Deadsix did you try to use m2 to PCI to add 8th gpu ?
No, 8 cards do not work on Windows, only work on Linux. And I can not under-volt on linux, so my 1000W PSU can not handle 8 cards. |

Thanks so much for the advice. Could you give me some tips on creating an air funnel? Something I'm wondering if I could cover a rack in polystyrene foam, then attach a inline fan duct for intake and also for exhaust, maybe create a loop that intakes air from outdoors at the bottom of the rack, and exhausts hot air back outdoors at the top of the rack. I have no experience cooling things like this so no idea if this is even a workable idea lol.
This Idea is exactly how DC's have been doing it for decades  but its far too complicated to execute on a budget. Just create a simple tarp partition connecting the exhaust to the rear end of the machines, partitioning off the rest so that the air that gets exhausted out doesn't enter back into the garage. |

1070's at 50-65% TDP and overclocked core. Hunt for discounted aftermarket ones with good GPU and VRM cooling, and if available dual bearing fan ones, and GPU temp <75c and fan RPM <1250 RPM for longevity.
If you want to hit ROI fast, go with RX 470's, the cheapest you can find. The GTX 1070 is better once Ethereum goers to POS, but is waay more expensive so will always ROI later. Discounted 6-7 GPU mobo's (I have tried MSI Carbon Pro 1151 and it works fine with 7 gpu's, and it was quite discounted vs. Z270 models since it is older model). I could really use advice here though, really don't know what is most suitable.
MSI Carbon Pro is an excellent choice, stick to it, it is not recommended to go over 7 cards per system anyways. Cheapest Intel Celeron CPU underclocked that fits mobo.
Just get a G4400 Cheapest DDR3 or DDR4 RAM underclocked that fits mobo.
With that CPU/Mobo get Corsair Valueselect DDR4 4Gb EVGA P2 Supernova 1200W Platinum PSU's (I recently ordered Seasonic Prime 1200W Platinum PSU's but am a little worried about Johnny Guru complaining about the 18 AWG cables being unacceptably thin in some cases). Please let me know if Seasonic will be fine, I like the 12 year warranty.
Get the cheaper of the two, I have a couple of Seasonic 1250 GOLD's and they run perfectly fine. VER 006C PCIE USB 3.0 Risers. It's a little more expensive than VER 006, not sure if it is worth it, but price is good from Alibaba.
Either is fine really, it doesn't even matter. Ethernet Cables, router, and network switch I need advice on please I am thinking to start out with ~40 GPU's, then increase up to 72 (if 6 GPU per mobo) or 84 (if 7 GPU per mobo). I would really like to be able to remotely access each computer, and have them reset automatically if good electricity is available again. Get a cheap 16 port unmanaged switch. I am kind of hoping I can just do a filtered air intake fan and an air exhaust fan mounted to the wall, with the rack(s) in between the two with the racks enclosed so heat can be funneled out instead of leaching out into the garage. It is okay if the garage gets hot though, just wondering if enclosing the racks would be more effective.
Creating an air funnel - moving air regularly is the best way to cool mining rigs. Enclosed racks are a must for large number of rigs. Surveillance equipment:
Can use lots of advice here, will probably set up a system that streams remotely, will keep working with power cut, and be able to warn via phone+computer apps when anything happens.
Waste of money. Use claymore's mining monitoring sw or some of the other free alternatives, they will alert you over email when a system hangs. If you want complete hands free operations, check out Tytanik's Simple Rig Resetter device. |

I did a lot of research on stopping win 10 updates and I can keep them down to 1 or 2 a month at worst. but they fuck with virus settings and once in a while wipe stuff out. I did a lot of research to stop this from happening and most of the time it works.
Add the folder where you keep all your mining SW to Windows Defender exclusion list (in my case I keep desktop in exclusion). Problem solved. |

I am not sure why people are obsessing with Windows.
Get a single Linux CD (if you don't want to download) or usb and install on 50 machines..much higher uptime and NO idiotic restarts (granted, this is more of a Win 10 problem).
I do not know how/why so many people have such bad experiences on windows. The only time my windows rigs hanged or restarted was in the beginning when I was figuring out optimal settings. Since then all 10 of them have been almost flawlessly up for 8+ months, barring the occassional hardware failure. Almost all the advocates of Linus based OS'es like SMOS and ethOS etc DO NOT UNDER CLOCK/VOLT and just simply let the cards run at stock clocks/volts with cards consuming upto 40% more power for almost the same performance, and love it because they have to do very little. |

I installed uefi win10 with rufus. I can't get it too boot with above 4gb decoding enabled with 1 or more gpus plugged in (it will boot with it enabled using onboard gpu) any ideas?
I belive we solved it by skype. Also screenshot: https://drive.google.com/drive/folders/0B4y5D_zzH1oeZkhHenB5Tk8zeDA?usp=sharingFrom farm where we have multiple servers... All on MSI Z170A Gaming PRO carbon, all on MSI RX 480 8 GB and all 7 cards each. if any help is needet just skype me. cReepas Hey man, awesome setup, I believe thats 24 systems? You will be hitting 5GH with that soon Word of advice, please do not use the molex to sata connectors on your risers, 5 out of 10 short and burn. Please buy Sata powered risers (red colored), and use them along with molex powered risers. Remember - connect only 2 risers per cable. Best of luck |

Details about 10 GPU on ASUS PRIME Z270-P ETH - Total Speed: 291.283 Mh/s, Total Shares: 234, Rejected: 0, Time: 00:50 ETH: GPU0 28.438 Mh/s, GPU1 29.166 Mh/s, GPU2 28.939 Mh/s, GPU3 29.936 Mh/s, GPU4 28.957 Mh/s, GPU5 28.456 Mh/s, GPU6 29.877 Mh/s, GPU7 28.649 Mh/s, GPU8 29.526 1xSapphire 480 4G(Elpida) 7xGigabyte 480 4G(Hynix) 2xPowerColor 480 4G(Samsung) 4xPower 0.7kW link to photo  test rig - not nice view Great Job dude. Did you have to make any special changes in the BIOS? Or just plugging in 2 X 1-3PCIe Extenders worked? This is running SMOS correct? You are using 4 X 750 PSU's to make this work? Also from the clocks image, I find it very hard to believe that 1150/2150 is stable on a 4GB card with powerstage 1. |

Well, I suppose we must agree to disagree then! See, I believe that it's negative to freely share the best ideas, if they directly deteriorate earnings. It's a positive thing for the crypto community, to be 'secretive', to an extent. Otherwise, difficulty will be ruined too quickly; it is definitely a positive, and I appreciate the secrecy. I don't mind finding out the hard way, story of my life.
Are you confusing individuals being secretive with a community being secretive? As already stated, this community isn't secretive at all, infact all new innovation in software spreads like wildfire, and most do directly impact earnings. Do you happen to know which Linux tweaks those are, I'm kinda creating a huge searchable file of stuff to go through when I hit brick walls.
Well, seeing as you don't mind fining out the hard way ... |

There are folks running 9-10 card rigs, with undervolted cards, but you just don't hear about it nor see DIY threads because they have the difficulty in mind.
So if you don't see or hear about them, how do you know they exist? Did you dream them up? One has to assume that every successful setup isn't shared on the site. You don't agree? This community has been very open about sharing most of their trade secrets even, so I wouldn't agree. 8 card rigs exist, but only 2-3 people have the skills needed to make them, and even they have let the cat out of the bag on several occassions, you can run 8 cards on linux with minor tweaks. I have not, in my year and a half on these forums, heard of a 10 card rig, so its too well kept a secret to be possible. I did read that someone managed to get 10 cards detected in Linux a couple of days ago but that was a noob account and he hasnt shared any image or proof, so I do not trust that information yet. Some enterprising members like Jstenfanop are developing 8 card modules that can be added in pairs to run a total of 16 cards off of essentially one system, but that's specialized hardware, and its still in production. |

Can you share what motherboards works well with min 7 gpu rigs?
MSI Z97 GAMING 5 is recommended but what else?
Maybe somebody test them and can say if they work with 7 gpu:
- MSI Z97 GAMING 7
- MSI Z97-G45
- Gigabyte GA-Z97X-Gaming 3
- Gigabyte GA-Z97X-UD3H
...
Yes, just keep making duplicates of the EXACT SAME TOPIC over and over again, without bothering to read through the existing threads. Well done. |

Hmm the speed lowered and now its like before hmmm, keep looking at it gues, meaby its not good idea after all
u can include gnoil miner, they so fast   No Nvidia support dude. |

Im done with this snake-oil thread.
jstefanop Has not followed through with any promises of info.... which is the only reason I keep checking this thread for a honest answer.
Good troll my friend. PM me if anything real hits the table, till then, I am done reading this garbage.
Im sure theres many others in the same boat as I am.
Wow you are such an entitled jerk aren't you. He doesn't owe anyone anything, its not like he put it up for prebooking and now is failing to deliver. He has been pretty clear that its something in development, and you, while of no use to the community yourself, proceed to take a piss at him for trying. Filth like you hurts innovation and stinks up forums in general. Go crawl back into your hole and cry about it if you want, but dont bring it here. |

i'm using gigabyte am2+ and am3 old motherboard just about 25-30usd(not new) in here it have 5 pcie and i'm using 1 to 3 multiplier so all is 7 gpu and it's all work fine  ,all x4 procesor. i have asrock btc it just can boot with 7 gpu too,cannot boot if i add 8 gpu,no mather what procesor i put on it. i have asus rampage black edition too(expensive one),it just support i7 procesor,it has 6 pcie,using 1 to 3 multiplier it can boot 8gpu. biostar 990fxa am3 it have 4 pcie..i can add 2x 1 to 3 ..but it just can boot 7 too,cannot boot if i add 8. the most i can add gpu is in z170 asus(expensive too),if i'm using celeron it just can boot 7 gpu,if i'm using i7..i can add 2 of 1to3 multiplier and it's working all. so until now if i build new rig,i just using the gigabyte old one,it's very cheap hahaha This is brilliant news man. Thank you for testing it with all your motherboards. I would request everyone here to do the same, for the benefit of the community. Can you get 8 cards to work on the Asus Rampage? Are 8 cards mining using Claymores with that combination? For now, I can get 7 cards to work on Asrock H81 Pro BTC V2, and the Biostar TB85, but 8 GPU's do not work on either of these boards under windows. Will be testing them on linux with 8 GPU. Then will also test it on the MSI Gaming 5/7 for 8 cards, and the several Am2+ and Am3 boards I have and report back here. |

Hi Tytanik,
First off, love the unified dashboard that SMOS offers, and the ease of Rig management that it brings to the table.
I have been running SMOS on a USB 3 pendrive, on an Asrock Pro BTC V2 based system with 6 x RX 470 4GB cards.
Here are a few issues that stop me from adopting SMOS on all my machines :
1) SMOS hashes about 3.5% lower than windows for Ethereum Claymores 9.0
2) GPU0 is stuck on ~4mh/s no matter what
3) Rest of the GPU's also periodically drop to 4mh/s but then recover to their usual hash quickly
4) GPU fans spin up and down like crazy in SMOS, while windows had the fans gradually increasing/decreasing in speed
But I have kept a keep eye on your OS, and have a test machine on it always, so I do believe that I will shift all my rigs to it one day.
Thank you for making this wonderful OS and for keeping it free while you can address the issues/work out the bugs.

Currently, my rig has 750W PSU. With 3 cards running 100%, power draw at the wall is 590W. The cards I'm using are RX470 4GB, and in GPU-Z the power usage for each card shows as 95-105W while I'm mining.
I'm wondering if I'm able to add another GPU, increasing wattage by ~105W, making my rig run at ~695-700W on a 750W PSU? Is this trying to put too much load on the PSU? I know basic mathematics say it's ok, but I don't know enough about PSUs to know if it is reasonable of me to expect my PSU to be under 700W load 24/7. Thanks for the help!
As Phil said, if 3 cards are already at 590W for you, your cards are drawing 160W atleast. Adding another card would get the total to 750W, which may run but is not recommended at all. On a 750W PSU aim to consume no more than 600W in the long term. Now, I do have several 5 card rigs that have been running on Corsair 750W Gold PSU's for 8 months problem free, but all my cards are heavily undervolted/underclocked. Each card consumes 55-60W (GPUZ) and 100W at the wall producing 26mh/s. If you want to push your cards to 28-29mh/s though, a 750W PSU wont cut it, because power consumption goes up exponentially as you overclock. |

What I bought was this. Which pretty much doesn't do anything So you are saying I need something that comes with a big box like so?  Exactly - first version is without active IC chip. Second version should be OK. Second version also doesn't do jack shit for me. Just buy the Fit-PC EDID plugs from amazon, $9.5 is a good price. |

I'm not saying i would build an 8gpu rig i can buy six cards at $225 a pop mb and PSU and risers and thats only $1600-1700 or so , assuming i splurge on high end components. I'm getting free shipping so that 2400 price+shipping per panda is well over
the price even if i grabbed an extra 2 more cards to tack on to the next rig. I get longer warranties on actual cards and actual computer parts that have value, not this overpriced wana be asic.
I'm good on the panda madness.

Thanks Claymore, I didnt think perf improvement was possible for ETH anymore, but v9.0 give me a flat 2% Increase across all my RX 470 4GB Cards, now running at 26mh/s at just under 95W from the wall |
