Title: [WTS] [UK] GPU Miners with VAT invoice (VAT can be reclaimed)
Post by: raidersan on January 26, 2017, 11:13:06 AM
I am looking to sell my GPU miners since I need to start being away from home in the future and will not be able to look after after them.
I am NOT looking to sell individual parts
I am based in Surrey, KT14

I am starting with 2 miners, both open air frames, GPU's mounted vertically. They are running EthOS for which the license will be transferred with the sale. EthOS is a Linux-based distro focused on Mining. it allows for central management, with regular one-click updates with the latest drivers and miners. As of 1.1.9 it supports ethminer, sgminer-gm, claymore, zcash-miner, optiminer-zcash, sgminer-gm-xmr, claymore-zcash and by extension can also mine Expanse. it also supports autotrading. More info here:

Of course ethOS could be substituted with Windows if required.
All my miners are plug and play. Plug in an ethernet cable, set your wallet address and select your pool. ethOS offers an externally available web interface to monitor your rigs for performance and temps and there is also an phone app to monitor all aspects of your rigs and get notified if something is amiss.
I will also give away the airframe 3D design so that more can be built easily.  

All my rigs below have been designed to max out the number of GPU's so they are 2 HD7990's for each miner amongst a mix of other AMD GPU's, maxing out the 8 GPUs limit of the driver. They also all use the great ultra stable MSI Gaming 5 motherboard, which ensure the miners are not plagued by the usual MB instability.

RIG 1: SOLD

RIG 2:

  • Double PSUs, 1850W total
  • 2 x HD 7990
  • 2 x HD 7970
  • 1 x R9 280
  • 1 x R9 280x
  • MSI Gaming 5 Motherboard with 7 PCI-e slots
  • 16GB Kingspec SSD
  • Celeron G1850 2.9Ghz
  • 8GB RAM

CAUTION: Following a BIOS update I have just lost one the GPU on one of the HD 7990, I am not sure if the GPU is recoverable. The performance and price will reflect this.

This miner gives 1712 H/s on ZEC for 1500 Watts at the wall and 95.4 Mh/s on ETH for 1275 Watts at the wall

RIG 3:

  • Double PSUs, 1850W total
  • 2 x HD 7990
  • 2 x R9 280
  • 1 x R9 390
  • 1 x R9380x
  • MSI Gaming 5 Motherboard with 7 PCI-e slots
  • 16GB Kingspec SSD
  • Celeron G1840 2.8Ghz
  • 4GB RAM

Perf: 1900 H/s on ZEC for 1650 Watts at the wall and 132 Mh/s on ETH for 1535 Watts at the wall



I am open to sensible offers. Those miners are plug and play and very stable, after spending months trying different components/OS/drivers and designs.  
I would prefer a pickup but I am happy to investigate shipping.

it all depends on how cool you keep them as I have them setup to auto fan to a certain temp. It can be fairly loud when the room is hot but they do get fairly quiet when I have my ventilation working (fan sucking). The 7990 are noisy compared to the others, that is for sure. The 7950 and 280 are most of the time very quiet

I'm interested and could pickup. Would you take £650 for rig 1?

My current highest offer is just above £1100

Na that's too high for me, could build the rigs cheaper. I'd be willing to look at around £800 but no higher. Let me know if the £1100 falls through.

I am selling these VAT included with a VAT invoice so if you have a business, you can reclaim 20% off the agreed sale price.
