CUDA and OpenCL rates are basically equal between a GTX970-980 and Radeon 290, power draw on GTX makes it the winner.

My R9 290X tri-x is doing 31Mh/s for around 180W (gpu@1150, hynix memory). A R9 290 with hynix memory and identical clock will do about the same. With some undervolting and no oc, you should be around 28Mh/s with 140W. http://www.mininghwcomparison.com/list/index.php?brand=amdNvidia is very good for others algo. I have mined spreadcoin with it but Ether is now amd territory (with the increased dag file, 750 ti is no longer as good as before). 3-4GB/card is plenty for the dag at the moment, and thanks to Genoil's work on the cuda implementation it's been a good combo. Each 970 draws 90w stock clock; but more importantly (which people seem to ignore) is *total* system draw is ~270W (core i5-based). A little o/c brings it to 300W, getting 38-40GH/s. Very profitable @ $2.50/eth currently! |

The problem with Ethereum mining is that it will become PoS within a year. If you want to buy graphics card for mining, you might not get your money back.
Profit-cost ratio (for me) is currently 5:1. Before Serenity comes, 'tis why you mine now and convert to other coin/fiat while it's worth something. To each their own, but what I'll still have is a damn good/cheap gaming box to enjoy that ASIC miners won't.  |

1. what coin you are currently mining
2. What is your your miner
3. What is the hash you are getting ?
Currently ETH using ethminer-cuda-0.9.41 on an EVGA SSC 3975 GTX970 (two when it arrives this afternoon  17.5MH/s with mild overclocking (110%, 1450 clock boost). Essentially the same hashrate as three 750ti's; so 3x50W vs 1x90W on dagger.... Previously ran FTC with ccminer-djm34-neoscrypt (CUDA 6.5 not 7.5) on same card, 700KH/s with O/C. Gave up on DASH/x11 though price is rising a little, used same as FTC, 8+MH/s. LTC/scrypt is ridiculous any more, but used cudaminer-2014-02-28 x64, I forget the hashrate.

If your electricity price is low, you can mine profitably on Ethereum. But if you have to buy GPU and PC system, you might not get return of investment. The Ethereum mining might last 10 more months and become PoS later.
Agreed — ETH is a/the hot commodity now, price has risen dramatically in the last month and makes it mildly profitable in the short term if you convert to fiat, but things can always go to pot quickly with any new altcoin. I do think ETH has a lot more technical legs under it than others, but others still persist and are rising too (DASH for example). To me, when you see kraken.com exchanging ETH directly to fiat already, there must be something to it. ETH mining rental service(s?) jacked the network hash rate up over 600GH of late, but you can still mine ~.7 ETH/day on a desktop with a low-power GTX970, based on current exchange rate @ $2.50/ETH (see my summary here: https://bitcointalk.org/index.php?topic=1275226.msg13725983#msg13725983 ). |

Just started mining eth this week, as price has risen nicely over the past month. What I've found, may help some folks here: Get the latest Ethereum Wallet from here: https://github.com/ethereum/mist/releases/tag/0.3.9Using the pre-compiled windows ethminer from: http://cryptomining-blog.com/5612-updated-ethminer-0-9-41-opencl-and-cuda-for-windows/CUDA and OpenCL rates are basically equal between a GTX970-980 and Radeon 290, power draw on GTX makes it the winner. 17.5MH per 970, 0.7 ETH/day. Also seems Win10 is (still) a dog on CUDA (don't think it applies to AMD/OpenCL), hash rates are a fraction because of paging issues. At 8-9 cents/kWH, after electricity and 1% PPLNS pool fee (coinotron), at $2.2-$2.5/ETH netting $35/month. Who knows what'll happen in a few months, but then again, what lasts forever... Good calculator pre-populated with current difficulty, block time and price: http://karldiab.com/EthereumMiningCalculator/convert ETH to $USD directly at https://www.kraken.com/chartsor ETH to BTC at https://poloniex.com/exchange#btc_ethIf anyone knows a better exchange please let me know -- fees on these may be somewhat of an issue... EDIT: A single 970 draws 90W (92W overclocked 110% @ 1440) ~74 degrees with low fan speed, overall system is drawing ~120W (core i5) on the UPS meter... Cool, quiet, efficient. |

-- a farm of 50-60 gtx cards
In the good old times [™] farms this size were quite common to mine Litecoin, even poor crowning had one. Ever wondered were all those GPUs live today? I meant brand-spanking new GTX 980's at $650/pop to reach that number, not 750ti's. My guess is it would take over 200 750's to do this?...  Who'd be nuts enough to do this @ DRK/USD $1.60? |

Not sure if this is appropriate here, don't know where else it should be (darkcointalk?)... x11 ASICs may not be around, but I just saw a single address hit 550-600MH/s (!) on an x11-only p2pool the other day. I've never seen this before, has anyone else? It still shows up in the hash graph, at least for another couple hours: http://p2drk.mupool.com/static/The fastest consumer GPU's I know of x11 do 10MH/s (GTX980 OC), so this equates to either: -- a farm of 50-60 gtx cards -- more than a few dozen Tesla K40 or 80's ($3-5K/pop) -- a cpu compute cluster of over a thousand cores of E5 series Intel Xeon's -- OR an ASIC developer finally got a test mule working Might be #3, someone having fun with another's toys... or am I nuts, is this now common to see? |

Both 960 and 970 seems to have some hardware problems right now, I was thinking of buying a few cards but will probably wait and see if they are fixed or have their price lowered.
I'm currently more interested in seeing if the 960 launch will lead to the 750 ti having its price lowered.
750 ti still seems like the card to beat for mining?
The "problems" with the 970 (I don't know about the 960, they were just released - too early to say) relate to "coil whine" afaik, and those are likely due to poor psu's or a myriad other things. Mine is quiet as a mouse, other than low whir from fans when hashing/intense gaming. My case fans make more noise... One 970 equals four 750ti's in x11 hashrate for 2/3 the power, albeit at a higher initial cost (a 960 = 2 750's). This is a density play - a 4x PCI board will equal 16 750's. In the long run a much better power solution as well. Interesting to see where this goes. |

Yes, cheapest 960's are Zotac or MSI, $200. EVGA's power-conscious 960 ACX2 model is $210. The EVGA 970 SSC ACX2 I have is $350 at Amazon.

Hi all, new to the forum. The 960 is probably not the best choice in the long run. Nominal power consumption only 20W less than a 970, but 40-50% less of everything else (currently available cards): — half the RAM — half the memory bandwidth/bus width — 1024 cores vs. 1664 (fewer SMM's) — 60% x11 hash rate of the 970 I strictly mine X11, and on a single 970 (EVGA SSC ACX2.0 known for its low power), it gets 7.7 MH/s with stock clocks and latest ccminer 1.5.3x. With ~8% OC, 8.4 MH/s. My entire system draws less than 160W running full-out. I think the equivalent Radeon R9 @~$350 produces one third of this hash rate (and uses more power). Add another 970, get 15 MH/s guesstimating ~250W. The same SSC ACX2 960's from EVGA would likely yield less than 10 MH/s for the same power. Be interested to hear comments. My box is a gaming system, just tinkering with mining for kicks. My day job is running a linux HPC cluster. |
