Topic: Bitmain Launches the New Antminer B3 Miner - page 12. (Read 16352 times)

Hi guys, so far my B3 can only mining less than 18 BTM Per day.
It's definately not match with what bitmain sales told us before.
Even the 1050 ti GPU miner has the same hash rate, but the GPU miner price is much lower than B3.
These information was unrevealed during the sales.
B3 customers in China complain about this issue and try to negotiate with the management of bitmain to see if we can have an additional refund.
Let's fight together,  submit your complaints at bitmain website, thanks

Same issue here. I can't see my address on the blockchain which could be a problem. Perhaps it will appear after I receive my first payment.

I’m in the same situation as you using 1.02 with an account created using 1.0 on the MainNet.
My TX status has been in “paying”, for the full balance since I’ve started mining, and my wallet does not appear on the explorer. Wallet starts with bm1 just like all of the wallets associated with transactions on the explorer. The only thing I can hope, is that the “address” won’t appear on the blockchain, and thus the explorer, until a transaction has actually been created.

I got what I think is my BTM account PubKey from the “accounts” tab, after pressing “View detail” and scrolling down to “Addresses”. I used the address corresponding to the label “0”.

I think we all did the same.
If this doesn’t end up being the actual process to create a valid address, and all of this BTM ends up being sent into oblivion, that would be the end of Bytom. As I’m sure hundreds of users have done exactly the same as us.

I think its more likely that Bitmain just hasn’t sent a single MainNet payment yet.

You know, I know you’re right. There’s very likely some overtaxed component on the DCDC chain that needs the airflow regardless of how cool the chips are.

I will probably end up frying these guys.

But from a PCB/Chip temp perspective, I am 100% confident that there’s enough static pressure with two of these quiet fans. I’ve been running a decent QTY of Sophon SC-1 cards since February of this year, and have had no problems running the chips up to 80C while pushing a constant data stream through the API.

From the tear downs posted on other threads, we know these miners are indeed powered by the exact same BM1680 as the SC1s. So Im just working from that frame of reference.

An SC1 running a full and sustained workload will pull about 85W on the 12V rail of our servers.
A B3 is 12 BM1680 chips. We know they’re not clocking in at 1020W, so the TPU ASICs are likely not running full clip.

They’re likely low corner ASICs with too many dead cores to run in a Sophon product.
There’s also no external DDR in this configuration. So there’s a few watts shaved off there.

Given that bitmain usually has a habit of running about 80-135W per PCIe connector, it sure looks like they were expecting it push about 600-750W. The heat sink is a beefy structure. They also used thermal pads between the hashboards (making contact with both). This is a first for Bitmain if I’m not mistaken.

All signs point to a device that either didn’t reach its potential after development, or one that has a LOT of headroom to grow as a more functions and op codes are added to the BYTOM (or other Tensority) blockchains.

If the power consumption goes up when that happens, and I haven’t fried my miners by then, I’ll swap the stock fans back in.
Maybe it won’t be 114F in my garage when that happens.  

Does anyone have it now? With an approximate price of about $ 2,000 USD, shipping costs from China and $ 120 USD daily earnings and electricity usage costs, are they worth it?

I downloaded V1.01 of bytom wallet early May and have had BTM sent to this wallet from antpool but it is in status paying. I can't find my wallet address on the explorer. What will happen to these coins? Are V1.01  addresses invalid?

That was like 6 months ago.

Didn't happen with mine.

Probably it will be replaced by BTM Mainnet tokens.

Why? It seems the coin is being pumped. About 24% up now.

Oh ya. It is 12 volts haha
2000rpm isnt smart. The current fans can go above 5000+ rpm easy. U dont want them under cooled and risk damage.

For those who upgraded their fan, you can skip the fan speed update and just perform the second update for the hashrate.

The problem with the fan speed update is that it will set fan speed to 50% so your replacement fan will be too slow to cool the B3 down.

Stock fans are 1.8A@12V. Everything in those miners is 12V. So about 20-25W per fan.

Switched to Corsair SP120 [email protected] (12V  ) and just a hair over 2000RPM.

Only idiots use Binance anyway

Bytom delisted from Binance

I readed a bit into it and think this is for  you:

and a video about it from the bitmain support forum:

Seems you have to manually flash your SD card.

Tried to reset the miner but it didnt work, holding the reset-button for about a whole minute doesnt do anything. It doesnt respond and stays in the warming-up fase..
Do you have another solution?

I don´t see any differences in temperature if i use it with 2 fans or if there is only the one blowing in, except the noiselevel!!! Looks like the 2nd is ineffective atm, i tried both options for more than 12 hours, even with the new firmware there´s not one degree difference at my miner betwenn 2or1fan. Anybody with different results?

I kind of assumed this since this is the first antminer I’ve owned that you can’t alter the clock speed of...

Why? Because we may end up having to test every now and again? I’ll tak my 30d drop, thanks.
