- NO FEES - Donation Backed, We ask you donate 1 to 2% to help support our equipment costs
Nobody would be mad if you had 1% or 2% fees as long as you provide a ddos resistant high performance pool you are advertising. That hardware seems quite expensive to run on only donations. Regardless, good luck! Thanks for the input! We explain in our Why Donate page that we are trying the donation model to see how it goes, we ask users to donate 1%-2% if they want to donate more of course they can. If we find that users are just all turning off donations and not supporting us in large numbers then we will implement a 2% fee. We tell the users it's up to them how it goes  Trust me, no one will donate, just set your 2% fee now. |

The cynic part of me think BTC is there to sell AMD GPU.  naw, look at AMD stock, it's crash and burn. Believe it or not, mining is only tiny portion of AMD profits, plus most of the profit is earned by the manufacturers (msi, sapphire, gigabyte etc...). AMD makes shit margins on the chip. |

Ok, bought 12 sapphires, and 3 of everything else. Going to add another mobo and fixing asap. So I will start running 3 rigs with 4 cards each, and will thin them to 4 rigs ASAP.
Noob questions begin here.
1. How do I run the 4 gpus off the mobo listed? Can anyone provide a link to the required extra gear or cables needed. I did upgrade the psu to 1000's already btw
2. How do I clone the harddrives for mining?
3. I got long risers which will space the gpu's no less than 6" apart in a fan like set up, space is not a concern for me. Will this provide adequate cooling space for the 4 gpu on 1 mobo set up in the beginning?
Any tips and suggestions would be great.
Thanks!
iam not sure if 4x 7950 will work stable with a 1000psu. it will depend on the corevoltage of each card. i got 2x gigabyte7950, this version is overclocked out of the box with a locked corevoltage of 1,25. each card pulls about 320W, so 4x them would be too much for a 1000w psu Which gigabyte GPU? I'm running 4x gigabyte 7950 windforce, on a 1200W PSU with no problem, I didn't under-volt. They each only pull 200W barely, probably less. How can a 7950 pull 320W? I hope your 7950 better mine at 1000kh or something. Though you are right, 4x7950 on a 1000W most likely will not work, since PSU only work at 80% efficiency. So that 1000W is only capable of giving you 800W actual power, 4x7950 will eat that up, leaving nearly zero power for other components. |

Ya know what, FO. He/She is doing the best they can. Cut them a break. You get money for nothing and you expect millions! Get real and play the mining game.
If you were a real gold mier, you would dig a hole in the earth and expect return. Dig a hole in the cyber world and what you get is what you get. Buck up Pancho!
No, miners are not "getting money for nothing". Miners usually pay electricity cost and upfront hardware cost. Someone maybe mining at a slim margin, and can't afford to lose 25% of what they mined for weeks. This would actually put some miners in red, especially if they didn't profit at all from the double pay. |

notroll hot wallet is now on a first come first server basis, once it's empty, you'll have to wait. Try again after every new block solved by notroll.

Cool thread, thank you. I received 4x 7950s and four risers on Friday and the rest of the hardware won’t get delivered until tomorrow, so I used the weekend to raid my old hardware closet and put a miner together from scrap hardware. 4x Sapphire 7950 leftovers: Core i5 750 Asus P7P55D Premium (only 3 cards worked initially, had to do the PCI presence short on PCI-E slots 1+2 and cut the 16x extender on slot 1 down to 4x) 8GB RAM old SATA 2.5" laptop HDD PSU: Tagan 780W (2 cards + motherboard) and Enermax 570W Modu 87 (2 cards) and put everything in a square laundry basket somewhat similar to yours. The PSUs fit in there as well so the whole rig is extremely portable for what it is. The graphic cards kind of slot into the holes of the crate and lock in place unless you tilt them, so it is all quite solid even without screws. I’d say this rig is more portable than all of my desktop PCs I’ve had so far.    I put the machine in a tiny room heated to 32°C with an electric space heater over night to check if it would be stable at worst case summer temperatures and all GPUs hover around 75-76°C at 65% fanspeed. It’s super cool and quiet at normal temperatures. The laundry basket gives me around 2400 kH at 925/1250 1.000v (scrypt) or 2250 mH at 1150/1000 1.150v (SHA256). Now I can send the ordered Ivy Bridge Celeron + Z77A-G43 + RAM + PSU back for faster ROI (if I ever get to that point, which I doubt... but mainly did it for the fun of playing with hardware and funded it entirely by cashing out a part of my BTC). That laundry basket was a great idea, I now ditched my stupid green box for a shiny new laundy basket case. Now the rig is working perfectly, with the GPU hovering at sub 90C instead of 105C From now on, I will no longer buy computer cases, laundry basket is all i need. muahahahah |

I think even if some how you can't find out exactly who were double paid by what amount, you should be able to find out who mined during the period, AND what they were paid, correct?
Now if you just deduct these people's balance, by the amount they were overpaid, even making their balance negative, would have been fair, you have a record of their IP, yes? anyone who register on your site again with that IP just set their balance to the same negative amount. So either they never mine on your site again, or they will have to pay back. I doubt anyone will go through the trouble of avoiding your pool that they apparently liked to mine at, just for gaining a few LTC.
The action you have taken, deducting EVERYONE's balance by 25%, even those people that didn't mine during those two days, people that were trusting your pool to hold LTC for them. I believe this is morally the wrong thing to do, and is unfair. Now I understand using a pool as wallet is not very smart, but still it is wrong to take money from people that did no wrong.

Why were the profits so low this month? I looked at dooglus' chart of S.Dice's ongoing performance and it doesn't appear to account for a drop from ฿0.00012579 per share to ฿0.00000845 ... A reduction of .00011734! Almost 15x less.
My charts show the profit in February as 13333.24627993 and March as 1166.55910974. That's about 11 times more in Feb than in Mar: >>> 13333.24627993 / 1166.55910974 11.429550520506144 However if you subtract a fixed cost of 300 from each, it's a 15 times drop instead: >>> (13333.24627993 - 300) / (1166.55910974 - 300) 15.040227646836993 So that explains why the dividends were smaller in March. As for the 100 BTC per month fee for various staff, I expect contracts were signed before the price of BTC shot up. 100 BTC per month used to be a reasonable amount (and maybe will be again soon, the way things are going?) That's would be a stupid contract to sign, it should be a percentage of profit each month, say 2% or 3%. if BTC price shot up to $10000, SDice's entire monthly profit might just be 100 BTC. Also when the fee is tied to a percentage profit, it gives the consultant more incentive to do good work, as bad work will result in less fee. |

Sure, mtgox will support LTC and NMC, add a few thousand users, and what will happen to the server? They can barely support BTC without being down or lagging severely.
Why does everyone assume that is an non fixable and permanent issue? Those issue happened a few times, all after very very sharp increase of bitcoin activity. Let's FUD big time about shit that's easy to fix and of pretty low relevance (since they always get fixed) Tell that to the 18 minute trade lag on mtgox as of right now. My statement still stands as its exactly what I'm saying. A problem now does not warrant a problem later and is currently being fixed. Ok, so you think mtgox will add on a whole sets of other problem by introducing LTC, while the current problem is still festering? |

Before you flip out, let me explain this.
On 7/04/2013-8/04/2013 getwork miners were paid DOUBLE. Then since 14h ago EVERYONE was paid double.
Ofcourse i HAD to correct this.
This was also the reason the hot wallet dried up while i was away (and i still am, btw).
Did you reduce everyone's balance by the same percentage? because I only started mining at notroll last night, and probably didn't get double paid much. But I had a previous balance on the pool, that was fairly mined. I just wanted to understand the math on you did the balance reduction for everyone. |

yes way!
when BFL ships... 1btc = $999999999999999999999999999999999
OVER 9000
So, never? |

Does someone know how Asicminer is mining at btc guild? Here https://en.bitcoin.it/wiki/Comparison_of_mining_pools its said that Namecoins only are mined with getwork. Does this mean when using stratum Namecoins arent mined? The transaction fees are only shared when using PPLNS. So is Asicminer using it? And is the 3% the fee Asicminer has to pay or is there a special agreement maybe? Asicminer on BTC guild probably uses stratum, so no Namecoins. Yes, it is set on PPLNS ( https://www.btcguild.com//index.php?page=pplns&shift=4689 user 67117). I don't know about the fee, but it looks like it's automated, so 3%. Ok, so the transaction fees are shared too. I took a look, they arent very high yet, up to 1 Percent of the 25BTC per block sometimes but often way smaller. So they are smaller than i thought but good that its shared anyway... over time something will be collected through this. And mining namecoins... i wonder how rewarding this is. I checked the calculator and it seems that its not near the profitability of mining bitcoins. But i read that mining namecoins is an addition to mining bitcoins. It doesnt need extra power to do this. So it looks like extra money. So what does Asicminer lose if not mining namecoins? Or did i misread this? Edit: I found this thread: https://bitcointalk.org/index.php?topic=166213.msg1733270#msg1733270It implies that mining bitcoins with namecoins can give 13% more earnings. I wonder if thats true but if yes, then it would be a not small loss. Too bad that its not possible with stratum. ASICs CAN NOT mine namecoins because it is almost required that ASIC must mine with stratum, because they solve shares too fast. Namecoin can not be mined with stratum. |

.... But funny enough the rig with 4 cards is the more stable rig for some reason. I'm curious if that will change when I add another card to "balance" things out. Though technically it shouldn't make a difference, experience has definitely taught me otherwise!.....
Be careful MKEGuy ! I'm sure there's a good reason why it's not viable for a long term solution. Can the motherboard keep powering 4 cards like that without, eventually, burning out somewhere ? Taco we need your wisdom Yes... be careful... I have burnt 2 motherboards doing something like that back in bitcoin days. for 3x GPU, it might be fine, but for 4x... you are really upping your chance to burn the mobo. What 7950 cards do you have on there? It seems that diff cards pull diff watts from the pci-e slot. I've had problem getting 2x gigabyte to work together, but no issues with 2x HIS, and this is on the same mobo. That's true, I had two gigabyte mobo and two msi mobo, all runing 4X 5830, both gigabyte mobo burned in a month, and the two msi mobo still running like a champ after 2 years. These mobo were similarly priced. |

Can you make the login session a bit longer? everytime I go check stats, I'm have to login again. I'd like it to be at least 24 hour cookie. You can make it as a checkbox, so people like me who prefer to stay logged in can do so.

Well that green plastic box has a ...certain charme... I seriously doubt it's open enough to provide 4 7950's with enough cool air. What temperatures do you get after half an hour ?
As I understand it, one should aim to keep the temperature under 80 degrees c. Above 90 you are really starting to do damage.
My prototype runs up to 74c, and that's with only 2 7950's and no case at all.
Yeah you are right, the box is really bad for cooling, I couldn't run the 4 cards at max intensity, they would only stably work at intensity 13 on cgminer. |
