I too think this is a great idea and would be willing to start mining with the network if the phoenix patch makes it to an official release and on to the bamt stack. Also, is there anyway to streamline the setup of p2pool? The setup while not difficult, still makes me hesitate, which IMHO will keep others from coming on board.

Hi gigasvps,
Welcome to ABCPool !
From my testing of the pool, I was having about double the number of stales as arsbitcoin.com. |
|
|
|
Just came over with my previously created account. Let's see how it goes  Edit: This should put the pool over the 200Gh mark now. |

Awesome pool AnnihilaT. Really nice web interface and the pool is rock solid!

Is the irc channel now invite only?  |

I have 5 of these cases -> http://www.newegg.com/Product/Product.aspx?Item=N82E16811112318I no longer use them have have packaged them back up in their boxes with all of the parts. Would be willing to sell them for $35 a piece + shipping. Can be paid in $$$ or BTC. They are lightly used and a couple may have some scratches but they are great cases. |

I went to linux for stability but I find it to be less reliable than a windows box. Or is it just BAMT ?
The thigh is, if ONE gpu fail, ALL fail, and not even a power off will bring it back, on some board a reset will, on others only switching off AC will bring it back (if it does).
And can't do that remotely.
I never had a GPU problem on windows that a reboot(reset) would not fix.
I am running 15 boxes with BAMT without issue. Please lower your overclocks to find where they are stable. |

This is not a problem.
Bandwidth needs for mining are almost nil.
See zorinaq's blog, he has 4 5970 knocked into a single mobo via
x1 to x16 extenders.
The real concern when hooking lots of dual core boards in one mobo
is you're going to suck way too much current through the PCI-e bus
(beyond specs) and risk blowing/burning something up. Hence the
PCI-extenders with molex trick.
The extenders with the molex are absolutely necessary. You will also not be able to get *huge* overclocks with multiple cards. Plan for middle of the road. |

Is there a way to change my username within your website? I signed up a while back to get the 0% fee account and would like to come over and test it out but can't find a way to change the username.

My 5970s seem to be *much more* sensitive to ambient temperature than other cards like 5830s and 6950s. Needless to say, I have 4 cards out for replacement and have learned my lesson.  |

extra insulation will help retain more heat.
During the day, the sun is producing a pretty serious amount of heat within the warehouse since the sun shines a great deal here in FL. Installing the spray form insulation will allow me to only need to cool the heat that is produced from the equipment during the day and night which *should* help considerably. I have been reading about the spray foam insulations and they have a much greater effect on reducing conductive heat from ceilings even though they may have a smaller R value than traditional insulations. Installation is happening wednesday so I will soon be able to give some definitive results. I have monitoring equipment for the temps in the building so we will have before and after results with 19.5Gh running in the facility. |

Problem is, in Florida, you're going to have to do both. Condition the air AND exhaust the heat. Like this:  Except, since its only a 800 sq. ft. data center, instead of recirculating the hot air back into the CRAC you can draw fresh outside air into the CRAC intake and blast the hot air to the sky. Thanks for this diagram. Actually just had another hvac guy out and he was the most competent of all that have come out so far. This is pretty much the direction he is pushing. Smaller room, high air flow from one side of the room to the other and enough cooling capacity to cool the 17Kw of equipment (5 ton). |

I have been doing more work to rectify my "heat situation" and have consulted multiple hvac / ventilation specialists. The consensus seems to be to either vent the hot air out of the building or condition the air. Don't do both. Another point they kept bringing up is the very little amount of insulation between the roof and the air inside the building. So I am having extra insulation put on the ceiling early next week to see just how much it helps. I will be going for the highest R value I can get and will follow up once it is installed. Insulating 800sqft should be about a $1 a sqft, a lot cheaper than other solutions. |

If 800Sq ft the entire space or just the room the miners are in. If the miners are in a smaller space you could install a local (window or wall unit). Removing heat from the rest of house is inefficient is the heat is localized in one area.
I am in a warehouse that has an office within. The overall dimensions are 20ft x 40ft with 20ft high ceilings. The AC unit currently has two drops into the office and three blowing into the warehouse. BTW, I figured out the first things to do when it gets too hot, open up the 8x16 roll up door. Dropped the inside temp from 98 to 94 in a couple of minutes and it was free. Still need to figure this thing out though. |

Giga, your high ceilings are key. My shop is about 250 sq. ft. with 9 ft ceiling and poor insulation to the hot outside and the most I can pull is 12-13 GH/s with 24,000 btu ~= 3kw of cooling with refrigerated air. I am also exhausting the hot air through a 6" by 14" duct and a 1500 cfm fan. Insufficient and will be improved, but the electrical thing takes precedence and I'm still waiting for estimates from my electricians. If I had a 20 ft ceiling it would make a big difference. Just cut a hole in the wall at the top and put a 4500 cfm fan blowing all that hot air that collects out.
Should I also be piping fresh air in from the outside at the same rate? I have 20x20x40 space which is 16,000 cubic feet of air. Are you saying that I should remove a quarter of all the air in the building every minute? Also, do you have any links for prices on this equipment? |

Moved over from Slush because I got tired of seeing 5 and 10 million share blocks repeatedly. Looks like I made the top 30 - once I see how much stable it is I'll be happy to donate at least 0.5%. Just can't figure out why my stale rate is 3.5% using GUIMiner 8-24 OpenCL I would highly recommend using one of the following: cgminer -> https://bitcointalk.org/index.php?topic=28402.0phoenix -> https://bitcointalk.org/index.php?topic=6458.0I believe that you can use phoenix within GUIMiner. I haven't used windows for mining in a while since I started using BAMT. |

Evap cooling wont work in FL because your relative humidity is already very high. Evap coolers work by introducing cold water into the air through evaporation. If the air is already saturated with water, more water wont be absorbed easily. If your humidity is high and you run an evap cooler, you might as well just run a fan instead.
If it's dry in your warehouse, it still wont help much either. It'll be dry for a little while, but running an evap cooler will saturate the air quickly. You need a steady supply of dry air. My $600 cooler will crank through 5500 CFM of air. Circulate that around the building for 10 minutes and it'll be extremely humid in no time.
So based off of this information, my best bet is getting the hot air out of the building as quickly as possible and pulling in fresh air from outside. Something like this -> http://www.youtube.com/watch?v=G5f_e4P6gMA |

Hello everyone... I've got a second server set up now. If you want to help me test, you can set your miners to: server2.arsbitcoin.com There is currently no load balancing. Everything should work/look the same as if you were mining on the main server. There is a new stat on the right of the pool stats page that shows the total hashrate for each server. You might see lower stale rates on server2 because it has a lower load. server2 might also crash and burn and steal all your BTC  (thats my disclaimer). Also, server2.arsbitcoin.com accepts mining on port 80.I have been running on server2 for almost a day and am very pleased with the results. Stales are now below .2% for day. Amazing. Expect some BTC coming your way BurningToad. |

i dont understand how you only get 10 gh from 14 rigs
Look at my sig for details.
Run an intake and exhaust inline fan, this would involve cutting a 2X6inch holes in the walls leading outside. This will significantly lower your electricity bill and decrease the amount of a/c you would be required to use. PM for more details
I will be PMing shortly. Blech. If you weren't in FL, I'd suggest evap cooling. You don't really have another option in FL besides AC, I'd imagine.
Why do you suggest that this evap cooling would not work in FL? I am going to look into it now, but any further information would be greatly appreciated. EDIT: Also, it is very dry in my warehouse at the moment. Much dryer than anywhere else I go. Shouldn't I be keeping this environment at a certain humidity and couldn't an evap cooling system help with this? |
