broke my avalon controller and can't find cgminer anywhere

[deusopus]

Did you follow that link to Hagg's setup & use guide?
Start at section 4)2. which where you start by burning a disk image to the micro SD card. It then takes you through al of the remaining config steps.
The links in his guide for software are shut down so use the files you get from the link DaveF gave.
As for you choice in More Options: Lose the auto tune for one. The miner does it already. For the rest of the commands, use the ones in the forum link I gave earlier where I gives many different settings to use.

yes went through it. ill go through it again. i wonder what the firmware for the miners is and which image controller image corresponds to that. also i think my sd card is too small. its an 8GB. i ordered some larger ones from amazon. the only reason this gets me going is because i was 4 days away from a payout and i was gonna get one more payout before the halving. whoever set these up originally really knew what they were doing because it would always just work. i shouldn't have messed with it. they were screaming.

thanks so much fuzzy

Regarding the firmware: If the miner FW and software versions are different the miner GUI will still work fine but the miners either do not show up on the LuCl cgminer status tab or if they do show they have zero stats. You can use the upgrade miner button (I think located on the System tab?) to apply a different firmware .mcs files you have downloaded and saved on your PC.

Use the openWrT software image from April 2018 and the April 2018 MM firmware (or the March 2018 ones if you want).
This is cgminer status from my 841's but the 821's should look the same https://imgur.com/jcTE6fR
In that pic, under Avalon Device status the MM column is miner firmware version. All miners attached to the controller MUST be running the same version.

i just did the bare minimum configuration according to that guide. fingers crossed

Did it work?

If not post the log file so we have a bit more info to give you advice.

Also take a look here: https://www.zeusbtc.com/articles/asic-miner-troubleshooting/1653-how-to-troubleshoot-and-repair-avalon-721-741-761-821-and-841

With what you have posted so far it's a bit difficult to dig into it.

Side note, unless you have free or just about free power as in below $0.04 / kwh you are loosing money running these.

they are working but im only getting 20 TH/s with three of them going. I was getting upwards of 40 with the setup that was on there prior to my breaking it. and yes i live in central washington where the electricity is 2.8 cents/kwh.

UPDATE:

well i effed around with overclocking and burned out a couple of my power supplies. now i only have one of my miners running but its getting a good hashrate considering how old it is. .

$0.028 KWh I'm jealous.

Tough call as to buy new power supplies with the 1/2ing coming.
If you can reuse them on something else after might be worth getting a couple.
If you can't you will never ROI them.

I don't know if you can sell the units themselves. Considering you can get a new very quiet 4TH (ish) 160Watt miner with a power supply for $130+ shipping selling something that does 11TH (ish) but needs 1200 watts and has fans that are loud is going to take a while. People may want them because those old miners were just about indestructible and were fun to tinker so you do have that as a possibility.

Personally if I had the space I would keep them to tinker with.

haha yeah. i live out here in central washington near the confluence of two rivers and there are about 4 dams within 20 miles so we have a surplus. remember the GigaWatt mining company? that was out here. anyway, yeah these miners are tanks for sure. i think my buddy has some more miners. i was just talking to him. he's the one i got these from. he said he could hook me up with some more better miners. good friend.

For what is going on we need to see the cgminer status GUI page like I posted https://imgur.com/jcTE6fR
That in itself will show the main status of all miners connected to the RiPi controller.

Avoid the A921 & 950. In Canaan's rush to be 1st-to-market with a 10nm chip they rather blew it. Running full speed for just over 20Ths they are very hot and pull just over 2kw, Normal mode is a bit cooler, ~1.9kw & ~18Ths. 2x A841's do better... That said, as I posted in that setting link the A9xx are just as tweakable as the A8's.

So only 1 miner is connected and powered on? Obviously that combo of MM firmware and the OpenWrt work so as long as the other miners have the same MM version they should all work.

yeah about that.... just this morning two of my PSU burned out

[deusopus]

here is the readout now 6 hours later...

[NotFuzzyWarm]

Looks fine. If you can get some A841's they are a bit better speed and power eff - just need a different Raspi because you cannot mix miners on 1 controller. Even at full speed the 841 only pulls ~1.3kw so a 1.5kw supply works fine.

thanks so much for your time fuzzy as well as everyone else that contributed to this thread. i learned a lot.

btw...

these are the extra options i am running...

Code:

--avalon8-voltage-level 8 --avalon8-voltage-level-offset 0 --avalon8-freq 800 --avalon8-freq-sel 3 --avalon8-fan 75 --avalon8-temp 70 --avalon8-smart-speed 1
