WTH, I swear I read it as 200 GHash/s performance  20 ghash/s from ASIC seems low as hell. So the Rig Box would own this POS !? The Rig Box does 2.5 times more hashes, but at 10 times the electricity per hash. It comes down to what you value more, hash/$ performance or hash/watt performance. |

Each C200 mines at 20GHash/s, consuming a mere 100W. Designed for high density operation, the C200 provides efficient movement of air and is suitable for operating in a fully loaded 42U rack (up to 40 units per rack)...When compared with GPU mining, the C200 consumes 100 times less electricity and 14 times less rack space, meaning there's virtually no operating cost associated with this device.
200 Mhash per watt? If you can deliver the hardware at that spec, you will obliterate the competition. |

No but I live in the UK and have received confirmation of my order plus my money was taken over two weeks ago now.
Welcome to the club. |

Now what is the difference between 12100 BTU of cooling and 12100 BTU/h ?  I am simply trying to figure out what A/C I'd need for 1 Rig Box, 5 Rig Boxes or 10 Rig Boxes  (<-- this means I am not serious) I believe both of those are the same thing, but most leave out the per hour part. A good ratio I use is 3.4 BTUs per watt. The rig box would require at least 8500 BTUs. If your climate is particularly bad, go with a 10K unit. I have successfully cooled down 5,000 watts of electronics with an 18000 BTU A/C unit, with outside temperatures reaching 100 degrees. |

You forgot the last part of the calculation - divide by BTUs/kw. 4290 / 3413 = 1.26 kW.
Where are you getting those numbers in bold? For this particular unit the EER would be 9.6 (12100 BTU / 1260 watts), so not the best out there. Not sure where they get 2.82. |

I just looked at some air con models available here. 12,000 BTU, split and window type, around 1.05 to 1.2x kWh. I hope that's max and not some sort of average.
Pay close attention to the EER (Energy Efficiency Ratio). For window types, most don't go above 10.8 (divide the BTUs by the ratio to get watts used). The highest I've seen is 11.7 EER (1025 watts) |

Interesting. I'll have to do some more research on all of this. I also just realized the dimensions of the case they are using for the rig box contains an internal power supply. Try to imagine a 2500Watt power supply. It definitely couldn't fit in there. Even two of those 1500 Watt monsters from Newegg would not be enough (80% efficiency, so only 2400 Watt) and two would physically already be bigger than the "Rig Box". The ratings on a power supply is the amount of watts it can deliver to the components, so two 1500 watt PSUs would be enough. Regarding heat, I ran 1,500 watts of GPUs and it easily overpowered the room they were in, even with the central A/C that was running around the clock. I agree with SgtSpike, you will absolutely need A/C to cool down 2,500 watts. |

This comment is oddly prophetic. I'm going to pitch a different take than a few others: Yes, great initiative, please keep trying things and building things, but end this project now. There are no probable outcomes where you do not end up having to explain where thousands of dollars of other people's money went to some angry people. I do wonder how an 18 year old is going to come up with $200,000 worth of bitcoins as reimbursement. I don't know how profitable bitcoinica has been, but that much money seems too much to overcome. |

3 or 4 weeks ago, and you were the direct inspiration for it.
I'm very happy to see the design replicated!  I kept thinking how almost every detail was spot on, it would have been a huge coincidence if you never saw my rigs. Why is that vortex fan green? As far as I know the company only makes them in gray. Then both of you need to clean up your rigs. Sheesh.  Okay, I don't know about Brian's, but what is going on in that picture? There are fans blowing at the *exhaust* side of quite a few cards! The fans are just fighting each other.. I actually thought a lot about this. Just through touch I could feel that each end of the card was exhausting heat, even more so for the power cable side (away from the interface). I, like you, always thought of the interface side to be the exhaust side. I even took a smoke machine and introduced some smoke at the fan intake to see where it went. It was about an equal distribution to both sides. Couple that with the fact that I wanted access to the interface side, along with the USB and other components on the motherboard, I decided to suck the heat away from the motherboard/gpu interface. From the photos, you can see that I sandwiched the GPUs as closely as I could. I did this to maximize the airflow across the GPUs and increase the rate at which fresh air was introduced to the fans. This is what halfway clean rigs look like. Pink rope is a requirement:
Your setup looks very clean, but doesn't deal with exhaust heat at all. Isepick and I are down south and heat will become a major problem in a few short months. You also use many fans. I think using one big powerful fan to deal with all the heat is the way to go. Now back to our regularly scheduled thread topic.
Starting now. |

I had considered going under water for my 10 Ghash/s, but since I have none of the blocks or rads, it was going to be way too expensive. Instead I went the ghetto route:   That's a 12", 1000 cfm vortex fan (pulling 350w). It is far cheaper and easier to suck the hot air outside. The whole thing (rack, fans, foamboard, tape, etc) took $500 and a weekend to build. I live in S. Florida and this is my solution for the summer. It used to get over 100F in that room with only 4 rigs, now it is maybe 5 degrees warmer than the rest of the house on a hot day with 7 rigs. This may or may not help you, and watercooling is a hell of a lot neater, but from a maximum profit point of view it is cheaper to move a large quantity of air over those cards than it is to water cool them. And yes, that fan is louder than anything any video card . Anyhow, just throwing this out there for ideas. Good luck. When did you build this? It looks unbelievably similar to mine. |

why are bitcointalk and mtgox hosted on the same server anyway?
They are hosting it for free. |

You should just send your rigs to someone with 2 cents per KW/h rates.
This being where? |

The large pools make a lot, but when the price falls sharply their margins become very thin. The smaller pools are pushed into the red and miners, who are then making a lot less, try to maximize their profits but migrating to no fee pools.

You don't have enough money in your account for a succesful payout (account holds BTC -2.29770277526). - What is this?
Only a few posts up... There were several transactions that were registered incorrectly. After checking that the transactions were indeed included in the blockchain we have corrected the balances of the corresponding users, rounding in their favor. Additionally, we gave the user that reported the issue a reward for his acuity. For those affected, be aware that corrected balances are likely to be below zero, since in effect we pre-payed for your work.
Sorry for the inconvenience!
Happy hashing everyone,
MC

I am glad I got out when I did then.
Do you have anywhere else to troll today? |

No, you're taking the quote out of context by removing important details (such as relevant quotes). Though, admittingly, I misread your statement about BIP 16/17 support. Regardless, I agree with inaba. There isn't anything inherently wrong with redirecting the hashing power somewhere else from time to time. They never lied about it or explicitly stated they were mining the blocks themselves, nor have they admitted to pool hopping (the practice of mining for a pool at the start of a new block, in case you didn't know). This is why post count is important.
Honestly, how old are you? |

My complaints prior were about reliability which was 100% accurate. I am just reading about them not mining their own blocks today. It was confirmed by goat. I have been teetering on the edge of leaving ABCPool for some time but this is the final straw for me.
Can someone explain to me how someone becomes VIP with 100 posts?
You complained that ABC pool couldn't defend against a DDoS, which no centralized pool in existence today is able to do. Is post count significant to you? |
|
|

Combine this with me not supporting BIP16/17 until further testing and it looks like I will be going back to deepbit.
Tycho is taking the exact same approach. With your constant complaints (which are inaccurate) you hurl at ABC pool, I'm surprised you haven't left long ago. |

I always appreciate seeing your posts absent of absolutes. You know you have the best solution only when you can pick apart the flaws it contains.
