At the rate x11 miners are evolving it wont be long till there's at 1 th machine, is too risky, too many people getting burnt on machines that are only months old.
Not likely, we are seeing an upper bound on efficiency given current market conditions for X11 coins. SPx36 is ~8J/GH, X7 and U6 are both ~5J/GH. |

Add to the build options? |

Innosilicon just released a 500 mhs miner at 750 watts, no sure who is buying a it with progpow algo change.
They didn't just release it... it's been available for over a year |

Lyra2Rev2 is a mining algorithm and it has been dominated by the Dayun ASIC miners for over a year now.
The FusionSilicon X1 kinda spanked them though, nearly 30% more efficient for same hashrate, came out 6 months before the Z1 pro, and is half the size  Also, Dayun doesn't make the ASICs, they're just a reseller. The manufacturer is PinIdea / Zigminer / OWMiner. |

What's the difference between a pool and a party? >_>

Not all chips can handle an overclock, that's why they ship with their default frequency. The chips are rated to work at their factory frequency only.

You don't see any negative impact over a single miner controlling 75% of the network? They could attack the chain at any time until the hard fork (2 months away) with ease.

It's not feasible, they need to have servers to handle nonce validation.

You could probably mine something like Wownero fine, there's little network hash rate and it is CPU mineable. 500 laptops at say.. 65 H/s is still a good 32.5 KH/s, 635 wow per day at 220 sats ~ $4.75/day :p not very profitable, but it is possible!

A copy of the firmware would be nice for determining what's available. Hardware photos, too!

guys, this thread is from last year. the hardware exists, and does what it said on the tin. we also know that bitmain wasn't the original culprit secretly mining, their rigs didn't even ship until way post-fork. baikal was confirmed to be running secret ASICs as early as august 2017. also, there are a number of coins that still bring in pennies per day from these algorithms, keeping people moving towards their 10 year ROI  that being said, there are new ASICs on the network again, but little clue as to who is behind it. unlikely they will try to sell the rigs after the fact either, since it went so well last time. |

I heard a rumor a few weeks back (Jan 19th) regarding ASICs on the network - supposedly there was a batch of 5000 miners manufactured for a private Chinese farm that went online just recently. It seems to be pretty feasible after comparing against some analytics done on the nonce ranges of historic blocks: https://github.com/noncesense-research-lab/nonce_distribution/blob/master/nonce_distribution.ipynbConveniently enough, this analysis concludes the miners came online around Jan 9th. Some chit-chat from IRC matches up as well: <@solar> i got some confirmation about asics too
<@solar> there's at least 1 group with cnv2 asics, 65nm
<@solar> supposedly a batch of 5000
<sech1> So after a thorough analysis of the winning nonces for blocks 1760000-1765000 I can say this about ASICs that are on the network now:
<sech1> 320 cores (10 chips x 32 cores?)
<sech1> each core processes nonces with 2^22 step - from 0 to ~1.34e9
<sech1> Single core speed is 400 h/s - calculated from the area of spikes (which come with 2^22 step) on winning nonce graph
<sech1> Overall ASIC device speed = 128 kh/s (400*320)
<sech1> Around 4000-4500 ASICs online now
<sech1> M5M400 they do mine on public pools: f2pool, viabtc, poolin - they all submit blocks with winning nonces strictly in ASIC nonce ranges
<sech1> all 3 are Chinese pools ironically
<sech1> so we can just count them in "unknown hashrate" part
<sech1> which leaves only 230 MH/s known
<sech1> and 641 MH/s = almost exactly 5000 * 128 kh/s solar
At the time of this post, network hashrate is 850 MH/s (640 MH/s being 75% unknown), putting us squarely in the danger zone for network-level attacks. This is also a major drain on public pools - with only 230MH/s of "legitimate" miners popular pools are operating at a significant loss, having only 60-70 MH/s on average (e.g. SupportXMR at 0.6% is just below $1300/mo, while their server expenses are approximately $5000/mo). With the next hard fork still a few months out this is a completely unsustainable scenario and will eventually lead to the closure and consolidation of the public pools, not to mention a mass exodus of "legitimate" miners. |

I meant "legitimate miners" to mean CPU/GPU miners using publicly available software and commodity hardware. It excludes FPGA and ASIC miners.

Because it doesn't do anything for nVidia drivers.

Nice cargo cult behavior right there |

Probably - they've been shipping 14nm scrypt miners since August so there's no reason to doubt their lyra2rev2 chips are also 14nm - zigminer is running two fab gens behind so they can't get the same type of density

There's no updated software for old CN ASICs. Some manufacturers do have CNv2 ASICs though, don't expect them to ever be for sale though.

You need to check the actual X server logs, /var/log/Xorg.0.log or similar

Most of the algorithms are fairly low power output, so you can turn the fan speed down in the web interface. Only X11 uses the max power draw (1.3kW), Quark and Qubit use about 800W each and cause moderate heat output, the remaining algorithms are around 400W and will be stable with low fan speed.
