New Dragonmint B52 miner from Halong

[philipma1957]

Forgot to mod the thread so I made this one old thread is here

https://bitcointalk.org/index.php?topic=3338355.0

I got one of these  a week ago

https://halongmining.com/shop/dragonmint-b52-blake2b-miner/

Sold out right now


It is mining Sia coin

at siamining.com
and sometimes nicehash.com

It is a mofo beast

4.20th!

I want to moderate thread.

[philipma1957]

So 4.20th is higher then the  spec of 3.85th

 How are  the fans  the temps and the watts?

its just showing in the webinterface, on siamining average hashrate is 3.77 GH/s for me

@ yankees  this miner has one speed setting full speed ahead.

The Dragonmint T1  has firmware upgrades from-ck

slow        = Efficiency
medium  =  Balanced
fast        =  Preformance.

The B52 does not have the  firmware upgrade for that.

So it just goes fast.

This makes it loud and it uses about 1475 watts  on a Myrig psu.
But it earns  good money.

-ck told me that a firmware upgrade may be coming for it.

he does not do alt coin software  but he believes  Halong can adapt his firmware without him.

For now  this miner is earning me  3200 sia a day on  siamining

that is 3200 x 0.00000227 = 0.007264 btc a day  or $58.85 usd a day

power of 1500 = 36 kwatts or  3.60 usd a day at 10 cents

$58.85 - $3.60 =  55.25 a day.

that would be 30 x 55.25 = 1657 usd a month




@ vinci  it varies on both  nicehash and on siamining

it gets up to 4.2 and down to 3.6 on siamining

it goes from 2.5 to 5.5 on nicehash.

Phil  nicehash has almost  no hashrate.

Can't you get burned  if the leader stops renting?

Sure here is the current setup.

two guys are on the usa side.

my miner is pointed to usa.

If the top two guys leave I have to switch to siamining.com or lose money

4.20th!

how much did you pay for it?

I will be downloading first of multiple videos on this unit. youtube.

Buysolar my partner in mining  has the antminer A3

HE GETS 800-900GH  WITH 1000-1100 WATTS

THE B52 GETS 3.8-4.2 TH WITH 1475 WATTS

This is total destruction of bitmain.  This has not been done to bitmain until now.

I am thinking this means a shift in the world of crypto such as we have never seen.

1100/900 =  1.2 watts a gh


1475/4000 =  0.368 watts a gh

This is total destruction of bitmain.  This has not been done to bitmain until now.

it about time. But Bitmain money maker is the Bitcoin ASIC's and they have not released any new ASIC for that in 2 years.  Most likely they are have been working hard on it but has not released it as there is no reason. Same as Nvidia doesn't need to release any new gaming cards until they have to. But once something comes on the market Bitmain will respond in a few months with a much better miner.

[philipma1957]

at Etherion well I agree pitman is a very powerful company in this game.


But bitmain mocked this company when it first came out  can't find it but it was insulting the Drgaonmint name. I wonder if they knew that these miners would be really good.

here is the stats page from siamining

you can see  the april 16 to 17 numbers pool side  where over and under 4th like 3.75th to 4.20th

Your video will be live at: https://youtu.be/Sbh213G2cbs

video will be up in a few minutes

I am using a MyRig psu and 240 volts power

[generalt]

Interesting.  So the B52 works on nicehash?  Maybe I heard wrong but I thought that I read that the Bitmain A3 didn't work on nicehash not that it really matters since there's only one coin to mine.

and the b52 appears to be innosiliicon s11

https://halongmining.com/shop/dragonmint-b52-blake2b-miner/

This is a case of how fast do you get it.

Since at 3500 cost  and 50 a day after power that is a 70 day roi

7 x 16 = 112 th that is 7x T1

 116 th is 62usd a day  before power but 7 x 1500 = 10500 watts  which is 252 kwatts a day so at 4 cent power that is 10 bucks

so one of these right now earns better then 7x T1's since most of us don't have that power price.

[philipma1957]

Okay this miner  would run a bit hot and fans were always maxed.

shit no name fans

Model: KBE-FAN -12038M

12 VOLT 3.9A

KBE

So I got some  

SAN ACE
Model 9GV1212P1J091
12 VOLT 3 AMP

 right off the bat power use dropped 25 watts

and temps are now

---------------------------------------------------Temperature
1   1.42 TH/s   Alive   23712/0   1027---   61℃-74℃-85 ℃

3   1.42 TH/s   Alive   24007/0   1157---   55℃-71℃-83 ℃


Wires  needed to be switched I will photo

I paid less from this seller on eBay

you need to switch the blue and yellow wires or it runs wrong.

oem correct wire order

san ace wrong order
https://i.imgur.com/fjlbyuY.jpg   full size






two fans side by side the san ace is  quieter

[TheYankeesWin!]

That seller is asking a lot for those fans phil.

[philipma1957]

Yeah they are about 50 for a pair  after shipping he raised price.

I got 4 for 91 and earned 7 in ebucks  so I got them at 4 for 84 or 21 each.

But the B52  earns 50 a day   so a dead fan  means I lose 50 a day.

I now have spares.

Also  I am cooler 3-4c
I am quieter  3 db
I use 50 less watts

that is 1200 watts a day  or about 14 cents a day  so in 300 days that is 42 bucks. which is what 1 pair cost.

What were your temps before swapping the fans? Only thing I see is from your screenshot of the webpage, which shows 85/85/86 for the max temperatures.

Beside the power save, did the sanyo denki make any difference temp wise? I notice the miner shuts down if max temp touches 99 or 100.

Across several b52s, I'm already close at 96 on one and 94 on other two. Looking to sort out these fans before summer.

I upgraded firmware for B52 and temps go down. But my new problem is autotuning never stops.

same problem

[Devilpit]

Does anyone else have fans alway at 100%? My auto tune is stuck also. I’m probably going to downgrade the firmware.

[SamX76]

Bad software, and bad chip organization.     Maybe these fans will be better:  The Original Delta 12cm 120MM PWM FAN 252CMF 12V 3.9A TFC1212DE .    I will try   .   SAN ACE Model 9GV1212P1J091 12 VOLT 3 AMP have only  224 cmf

[guzzler]

Anyone has the original firmware? I updated it to the latest and my hashrate is down to 3T. I would like to flash it back to the original firmware. Let me know if you have it. Thanks.

I'm having the same issue.  My GUI says 4.25TH but Siamining is telling me 2.9-3.2TH.  Autotuning never stops.  I can't imagine it runs at the correct hashrate if it's always in tuning mode the whole time, maybe I'm wrong.

To clarify, I'm using the S11 from Innosilicon but I'm pretty sure that doesn't mean anything since it uses the Dragonmint firmware.

[Devilpit]

Here’s the original firmware
https://download.halongmining.com/files/b52/b52_20180331_123525.swu
Hash rate is much better pool side but still runs hot as hell.

the fan swap did help me a little.  3-5c

anyone pointing to nicehash?

[Devilpit]

Use the new S11 firmware from innosilicon. I get average 4.2 gh on siamining for 24 hours. It still runs hot and fans remain at 100% but the hashrate is so much better on pool.

[paddyj]

I can confirm, not that it matters. The S11 Firmware from Innosilicon works on the DragonMint B52 and appears to provide a noticeable increase in the poolside hashrate. It also doesn't get stuck in auto-tune so you can crank up to performance mode if you want.
