Saw something that doesn’t match bitmain’s story about the amount of B3’s they sold in Bstch 1
http://miningpoolstats.stream/bytom

It’s on 7700 clients now while a few (including me) still need to receive their Batch 1 B3.

I'm not sure how they calculate the number of clients, but could that include people trying to mine with GPUs and CPUs? CPUs are probably pointless, but people are saying on the discord that while GPUs are less efficient, they aren't useless, although they get a larger share of rejected shares.

2) Rejected share rates seem to be very high. Roughly 45% in my case. It doesn’t appear that my profitability has been affected at the pool, but I’d like some anecdotal feedback that others are seeing the same reject rates.

I'm having similar reject rate. Still showing ~700-800 H/s poolside so I'm not worried.

No Air Cond. My Basement is little cold still and that may be the reason and my chip temperature was always 30-35 degree before I removed the fan connector...but still 40-50 is still OK. All i am saying is just remove the exhaust fan connector and just try it for an hour...I see people are struggling so much to change the config or change the fans....Which I am saying is not required. Note the current chip temperature....switch off the miner...remove the exhaust fan connector...switch the machine ON and try for an hour....Just giving my experience and noise level is way far better....

I've been running it without the exhaust fan for ~24 hours, no problems, ~5 degrees hotter than before.

Cool..!!!! this confirms that is there only ~5 degree difference...Guys, whoever can remove the exhaust fan can remove and try....whoever doesn't want to remove the fans...just remove the exhaust fan connector and run the miner....You will be happy with the noise level...hope someone can sleep happily

I tried, it does not work on the B3. Both fans still at max speed.

Tried this:

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"

and

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50",

I thought a comma , was missing behind the "50" but no change ...

Guys, All I did was just remove the connector of the Exhaust fan. My chips temperature is at 35 degree and I still feel cold air coming out through the exhaust fan(I did not unmounted the fan from Miner) one fan is enough and the Noise is almost 50% less and I am happy that no disturbance from miner

That cant be right. Some of us use both fans and it is 40-50 degrees as seen in above picture. U must be in a cold place?
U have cold air due to air-con?

All,
Curious to know if anyone else is seeing the same behaviors as me.

1) No matter the pool configuration order, 0 and 2 are always marked dead.
Bmminer always chooses pool priority 1, regardless of the port.
Same behavior for 443, 6666 and 25.

2) Rejected share rates seem to be very high. Roughly 45% in my case. It doesn’t appear that my profitability has been affected at the pool, but I’d like some anecdotal feedback that others are seeing the same reject rates.

Does anyone know if these are all getwork ports at the moment?
The only pool source released by BYTOM is getwork-based, and no formal stratum protocol reference has been published.
I suspect Antpool plans on deprecating GETWORK support on ports 6666 and 443.

All pools have been active for me since I plugged them in yesterday.

B3 is for mining Bytom, an cryptocurrency which uses AI algorithm as its base.
Bitmain and Bytom have been working together to release this rig.

Bytom:

Tensority:

very interesting to bytom community

It is probably best not to mess with the fans. The S9 can handle over 100 degrees while the L3+ is max at 80. We dont know how much this one can handle and for how long. It is best to just leave the fan as it is. Notice that miners which use more electricity can handle higher temps. Those waiting for the miners should prepare a noisy place or one of those thick boxes to quieten them some.

It s not working, so he didn t tried it.

If someone have a REAL solution to control the fans ...

You can adjust the fan speeds by editing the file /config/bmminer.conf and adding these lines:

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"

That adjusts it to 50 percent the default speed

Here is the whole bracket in my current config:

}
]
,
"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-use-vil" : true,
"bitmain-freq" : "_ant_voltage=0706",
"bitmain-voltage" : "0706",
"multi-version" : "1",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"
}

did you tried it?

I just unplugged the exhaust fan to reduce the noise. Temperatures went up by ~5 degrees. I think it will survive that. Will try the config change later.

I think they are actually under-engineered, they may have not added kernel modules for fan speed control, which means there is no way to change it. I am very familiar with openwrt because I work with it every day and I have been looking through the filesystem. I wish I had access to the source code so I could compile something better. I have a lot of features i could add. I've been looking.

"multi-version" : "1",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"
}

My only concern with this, is any potential reason Bitmain shipped them without PWM control enabled. It’s clear that there shouldn’t be a need for this volume of air when dissipating 330W, but I’d be curious to see if the rejected share rate gets higher as the temperatures creep closer to 70+

(I don’t think BMMiner is reading HW errors in the traditional sense in this Tensority build.)

The miner seems overengineered.
Has anyone tried pushing the ASICs past 750 yet?
(The default config shows “bitmain-freq" : "750" in bmminer.conf.factory)

Either there’s headroom both ways, or the blocks on these ASICs start to bug out at higher frequencies/temperatures.

Who’s willing to figure out? Grin

PS - Anyone else get shipping confirmation for batch 2? Seems early...

Can you better explain how to edit the config file ?

The 100% fan noise makes me mad.

Guys if i mine via Antpool and provided Hitbtc wallet address. Will the payment be proceeded to hitbtc exchange platform and will i be able to exchange coin? Thanks in advance

Does your BTM address at hitbtc start with 0x? If yes then yes your coins will deposited to the exchange without any problems. Make sure to keep track of your address on the exchange as it might change.

I can see that my Bibox has the 0x adress aswell but my wallet on my computer has the bm1 so the 0x is the ERC20 people are talking about?

And if i deposit my bytom to my software wallet on my computer i will not be able to exchange it? (yet)
Is Antpool paying out in the old tokens cause the already own them and are making money out of it?
Should i then go for UUpool instead and just pay it to my software wallet and wait for trading sites to change to the new net.

I mean im not in a hurry to trade the bytom i just want to accumulate an decent amount.

Correct. Bytom can only be mined on the mainnet (Bytom wallet address) and every pool should give payouts on the mainnet, however, Antpool is doing something different. They mine on the mainnet and give you an ERC20 BTM. So they're basically paying you out of their pocket and keeping the mined token (the ones on the mainnet). Weird but good at the same time if you need your investment back ASAP.
