I've submitted a pull request with a 2-3% speedup in decred.
I may work on it more, if there is interest.
wow: in a world of private miners, I push a free speedup to a popular algo and don't even get considered... so far for my opensource miner efforts. It's a thankless job. I've been busy with cpuminer-opt and mining has been in the background. But have started to take a look at decred. Don't take it too hard, I'm sure we leeches will suck up every bit of free hash we can get. You know I wasn't talking about you neither tpruvot, both of you are making an awesome job and sharing. And I shouldn't be wining once again about how thankless is this community....I already know indeed. Or maybe I just wanted to post something to reach that nice legendary badge ;-) Hello, I am mining eth with amd card, no longer having nvidia cards but I appreciate your work : maybe in the future, I will switch back again to nvidia and mine decred and benefit from your work. |

Wait a second, for decred donators decred #5 costs an additional 0.1 BTC?
It includes the optimized V-cash kernal. 13% faster One of my buyers have spread #4 all over the internet. cause you are a asshole sir. you should prob stop selling stuff cause i will give out everything you make until you lose ur asshole ways. ... All this just for some bug in hashrate for one of the private release? You are really in hurry to judge sp_. I have used private ccminers for spreadcoin from sp and was happy with these : If I remember correctly one of the release had some bugs too. For me this is somewhat normal (zero-bug software are really rare afterall) as long as sp is actively fixing the bugs. I didn't bought decred ccminer (I have R9 290X mining eth now), but with giving away this ccminer you are punishing other people who have bought this miner. |

Could you please post gpu-z screenshot from Fury (Nano) mining etherium? Is there a memory controller load data?
How do you think what is the reason why Fury cannot beat Hawaii in ETH mining?
From the results, non oc fury beats non oc hawaï and oc fury is just a little bit better than oc hawaï but at a lower power. Beside pure compute performance, one key point is memory latency access in eth mining + some memory cache: hbm is very good for bandwith but not so much for latency. On nvidia side, a GTX 970 is almost as good as a GTX 980 Ti probably due to issue with memory cache or latency... |

if you think that ethereum is still the most profitable you're doing it wrong, there are better alternative, i'm making almost $7 per card with another coin, i won't tell you which one is for obvious reasons
A R9 290X oc will bring around the same with eth. The advantage is I don't have to worry about changing coin mined every day/week : the revenue is consistent/increasing since december.. If the decline of eth price continue, maybe I will switch to decree or an other one. |

Have you considered they might be running custom kernels?
I have yes. Knowing a few devs here, i'm pretty sure there isn't an optimized kernel out there that does those kind of speeds  But if it was true. They should mention it. Greetings Benchmarking eth mining is tricky : if you use the built in benchmark, it will use the initial dag which will leads to higher scores for most cards. Moreover, you will have some significant variances between the differents runs: the builtin bench will give the max/mean/min, but I suppose some people have given the max instead of the mean.

It's hard to say really. I never really tried to understand much about Ethereum, because it doesn't really sound like it's a "currency", rather, it's sort of a "database" system prototype. I'm pretty sure Microsoft bought out Ethereum as a testing ground for their Azure platform. So, in a way, I'm just not that interested in Ethereum. I don't want to sound like some kind of shill for an altcoin on here, because I hate when people use FUD to encourage people to buy some of their coin. But, I personally think the new coin on the block that holds a legitimate value compared to bitcoin would be Monero (XMR). They are sort of a fork off of DASH, in which they both use the "cryptonote" code. If you don't know much about the cryptonote system, it's basically a way to anonymize transactions on the blockchain through "ring signatures". Monero is different because of a group of active devs working together on the codebase... whereas DASH has become sort of stagnant with active development. DASH is also pretty well known for being insta/ninjamined at the beginning, so that the very early adopters have an incredible amount of coins under their belt... Monero was a fairly launched coin, which makes it more appealing to other people who weren't the very first people to hear about it. If you want to read more about cryptonotes... here's the white paper: https://cryptonote.org/whitepaper.pdfAlso, here's what's being worked on Monero as of right now; which is Ring CT (way of anonymizing the actual amounts on the block chain) this is being worked on by Shen-Noether... someone in the monero research lab: http://diyhpl.us/~bryan/papers2/bitcoin/Ring%20CT%20for%20Monero.pdfAgain, I really don't care if you guys get into it... I just really like it to help remain anonymous in my transactions, and not have everything publicly available on the blockchain. A cool tool I use, primarily for buying stuff in BTC, is using my XMR (monero) and using https://xmr.to/ to pay any vendor who accepts bitcoins, and pay with xmr to help remain anonymous. It just converts how much XMR is worth at the current moment of purchase (in BTC) and pays the vendor in BTC. Edit: I will have to say though, that it does propose fixes for a couple of the problems that Bitcoin is facing right now... 1) XMR has adaptive blocksizes to adjust accordingly to amount of transactions being done 2) Tail emission features, where the total amount of XMR is added on to in the future to incentivize mining in the future (should be 18 Million coins, and then keeps adding coins as need... where it will get closer and closer to 21 Million over time, but keeps decreasing rewards so it never really gets there). very interesting post,this is the kind of post that will educate newbies like me on what to look for on any crypto currency,newbies and seasoned holders should read this post before they hype on useless coins It's also dead wrong. As a matter of fact, XMR is not a fork from dash but from BCN, the first cryptonote coin which have probably been ninjamined/instantmined... Dash and XMR are both targetting privacy niche but they are very different. |

By the way 7970 is the same card as the 280x.
Yes, in general the 280X is clocked higher, but if you overclock they have the same hashrate (with same memory and good bios)... |
|
|
|
Yup...now I don't know whether to dump my DASH or continue holding on to them  History dictates ... dump... I just don't know. You may dump half of your bag and keep the rest : you won't loose too much but you will not fully win either. |

AMD 7970 - +-18 MH/s - Eth mining
AMD 280x - +- 25 MH/s - Eth mining
AMD 380x - +- 27 MH/s - Eth mining My 7970 ( 1000 \ 1500 ) ~ 22 Mh\s Hashrate on ethereum depends on memory timings which varies according brands and bios. generally Hynix memory is better than elpida. Moreover, hashrate of 7970 and 280x has decreased with the increase of dag size. If you just use the standard benchmark which use the old dag size, you won't have an accurate mesure of the mining hashrate. 280X used to hash at 25-27mh/s with a good oc @1200gpu and 1500@mem but now it has decreased down to 20-22mh/s. The dag size increase continuously at a rate around x1.74 per year. you may try : https://bitcointalk.org/index.php?topic=1368785.0 |

You can mine Vanillacoin (blake-256)
the 6990 will do around 2.8GHASH.
Whoa! Pretty good. So why is GPU mining all of a sudden profitable? The last time my 6990 made this much was at like Jan 2014 mining Dogecoin. No it is not profitable. Vanillacoin's algorithm isn't Blake-256 but WhirlpoolX. However, I have no idea of what would be your hashrate. I was whirlpoolx, and it has shifted to blake256 But mining decred may be better.... GPU mining is profitable again, due to rise of BTC and huge rise of ethereum (which absorb most of amd hashrate power from GCN cards) I think : hashrate for other coins is lower due to the rush to eth mining, which leave space for small miners on others coins. |

As for "instant" transactions, that lasted about a day on Poloniex. Then they discovered it was probably a way for the Vanilla dev to force-feed them fake VNL in order to clean the exchange out of legitimate coins.

Are you sure about this ? what is your source ? Thanks |

i need quick response for these question
how much is one 970 doing in hashrate for ETH? and what is the argument to run ETH with it?
a quick search lead me to 980ti doing less hash than a 280x? why this?
Yes a GTX 980 ti has barely more hashrate than a GTX 980 and far lower than a R9 290X. Eth mining is highly dependant on memory : timings, controler, bandwith, cache... and as genoil discovered of TLB (buffer for memory adress translation) capacity/performance. For amd, hynix > elpida due to some timings. For nvidia samsung > hynix probably for the same reason. R9 290X with hynix mem and 1150 gpu is doing about 30Mh/s. R9 390X a small bit more (better memory I guess). Fury is aroung R9 290X/ R9 390X depending on the overclock. On nvidia side, GTX 970 seems to be the sweet spot with a good oc around 280X perf with lower power usage (the 280x used to be better but due to increase dag size, it has lost a bit more than 10% perf). |

While not necessarily mining you could become a host on the Sia network. http://sia.tech and https://bitcointalk.org/index.php?topic=1060294.0It's along similar lines as StorJ except it does not have a required collateral to become a host, however if your host shuts down and does not remain online for the duration of the file contract (6 weeks) you will not get paid. So if you get a power cut, you lose your paymentor that six week period? That's not too good, unless you have an extemely reliable internet speed and electricity supply. No, but your computer must be on and working at least at the end of the contract for sia. |

poloniexBBR markets frozen while we investigate issues with the network.
Posted by MobyDick
Now's the time to fire up a bbr daemon, run a miner, and support the network. Daemon will not sync, no solo mining. i don't understand beacause the nethashrate is up?  Hash Rate: 140.80 MH/sec from cncoin.farm Probably: the main pool is down and the network hashrate isn't enough to find quickly the next block at current difficulty. Main pool is down and difficulty is high : hence the problem to find the next block. Hashrate corespond to previously found block and will be updated with next block found. Present hashrate is probably very low. PS : the main pool may host some key nodes for network sync, hence the difficulty to synchronize. |

Is that the current hash rate and power consumption? The dag size is larger, so hash rate of most cards has decreased. The effect of the dag file increase is minor on R9 290 till now. |

Can someone please post results for the 750TI at NF17? hash/s and total power usage of the rig.
what is it NF17 ? I suppose n-scrypt with nfactor =17 |

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). |

There is some percentage of coins lost : difficult to mesure but real and significant. Does the "gas" used for using the eth network is "destroyed" or redistributed ? |

Yeah because we all mine X11  .. a nano does 26-27Mh/s @ ethereum (not oc'ed). Or 50$ per month. 450/50 = 9. 9 x 30 = 270 days. Thats why I said, Slow and expensive. Mine Etherum.. A r9 280x used to do 25MHASH in etherum as well. You can pick them up cheap at around $120 used. The nano can copy memory fast, but not faster in random access.. Due to tlb trashing, the 280x is not as good as before (incredible card : when you consider its age). I am mining ethereum with a refurbished R9 290X : 30Mh/s on windows 10 with 170W consumption, without bios modding (I regret being late to ethereum mining, but I had no longer amd cards till december). About 1.2 eth/day. Before I was mining spreadcoin with a pair of GTX 980 then a pair of refurbished GTX 980 ti with you private miner (I have waited spr rise before selling) : clearly profitable... (more than 2 btc obtained with spr, and I sold my GTX with minimal loss). But this is just a hobby with this small mining power : a mining which pay me my upgrades... |
