Bitmain Launches the New Antminer B3 Miner

[greyday]

For you folks who replaced your fans, be aware that with the new firmware that increases hash-rate, the chip temperature will also increase.  Might wanna keep any eye to ensure you're getting adequate cooling.

This is exactly why fans should not be replaced in the first place. Get those quiet box instead if u dont have a noisy place to put it.

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

Just thinking ... when you consider Bitmain could propably have shaved 10-15USD of their production cost per unit (x3000 units?) by not using 2pcs high RPM fans but using some other cheaper fans, and they can now add 30% hashrate with a firmware update .... makes me think the B3 has a lot more hashing potential than currently announced.

I also noticed in one of the first B3 youtube demos how high the utility rate was on the status page ... utility rate as in how effective the miner works (miner status page, top middle). My B3 utility rate before the firmware upgrade was 0.9 or so, now it is at 1,13 ... the youtube move showed 9,7 if I recall well (https://youtu.be/aavqAi--Z7k @5:05)

So I think the B3 hardware can hash a lot more than what Bitmain is allow us to hash currently, if my assumptions are correct, they have a lot of control over all parameters that determine difficulty, network hashrate and as such the price ...

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

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?

The miner doesnt get any further than the "startup" fase. Fans running slow and i think the miner does not get online. Therefore i cant find the ip.. any tips/tricks?

Try resetting - https://enforum.bitmain.com/bbs/topics/3957

yep, this should be the next step. Take a pin or needle and hold it as long into the "Reset-Button/Hole" (without much force!) until you hear the beep and see the red light. This should reset the Miner to factory settings. However, in case you have disrupted the upgrade process with unplugging it i'am not sure if this might be enough.... Hope so. Let us kow what happened and how things worked out.

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 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.

For you folks who replaced your fans, be aware that with the new firmware that increases hash-rate, the chip temperature will also increase.  Might wanna keep any eye to ensure you're getting adequate cooling.

Can confirm utilization increases in my end were less than 75W on two B3s @240V.
(Using one AWP for two miners)

SP120 LEDs still doing the job at 52C in a 25C room.

Wat was the total watts used per miner?

363 watts right now. Was at 338 before the update.
Keep in mind I’ve completed a fan swap. Those stock fans pull about 1.6-1.8A each.
The consumer grade fans only pull .25A. So I’m cutting a bit off the wall there.

Something to think about. From a regulatory standpoint, Bitmain can only really increase power consumption +-10% before running into compliance issues. Especially without warning consumers about an increase outside of the known envelope. The “changelog” for these updates were vague at best.

Wat fans are those and wat rpm do they spin at?? U are saying the stock fans used 160-180watts? That cant be right...

Well, at least now we dont have to worry about GPU at all even if their rates improve I would think

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

Switched to Corsair SP120 LEDs@.25A (12V  ) and just a hair over 2000RPM.

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.

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.

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

Probably it will be replaced by BTM Mainnet tokens.

Didn't happen with mine.

That was like 6 months ago.

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?

[karamanacar]

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?

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.

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?

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.

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.

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
