Hey guys, I show u my rig.  Specs: Asrock FM2A55 PRO+ AMD A4-4000 G.Skill DDR3 1600 4GB 4x Sapphire 280x 1x Sapphire 7970 RM850 Nox Urano 850 VX550 Asus 990FX AMD A4-4000 Kingston DDR3 1333 2Gb 5x Sapphire 280x RM1000 TX750 Look good?  I am about to get a 6-card (sapphire R9 280x) rig put together this week, and right now am looking at about $3900 for all the parts (cards, risers, frame, corsair 1200i +850w PSUs, etc). Is this a good price, or should I be using a few lower-budget items? Trying to figure out what the $/kh ratio is that people are looking for when they build a GPU farm. also: is GPU mining going to be dead in 3 months when scrypt asics become the next big thing (gridseed is close, they just need to make a 40-chip board rather than the hokey 5-chip cylinders that cost more per khash)? or will there still be good profits in mining? I am just worried that I will put $400 into it, make $1000 [profit] in 2 months, ASICS will come out, and I will make another $1000 in the following 3 months, then by the end of 6 months GPU mining is obsolete and I am left with a rig that has little if any resale worth. |

I love all these rigs. Definitely have lots of ideas on how to build one for myself to go with my Bitcoin ASIC's.
Thanks

They are consuming about 1850 Watt and not 1650 Watt.
Also they are only running on about 1.4 - 1.5 Th/s and not 2 Th/s :/
O stop your whining. You aren't paying for the electricity so stop it. They are obviously setup at your work or somewhere. At least that's what I think? |

Even if he isn't paying for the electricity he is right to complain about the consumption.
Ever thought about the extra heat generated? There could also be environmental issues at stake.

all 10 Miner are online right now!
But I am not really happy with the result.
why are you so greedy? Its not greed.. these are very expensive and any loss of performance from what is advertised throws it off a lot. |

But each gives 720 kh / s to 730 kh / s
Maximum temperature is 78 degrees.
On our Sapphire R9 280X the maximum we would squeeze was around 730khs so I'd say your perf are in the average. Some manage more, but it really depends of the type of RAM you get (not all cards are born equal). 750/760 on the first OC run while I was setting them up for someone else. Due to lack of cooling that the person provided I did not push them further. Depends on the RAM used. On a card with Elpida RAM, ~720-730 is pretty much the max they'll go. On a 280x with Hynix memory, I've gotten >800khs/s. Most Hynix run in the 760-775kh/s range. |

If your 750w Consumption is true... I'm pretty jealous of your rig  |

You should build those to sell. That is one of the best setups I have seen in such a small, well place setup. Great job. - CPU: Celeron G1620 - Mobo : ASRock H61 PRO BTC - PSU: SuperFlower Leadex Platinum 1200W - RAM: 4GB - GPU: x5 MSI 270 Gaming (undervolted via bios flash (VBE7) to 1.063v) - USB Risers - OS: BAMT 1.3 - Total Power Consumption: 750W - Total Hash rate: 2.3 Mhs - Intensity: 18 / Thread Concurrency: 15508 / GPU-Engine: 1100 / GPU-Memclock: 1500 / GPU-Powertune: 0 / GPU-Fan: 40-80 Very happy with these results each card is getting 460Khs the fan never go above 40% with temps around 55C-65C so the rig is very 'quiet' and the x4 fans have a switch to lower RPM to improve this further. Overall power consumption is excellent each card is around 135W.      |

Very nice rig! I really like how small and clean your rig is. Did you build the chassis yourself? Is it made from aluminum? |
