Avalon: Can I use same generation 8XX asics on same controller

[avalonmin3r]

I learned a while ago that I could not get a 741 to be picked on my 8 series miner. (running daisy chained).

But can anyone confirm I can run a 841 alongside my 821 I picked up? I think the firmware's are series specific such as 7xx, 8xx, 9xx.

Thank you.

Can you run them together? Yes. Should you do that? Not really. Just as with the A721/741 series, the 821 and 841 should have separate controllers.
One reason deals with firmware updates, an update runs on ALL miners attached to a controller and the MM updates are specific to miner type. An 821 does not like thinking it just became an 841... (been there, done that)

beside updates there is no problem

Yeah if you are not going to do any updates you can use same Rasp Pi.

If you do updates with such setup, you will face troubles.

All very true but it is still odd to see a cluster of miners with some of them running different speeds. What does not help is that which miner ID is which actual miner will change when a miner restarts on its own (or if you reboot it).

On mistakenly crossing the updates, if you do that a miner can still be accessed and set right. Just isolate the erroneously updated 821 or 841 from the others, apply the correct MM to it and all will be well again.

I was able to get an 821 and and 841 running together. not worrying about updates as it is up to date for now.

thanks for all info.
