At the risk of having this judged as being a thread hijack (I'm still going ahead with it  ), I was wondering what the best (i.e. cheapest) case would be for an Onda D1800 with 6 GPUs on it... It would need to fit the PSU as well I reckon. Don't want to splash out too much cash, but I'm thinking of moving this open-air rig to another place so I need it properly secured. If cheap is really what you're looking for, just go for a cheapo Rosewill or some knock-off brands on Amazon or Newegg.com. No need to bother about long-term sustainability. |

how much PCIe bandwidth to each slot? the full x16 lanes? or is it gimped to x1? does it run at full PCIe 3.0? or again gimped to lesser like 2.0 or 1.1?
how about the CPU specs? available to upgrade to something with more cajones?
does this actually fit in a standard 19" server rack? or is it too wide like all the other guys selling "4U server" setups? what about rails?
The number of x16 PCIe lanes available is limited by the chipset. These are not all full x16 lanes afaik. CPU is a mobile Celeron unit, which should be plenty sufficient for mining purposes. CPU isn't the bottleneck in a mining system. Yes, this is standard 4U rack size. This will fit in a standard 19" server rack. You can even see all the mounting points at the front. |

Should we expect the possibility to flash the rx 580 with an rx 590 for better performance?
No this will definitely not be possible because it's a completely different ASIC GPU chip. You could do this with certain cards like the VEGA 56 or some older 7950 GPU because they basically had a good ASIC quality but the manufacture just locked the extra cores and sold it for less. However it needs to be the same chipset for that to work. Yep, RX590 is an entirely different architecture. You can't flash the BIOS and wish your RX580 will become a 590. |

Bitnand just sent out a discount coupon for P104 cards if anyone is interested. They are offering $40 off on each card. Not a bad deal imho. They also accept crypto for payments. You can take a look here https://www.bitnand.com. Coupon code is "p104bitcointalk" |

Huge thank you to all the core contributors! We fixed the latest double-spend bug! |

After seeing the performance of RTX series, I am more convinced that the P104 is still the best mining card on the market. 40MH/s+ for around $4xx with the P104-100 is a really good deal imho. I don't think it's good to compare to AMD Radeon because per card hashrate AMD is much lower, and consumes much more power. https://www.bitnand.com/product-page/nvidia-p104-100-mining-card |

Does anyone know who's behind the Dayun mining company? It seems quite secretive with very little information available online.

Anyone got the latest RTX series already?
I want to know other algo performance, e.g. Lyra, Equihash (various versions) etc.
I feel like there has got to be something that RTX cards excel at. We must be missing something.

Given current ETH price ($175), we are better off keeping the RTX 2080 for gaming  The ETH price is $200 now, but it is still better not to mine with the RTX 2080. Yes i agree. The ROI takes upto more than a year if ever the speculation is true. It is such a waste of money and time. I'd rather plant some vegetables. Or just straight up buy ETH at the current prices.  yeah go to buy ETH is better not mine it and HODL until next year Yeah, though TBH, people have been calling Ethereum bottom since $700, $600, $500, $400, $300, $200... |

so anyone have tested this gpu? what are the perf on bitcore and lux?
We should see performance tests soon. The Bitnand.com guys say they're getting the first batch for performance testing in around 3-4 weeks time. |

It's speculative at this point.
I'd refrain from jumping to conclusions until actual measurements start coming out. Even after initial benchmarks, drivers and mining software could be better-optimized.
I'm not expecting a giant leap in mining performance either (certainly not enough to gamble on a pre-order), but I'm curious to see actual results.
yeah idk what the rush is, same with the ppl who all felt the need to jump on the fpga bandwagon early instead of waiting till products were actually shipping. I guess we never learn in this space lol To be fair, pre-ordering a gpu with a relatively reliable resale and a warranty is a bit different than plonking down 3-5x the amount on a permanently custom modded, community supported piece of tech. Not saying there are no pros to the latter, of course, but pre-ordering something from Newegg is totally comfortable for me, whereas giving $4k to a stranger in untraceable currency is...well, riskier. cheapest on newegg is $800 you can buy newrly two 1070ti or two vegas for that Prices in the USA are disproportionally cheap. Not fair...  Medical bills are insane in the USA IT EVENS OUT. Haha you caught a cold and need to stay a night at the hospital? Sorry bro, that's going to cost you dozens of RTX 2080 graphics cards. |

hashrate still nothing, however, gaming 2080ti x 1080ti = 35% faster, if 35% is confirmed then is a huge disappointment.
i think if game not support RTX function maybe faster around 10-15% A couple leaked reviews claim 30-45% faster with RTX disabled. Why is that the case? It doesn't make sense RTX function would drag down performance. |

Reducing the block reward will help solve inflation problem in the ETH blockchain. However, this will NOT be friendly to miners at all and may backfire.

The question I am wondering: How long under someone programs those new cores to do similar functions as the new ACORN M.2 FPGAs?
Are you saying program the CUDA cores? I am not sure if that would add any additional mining performance. |

The redeeming thing about getting RTX 2070 or RTX 2080 is that in 6 months time after you're done mining, you still have the fastest GPU on the market. This makes it easier to resell back to the gamers. How do you figure? All AMD needs to do is release a new series of GPUs that would make the RTX 20 series obsolete as well.. My opinion is that it is too late to get into mining at this point in time, whether or not you have free electricity or not. There are simply too many threats just around the corner that could leave you high and dry with computer hardware. The same can be said about Q1 2017. Crypto prices were not attractive back then. Those who started mining at beginning of 2017 are probably millionaires by now. |

Imagine if Bitmain gets a hold of these GDDR6 memory chips and uses them in their private ASICs.
I imagine one ASIC would be able to easily achieve 1GHS of Dagger Hashimoto speeds.
Either way, the ETH dev really needs to do something to keep the ASIC resistance, many miners even agree with taking a issuance reduction just to keep ASICs off the network.
Problem is that Vitalik doesn't give a damn about miners. Look at what he says during some of those Ethereum core dev meetings (vids are on YouTube). He thinks ASIC is not a problem up until this day. And then you look at the relative price of ETH vs BTC. Explains a lot, doesn't it?  |

there could be a surprises with RTX series if mining software devs find a way to utilize the tensor cores, if not the performance bump wont be that impressive considering the price point.
As the tensor cores are FLOATING POINT, while mining is an INTEGER function, as I mentioned back when the new Tesla was introduced I don't see them being a factor AT ALL for miners. You are staying ETHash algorithm is an integer only function? Are you sure about this? Some of the divisions in here looks like it utilizes floating point calculations. https://github.com/ethereum/wiki/wiki/Ethash |
