Up! Power those eth rigs!

He posted here before the info on the motherboards and everything but the prices aren't that great for used motherboards.
Ah, I must have missed them. I think the prices are good considering that you get a CPU + ram with the motherboards. If you're willing to deal through here, appolo, I'd take the Z77A-GD65 and possibly the 7950. |

I'd buy some of your stuff through here. Don't know bitify nor do I trust them. Why post here if you're only selling over there?

Sweet, block #2!
Hit it with a Neptune and a 206G share.

Yes I agree. You should release this for free because its all about open source instead of trying to profit off newbies who can't install Linux on their own.
Then you can promote your website and you will get sales in return on your GPUs.
Newbies who can't install linux are not our target market. Big miners are willing to pay so that they can deploy faster. ethOS is relatively cheap to them, considering that without it, they would delay their deployment by days if not a week. In any case, I am not trying to profit off anyone. Our devs need to get paid, without money, they will not do any work. That's just how the world works. If you want free, download ubuntu and enjoy. I don't think anyone serious goes through an installation and configuration process every time they bring new gear online. I myself configured everything once, set that hard drive aside and clone it every time I bring a new rig online. Pretty sure anyone with common sense does the same. That being said, if there's a market for this that's ok. Up to people to decide what they want. All this "please give me things instead of making me pay for them" that is so common on this forum is downright embarrassing. |

Challenge for anyone - lookup how many blocks you've found for the pool you're on, vs how many coins you've earned. Prepare to be pissed.  |

hello , iam a small miner 18mh and its a bs to mine in a pool , most of the time the pool reads wrong hashrate from 18 to 8 or even 0 , sometimes i get 0.01 pre hour sometimes 0.02 sometimes 0.001 its just P***off tbh i would change to solo but it will take ages to find a block for me probably ,and i wont be able to know how far iam from finding a block ...
Your logic is flawed. It may take you ages to hit a block (or not) but it will also take you ages to earn 5 Eth. Switch to solo and be patient. |

Couldn't agree more. You're leaving a lot of money on the table by pool mining ethereum. It's just not meant to be pool mined, it doesn't work properly. I average 25% more per day than pool mining, and it's a hell of a lot more fun. A bit more work, but good things require more effort.
My friend was mining on supr for months, with 3x 7970. He has found 133 block for the pool, but only been paid out 430 coins. You do the math! I'm going to help him switch to solo this weekend.
My opinion is anyone with 50mh/s or more should solo mine. You won't earn less than pool mining, and all chances point to earning more. Hell, everyone should solo, no matter the hash rate. Eth just doesn't work on pools. Don't let the variance and time it takes to hit blocks scare you. It always works out.

I have a few Seasonic 1250w gold and an Antec 1300w platinum.

. So I will never see the 150 usd they owe me on batch 1.
What is this? The compensation for Batch 1 problems. They said they would properly compensate and they never did. Bitmain lies. All the time. Not surprising. I had to fight tooth and nail to get my promised S4 B1 PSU compensation. In the end, it wasn't even bitmain who compensated me, it was Yoshi directly from his own BTC wallet. |

I avoided the voltage adjustment based on the issues I've read about with the A6's. I find adjusting the supply while measuring the unit voltage yields the best performance. Though my experience is limited.
<snip>
-Optim
Do correct me if I'm wrong but if you are talking about remote sensing at the load these supplies can do that using the same pins called our for voltage adjustment, pins A1 and A2 so v drop across the PCIe leads can be compensated for by tacking a light gauge twisted pair to those pins and to one of the PCIe sockets where it joins the hashboard. Better yet - a separate pair coming from the board's input power planes to the remote sense in... The pic does label it as 'sense' and to me at least that means remote load sense vs v.adj. Just as with the HP DP1200 Commonn Slot Proliant supplies I have found it IMPOSSIBLE to get hold of a schematic for the power backplane these PSU's are used with. That would take all guesswork out of these. Prints for the various server boards or at the server boards backplane pinouts - no problem to find . grumble brumble. You are correct, though the result is similar. I have been adjusting with the trim pot internally, though I am planning to implement your Vsense cabling soon. That should give decent dynamic load performance; however, I have been on the fence about committing to the Vsense version. These switchers generally run a bit more efficiently (At the miner side, core voltage) when the input voltage is a bit higher. I have been adjusting the supplies using the aforementioned method under max load. In this case, I get a high +12V rail when the loads are less than 100%. I am hoping, this makes the miner slightly more efficiency. Yes. No one likes the internal circuitry known. IP and all. Maybe when one of these supplies fail, I will do some reverse engineering. Heh.  -Optim I can send you a failed DPS-1200-FB1 if you'd like to muck around with it. I've got about 9 of them. Maybe you can every point me in the right direction in regards to resurrecting them! |

The only 2000BB breakout boards I have are made by sidehack, and those work perfectly with the 2500BBs that I have. I'm 100% certain anything that works with the 2000BB will work on it's younger brother, the 2500BB. The pinouts are the same. The only question is, can the breakout boards handle the power? I know sidehack's overbuilt (I also love overbuilt stuff  ) boards can handle it no problem, and it looks like these would too. I'd be hesitant with the j4bber board if they're hitting 104c at full load on the 2000BBs. In fact, I probably wouldn't even use them up to 2000w if they're really hitting those temps. I ran j4bberwock dual 2000/4000 at 17 amps or 4080 watts for 24 to 48 hours multiple times. There is no way the breakboard I had was 104c or 220f Maybe 105 f to 115 f Not sure where the 104c temps are picked up from . That's not the board in question, not to mention 4080w AC is only ~ 3630w DC which isn't full load so not relevant. It would be nice to have that board tested as well, though. |

People will get burned buying gpus. Oh well. Just means gamers will get cheap upgrades again when the bubble pops.
In mining, if you aren't already equipped and ready when something interesting happens, forget it. You'll fall into a race to the bottom with the sweaty unwashed masses trying to get in.

Those are efficiency numbers for DPS2500BB, NOT DPS2000BB. Big difference, and the numbers can't be applied to the 2000w version. |

When the difficulty is rising fast, it is better to do solo mining. Hit more blocks while the difficulty is still low.

Ethereum shouldn't be pool mined. Solo mine instead. Even if you only have 1 GPU. You'll hit a block in about the same time it'll take you to earn 5 eth on a pool, probably even quicker actually.
with 17.8 hashrate how long it will take u think ? 8.6 days to find a block on average. http://etherscan.io/ether-mining-calculator |
