I've been manufacturing an 8 GPU rig for a few months now, as a follow-on to 4 and 6 GPU open frame rigs I've been making for a few years... Initially this unit used Radeon 380s and now Radeon 470/480s. Some may have seen it listed on ebay, I sell some there but it's primarily for the exposure, most units are sold direct to large farm operators who are running 50+ units at a time. I do sell to individual miners as well and have been doing that for some time as well, posting this to share some details on the system as I have had a few people from the forums ask me about them... The units run a fully custom Linux load, or a customized version of ethOS depending on the end users coin, they can mine most anything as with any GPU rig, given how many GPUs are in the system I sometimes need to customize the miner or it's launcher so it runs properly. Prices start at $3600 USD for single systems and go down under $3,000 as the quantity goes up. ETH: 230Mh/s ZEC: 1200H/s Power Usage ~1150W on 220V+, 1250W On 110V These shots are from my 380 unit, 470 unit almost identical minus change in cards, and some strengthening of the chassis in my latest model revision to better handle shipping...    |

I worked on this firmware a few months ago and got it working, leveraging much of the experience I picked up building the original padrino firmware for the Jupiters. I ended up setting it aside as other projects started coming up..
in short this allows the KNC Jupiter Controllers (Beaglebone Black) to run KNC Titans, it also supports all variations of the KNC Jupiters as well, not at the same time due to how the FPGA controls the cubes, however you can boot with all KNC Jupiter (November/October), KNC Neptune, or all KNC Titan cubes without issue.
Since I am not going to have time to offer this to the community directly I am listing the firmware with source and build instructions, it has not been released anywhere else so the buyer(s) can do with it what they like, release it, or spin it into a paid offering like GenTarkin.
Given the value of the RPi bridge boards this looks to have some real value to the right audience..
Asking 6 BTC, my reputation on the forums is solid, however escrow is supported but only through a well respected and trusted agent that will verify the code themselves to ensure functionality before release.
The following is included:
- Working unified firmware and source for all KNC SHA/Scrypt miners for the Beaglebone
- 1 KNC Titan Cube
- 1 KNC Neptune Cube
- 8 KNC Beaglebone Controllers - Can make all Titan controllers, or whatever other KNC hardware.
- ~25 KNC November/October Jupiter Boards, no heatsinks (your call if you want them)

what distro and driver you use? atitweak does not work with 4XX series cards, you need to use the sysfs interface to make those changes, /sys/class/drm/card0/device/* google for pp_dpm_sclk for examples of how to use various parameters AMDGPU-PRO Driver with Ubuntu |

Submitted a pull request as well so it's ready to go. |

Is the lack of a Linux version due to a technical issue with your ability to pack the code or something to obfuscate? Logically the only reason the Linux version has been pulled is that was the version used to determine you copied some of mrb's code. Glad it was worked out between the two of you, but the reluctance to support it now moving forward is a bit confusing if all is well.

Unless you mod the bios to tighten up the memory timingyou won'5 be able to get over 30mhs on that card.. Have you done that yet, if not take a look at some of the other threads on the forums discussing it

I could not get the remote management to work.. tried.. http://192.168.1.3:3333 and https://192.168.1.3333 and it does not work. Port scanner shows the port open and active but the browser can not open the page just sits there spinning. Browser meaning a web browser or the remote management app? Unless something changed recently you need to see the application provided in the windows archive for remote management |

woow, does it support the dual mode?
Read the first post describing it |
|
|
|
Quite a bit more stable as well, not sure what it is about the silentarmy kernel but it's not as forgiving on the cards clock speeds as claymore's... |
|
|

@Claymore
is it possible to select the graphic cards which we want to use for mining ?
I want to use one of them for other coins. (Testing the other coin.)
It's in the instructions on the front page, -di if I recall correctly |
|
|
|
Is it true that Claymore made a powerful ZCash miner? Is there a link?
Look up like three posts and see for yourself. |

It could assuming it's still recognized as a device, when you say powers up fine I assume you mean the system sees a GPU like usual, just can't get the monitor output.. If that is the case it would mine fine.. Only way to know is to try it..

Yeah I think I got a fake Z payment as well nothing has appeard in my Z address in over 12 hours after the "PAYMENT" was sent
zcc2vMUsj46tJj8pE1ZaKZRH331zLqDaBMtaLhK27QUNviFFtJp24KZ67HrsQXzQEpSDfFPxrejLLDG sWXxksHBH4ZW7mK8
a fake payment of .39 was supposly sent then another one of .40 is now pending
basically nothing for 8 hours worth of mining yesteday
Based on what I am reading z payments are still broken due to a wallet bug.. It might be a while.. |

CPU usage is a kick in the teeth, G1840 running at 2.8GHz and I can't feed more than 3 AMD 470s before the CPU usage is completely maxed out..

Any word on general stratum support?
|
|
|
|

Bump, updated with items sold, a GPU and motherboards are left.
|
|
|

TY. Now since Newegg has them in stock with free shipping for $76.99, what's your lowest ask for this shipped to the Northeastern USA (CT)?
Has them in stock? I went liking again but cannot find them, what's the link? |

Posting some things I don't have any need for currently.. Payment in BTC/ETH or Paypal (for trusted members), all items shipping from the US, will ship internationally. Shipping is actual cost, generally FedEx Ground/Hoe Delivery or USPS is least expensive depending on location. (It's been asked a bunch of times, Yes they run 6 GPU just like the H81 BTC Pro) 63 - ASRock H97 Anniversary Motherboards - $75 USD each... All used for approximately one month before being pulled as I standardized all farm systems on the H81 Pro BTC. They do not come with the original box or manual/faceplate, they will be packaged in an ASRock H81 BTC Pro box for shipping purposes.NIB Sapphire RX 480 8GB $235 & 4GB Card $225 USD 3 - XFX RX 480 4GB Reference Cards (they are launch reference cards, should be capable of a flash to 8GB but I have not verified) - $225 USD & 1 XFX RX 480 DD Card $210 - Used for 8 hours of testing |

armyman your PSU isn't enough. You shouldn't run a PSU at more than 80% of it's rating. rx480's can pull up to about 225 watts each, which is 1,350 watts. You have up to another 150-200 watts for the system also, excluding the vid cards. So you are over 1500 watts on a 1200 watt PSU. Of course it will not be stable. A 1600 watt PSU will run 6 480's and the system....just. It is still pushing the limit a bit much when you factor in the 80% rule....but it will run stable.
The miner doesnt start - this isnt a problem by psu power. If psu power fails, the system shuts down. It is the PSU, during start up and DAG process the system draws more power. His ETH process is starting, but stops. Easy way to find out.....disable all the cards but one in the command line options, then enable them one at a time until the crashing starts again  I have tried as you said and it did work! Unfortunately I have just been able to modify the setup from my phone through remote control, but apparently with one card only it was starting mining....I have noticed that it the beginning the hashing speed was 0, is that normal? Yes that is normal, until the DAGs finish.. |

HOW YOU HAVE 11 GPU?!?!?!?
 LOL, one of the coolest things I have ever seen!   @Claymore: a max of 16 could be insufficient  Which exact model is that MB , and does it have additional power on PCI-E line ( similar to BTC -MBs ) That is not a motherboard, it is a PCIe expansion backplane that runs a little over $2K.. It does have discreet power but not enough to power all of the cards without powered risers. |
