Hi Blissz, I'm using your firmware. My Fre is now 494, Voltage is 8. My hashrate ~ 18300.
0 HW
But after a while, I got Accepted 167, Discarded 289 which is high, I guess. Does anybody know why?
Thanks

Change to different pools.
I search info about "Discarded" and found it:
Quote
"Discarded is a meaningless stat unless you're using getwork (and even then it only matters to the pool operator, not the miner). It is a 100% useless stat on GBT and Stratum. Discards are not rejects, they aren't even shares. It means your software had work prepared to hash but instead it discarded it in favor of newer/fresher work. You aren't wasting any hashes when your miner discards work."
Quoted from eleuthria, former BTC Guild Pool operator.

Changes 26/11:
- Solved an issue where loosing your network connection for a longer period could burn out your hashing boards as the fans run at a very low RPM.


That is just bad. The stock firmware had protection for that.

I'm using nicehash Sad Can you suggest me some good pools to try? Thanks.

I had sent you an message of my current pools. if things are not looking good with "rejected" or "discarded", ask other experts  Smiley. Did you download the latest FW?

Blissz, auto reboot on low hashrates, is it working?

Performing it is a better way of learning things
Blissz,

I manually restarted the miner, the chain 2 status changed to  oooo, but the hardware error keep coming, and the hashrate stayed at 0.  This caused the miner keep restarting itself non stop, while the chain 2 status kept at ooo but the  hashrate kept at 0.   It is worse than no restarting.   Can you have a setting to stop the restart?  ateast the miner can mining with 2 chain?

Thanks

Confirm,  the D3 does not re-start with one board error out:

Blissz,

How did you do with the wires of new fans? I saw pictures of it and it has 3 wires vs 4 of the original fan, I am really interested in changing those crappy fans.

Thank you for the fan fix blissz, couldn't replicate the problem, but had a feeling it had to do with when there's a network interruption, much relieved it's fixed.  Had chips go to 114 degrees on one machine before I noticed and quickly intervened.  Error rate was higher than normal after that on that machine even after restarting, but after a short cooldown period they are working perfectly again, guess I dodged a bullet.

Also received my end Nov batch d3 and the fans on this model is of a poorer quality, different model, lower amp and much louder than the fans on other batches, a shame since my other d3's were all much quieter with the custom firmware and now the new machine just tops out the overall noise level again.

Good to hear your d3 is fine!  Grin

You can replace the fans with some other models. I actually run mine now with two Scythe Slip Stream Slim 2000rpm, 120mm. This is of course not the solution if you want to run at high hashrates, but for the lowest voltage setting and 15 to 16 Mh/s this is a real nice and quiet fan.
I also modded the PSU: I added a small fan controller to have it run at half the RPM. Now this combination is actually really silent. I can have it run it in my living room if I want to.

bch will go 2400 dont buy d3 now

Do you have any new D3 you don't need? I will buy $600 each or $750 each plus the PSU.

Hey Blissz, is the feature "Automatic reboot on low hashrate detection" working on your latest FW?

Flashed new firmware this morning.

Machine 1 running 2 boards went from 10.7 to 11.3. Watts didn't change.

Machinen 2 running all three boards went from 16 to 16.8. Havent tested the watts yet.


That's looking good!  Grin

***************Well it lasted an hour and then the same board crapped out.****************
It ran the entire time without an error. Just hit the refresh button and 60+ in last few minutes and board that one board stopped


Ok so I don't know if its juat another day or the new firmware.

I put the bad board back in after the new update. I now have Machine 1 up and running for about 20 minutes and no HW on the "bad" board.


I'm running at 15.3

The bad board is clocked down to 350 and I have to use 10v. But at least its providng 4000+.


Not sure I feel safe leaving it unattended. Not because it will burn out but when the board fails it still sends power to the board and its just a waste.


Blissz can you shed some light? these boards do seem to be tempermental day to day.


I do think you're unlucky with that board and have to RMA it. If it doesn't run stable at 350 Mhz it's just broken...

A great feature that would be really helpful is different power profiles. So you can run quiet when your home or let it rip while you're away with just one click as apposed to having to change each board individually.

Would make it easy so you didn't have to remember the settings for each board in each machine.

Yep that's something on my wish list as well Smiley

Blissz,

From the log, it looks like you set the internet/pool available watchdog timer to 120 seconds (which is too sensitive I think).  However the internet recovers after 135 seconds.  I would suggest you extend the timer to 180 seconds or so,  or make it configurable

Thanks

I will make it configurable, as it really depends on your needs. The behavior from your log seems fine by the way

The download link is dead

ya i found this https://www.3m.com/3M/en_US/novec-us/applications/immersion-cooling/

any one know how to get that stuff or where to get , thanks  may142012 for the word to search for

Sent you the link of the fluid to your inbox.

From what i know, you need a big tank that fits all of the boards from your miner, a top tank that install the Cooling Coil to do two-phase operation, and of course the 1 gallon fluid that cost $300.

Off topic, but only slightly considering Blissz originally set out to make a silent machine...

That is the fancy 3M Engineered Fluids method... the hippy non-toxic way is to just use mineral-oil or some other suitable dielectic blend.  About 90$ for 5gallons.  Less in quantity.

Note, there are some serious hippies out there too!  Not just over-clocking gamers up for a laugh.

Note one of GRCs products is a "hash-tank" comprised of S9s up to 5800Th/s squeezed into a 40' shipping container.
https://www.grcooling.com/bitcoin/

The tricky bits are circulation and heat exchanging... but not problems that haven't been solved a million different ways before.  I'm leaning towards trying a recirculating pump and a automotive transmission oil cooler+fan outside for my baby farm (two D3s)!   If I lived in a colder climate I would consider a classic household radiator and dump the heat inside seasonally.  If that can't move enough heat I'll have to try to build a evaporative cooler and heat exchange with water.

Take a journey down the antminer immersion cooling youtube rabit hole:
https://www.youtube.com/results?search_query=Antminer+mineral+oil

You mean like this guy doing? https://www.youtube.com/watch?v=HcBTYOOXX2o

That is alot of Novec fluid, maybe 2-3 gallons! (the cost of a D3).  Fans and heatsinks aren't necessary in a Novec closed loop system, i've seen better where the hash boards just lie flat on an aquarium bottom and maybe only 1/2 gal of fluid is needed.  In closed loop you still have to cool the condensing surface somehow.   Probably less efficient but a peltier cooler strapped to a large heatsink or plate might be less messy.  Not for dash, those things are energy hogs, perhaps workable on another coin, or if the one cooler rig is all you need for lots of hashing boards.

My exchanger/condenser thoughts lean towards a wort-chiller rig or plate heat exchanger with a DIY cooling tower outside to cycle the water.  But my first attempt will be to just pump and exhaust the oil heat directly.  Pumping water is better, as you are't restricted to the types of pumps that will do the job and not break down, but I think the small food-grade pumps can handle oil and are pretty cheap.  If you are after parts for your rig the automotive and home-brew industry seems to be a good resource.
