 My latest build, I had to post it here  Assembled in VENEZUELA. Fantastic rig! What is the motherboard, GPUs and power supply? |

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

IMAGE My latest build, I had to post it here Assembled in VENEZUELA. Fantastic rig! What is the motherboard, GPUs and power supply? As @Kergekoin said, Lepa 1600 PSU, Saphire 280x dualx GPU (undervolted), but the mobo is actually a MSI Z77A-GD55. Running on Ubuntu 13.04. cheers! |

I'll have more anecdotes once I get the second rig cased over the weekend.
I'll be keeping an eye on this thread, I'll be interested to hear your findings.  Further observations over the last 12 hours or so lead me to suspect it's a combination of increased structural stability minimizing card-wobble, and lower ambient temperature that is allowing the gains. Was fairly solid overnight near 570GHs in cooler temperatures, and down to ~562-565GHs during the day now with ambient a few degrees warmer. I'd love to write it off as a placebo-effect, but I've tripped an OCD trigger, and it's game on now trying to unravel this performance curiosity. More tinkering over the weekend... |

G1000 Powering 4x 280x and 2x 23cm fans with ease. GPUs @ 1080/1500. 2.95Mhs total. The frame will be a closed case soon. Work in progress. https://i.imgur.com/oraQLaW.jpgHow are you powering 4 R9 280x cards with only a 1000W power supply? I can't even power 3 with 1000W, the rig crashes. I think they pull over 300W each, especially overclocked. Need to upgrade to a 1300W supply. |

How are you powering 4 R9 280x cards with only a 1000W power supply? I can't even power 3 with 1000W, the rig crashes. I think they pull over 300W each, especially overclocked. Need to upgrade to a 1300W supply. Easy. This is G1000. One of the best 1000W PSUs on the market. I can run 1200W power draw from the wall with no problems what so ever. This PSU can deliver solid 1000W to the cards plus additional for the rest of hardware. I ran my cards @ 1080/1500; 1.12v for a week and this miner took constant 1200W from the wall. Since cards ran little too hot in my warm room, i reduced the load a bit and now im running 1030/1500; 1.08v. Power draw from wall is now 1065W. This means that those 4x 280x draw about 900W from PSU, which is around 220W-225W each. 1065W and 2.85Mhs = 2.67Hs per Watt. Keep in mind that this is for whole PC. Cards efficency is around 225W and 715KHs = 3.17Hs per Watt. Not bad eh? |
