The RX 580 will do ~315 H/s on ZEC. The Claymore epoch benchmark figures are just an estimate and largley overstated. In my own test with a five card RX 480/580 8GB and 570 4GB rig. The benchmark at epoch 129 for the five cards was ~143.3 MH/s, at epoch 130 the benchmark was ~142.5 MH/s. The actual current dual mining hash is ~144.1 MH/s dual mining with DCR. Even a 10% drop in the RX cards ETH hash in 6 months can be offset by addding a single $200 RX 570 4 GB card.
Where does the huge difference on ZEC mining coming from between 1070 and rx580? At ETH a GTX 1070 has similar MH/s than the RX580 but at ZEC it has 50% more (~ 480 Sol/s). From gaming perspective they are also very similar from performance. And yes, this is a serious question as i'm interested in technical details due to my work in IT business  ETH and derivatives are very "memory hard" due to the algo used - and as AMD 8GB RX-series cards have the SAME memory clocks and bandwidth as GTX 1070 cards, they end up being similar in hashrate when the memory access is optimised (the NVidia cards seem to use higher-performance memory settings by default in their BIOS than AMD uses). Other coins mostly use algos that are more core-limited, so the higher clocks on the GTX 1070 and similar number of cores vs the RX 470/570 make the 1070 quite a bit faster (the 480/580 have higher core count but clock a LOT lower, so the 1070 still wins there). |

They are totally fine, even an overclocked 1080ti won't heat up the splitter cable, much less an underclocked one. I am using such cables (though not your model) for a few weeks now. Your splitter cables appear to be at least 16 AWG though. |

have you tried a high core count cpu and as many drives as the core count mining in parallel? should equal to very high overall read rates as each drive will read at their max speed im thinking about ryzen or even threadripper for a 16/32 disk setup  FX 8570 (8 core) can't keep up with a SINGLE drive read speed, though with JMiner it's at least in the ballpark. Threadripper might, twice the cores and a lot better IPC - but I suspect it would be marginal on more than 2 drives at a time. NO BLOOD WAY would it keep up with 16+ drives, for that many drives you need a GPU to do the mining, and not a real low end one. Reads to the drive depend on when a new block is issued - I've SEEN very rare cases of less than 10 seconds between blocks, a LOT of cases of less than 1 minute (not sure if that's a majority though). There's a site somewhere that keeps track of how long each block runs before it's solved, broken down into segments like "1-30 secs" "31-60 secs" and such. For reference, my i7 6800K at stock reads 9x 8TB drives within 45 seconds, while mining monero with 7 threads. I'm quite certain threadripper will do a lot better than a 6 core broadwell. Which miner are you using? My FX can't get through *ONE* 8TB that fast - quite - while doing little or nothing else on the CPU - even using JMiner. Blago it gets less than HALF the read rate. |

Really no need to sell RX cards atm, people are just paranoid for obvious reasons.
Even if the hash rate drops, most of us got the cards for 200-240$, we will ROI a few times over by the time this bubble ends.
The ones that should worry are people geting in mining now, at high prices of cards and profits falling.
Folks that bought RX cards while they were still near MSRP have likely come close to paying for those cards by now. It's the folks that paid GOUGE pricing that might be in trouble. What's more likely to have a noticeable impact on profitability for ETH is the Ice Age "longer block times", which are a much bigger factor and affect ALL miners equally. |

BTW, QuintLeo, thanks for your subtle hints in altcoin forum, they brought me back. I thought that Cure is in much worst shape since Poloniex debacle, now pleasantly surprised.
Cure still hasn't fully recovered vs BTC from it's peak just before the delisting - but it's higher now on a $/coin basis than it was then. On the other hand, Team Curecoin PPD has more than doubled since then, so profitability IS down some. |

Guys I just want to revive my AMD 7970 GPU as a miner. Do you guys think it can mine decently with zcash? I just need some feedbacks and opinions about zcash mining and to find new GPU .
7970 = pre-rebadge R9 280X (bios mods and slightly slower RAM) - they should do over 300 sol/s easily with some OC tweeking. They're much better on ZEC than they are on ETH. |

Disclaimer: During the PSU supply crunch, I got a few "Ethereum PSU" from China.... until I get the EVGA-G3's and server PSUs.
So far so good but I am not very comfortable with the "poor man's PSU" so I use them when only needed and did not beyond 50% of the alleged watts rating. It however got all the cables, connectors required up to 6 x GPUs (6/8pins) or 3 x GPU (2x8pins) -- its the real deal.... but I don't recommend it unless you don't have any other choice.
Form factor on those "1800 watt" PS is WAY too small to be a legit 1800 watt - and I also find the "90 Plus" certification an issue, as there is no such certification. They look suspiciously like the 1100 watt PS I have in some of my Innosilicon A2 units. I'm not sure I'd trust them for *1* kilowatt 24/7. The "1600 watt" PS are big enough they MIGHT be legit. |

hello dev, please support SSL connection.
Why? There is no REAL value to a miner to waste the time setting up a SSL connection (it doesn't impact anything once it IS up, but it takes noticeably longer TO set up, which is one of my issues with Claymore in these days of pools getting DDOSed and going down for short periods on a frequent basis, AND his switching pools to do his "fee" stuff). |

The room is still hot but all cards are at 74-75°.
That's not a great temp but it's low enough it shouldn't be an issue. My "mining area" ambient has been a solid 90 F during the heat waves we've had so far this summer - but plenty of airflow and an evap feeding cool air into the "air intake" area helps keep the RIGS cool. |

Sadly they are not interchangeable, the GQ series seems like the odd one out as you can't even buy the cables from the evga site.
As for OP, what you can do is swap the psu end of an 8+8 cable with the psu end of one of your evga single 8 pin cables. You have to make sure the wires are aligned exactly as your other evga pcie cables. There's a youtube video of how to remove pins off a psu cable using staples if you want to give it a go.
The G2 series is manufactured by Super Flower. *IF* I am remembering correctly, the GQ series is manufactured by Seasonic. |

No, 1080 Ti's require 2 x 8 pins and the G2 1300W comes with 6 VGA ports on the PSU and 2 x 6+2 + 6 cables and 4 x 6+2 cables
That's 5 x 8 pins total (they might as well come with only 8 pin single cables) without converters meaning it can only handle exactly 3 pieces of 1080 Ti's.
I have 36x 1080 Ti's (4 different models) and 30 of them (3 different models) are using 8+6 pins. Only one of the four models use 8+8 pins. Huh, didn't know that but I can see the FE also has 8+6. FE is 250 watt TDP. Aftermarket - I'd expect quite a few in the 300 watt range, with occasional high-end cards likely pushing 350 ballpark. |

I forget how I managed it, but I got a web-based wallet of some sort working, using a "local server".
Might have been part of that "all in one" package and I do remember I had to go straight into the .bat file stuff to get it to work at all.
IMO any program that depends on IE being on a system is STUPID and should be ignored.
that is only one way to access your wallet, through a browser interface running local wallet. You can also run AIO wallet with or without local wallet - if no local, then you can use several online wallets. Also, there is Android wallet if you happen to use that. Also, I am sure the browser version runs on any browser not only on IE... I was never able to get the actual AIO wallet to WORK. I don't have anything Android and don't seen any probability of ever doing so. The web wallet isn't browser-specific - as I already pointed out I HAVE a "web-based wallet" working. |

Does "Claymore's ZCash AMD GPU Miner v12.5" compatible with 1070 cards? If so, whats the configuration for these cards?
Which part of "AMD GPU Miner" did you not understand? |

Got my first pair of GTX 1080 ti on the way (due Friday) - but due to infrastructure setup at the new place, it's going to be a dual-card machine.
The 3-card 1080 setup works OK from a cooling standpoint, with a Zotac mini in the outer slot - but the middle card IS the warmest, even with a card that's long enough to have one fan almost totally unobstructed.
I just wish 1080 non-ti hadn't started climbing a bit this past week.
I was going to grab some R9 390 cards from a local seller on Craigslist - but they never responded to my email, and didn't have a voice number I could try calling them at.

Why a new thread? what's wrong with the old one ?
You waited almost a YEAR to ask this? That's .... silly .... |

Do I need minimum of Bursts coints to be able to get revenue?
You need a couple when you're first setting up if you're using a pool, after that you do not. I'm not sure how it works if you try to solo mine. |

Can someone explain to me why the miner prints 6200 sol/s and the flypool the average efective hash is only 6050 ,shouldn`t be the same as it is written in the miner?
Pools estimate hashrate based on solved shares - which you're always going to lose a few on due to internet lag, you lose some when you're mining on a share and a new block shows up, and shares also tends to vary a lot. The hashrate at the pool will NEVER consistantly match what the miner is reporting, and long-term is ALWAYS going to be a little lower. |

oh boy, skip it for sake, 390usd just go pick r9 nano/gtx 1070, or wait for vega at august 500usd
Try FINDING a Nano or any Fury card for that matter - and the GTX 1070 availability is now matching RX 470/480/570/580 levels with price gouging having sent the price into 1080ti territory WHEN you can find one. Vega is an unknown at this point - they might be good for mining they might not. The "mining specific" cards should work as a second card in a Crossfire/SLI type setup, so there will be *SOME* resale value. Not a lot of one though unless another cryptocoin boom happens a couple-three years down the pike.... |
