Antminer D3 Blissz firmware (10/12 v1.12 update)

[dottat]

I would be down for a one time donation or a donation for each major version update for this.  The one thing I don't like too much is how slow it is to recover after switching pools.. plus you lose the work your machine was calculating when the timer dictates the jump to the dev pool.  I noticed after switching from the dev pool it took some considerable time to get back to serious hashing on my pool and when it did that every hour I had to roll back to the stock firmware because it was starting to have negative implications on my daily avg.  Enough it negated the power savings pretty quick. 

Would you be open to taking set fees instead?

I successfully modded the firmware...

I think you do not optimized compilation. Original file size is 761k and your is 2.8mb. hm...

Also vt200 and vt220 (\etc\terminfo\v\) is swapped (original and custom). Is it right?

Thank you for the information. Not top priority right now, but I will improve the compilation optimization later.

18/11 recommended UPDATE

https://mega.nz/#!Dp5HXBDI!KW1bMbljdTpuq_c4mOxAO6Sft7_-TMEXKn9bxk43Smw

Changes 18/11:
- fixes the pool priority, it will now mine on your own backup pools when your first pool goes down.
- Dev fee lowered to 1,5% (it was actually 1,66%)

Changes 17/11:
- fixes the high fan speed when switching to the dev pool and back to your main pool
- fixes the close PIC and need reboot!!! error on the original bitmain firmware
- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.


know issues:
when using the AUTO fan profile, the fan starts at a too high RPM after powering up.


Upcoming:
For the short term these are on the todo list for the upcoming versions:
- frequency and voltage per mining board
- faster work providing to hashing boards (should improve a little)
- auto restart option on low hashrate / xxxxx
- load balancing between pools support
- auto tune frequency / voltage
- profile support (low noise, normal, high performance mode)
- webinterface improvements

Someone please test the new firmware to see how it goes.

18/11 recommended UPDATE

Bitmain released a lot of D3 because of this dramatically increased the complexity of the dash. And as a result of very decreased profit from D3. So it will be a great demand to change the firmware for the D3 to get the other algorithms. If you manage to modify D3 to other algorithms - it will be good business.
I am willing to financially support such work. I think that a lot of D3 owners will join the buyers of such products.

First!
Thanks for very very good work.

I don´t know where is your problem guys, you maximize your profit but won`t pay a little fee for it?
Claymore and miner other miners do same and everybody use it! 

[gunmunj]

I think this type updates very good for efficiency but warranty is important subject. You have to becareful 

[Sadd3miner]

Im 100% willing to pay 1.5% fees, this is blissz hard work after days of struggle.
Bitmain left D3 buyer behind, HE is the one got our back to lower the voltage for profit, he can keep it for himself. But no, he decide to share it.

Thx, a lot.

[Pedrojok]

I have to upgrade the firmware twice a day to keep up with all your release !!! 

I'm impressed. I no longer hear my D3, it doesn't get as hot, and it is much more efficient. I don't have a watt meter, but I get pretty stable result with:
- Lowest voltage
- 438 freq
- 15,7MH/s average
- auto fan speed 3,060 / 3,120
- Temp chip: 69 / 70 / 72

I guess it should draw about 763watt as lucasilverio stated a few post before (running at same frequency). Only a couple of HW. Have got the 01-15 nov batch (19,3GH/s).

Just one thing to add: THANKS A LOT blissz !!!

[cougarcxt]

this is awesome work Blissz,

thanks for all your efforts.

any chance you'll be doing a similar firmware update for an S9?

cheers

[nwfella]

Just tried giving custom firmware a shot with various settings and sadly unit stopped hashing after only a couple of minutes.  Will give it another crack here hopefully sometime later today.

[cryptonitro]

i restart few time , at same frequency same board has ssometimes lot of error , in other time no and it it an other board .?.. make no sense.
curious to see with mhz per board results

@cougarcxt : time is for D3 actually , i will have one s9 to soon , and for sure i would love to find the way like blissz did , only for fans trick

[dashcoin1]

It's working,thank you

Still trying to figure out the value of this firmware upgrade
at stock settings I'm getting 18.9 gHz fans @ 2580 and 3390.
so it's less noisy  and generates less profit.
plus I have to pay dev fee 1.5%.
When I undervoltage even less profit and HW errors
I have a watt meter coming in soon I will keep you updated if it's worth it.....
I'm not trying to be negative here but these are my observations so far .
I will post again with energy usage

yeah...I'm in the same boat ..this is a great thread to lurk on and learn about this stuff....and kudos to those experimenting

but unless some kinda of algo besides x11 rises out of this project....well, it's kinda moot at the currently x11 difficulty rate

but sure, if you could mine the other algo's you'd get some significant firmware cash..but my take is...if it could have been done easy

Bitmain would have already milked this cow....


(not to say, when I'm with my D3's in the gutter of x11 mining, I may need this less voltage solution....crawling around for some reason to run them

...but alas, that is the asic addiction talking....) unless other algo's in a month or less, they will be 'un-runable' like the old BFL ASIC miners or USB miners

it just won't make any sense...thus doorstops I'm afraid

hope I am utterly incorrect thou....(ego protection don't ya know, preparing for the worse)

HW errors @ 18/11 stock settings , going back to bitmain firmware

...

Hi guys, I guess you're all having the same issue:

Here are some starting points:

for silence and best efficiency / miner lifetime

Expected hashrate: 15Mh/s to 17 Mh/s (my personal preference)
Expected power usage: 700 - 780 watt

set the frequency at "400mhz", set the voltage to "lowest". Now slowly increase the frequency until you see HW errors. When you have a few HW errors an hour you found the sweet spot
set the fan speed manual somewhere between 20 - 30 percent. Chip temp should be somewhere between 75 - 80 degrees max.

For stock performance at lowest possible power usage

Expected hashrate: 18-5Mh/s to 19Mh/s
Expected power usage: 950 - 1100 watt

set the fan speed manual to 50% (adjust this later to your needs. Max chip temp should be 85 deg)
set the frequency at "525mhz", set the voltage to "15". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

For Extreme performance (this is not recommended for 24/7 usage)

Expected hashrate: 21Mh/s
Expected power usage: 1300 - 1400 watt

set the fan speed manual to 100% (adjust this later to your needs. Max chip temp should be 85 deg)
set the frequency at "600mhz", set the voltage to "20". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

In summary,
No one care fan speed , voltage etc unless additional algo
Because most of us will shut it down if no profit as is now..
I am asking all legendary , full members
Please reach the related senior develeopers
I am also wrote  to cgminer( not interested)  developer and gentarkin ( not replied  yet)

But I am newbie finally.
 I dont recognise all develepers who are capable of.
This will not easy even it is posssible.
Possibly more support needed , probably  a team work is a must.

No one say this is( new algo ) is possible including  Blissz actually.

I have highly   lost  my hopes

I agree that a new algo would be awesome and I will look into that more once this x11 version is finalized, but in the meantime for most of us it really does help if you can run it at a lower wattage. Especially when you run it at home.
Why this does help:

- significant less power costs with just a slight drop in hashrate: ~19 Mh/s @ 1200watt vs ~17 Mh/s at 750 watts.
- more profits as the power costs dropped that much. Especially true if you run it in Europe
- less heat
- way less noise (2500 RPM should be sufficient)
- one other thing: the total difficulty will drop a bit if the majority of the users run it at a lower hashrate, so in the end it means that you get the same amount of DASH with a lower power bill.

just my 2cents
