1. Nicehash or any other mining rental service is a terrible idea to use. Sure they pay you but it is a fraction of what they earn from your gear. Join a PPS pool - you will earn more.

I am new to ASIC mining, so any help would be appreciated.

What pool would you recomend? viaBTC takes a very large commission on withdrawals.

Minerstats says Nicehash is one of the most profitable (sometimes the most profitable of all!): https://minerstat.com/hardware/aisen-a1-24t.

2. I assume you are talking about Nicehash's AB pool? It sux big time to the point of needing the special driver that Canaan made to run their miners there along with NH having a dedicated AB connection address. The Avalons all work fine on non-rental pools and all pools these days will run AB if the miner can do it - no special driver or connection required.

Yes, Nicehash's AB pool, when changing pool to stratum+tcp://sha256asicboost.eu.nicehash.com:3368, the miners just stop. Strangely, I tried to mine on Nicehash pool using an Asien A1 miner, well, this one refused to start on Nicehash normal pool, but works just fine on Nicehash AsicBoost pool!



Just make sure the MM and OpenWRT are from the same release dates, they are matched pairs.

They are not all from the same release dates, there are some OpenWRT images that do not have a correspondent in the MM directory.

Also, there is a folder called Nicehash in OpenWRT but no MM nicehash folder: https://download.canaan-creative.com/avalon841/openwrt/

EDIT:

Success, I updated the miners to [Firmware Version] => Avalon Firmware for avalon8 - 20190711.

OpenWRT version is called Nicehash, this seems to work very well. MM updated to latest as well.

Not sure how to update PMU, if anyone has any idea about this, I would be grateful.

After the upgrade, miners do seem to consume about 100w less and the hashing speed seems a bit higher.

For 4 miners, it used to be about 54,xx, now it is 55,15.

Overall happy.

Thanks a lot for the detailed answer.

How to switch them to Performance mode? They are now doing 13,5Gh on the original firmware.

[Firmware version] => Avalon Firmware - 20180305

I was hoping that someone who already updated to Nicehas firmware would share the results. I guess I will try for myself, and report back. I realize there might not be a lot of interest in this model anymore, but hey, it might help someone.

Right now, on the original firmware, when using an AsicBoost pool, the miners behave very strange, and basically do not work. They keep on turning the fans down for a second and restarting (sorry, not sure if they are actually rebooting).

MM is the actual miner firmware.
OpenWRT is the miner controller software.
PMU is for the power managment unit (where the PCIe plugs are)

Just make sure the MM and OpenWRT are from the same release dates, they are matched pairs.

For OpenWRT open GUI and go to System > Backup/flash firmware to start things. By doing the upgrade from here you have the option to retain your pool & users settings. Um, if you have not done it yet, this would be a good time to backup the miner settings...

For the MM, after doing the OpenWRT and rebooting controller, open GUI and go to Status > MM upgrade and again do the obvious.
Can't say I've needed or used the PMU update, read the README for what it is about and how to apply if you want to use it.

AB is *not* a new algorithm, it is a hardware-based way to generate additional work for the miner to process and requires the miner chips to support it. AFAIK the 841 only supports AB when in Performance mode.

Yup, that's the way I do it.

Is there a reason why? I am trying to understand how to update my 841.

I see here https://download.canaan-creative.com/ there are 3 different types of firmware

- MM - how to update this?
- OpenWRT - this is just a matter of writing a new microSD card, right?
- PMU - what is this one? it is from 2020 so fairly recent

Also there is one called Nicehash, what is that all about?

I am already mining on Nicehash pool and working, although I did not update ever.

However, I know there is a new algo called AsicBoost, and if I select AsicBoost pool on nicehash, my 841 miners will not work anymore. Would this update solve the AsicBoost problem?

The Diff is their to help when renting.

To clarify my post above I have one 841 that likes to run on a 1200watt psu however my second 841 does not like it has it needs more power so I have confirmed
MM 2019-04-30 is working.  I ran one side on the psu and works.
My next task will be to operate a RPI- controller using the new firmware for that

And each A8 has an optimal diff far lower than 65k. The single 841's I have running in various locations have a diff of between 7.5k and 8k. What the pool cares about is shares-per-minute and they want to keep the I/O bandwidth low as possible. At Kanopool the target is 18SPM. Sending many more (lower value) SPM than is needed just uses more resources at the pool end while giving the same end result.

That's true, however when monitoring multiple PH seeing a drop of 500+TH when the pool changes blocks and you get all the current work/shares dropped and they are at a difficulty of 300k, the smooth line is better. Our reject rate has dropped substantially after lowering the difficulty and setting it on a per miner rather than per controller basis.

As an FYI, unless you have a very specific reason for setting diff it is almost always best to let the pool decide what diff is used by your miner(s).

There is a reason, if you have a full rpi the pool will provide a difficulty based on the total hashrate being submitted by the pi. Each individual miner's optimal difficulty is much lower than that. While in the end the hashrate should equal out, you'll see some drastic spikes on the pool. Setting a manual difficulty that matches each miners hashrate has keep the pool graph as a nice straight line, it also helps when monitoring units as they don't have any huge jumps in either direction.

Just updated one miner  with new MM firmware 2019-4-30. Working good for anyone wishing to update their miner. Left my RPI controller alone Avalon Firmware for avalon8 - 20181123.

Also working on 1200 w psu.

Code:
--avalon8-voltage-level 5  --suggest-diff 65532

EDIT.....nope went back to MM20181129.

Fine just second miner needed more power

Yea, really happy with the new fw. Been mining at a loss with my power rate and now that was cut in half. Let me know if you want to look at a live stream.

Over night getting 17.2th/s from UI, and 16.8th/s pool side at about 1450w.

Cool With good speeds and being fairly quiet looks like I may be able to replace the 2x throttled down 721's I have running in our inspection room with 2x LPM 821's and gain around 7THs at the same time Smiley

So far on LPM, -2 offset getting 17th/s at 1500w with two 821's fan pretty quiet under 35-50%.

HPM , +1 was hitting 23th/s but pushing 2700w, I didn't leave it there long before swapping to LPM.

Over night getting 17.2th/s from UI, and 16.8th/s pool side at about 1450w.

This firmware is good if you want to be able to easily switch between regular and low power mode. I installed when it came out and will be shutting down all 8 series today and replacing with S17. With the original low power firmware I was able to have 821 and 841 units on the same controller. With this firmware, I had to put them on their own controllers as the 821 wouldn't show up on 841 controller. No I did not attempt to flash the MM firmware with them all daisy chained and upgraded them individually. There is a bigger hash rate drop on the 841 than the 821. Both will hash around 9 TH/s.

Going to update my 821's at some point today. Best to update controller then units?

This seems to be one of the better firmware releases recently. Only tested on 851's.

There only seems to be a few issues with this, the power consumption in the "higher" mode is on the verge of 1900watts @ 15th/s the June release was  more around 1700-1800w @ 15th/s.

Balanced seems to give around 13th @ 1400-1500w

Low power is around 9th @ 900w

Trying one of their advanced cgminer-api commands and using their cgminer-monitor bash script there is an issue with cgminer restarting over and over (this is only if you use an advanced command and is fine if you aren't using that specific command), I made a work around bash script that  fixed this and will send it to Avalon for them to clean it up as I macgyvered it to make it work as intended.

The api frequency adjustment works properly in this release as well, instead of using the more options on the configuration section.

Now using the June release you can get similar results for power consumption / efficiency by manually changing the frequency and voltages in the cgminer config, but for a novice that wanted to use the lower power mode or if you want any of their more advanced commands this release would be "better". If you were a novice and just were going to use this in normal operational / high efficiency I would just use the latest June release to have a lower power footprint.

Also gave you some merit as I wasn't aware of an April release, my previous tests were on March and February. This release also fixed two miners that the March release broke.

Looks like some pricing changes form canaan on the 851 and 911. Embarrassed to say I'm not sure how long they've been like this though I know our pricing had been based on the $200 promotion anyway.
