sorry, no link, I was just reffering what was stated in eastshore message, which I obviously read it in the rush, where it says that they are on brink of bankruptcy btw eastshore is doing great and will be my first choice for buying next mining equipment  I know couple of mining farms which went in balls deep with these miners. And when they where supposed to be shipped, they where trying to do refund as the specs changed. But Strongu refused to give them refund. This might be one of the reasons why they possibly could make bankruptcy. |

4gb gpus will be done for on eth in few months. I wonder if 4gb cards will be obsolete if eth go progpow and/or if dag will be used/relevant with progpow. I believe pos will come before 2022, october 2021 to be exact.
Dag file will reach 4gb late December this year, so still nearly a year you can hash with them eth and etc. Eth mining algorithm don't think ever will be switched, its not that big of a deal. Its not the same as you where mining BTC with gpus and the ASICs where released. The mining efficiency gap is not that big, to make it centralized for one asic miner manufacturer. This A 10 is well overpriced. Biggest risk you'll have is quality of the miner ,hashing boards start to die after 180 days. They are not as reliable equipment as GPUs. |

I just had one of the ASIC boards die  . It's been running for about 20 days! I bought it through Crypto Miner Bros. I'm reaching out to anyone and everyone to get a refund, replacement or something before this $1900 (pre-order) miner becomes a paperweight! It's been slightly profitable in mining, but after you include the cost to set them up (power connectors, cabling, etc.) I'm deep in the hole. I'd suggest you stay far away from them. Far far away! No way, does the whole miner stops when hashing board not working on these? This is why i hate asics . People say that is easy setup mining including me  , but actually they are not as reliable as GPUs, CPUs and FPGas which is accessible to everyone. And 70% people who ever buy they most likley will loose money. 1900 for one miner? This is crazy for the performance they have. We had few orders with 1850 , with the specs advertised 660gh. But we shipped to our customers 2x miners as Strongu compensated us for the hash loss. |

New Antminer S17 Pro arrived today and plugged it in. It boots up, I can access the web UI, I set my pool, and I set it to "Low Power" mode for testing. After hitting apply, the fans spin up -- similar to the S9 -- and I'm expecting to start hashing about 30 seconds later. Instead, after about 60-70 seconds, the red "Fault" light on the machine starts blinking. Fans keep spinning, web UI still works fine, but it's not hashing. I've verified that it has an internet connection using the network diagnostics tool in the Antminer Web UI. And the pool isn't down because I have other S9s hashing on it right now. If I put it in "sleep mode", the fault light turns off -- although it still isn't hashing. Trying to set it to Low or Normal power mode causes the blinking again about 60-70 seconds. I captured the entire kernel log here: https://gist.github.com/tjwebb/8f75822baf28f346110ffca359790364. I don't see any obvious failures there, but any insight is appreciated. Latest bitcoin Antminers are bad quality. Ill have same problems , kernel log shows it has initialized fine but doesnt mine and then reboots after while. It is most likely one of your hashing boards died. At least i disconected one and it was working fine after. Sick of these asic miners, installed 5 of them in my mining farm 3 of them have issues after 2 weeks. |

I think i have the latest firmware on and there is no change. Let me double check and get back to you. |

Sapphire, reference card (blower turbine fan).
Not sure about the RX5700 reference card , but have had bad experience with reference cards in the past with RX480 few of the cards stooped working after few days. The OC you are using doesnt seem like it would affect the gpu, its always number of things not just one. Maybe the memory cooling is very bad on these cards which could made issues. |

Thank you for reply. I'm forced to use Windows as operating system, on that rig couple cards works with Phoenix, couple with Nicehash. So, 920MHz is SAFE for 5700-5700 XT memories (if is achievable under windows)? If is SAFE, is there any ideea why 2 cards died with 920MHz memory? Bad lot of cards, or?!? All power supply are Corsair, so good ones, measured under load is around 12,15Vdc, in idle 12,18Vdc. Cards not exceed 65-68 celcius degrees. What brand of cards are they, are they the reference version? |

A friend of mine bought 4 cards Sapphire RX 5700, simple, not XT.
Those cards works with these settings, for weeks, no one problem appeared.
Also on the rig with 5700XT, I have attached one Sapphire 5700 non XT too, (identically as mine friend own), it works perfect for 3 days, set at -24% power limit, GPU clock and voltage left untouched, mem at 920MHz.
Any ideea why my friend cards died?
Is too much 920MHz for memory?!
My XT and non xt working perfect for 2 weeks now. Using hiveOS. Hashing avarage 53mh for non XT and 54.5 for XT version stable. XT mem oc is 940 non XT OC is 925 https://www.youtube.com/watch?v=Du3xFR2Ug2w&t Image might be quite small to see, original image here https://bit.ly/2ZkSOTn |

It's not the market at the moment to be buying hardware. Save that dollar for buying coins
It's all about making the right decisions. But this GPU to me seems currently the best choice when(if) profit returns. Really want to see performance on different algorithms, but very limiter miners which supports these cards. |

It makes much more sense to buy eth now then mine it. |

 AMD graphic cards has been very popular for mining, specially for ethereum mining. They have been best price per has and hash per watt since ethereum launch. Previous generation cards (RX 470 and RX570) was widely used on mining farms. Also the latest generation cards RX5700 has now been very efficient for mining ETH. I do understand that Profit is still very low to invest in GPU mining rigs, better choice would be to purchase coins now. But if the markets returns where it was in 2017/2018 , this would be the mining card to choose. As they are quite efficient. So the test bench i have : 12xGPU all in one case 12x RX5700 MSI 8gb graphic cards 2300w power supply Best Results for mining Ethereum got from this setup with 100 accepted shares: 640 mh/s 1770 watts There is settings to add in Phoenix ethereum miner : -openclLocalWork 128 -openclGlobalMultiplier 4096  By adding these 2 values to configuration you would be available to reach up to 70mh/s per GPU but with 30-50% invalid shares. Tried to change OC on graphic cards but that does not help. video : https://www.youtube.com/watch?v=Du3xFR2Ug2w |

Wow what a difference in advertised wattage/Hash, that one really hurts. I got hit hard with the D3 from Bitmain and I pretty much swore off asics then and there.
Yes got hit really hard on D3 also, had a lesson didnt go in to heavy on these STU-U6. Think the safest if you really want an asic is to buy latest BTC miners, as they have the most advanced technology as it has been the oldest. You could get lucky and your miner could be profitable for few years. |

Yes got the extra units, but really no point on them as the cost of power is to high to make profit here. Better less units with better efficiency  Maybe that's their game. Advertise ridiculous efficiency to justify an inflated price for inferiour equipment just to get the sales. Then they give away extra units when customers complain and still manage to make a profit. A plausible way to liquidate old stock. Interesting business model...ha |

I got mine in early November. Haven’t seen anyone get 660.
You should have got extra units as compensation from StrongU.
And these units are heat sensitive, 75C on chip and they re-start.
Yes got the extra units, but really no point on them as the cost of power is to high to make profit here. Better less units with better efficiency |

Anyone has tried the -openclLocalWork 128 -openclGlobalMultiplier 4096 For RX5700 , my XT gets up to 64.5 mh/s but they are getting about 50% incorrect shares. Anyone has found fix for this? http://prntscr.com/qbz3sk |

Something about those numbers doesn't seem right.
1300 / 2050 = 0.634146341
440 / 660 = 0.666666667
Allowing for error these look pretty equal. 50% more power for 50% less hash.
Coincidence?
Well yes about 1/3 less efficient. But i assume the power would be less 30% from 1300 if one hashing board missing...ha . It is other way around. |

 So StrongU STU-U6 miner for X11 mining algorithm is been a big failure. On pre-sale few month ago i purchased it with advertised setting 660gh/s at 1300w .Which to me looked like a very attractive deal. But as usual with Chinese asic manufacturers there are problems, the deal seemed to good to be true. So finally we have received the miner which supposed to deliver in October 2019, but got delivered in December 2019. And delivered not as it was advertised, received specs : 440 GH/s mining speed 2050 power usage from the wall This supposed to be the most efficient asic miner for Dash coin , as the Spondolies SPx36 miner is very overpriced and uses lot more power. Dont get me wrong StrongU STU-U6 is still most efficient publicly available Dash Coin miner. But it is not as efficient as it was advertised. My power cost is quite high and watt per hash was 2x better when pre-ordered, and received a miner which nearly doesn’t cover my power cost. I seen some posts that some people have ordered before me and have received miner with the specs it was advertised. So i assume they have had some bad silicon run or some other issues why they cannot reach full performance. Has anyone received full performance 660gh at 1300w?

Hitting 15kh/s + on 3900x now. Could prob push it to nearly 16kh/s but 15 keeps it under 200 watts at the wall  Is it with MSR mod? What's your memory setup and CPU speed? Nice stats, 15 kh/s really nice performance on 3900x |

guys who where telling me that 2 memory sticks will be cap, and there wont be any speed increase if i add more memory where wrong. Ading 2 more sticks to my current system increased my performance by 10% without any over-clocks. Video : https://www.youtube.com/watch?v=xeVhjAfgMqw&tThat is an interesting find, I would not have thought that anything other than dual channel memory or quad channel memory(in a system that supports it) would have an impact the hash rate. It makes me wonder if populating all the memory channels in a threadripper system would have similar results. I do not think the gains are enough to warrant the extra memory, but it would be a fun experiment just for the sake of science. I like your build in the video, the MSI cards look pretty sweet Yes its all about caclulation best price per hash. Like my RAM was quite cheap 3600 mhz 8gb CL19 was 50euro for a pair. So it makes sense to pay extra 5% to get 10% speed increase. I wonder if i had better quality ram, would it affect my performance. P.S man these MSI RX5700 are so sexy they really feel premium cards in metal case. |
