Topic: Reviewing the Halong Mining DragonMint T1, a 10nm Bitcoin Miner (Read 1942 times)
Here is detailed information: https://www.patliyo.com/borsada-t1-t2-nedir-aciklayici-anlatim/
The reference implementations for version rolling support are in the master ckpool code and slush's stratum pool code, so anyone running off those gets immediate support. However, if they're using forked versions or do not trust our code they will have to merge (or rewrite it) and verify it themselves. It is actually not a big change and easily emulated without actually using a T1 miner. However, given that about half the pools out there are owned by bitmain or a subsidiary of bitmain in disguise, can you not see a conflict of interest for them to provide asicboost support to their competitor until they decide to implement support for it in their own hardware?
Yeah I mentioned this somewhere else.
I am happy that f2pool has added it so the list is longer and some large pools as both f2pool and slush are big.
the 2 largest pools are bitmain based they will not add it.
but maybe viabtc.com would add it. or maybe BTC.top
The title of this thread needs to be changed from a "SHA 256 miner" to "Bitcoin miner" because it cannot do a single other sha 256 coin....
This is false advertising, just like Halong did.
This is false advertising, just like Halong did.
and you should delete this post as it is a lie
since bitminter has allowed merged mining with NMC

I think its not long now til they actually support it. Slush is gaining massive momentum

It isn't a question of compatibility with coins but whether mining pools choose to add a few lines of code to support it.
No, not that simple: It is a matter of the pool operators first having access to a miner to test the changes on their pool using Testnet .We are talking FINANCIAL software after all and all pools have their own tweaked hardware/software setups. Only a fool would make ANY changes without first testing the changes before taking it live.Halong of course has done NOTHING to aid that process so the pool operators need users to lend the miners to them. Once the users finally get their miners delivered that is...
I helped bitminter get the pool working with btc and nmc.
I even earned as we hit 1 block of nmc and btc.
I offered to help any pool with loan of a t1.
Only bitminter asked for me to point my machine to them.
We now have f2pool, ckpool , solo ckpool,slush,bitminter, Kano soon.

I've changed the title from "SHA 256" to "Bitcoin" Miner, as this forum is primarily about Bitcoin and I haven't heard much compatibility wise with regards to AsicBoost for other coins.
Thanks for your feedback!
It is merged mining NMC on Bitminter. It isn't a question of compatibility with coins but whether mining pools choose to add a few lines of code to support it.

Efficient mode settings I had fluctuating between 14.2-14.3TH, and drawing 5.3-5.4 amps -- 1272-1296 watts over the course of over a day.
That's between 88.95W/TH and 91.27W/TH, with a 90.11W/TH median at least on this boot and the beta firmware provided.

I'm pretty eager to see what type of specs this pushes out as the firmware is fine tuned.

Yeah safari is dying fuck apple.
I have to stop using it and move over about 100 passwords to chrome.
This software will be nice if I settle in with easy watts for pdu's 1400 watts or lower works really well
@xdrpx
The T1 board uses the exact same heatsinks as the s-9.
The board is a bit different in layout.
the efficient setting lowers fans to 60% in an 85 f garage
noise becomes okay.
still tuning,but this firmware looks like a winner for me on low hash setting.
It rocks at efficiency setting
13.85 -13.90
1325 watts

Never looked at the reviews of the s7 or s9 despite them being several years old now??
The t1 has same layout and lazy/brain-dead heatsink design that makes for them being LOUD due to all of the turbulence created by so many leading/trailing edges on that mass of individual sinks.
ref the Canaan Avalon repair guide for example of correct thermal design.

That's interesting, since you've mentioned about the S9. I went ahead and found HagssFIN's post on the guide / teardown but the PCB there wasn't visible since I guess the user wanted to retain the warranty seals. I went ahead and look it up on youtube and was amazed to see that it looks exactly similar to the Halong Mining DragonMint T1, including the outer casing.
Note: I tried googling the Canaan Avalong repair guide since the hyperlink you've provided is incomplete. I came up with https://bitcointalksearch.org/topic/reviewguide-avalonminer-841-130-ths-1290w-bitcoin-sha-256-asic-miner-3191702 and the technical setup page over here - https://canaan.io/faqs/avalonminer-721/page/2/ (for the Avalon 741 and 721). What's interesting was as compared to the Halong Mining dragonmint T1, the Avalon 841 has one continuous heatsink without many tiny ones attached to the PCB. Also, the 16nm ASIC chips right beneath them https://imgur.com/cYXplGP are clearly visible. Looks like an interesting design difference between the two.
I've always been a chrome man myself 
I just shifted my unit to efficiency too. It's autotuning, and I'll check back in the evening with results. Same pool target as my above test for anyone that wanted to track it live.

I have had some trouble getting it working.
Note to self stop using Apple safari
Works fine with Apple - Chrome- Yosemite.
I am tuning low power efficient setting with this miner
http://ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje
looks like power dropped at least 200 watts to 1400
still waiting on true hash rates but 1400 watts x 4 = 5600 watts which means it will be able to allow 4 units on a 30 amp pdu.
It would be nice to see it do 14250gh at 1400 watts

After about 3.5 hours of uptime on performance mode, the pool hashrate is 16.4-16.5T at the hourly indicator. Looks to be fluctuating between those numbers. GUI shows similar readings. Looks like my chain #1 is the performer, chain 2 has 22x the HW errors, and chain 3 has 11x. Had the other two chains performed like chain 1, it would be closer to 17TH!
Amp pull is between 6.8-6.9, that's about 1632-1656 watts.

With my preliminary testing, I highly recommend people upgrade to the firmware I've updated in the OP, I'll be putting these screenshots up there too.
I'll continue to test the other settings. Excited with this new firmware!

I set mine to balanced and I am waiting for results.

Good call! We'll be able to compare after a bit. I'm off to lunch now, will check how it's been when I am back, including what the power draw is. GUI 50 minutes in shows it averaging around 16-16.25 at least, poolside 1h appears to be catching up to that figure. Promising results so far.

Didn't get any DC readings off the first row of heatsinks. Will try to play around with it more after I play with the new beta firmware!

Had some nice high numbers on the wind up minute of hashing!

Pointed my T1 to ck's pool and it's currently running tuning on performance mode. Follow the T1's progress here:

Measure the DC voltage (if any) between the individual heat-sinks; while operating, but open, with additional external desktop fan providing additional cooling.
I'll try to accommodate this. Unit wasn't friendly with me when I had the fans disconnected or even connected, will try a workaround.
You can probe just a few random heat sinks while
all boards are normally mounted in the frame. If it
is anything else but 0V, we can run some calculations.
