model a and spec was old draft, the firmware upgrades are for the 8 series at this time.
how fast for this to ship? I have auc from the 800 series will they work? |

Phil did you buy the A921? If you did will you review it and show low clocks?

@ yankees I just ordered 1 A921 I was able to use a cc got it from blokforge
with shipping to NJ and a small CC fee I spent about $397
Not worth it but I wanted to see what clocks I can do.
The A851 sucked at underclocks
The A841 was good at underclocks
I will post a review thread as I don't think any USA guy did this yet.

I was curious if the 8 or 9 series had the ability to use AsicBoost?
And if so, if there is an ETA to the release of the MM firmware.
I see in the Avalon 8 thread there was a new OpenWRT and MM released just yesterday, but no change log and not sure if it's optimizations or AB.

They are optimizations to lower power use to .085 J/GH at sacrifice of hashrate. Change log only states "Support low power". I didn't see any new settings in OpenWRT to switch between this mode, but possible there's an option switch you can add to specify mode. 821 hashes at 9 TH/s and 841 9.2 TH/s with default voltage offset of 0 on same controller. I don't have a meter handy to check actual power use, but they are running fine on 1200w HP PSUs and should be around 750-800 watts at wall based on claim. Not sure what voltage offset the .085 J/GH is claimed at, as you can sacrifice even more hashrate at -1 or -2. |

We'll it's really nice to drop power use if I'm going to mine through bear with these. Asic boost will be a plus if available.
Might be silly not to upgrade your older avalons at these prices if your planning to mine on.

Pretty sure the 7's and the 9's can have asicboost but the 8's don't have that capability. |

Interesting, what is the thought there on the 8 series? I might have to join a batch to upgrade my two 821's to A9's |

I have one a921 coming soon. I will setup a rasp pi for it today and when I get it I will post clocks
I paid 396 to blokforge I used a cc and will get a 2% rebate so about 388.
That includes shipping and duty tax.
I am really interested in the downclock features.
The a841. Could downclock and be more efficient about 880-900 watts at a 10th setting.
Maybe the a921 can set to 16th and use 1200 watts . We shall soon see.
Maybe it will use asic boost.

I'd love an official explanation of the new firmware as well as what models can provide AsicBoost now or in the future. Holding out on upgrading until I have more information. From what I am seeing there are no "savings" in efficiency just simply a way to use less power, perhaps for home use https://canaan.io/avalonminer-8-series-high-efficiency-firmware-released/ |

I'd guess that they will probably never support AsicBoost since you have to give up all of your current and future patents to license it. AsicBoost is still patent-pending. Anyone who implements it outside of their licensing (Bitmain) can potentially face legal action if patent is approved.

Merry Christmas to all.
I received my 921 yesterday and have it setup and running now. Performance is not optimal. At stock settings I get around 15 GHS and DH averages 20%. 11 to 13 GHS and 30% DH if I reduce the power settings. I am using a 2400 watt PS from Parallel Miner. I increased the Voltage Level Offset from the Default: 0 to +1 and now I am getting 18 GHS with DH = 13.774%. Not really the performance what I had hoped for.
Any suggestions on what to try? I am considering trying a different power supply. I can free up two EVGA 1600 watt titaniums to see if that will make a difference. I also have a Blokforge 2000 watt PS but I do not think that is enough to run this alone.

Hey there, I'm guessing you mean TH/S otherwise that is abysmal. You may want to check out this thread by Philipma1957. He just got one and has been playing around with different settings to acheive an optimal hashrate. There has also been some good info peppered in there by frodocooper about the firmware releases. Good luck |

how long did you run it 15000 is terrible but it takes like a day to get to real numbers. I get 18000 to 18500 with lower volt I get 19500 to 20000 with stock volt I get 20500 to 21000 with up volt so you 1) have bad unit 2) older firmware 3) did not wait long enough to get real readings 4) maybe the pool you connect has an issue. |

I'm not sure on significance of the device hardware errors. Both of mine also report them and I saw as high as 70% during initial boot. While running full hash, they seem to stay around 5-15%. With two, I'm seeing 39.2 TH/s average on pool with default settings. You may want to try to just let it run on default settings for awhile to see what you get. I had issues with the second one in chain initially and it was either from the controller having newer firmware than miners, PSU, changing default settings, or possible damage in shipping as the cases came with dents.
Initially I was using an old P3 2100w PSU that came with an M3 and trying Phil's settings. Thinking it was a power issue, I hooked up a Sorcerer to one board and the P3 to the other. I did this at same time as upgrading firmware and switching back to default settings so not sure what fixed it. I switched back to just the P3 PSU this morning and it's been running fine for a little over an hour. Only other thing with the PSU is that initially I probably had a couple wires off different legs crossed between boards. When I switched back to single PSU, I made sure to use connectors off same legs for each board.

Yes, I meant 15 THS, or 15000 GHS. Running for 12 hours with he +1 and hash rate is 17896 with DH @ 20%. I am not sure how to intepret the DH number. The hover over help says Device Hardware Error, so not a good thing I imagine.
The power supply is unlike any I have used before. I like it. Very small and pretty quiet. A single 220 volt input but it has two breakout boards like. I made sure to keep each hashboard on the same breakout board. One side is 12.6 volts and the other is 12.8 volts. No adjustments that I can see on the PS. Is there any way to see more detail on the 921 stats down to the hash board level?
I do not have much time today so I will let it run on the +1 for the next day or so and try to improve my setup later.

Yes. Instructions for how to do so and how to interpret the various fields and values may be found here, under the subheading " How to locate and open the CGMiner API Log." (HagssFIN wrote the guide with the A7 and A8 in mind, but most of it is applicable to the A9 as well.) |
