I've heard from those in the medium/large scale mining business that an American manufacturer is starting up.  Does anyone here know anything about this?  Obvious benefits to that have had reliability issues and unfeasible warentee options.

Can someone do a sanity check for me? I don't want to get scammed.

www.microbt.com is their website.  Clicking on Product brings you onto www.whatsminer.com.  Are these legit sites?

There is not much inventory officially on the website, but the telegram link on www.whatsminer.com will lead you to https://t.me/whatsminercommunity with actually very helpful technical support staff (with admin tag), and Vincent, the VP of sales (with owner tag).  And if you intend to purchase in bulk, there is inventory...  Payment by USD is payed to a company in Hong Kong called INCHIGLE TECHNOLOGY HONGKONG LIMITED

We have the full experience of S17/T17 series failures as outlined in https://bitcointalk.org/index.php?topic=5217949.0 and https://cointelegraph.com/news/samson-mow-bitmain-s17-t17-antminer-has-high-failure-rate

Our experience is about a 15% failure rate. Some of the warenteed units suffer from the same problems and have since failed.   For those of you that would like to know about bitmain warentee procedure, please let me know. We are experts now. ill share my knowledge.

It is time to choose the devil you don't know... As for alternative units, there is much less information, so I guess I will ask the question:

1) What is your experience with the Whatsminer M3x units?
2) What is your experience with the Whatsminer warentee process, and can you briefly describe the process?  From their website, it looks like u need permission via tech support before any warentee work.  no details as to entire units need to be sent back, or if they accept individual parts... and who pays for them.

Cheers.

I have a dead hashboard on some T17 units that I would like to pull.  Unfortunately, the red status lights are hidden by the metal housing.  Is there a way to know which hashboard is failing in the unit based on logs or other information?  I am not on site and have to rely on people that are limited on techy skills so I want to make it straight forward.

Thanks guys.

So... Our employee shiped units back to Bitmain RMA from canada (to hong kong) costing us approximately $450 CAD per unit, he didn't blink.  This is nearly half the price of the units.

1)  What have you discovered to be the most cost effective means of shipping units back for RMA?

2)  We had a "DOA" unit, does bitmain have a replacement option for DOA where we don't get screwed for paying shipping on a product that never worked?

3)  What is the most cost effective way to get the problem fixed, whether RMA or other channels...


Thanks guys.

Hi Folks.

Could someone point me in the right direction for mining containers, preferably built out of china and CSA&UL Certified.  Looking for current generation compatible (Antminer, innosilicon).

Thanks.

Hi guys.  I have been browsing the forums regarding firmware for a while...  What I have gathered:

-firmware may break your miner (instability)
-2019 firmware takes away SSH access
-some firmware may let failing hashboards work again
-some firmware may perform better (cooler, less watts)

Its all very confusing. I am looking for the most stable, vanilla, asicboost compatible firmware that will work with my S9s. (and will maybe bring a dying hashboard back to life, and some units that will not come online at all).

What do you guys think?

I need your help guys.

The scenario:
200 s9 miners.  1 internet connection (300KiloBytes down 100KiloBytes up).  One premium router that will be the gateway to the internet connected to cisco switches, connected to the miners.

The problem:
throughput is potentially a problem, latency is not.

What is my solution?

1) Use a proxy.  Which one should I use and is simple / turnkey as possible?
2) Just connect miners without a proxy
3) Other optimizations
