Are any of you gents contemplating buying the 21k A11 pro that Inno has on 'offer.' I am itching to buy one for some weird reason and need to be talked out of it...

Im so glad I sold all my S17+ last year. They are all garbage quality, but thats not what you want to hear...

I would carefully try each hashboard one by one in the working miner to see if any hash.  If the ALL hash it is certainly a power supply/controller issue. Buy extra PSUs/controllers for these machines.... If 2/3 hash, the bad board is killing the good ones and not allowing the unit to work. Could also be a controller failure. You could try the good controller with the good hashboards (after testing) and see if that works. Swapping controllers sometimes works.

I used to use bitdeer quite a bit but they way the contracts are worded they almost ALWAYS win and you almost always lose.  Don't do it other than if you want to play around and watch their figures. 

My last decent purchase was 12 months ago buying s19pro for about .2 btc. It finally ROI'ed in BTC terms after mining for 12 months but that includes the Chinese drop which really really helped.  And this is with what they said <6ct power and no fees. Now power is 7.5c and every plan has extra fees and difficulty is really taking a shit on the returns.

I doubt any of their current plans will ROI unless coins moon and in that case it will always be better to buy btc directly.

Dunno while pricing seems scammy in a few months it actually may be legit. Value is dropping like a rock. Mine went from 3hnt/d to 1.5 after halving. Now at .3 - .5/d for the ones that are still working. Who knows what is going to happen next month but I guarantee these won't be making more HNT then...

I had problems with my s17s after a year (S/T15s were even worse!) Sold them all and moved to S19s. One failed during warranty and bitmain swapped it out very quickly.  It gets hot and humid here so I take extra precaution during the summer to keep miners under 95F.  Heat and humidity kills all miners.  If you are running where it is cold you should not have these issues.  I think they are about the same quality-wise. I really liked my first S19pro but then when the issues started I moved them to cool environment and have not had any problems for 4-5 months.

I ordered two. One is working ok and the other needed a new PSU upon delivery. Inno help email said 'good luck sending it back to us, because we won't get it or help in any way in case customs causes issues with the delay'

So I suppose their warranty might be valid in CHINA but I doubt it is worth anything anywhere else in the world...

I agree with original post. Garbage machines DON'T BUY THESE!

So... I finally got my win in a shuffle after trying 30+ times and it seems like this new RTX 3080 Xtreme is a LHR edition. NOTE there was no advisement from newegg about it being LHR. Nothing in the shuffle or on the box or sticker says anything about LHR. Its starts mining around 87mhs and drops to 47 very quickly. I'm super bummed. Do you guys know of any mining software that gets around the issue? Feel free to PM if its private.

Be careful with those screen shots Phil. I just had my SIM card ported and my email/coinbase account passwords reset. Coinbase's default 2FA authentication goes to your phone and your email is security is also garbage if its 2FA is also your phone. I guess they upgraded my coinbase (which was basically unused) to coinbase pro and I guess that gave them instant access to all crypto on the account.  Drained my bank account to coinbase and transferred it out to their address in less than 30 minutes...

I loaded the new firmware on a T15 that was taking forever to boot up and now it is rebooting itself every 30 minutes or so. Maybe it is a firmware issue, maybe it's the miner...

Has Anyone else have any issues with the new firmware? I went to flash the old firmware from an older T15 but it seems they have made it so we can no longer download backups from the interface. How can I find the old T15 firmware?

I had a lot of problems with the network error initially. But figured out I needed to follow the static IP setup to accept a new pool. I think it's a great machine so far. 28.5ths running full power. Over 18 in economode.

I put one in my garage and while there is a whooshing sound of air moving, it is nothing like the high pitched whine from S9's. the noise is easily bearable and much better than the dual-fan miners. Thank god! Note I have it venting into an AC duct so that helps some but other than that it's open.

This is 100% false. Bitmain will eat their 5 dollar fee. They did it several times for me last year.
