

My problem is the hasrate that receives nanopool, I lose about 30mh on 390

I ask myself the question, maybe with your bone it will be better ....

I will try to test ..

Yep, new Beta updates (which you need to use yourself) :
- first beta kernel update 4.11
- then beta amd driver 16.60
And the speeds are very close to windows.
And i dont need to tell you how windows vs linux works in other maters

OK, can anyone from you confirm that MSI Z170 or Z270 is working or not working ?
Also how many gpus did anyone tested on those motherboards ?

I am looking for 6GPU motherboard cheapest alternative and the MSI Z170 and Z270 are one my aim right now.
But i need to confirm if they are working with SMOS without problems ? (becasue i had reports that there was problems

This isn't true anymore, hashing with new kerner and driver gives exactly same result like windows.

No default settings is solving it, but I don't have any good news here I am facing this problem since January. It is not hardware related problem, it is something wrong with ubuntu or claymore eth miner. I have exactly the same, exchanged gpus, risers, slots, mixed cards, exchnaged MB, ram, PSU everything, gpus are crashing randomly. Also I have check ethOS, it is exactly the same. So it is not tytanick's fault anywhere. I was able to solved it partialy, it runs smoontly for weeks on windows machine (same configuration, same parts same everything), only windows instead of linux. Oh and yeee no bios , no straps working either. You can set default bios with default straps and  gpus will still hang on ubuntu. New drivers and kernel isn't solving this issue either.

give me a link to the pool I will try to figure out the issue
