[Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions

[mxnsch]

Then your hardware is broken i guess. It does not have to be the blades, could also be the Raspberry Pi (mini computer) or the controller board that is broken. Heck, it could even be a broken PSU. I have also seen broken connectors that needed to be resoldered. I guess it would be best if you open up a new thread where we can discuss your hardware issues.

As quiet as it can be. My gaming PC is louder 

Sorry to bother you again with this non-so-relevant issue, I just found that I bought the non-PWM version of these fans, while the ones in your link have PWM.
Do you think that it will affect the noise? As far as you know, is there any kind of PWM support in the board, or they will just work the same? Or the support is not even needed?

ah well fuck it then, just gonna throw it out. would proberly be a waste of time and money to fix it

thanks tho, just had hopes for the firmware would solve it

I have an issue when setting up Stratum proxy - after all the steps and the last "shutdown -r now"
Cgminer fails to start up :

as you can see - it's stuck on ./superrun
if I manually run superrun.sh i get :

root@dragonminer:/var/www# ./superrun.sh
root@dragonminer:/var/www# ok,we are daemon now.
no key hook
no key hook
no key hook
no key hook
no key hook
no key hook
no key hook

which then never ends (and cgminer never starts)
running ./run.sh also never actually starts cgminer.

comment out  the options in /etc/rc.local.real - and we are back to normal mining.

is the 8 gb version ready ?

[BannedDK]

is the 8 gb version ready ?

think its the one on page 1

[roderick112]

man you are amazing!  

it does not work in a raspberry pi b+   but in the 1 you get with it it does!

only running 2 asic the psu 1200W psu died ;/ so put a 600w in for now

Regards Roderick!

@biomatrix
sorry, i somehow missed your comment! Can you please PM me in case you still have this problem?

@yslyung
The 8 GB version is up for a couple of days now. In fact as some already noted, it will even work for 4 GB cards. If anyone needs the full 8 GB, the partition ca be expanded while the miner is running.

@roderick112
I tested it with a Pi 1 and Pi Zero and that worked. What happened when you tried in a B+? It should just work, but it might miss a kernel module for the controller board. If you really care, we can investigate and surely resolve this.

its not a problem was just testing the miner really does work great now! thanks again for the proxy! helps alot

Glad i could help! I think that's part of the game and gives new contacts all around the world for years now. Bitcoin is definitely not only about money, at least for me.

I was also amazed how much more stable and effective these devices can be, only with software tweaking.

Best wishes

P.S. Added the downloads for the original firmware files in the first post (all devices)

I will PM you about this later - I must be missing something - it's been a while since I setup a SP.

also, to anyone...

I'm new to this device.... what do these #'s mean.... and how do I resolve them?

TY got a nice OC with

volt 650
and clock 1100

Looks like a sweet spot 

[cero9]

There's one thing I don't fully understand:

On this firmware (like on the stock one), there's space for three pools.
I don't understand if the hash power is split between those pools or if the second and the third are used as fallback.

Does someone know that?

Fallback if you dont use stratum proxy from first to third one. Stratum proxy implements other strategies, too.

Thank you, got it!

The stock fans are horrible! I replaced the fans with 4 spare arctic fans i had spare.
http://www.memoryexpress.com/Products/MX49912
Hope that helps! Got it down to 35dB.

Ps.: A new 8GB Image is ready, but i am on the road and will upload tonight.

Sorry to bother you again this issue, but the miner only has two fans. The other two are referred to the PSU?
Did you also replace them? Or did you made some mod to the case?

How do I check temperature? I see that voice on the log table, but it's empty

No need for excuses, glad when i can help. The controller board has sockets for up to three fans.

To use more than three fans, you have to use a splitter like this:

How do I check temperature? I see that voice on the log table, but it's empty

As far as i can remember, the default view in "miner.php" does not display the temp correctly. You can switch to either 'Kano' or (afaik)  'Mobile' view.

Yes I found that, I was just asking "where" did you set up those fans?
I mean, I replaced the two that were already there with these new fans, but the other two? In series? Did you cut new holes?

About the temperature, still no way.
Even in the mobile view, the temperature column is just empty.

This also happened on the official firmware

[cero9]

I also tried to undervolting hoping to save some energy and, mainly, to keep temperatures a bit lower.
Do you think it might work? It says that the minimum voltage is 600 (which is? 6V?), I put 580 but I'm not sure it's applying.

I tried with 500 but only two of the four cards were running, so I guess it works, but if so, I don't understand that text.

[mxnsch]

Haha, now i got you. I fixed (with Sugru) the additional two fans on the back to assist the front ones with blowing hot air out of the case.
