I can tell you that my Gigabyte 280x gets a steady 730Kh/s and I have it undervolted to 1.075 and it stays around 73C, but I also bought mine for $300
can you please post the cgminer settings? --thread-concurrency 8921 --lookup-gap 2 --gpu-engine 1049 --gpu-memclock 1500 --gpu-powertune -20 -w 256 -I 13 -g 2 --gpu-vddc 1.075 --failover-only --gpu-fan 85 I am also using SGMiner, but I don't think it really makes a difference. SGMiner allows me to use -g 1,2 thank you zneww |

Nice steep curve on today's mining so far.
Here's hoping we hit the moon again.
Keep it up H20.
looks like h2o is stealing our coins again lol  |

your comparison is wrong. look at the first post of this thread. this ASIC is just a little bit energy efficient and generate just a little bit less heat than gpus. But the asic is two times expensive than gpus.
and remember, gpus have a second hand market.
The energy efficiency advantage isn't small— it's similar to the improvement early Bitcoin asics achieved over GPUs— and don't forget the secondary costs (PSUs, motherboards and slots, etc.) that these miners will reduce. The price is a product of the manufacturers pricing of an exclusive bleeding edge part— these are not chips which costs more to produce than GPUs by any means— even absent competition you can expect the pricing to eventually achieve whatever amount allows them to sell a metric boat load of them and the power efficiency will drive GPUs out of the market. This is my prediction at least. GPUs had their advantages but they did for Bitcoin too, the story is pretty similar and GPUs are irrelevant today for SHA256 mining. Agreed. but those chinese ASIC discussed in this thread are not evolved enough to replace gpus. in future ASICs will replce gpus. |

I think I will be waiting for dense Gridseed based hardware, but nice to see them in the wild at least.
For those defending GPUs as more profitable:
GPU:
Energy hungry
Hot
Hard to scale at a point without industrial cooling and power
Less up-front cost, but long term pain due to the above
ASIC
Energy efficient
Much less heat
Easier to scale (Simple USB hosts compared to also needing an entire PC to run multiple GPUs)
More up front cost, but savings in the long term due to the vastly increased efficiency.
Pluses and minuses as with all things. Anyone spouting off about how GPUs are so much superior are not considering all points.
I am looking forward for better Scrypt ASICs. But this ASIC will not replace GPUs. your comparison is wrong. look at the first post of this thread. this ASIC is just a little bit energy efficient and generate just a little bit less heat than gpus. But the asic is two times expensive than gpus. and remember, gpus have a second hand market. i'll be waiting for a better asic with less power and more mh. |

I am receiving this error on asia server. Anybody else having this issue
stratum_recv_line failed
...retry after 15 seconds
same here, just changed to the main server. |

if you don't see that you still get a significantly higher hash rate with GPU for the price of the ASIC Scrypt I don't know what to say.
Power usage savings of even 1k watts, is minimal considering the much higher hash output.
Do the math please, then really let it sink in.
I appreciate your condescension. Let me reciprocate it. The cost of the 3MH/s model is 11190 Chinese Yuan, or $1849.19 according to the supplier’s website. That is currently $0.61/kH Let’s just say you can get 280X’s left and right for $300 because you are a fucking wicked smooth barterer. You also get 800kH/s on each card because you are a configuration specialist. So just for the cards, you are paying $0.375/kH. Let’s not even factor in electricity or other components you need for your rig as we all have closets full of spare computer parts to build endless rigs. You are getting a 40% discount on hashing power with GPUs compared to an ASIC. Thankfully, you don’t have to worry about ASICs becoming more powerful and more affordable. That never happened with Bitcoin right? That’s why after ASICs came out last year, they were continually outperformed by GPUs. Oh what’s that? That shit didn’t happen? No fucking shit dumbass. If there is a chip that is producing 300kH/s right now, then there will be a Scrypt ASIC chip this year that will make GPU mining ineffective for Scrypt just as last year it became ineffective for SHA256. You can have this lesson for free. Next time you think your math is great, you should think a little more progressively and stop being short-sighted. 1. there's no scrypt chip producing 300kH/s 2. how much ram does sha256 mining need - almost 0 3. how much ram does scrypt mining need - shitload  4. is fast ram cheap? n0pe 5. can asic scrypt miners be as good as asic sha256 miners? (thousands time faster?) - N0PE , unless you can get 1000GB (ultra fast ddr5) cheap ram 6. can u stop telling bullshits? i guss so Scrypt ASIC may evolve in future. But the current one in the market is 2X expensive than GPUs and it consumes 66.67% power and emits 66.67% heat. The ASIC is little better in power and heat efficiency, but it is an expensive peace of crap from an unknown Chinese vendor, I will continue to buy GPUs until a reliable vendor come up with a better ASIC with considerably more hash rate and less energy consumption. GPUs + mobo+ ram + hd+ cpu + watercooling are still cheaper than that ASIC. In addition there is a 2nd hand market for pc components. |

GPU mining is NOT dead.
you can buy 9 R9 280X cards for $3500 and get the same hash rate 6MH @ 1800W. Power usage is higher than ASIC (1200W). But GPUs have a second hand market value. GPUs come with warranty and they are manufactured by well known companies unlike those ASIC vendors who accept BTC and Western Union payments only.

their power consumption is little better than four R9 280x gpus, but no resale value when the mining boom ended.
I've been wondering about this.... I mean, I assume we are all in this for the long run because we believe that cryptocoins have a future. If we are wrong and the coins go to zero... then yes, ASIC's and such will drop in value to 0. But let me ask you... given that we know there are probably hundreds of thousands of GPU's out there dedicated to just mining. If the value goes to zero and mining has no value... what will happen to those cards? People will dump them and they will flood the market... and granted the market for GPU's is much bigger but still relatively small. Your R9 290x will be going for 1/5th of what it is worth because EVERYONE will be dumping them. 1/5th is better than no 1/5th. Personally I think they would be worth more than that. lil 3MH ASIC costs $2700, you can buy 4 R9 280x for $1600 and get same 3MH @ 800W. There are more gpus in the market than those dedicated mining gpus and a gpu always has a value with or without a mining boom. mining will not end suddenly, either coin values will gradually decrease or difficulty will gradually increase throwing 3MH rigs out of mining. there won't be a considerable difference in 2nd hand market. this asic is not good for btc either. 50GH btc miner costs only $900 @ butterfly labs |

I don't understand why anyone would be interested in 10 GH/s BTC mining and only 300KH/s LTC mining. Even with the "big" 20x order you might as well get a Antminer and GPU's for less money and more reliability.
Now if they have a properly designed and cooled PCB with 20+ Scypt ASICs for a reasonable price, we're in business..
I'm mainly interested in it for the scrypt... not the sha. It is NOT easy to cool 3MH/s of Litecoin mining... not in your house. These are more power efficient then even GPU's so if you are strapped for space, power and cooling then they are a good option. their power consumption is little better than four R9 280x gpus, but no resale value when the mining boom ended. |

H2O steals our coins. Dont join this pool, mine elsewhere.

Not good for scrypt mining.
I have a rig with a 7990 and two R9 280X. less than $1900 for Gpus, but I get 3MH at 800W. the graphics card are more reliable and under warranty. I can sell them and recover a good part of the capital at any time.
butterflylabs products are cheaper and more reliable for BTC mining.

H20 SCAM ALERT!
People here to have to start realize they're wasting 15 GH/s hashpower every hour mining dust.
All I do is trying to make you understand that h20 is a scammer who is taking A HUGE part of your profits while he can't even maintenance the database. So now as a temporary solution he raised difficulty to 1024 instead of fixing SQL script. From my eyes it looks a like an amateur has coded it.
A 14-year old kid could do better.
-------------------------------------------------------------------------
I also would like you to know I'm still taking invitation requests for my invite-only pool. Price is currently at 0.02 BTC to help make sure profits stays high.
We are always mining the most profitable coins, which is about 2-3x higher payouts than middlecoin.
Let me know if you're interested. You dont wanna miss this offer.
H20 SCAM ALERT!
I love to leave middlecoin and join a pool with higher payouts. So far I wasn't able to find any pools that offer payouts higher than middlecoin. Even if he steels our coins his payouts are better than all other pools that I have tried so far. |
