Back in 2014 some of the early ASICs could (like Zeus products if I recall correctly).
Key is that Litecoins "scrypt" is just nScrypt with a N=10. The Zeus products (and the promised-but-never-delivered GAW Vaultbreaker) could go up to N=12, but with rapidly declining hash rates. Vaultbreaker was suppose to be able to handle N=14. Its why alt-coins like IMACredit used an N=16, but they were before their time. Back then, it was all about the fastest hash, unlike today where things like ZCash's SOL run at similar speeds and are obviously acceptable.
What I didn't know is if the L3 had N hard-coded or not.

Recognizing that "normal" scrypt is the hash function called with N=10, I'm wondering if the L3 has that hardcoded or could be coaxed into running with other Ns?

There are 3rd party firmware packages that will restore SSH, although they also have an Find Miner option so you may not need to power off.

If you care about money, there are at times coins / pools that pay better then BTC.
You don't have to like BCH / BSV / PPC / BCA or just about any other SHA coin.
You don't have to like Nicehash or any other rental pool.
But if they will make you more BTC to mine there / those coins that you have to convert to fiat to pay bills, and you are not mining there / those coins then fighting over btc.com / viabtc / slush / kano is a waste of time.
BECAUSE IF YOU ARE NOT MINING THERE / THOSE COINS, THEN YOU ARE NOT FOLLOWING THE MONEY AND IT'S ALL IRRELEVANT

Off topic Dave. That said: A quick look at coin.dance shows BTC being 8.3% more profitable to mine than BCH, and 53.8% more profitable to mine than BSV. When you mine altcoins your mostly speculation mining, hoping the current loss is made up by some future spike. Profit mining pools are risky: They look at the current price of a coin at some exchange or two, figure the difficulty of finding a block, and go with the most "profitable". However, the price of that coin is likely to be different after 100 confirms, when it can be exchanged for something else, so at the time of exchange it may, or may not, be the most profitable. Few, if any, profile mining pools check the order depth as well. Its pretty easy to overwhelm an exchanges order depth with profit pools. |

Did you flash the pi first and then the MM's?, it might have started one of it's restart loops while the upgrade was in progress. I've never had that happen but I have had the restarts interfere with commands.
But glad it's working now.
Ancient history, I suppose that was possible. I do recall the MM flashing not being clean and having to repeat it a couple of times on some of the PIs. Guess I missed that unit when checking. Thanks again. |

This and also it looks like you are running two different MM's [MM ID2] => Ver[8411803-14b0f10]
DNA[0139b1652f8513b9]
[MM ID3] => Ver[8411904-1ab9760]
Thanks for catching that. The problem child was the ONLY unit running the older MM. Not sure how it was missed when I upgraded last time. After re-flashing MM, the unit appears to be working fine. RE: Power... I've come to trust the PG ratings displayed on Avalons. Anything other than 15 is a problem that I fix. This unit was 15. |

I have (48) Avalon 841s all using the latest low power mode firmward. ONE has recently started having problems:  A841S-3-2 has failed to respond to reboots, power cycles, cleanings, etc. Any suggestions? |

Guess it boils down to estimating my downtime and see if that is more or less than the $2500/year those other two would cost me over Slush.
Using the numbers above, Kano would win by $250/year over Slush, and $2750/year over viabtc or btc.com, if my business could adapt to Kano's variance. Currently, our confidence we will be running next month is not high enough to make that call, nor do we have enough banked to weather through Kano's ramp up period, although we evaluate that regularly.
Thanks, I do appreciate the conversation.

I don't go offline very often, and the "ramp up" is measured in hours, not days or weeks. Yeah, my systems blink occasionally, but that hardly registers on Slush. BTC.com is claiming 1.5% PPS+ like system with shared transaction fees, called fpps, per several sources (one quoted above), although I've yet found a statement anywhere on their site. fpps is described on their site. My gear is a mix of S9s and A841 running in high efficiency modes.
Nice site, and I love that they show their math. However the ViaBTC numbers are off, they are using the older 2% PPS 1% PPLNS fees I think Via used as a promotional several months ago. |

pretty sure they keep the tx fees and take 1.5%
how big are you ?
They claim transaction fees are shared. At least CryptoCompare things so (see link above). As stated in my original post, I run about 1.6PH of hashing. I've used ViaBTC before. Just reread their (easy to find, unlike btc.com) fee statement. If I'm following, they charge 4% of the block reward and 2% of the transaction fee using their PPS+ payout method. As stated, this results in a regular block reward payment and a variable transaction fee payment - which I have no issues with. Since I can't find solid, onsite, information on BTC.com I guess I'll just stop thinking about them. Then my issue simply becomes one of risk reduction via lower variance by paying ViaBTC 2% more on the block reward. That is a non-trivial amount over a year period for me. Quick math, using ViaBTC's number of 0.00003731 BTC/TH/Day: 1600TH * 0.00003731 * 365 = 21.79BTC/Year (all things remaining static, which of course they won't). So 2% on that is about 0.44 BTC, or about $2500/year. You can see why I'm asking... |

It's much higher than 1.5%
Any source for that? |

Pros: BTC.Com - lower fees (1.5% vs. 2%), FPPS (daily payouts)
Cons: BTC.Com - owned by Bitmain, operated out of China, FAQ is typical "Chinglish"
Pros: Slushpool - great user interface
Cons: Higher fees, higher variance
From a business perspective, where I need to maximize profit and politics aside, why wouldn't I want to mine at BTC.com?
ps. Running a ~1.6PH farm and need regular income to pay over $10K/month/USD electric bills, so simply can't afford to "ramp up" on any smaller PPLNS pool, even if they have lower fees. Although not really a daily decision, mining profits are marginal enough that profit is checked daily to make sure price and difficulty are still in line. Mined with this farm from November 2017 to November 2018, hibernating until April 2019. Now watching things closely.

Well, this approach could work (although there's nothing stopping manufacturers from developing ASICs for any cryptocurrency), if the cryptocurrency becomes extremely popular and valuable across the market. So far, memory-intensive PoW cryptocurrencies have been resistant against ASICs. But, they would need to keep increasing their RAM requirements over time in order to maintain themselves away from said hardware. Nonetheless, coins like cryply, Turtlecoin, and Hodlcoin seem to be the best bet for CPU mining these days.  Actually, the coin I'm hearing about is a bit of a throw-back and uses nScrypt, with a high N. Memory requirements are something like 64X Litecoin (which is just nScrypt with N=10). What sets this coin apart from what I can tell is that it doesn't support pool mining. Its strictly one miner, one thread, one wallet. Lightweight for a Windows or Linux box, running around 100MB in Windows for a single thread, although if I'm doing my math right, only about 64MB of that is for the CPU algo buffer. |

Right at 100 miners reverted to original firmware via sdhc card at this point. Its slow going, with 2 of us working, we can do about 5 an hour. 19 more to do this week and we are done.

I got it. Although the instructions weren't thoroughly clear on the bitmain page where to switch the jumer. It took alittle working on it but I finally did it. Thank you!
Too say the least. Took me several back-and-forth e-mails with Bitmain tech support to figure it out. But for others, its Jumper 4 - a 3 pin jumper. Simply change it to cover the other two pins. Then switch it back afterwards. Note: we have been using this as an excuse to clean our machines. Once the hard cards are out, there is room to slide the control card out (if you disconnect the front fan). You can boot the sdhc card without any any cards or fans connected. We simply place a block of wood on top of the case, place the control card on that, plug into a space power supply, and clean the hash cards while the sdhc card is doing its thing. Then reassemble. |

Hey ccgllc, I just mistakenly installed the new 2019 firmware on my antminer S9. I am also pretty sure I blew out a hash board in doing so as well. I installed the T9+ toolkit and moved the 4 jumper to the right position. Miner still isn't booting off the SD card. I am only running 2 hashboards at enhanced lower power now. I am running 110V power from the wall on a 1850W PSU. How can I troubleshoot the hashboard and how did you boot the S9 miner from the SD card?
It doesn't "boot" from the sdhc, it resets itself. After a minute or so, both the red and green like should be blinking together. Once that happens, power down, put the jumper back, reassemble, and it should boot back to the original factory firmware. |

I guess the other way to think about this is relative to the previous generation S9s...
e.g. An S9 running Bitmain firmware in Low Power Enhanced Mode pulls about 9.8TH at, oh, ~85J/TH...
That means your getting about 3X the performance at 56J/TH for about a 1/3rd less power. At $1500, that is like paying $500 for an improved efficiency S9. Relative to the ~$2K/S9 we were paying a year ago (ok, maybe plus a few months), that is quite the deal. Looks like e-bay is selling S9s w/PSUs for ballpark $250.
Wonder what that works out to in power ROI? Lets see, very rough math... assume $0.10/kwh, 850W/S9, so 2550 for 3 of them... x 24 x 30 = $183.50/month in power. The avalon will save about a third, so call it $60/month vs (3) S9s, so a bit over a year to break even.
Seems rather risky... Of course, mining Bitcoin always has been.

Hearing rumors of a throw-back CPU only coin coming up.
No pools, mining will only function via the wallet in order to foster decentralization. One wallet, one thread of mining. Yeah, VMs can be used but pools won't work.
ASIC resistant of course. That would be compounded by actively preventing pool software from working, which doubles as an ASIC and GPU block.
Thinking this has some possibilities... or at least will be fun to see how it progresses.
