I found the following “franken” mining rig and thought it was a good example of a hardware altcoin miner made up of different kinds of graphic cards.
That’s a full 11 Gigabyte R9 270 Graphics Cards and 4 MSI R9 280X Graphics Cards in a mixed mining environment. The setup appears stable, running Windows 8.1, CGMiner & CGWatcher for auto-restarts should the miner hang for any reason. The rigs are broken out over a few wooden rig frames and in aggregate attain 8.2 MH/s while using about 3000w.
- 3 EVGA 1000w Gold Standard Power Supplies
- 2 EVGA 750w Gold Standard Power Supplies
The power draw of these rigs are always going to be a big drain on profits. For example, you can do 13 MH/s at around 1000w if you pick up a GAW Miners scrypt asic mining machine.
