After 2 months of posting this, the 280X still seems like a much better alternative to the S7, even though the S7 is about $500 now instead of $800.
The 280X makes only 70% from what it made back in Feb 10th, so I guess after the huge pump and huge difficulty increase, its still pretty impressive.
The thing that scares me is people chase profit who make asic chips. There were X11's being ran that we did not know about when the asics were made, due to keeping them private. Now you can buy an asic that does X11 due to them being used and they already made money back selling is just a bonus. I think if ETH remains profitable you can count on someone trying to make asic chips for it. How long it takes.. and if it remains private we will not know. But I hate that possibility of dropping money on GPU and an asic can come out and blow it away. It should be Okay, ETH is planned to go to PoS SoonTM. If you care for the value of Eth anyways. For continuing mining, though, tough luck. But thats where GPUs shine. I am now running 150 mh How long before we go to pos. I guess in several months we might know better. Not before Q4 is my guess. So long enough that you dont need to worry about it at current profitability. But soon enough that ASICs probably won't hit. Also the cost of making ASIC using a DAG would probably be expensive, and doing it without a DAG would probably mean very very low performance. So i'm not worried. Worse case scenario, Switch GPU to something else. ETH is no longer the "drop everything and mine that" currency. It's still good but private miners do better, now. |

+4.2 = VirosaGITS
I'm thinking this may be too low of a pick.

can any please tell me that how are these gonna work? and what kind of post could be posted on these? please explain ?
Are you asking what the subforums are for? Meta is to talk about the forum, this is where this thread would belong. Mining support is support for mining Bitcoin, not to be used in case of any Altcoins. Technical Support is for more technical/advanced topics, like backend stuff the typical user has no hand in. |

Private Key Dump/Import GuideDump (extract)1. Run HOdlcoin-QT (open the wallet) 2. Select Help 3. Select Debug Window 4. Select Console 5. If you encrypted your wallet, unlock it by Typing: walletpassphrase "YourLongPassphrase" 600 (walletpassphrase <passphrase> <timeout>) 6. Type: dumpprivkey <your HOdlcoin address here> 7. This will return the private key, you can copy it now; ensure you clear your clipboard/history afterwards 8. Type: walletlock Example: dumpprivkey HodlDsNuts57MFNiN8CMrMjC2CYAy8pwi9 Import1. Run HOdlcoin-QT (open the wallet) 2. Select Help 3. Select Debug Window 4. Select Console 5. If you encrypted your wallet, unlock it by Typing: walletpassphrase "YourLongPassphrase" 600 (walletpassphrase <passphrase> <timeout>) 6. Type: importprivkey <hodlcoinprivkey> 7. Type: walletlock Example: importprivkey 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS This is for the newcomers to Crypto.. Dump doesn't remove this key from the wallet.dat file.. it simply gives it to you.. when taking it from one wallet to another.. both wallets will be able to access funds in this address... there is no problem with that.. I just wanted to clear it up.. Newbies should not be going around exposing their privkey in the first place. The second thats done, the security of that address should be doubted and thus should never be used again. |

Lower it
Is there a reason to do this? I run mine pretty hot on silent PC fans. |

It was good already having some 280x and buying some 7950/280x or such at 140~, but now i been buying strictly retail low TDP cards, with better W/MH than Nvidia and r9 2XX AND much much better MH/$ than Nvidia, though not as good as used GPUs (i guess, but who knows people are still buying like crazy even when retail would be betteR). I'm disappointed that Nvidia have no place in Ethereum, the prices of 970 just doesnt meet the performance. But once you move away from Eth, maybe you can go to a coin that is OpenCUDA friendly? |

This would be great news only if someone would've made or would make a breakout board for it.
Considering there's cheaper, bigger, better PSU, i don't really see them making one for these. Also the availability of these is not very clear and the price would need to be like 20$ per unit. |

The consumption of S7 is exactly 1202.50 Watt.
If the efficiency of PSU is 0.93 then we get 1293 Watt.
Its really not. Its more 1300w DC. I got 135 Chip # units doing 1375w at the wall, and units doing 1430w at the wall. If you want better efficiency, you're gonna have to get used high chip count S7. |

OK you seem to have ignored my previous two posts so here's my final advice.....
You are way too late to get into Mining, even with your pretend free electricity. After buying the miners, and PSU, setting up the operation with suitable racking, cooling and safety systems, you then have running, maintenance and replacement costs to factor in. The life of the Miners will be less than 5 Years, maybe as short as 3 Years.
So here's what to do. Take the £20K and buy a sign that says Bitcoin Mining and stick it on a Door, spend the rest of the Money buying Bitcoin. A lot less hassle and far more likely to be profitable.
Rich
Hi Rich, I did read both of your posts and thats not exactly what you said if you care to scroll back up? You talk about getting discount vouchers to buy miners.. at no point have you said anything of the such about being too late to mine. We know we are late comers to the mining industry but as the saying goes better late than never... https://bitcointalk.org/index.php?topic=1436810.msg14542267#msg14542267Also our project is to mine and make some coins for another project down the line.. while there is still 5 million + coins to mine I can't see how we are "too late". I thought with bitcoin the more people mining was of great benefit to the network.. I don't see the point in buying 20k of bitcoin when we can help support the network and earn coins back over time. We are hoping in time the director of the company will possibly invest into the mine with us, he has already been very generous by gifting us the space and the access to his power. and I am sure he will be more than willing to possibly buy new technology in future when it becomes available.. I know you say well the miners have deeper pockets than us that is correct. But as we prove to our host that we can 1. run a farm successfully 2. run a farm safely 3. generate coins.. then in time I am sure he will open his wallet and invest in better technology with us.. I must stress this guy was in the Sunday times rich list 5 years in a row now and has very deep pockets. But to prove a point before asking for investment he has given us this opportunity to do this and it would be foolish not to take full advantage of whats been layed out before us... thanks Well go ahead, but mining doesnt really support the blockchain. If you want to do that, do your mining if you want to, but be sure to setup a full node somewhere else. Unless you're talking in PH/s, it will provide no support whatsoever and if you do talk in PH/s, its still pretty marginal considering China already has majority. At this point the only thing that would help is for them to decentralize their hash. |

Now onto my next question. Were in the UK are reputable sellers of miners? or is this going to be a shipping job for outside the UK?
There are so many sites advertising them knowing which ones are reputable is a bit of a stab in the dark,
The only manufacturers are Bitmain, Avalon and Bitfury atm. Maybe Spoondoolies. Regardless its all imported. You say they just want a small portion of the coins. I'm not sure they realize it would cost 1$ of electricity for every 1.2$ over 3 months? Meaning unless they produce power and their only concern is selling it. Not buying electricity (unless they pay less than a cent per kWh), is less loss than selling you electricity for nothing. IF you/they dont care. Head to Bitmain and order S7's. There company is a Multi-Million pound turnover and we have been told not to worry about the electrical cost of the farm but to try scale it up before the next halving in 88 days. If we can be up and running with 70TH/s for the next 88 days to see how things go before the halve, Also we are thinking that as we move towards the last 5 million btc left to mine, I'm sure that some of the bigger farms will suffer and go offline with the costs they are spending on electric, Surly a split for 25 btc to 12 will hurt the bigger players more than the small time miner operations. I noticed as well that if say a big miner site goes offline and the network starts to struggle the difficulty will re-adjust automatically, so its makes it that bit easier for the farms to come back on line and move into profit again.. I take it this means that block times will start to fall the closer we get to the end of the road.. even thought that is theoretically not instill 2041, I Think this will be where the smaller farms come back to make there money. Hmm. 70Th/s is minuscule (vs network). If they have money coming out of their ears, sure. Thats not a whole lot of electricity. Tho i'm pretty sure in the UK they would earn much more if they sold the electricity rather than (you) mined. But lets move on. So you know about the halving, so you know anything you buy atm will be even less profitable in 3 months. We also know that for private use, there's like 0.1 efficiency chips that won't be out until... oh look, just before the halving, to dump on idiots. Okay anyways. When the halving happen, it does not really matter as far as "hashrate will drop". Sure it will do something, but actually, big farms have a huge advantage over you and small miners. First they can secure mW's of electricity at dirt cheap (like 1-2 cent/kWh) and second, they get the better stuff before you, and they get better prices. You can do your math and calculate free electricity and do ROI based on that, but i really much doubt they would be willing to supply you 1mW of electricity for free. (Ofc thats the the case for you yet) So you can get some S7's or wait after the halving (smarter, because S7's value with basically drop overnight to crap). As far As Bitcoin go, its not a pretty scene, but if you can have someone else shoulder the bill. Go ahead. You'd only need like a dozen of S7, or so for your goal. You won't earn much money and i'm pretty sure they will lose more on electricity than you will earn, but who cares, its not your money. ;P |

Scrypt is ASIC territory now. Do Ethereum.
Also head to Altcoin section, not Bitcoin section. You can come by the IRC in my sig if you want more info.

You will probably need to rewire and split to make PCI-e ends. Or you could jury rig the +V to the +V on the connectors. It would work but its not something i would do. Maybe you could find some kind of breakout board that you could connect all the + to one bolt and all the ground to the other and then connect PCI-e cables on it.
thanks. I found this kit: http://www.amazon.com/Gigampz-Adapter-Bitcoin-Antminer-ASICMiner/dp/B00OPDU6FWbut this is expensive. I think the best solution as you mentioned is rewire the psu. Pretty sure thats a breakout board for a different PSU. I dont see how you could make this work with the one you have. Oh. I thought this is universal kit and i can use it for my psu. Yeah its definitively not. Its for the DSP-800 as per title name. |

My eyes went O.O. I don't recall seeing such high temps either. IIRC there were good Neptunes and some bad replacement batch. Some chips are designed to run hot but, that seem a bit extreme.

My advice is to go to their threads and ask. https://bitcointalk.org/index.php?topic=167229.0From what I've read it may be CUDAminer the one with sha256 support, but that's the nvidia community, they can give you better advices. Aa others said, sha256 mining is not worth to be done on GPU. Power consumption is too big and you compete with ASICs. More precisely. You can't compete with ASICs, so you're wasting your GPU for no gain. |

Does someone have a link to the hardware comparison spreadsheet? I can't find it in my history/bookmark somehow.
I'm debating getting a i7 over a i5 if i can recoup the cost.
I can give you my stats for cpuminer-opt, similar to hodlminer-wolf. i7-6700K @ 4 GHz, 8 threads, 260 H/s. i5-2400 @ 3.1 GHz, 4 threads, 180 H/s. Thanks. If someone has data for i5-6600K to compare to the 6700K that would be dope. |
