No, it's not if you know what you are doing.
All three hash boards have a separate power input.
You power one hash board and controller board with the first psu.
You power two hash boards with the second psu.

And it is not my recommendation.

This is my recommendation.
Just get rid of using the fucking 110V mains voltage and have an 220V outlet circuit installed.
And buy only one good PSU.
I did not say it was your recommendation, I saw it was Halong's. Yours makes much more sense though...

By the way, do you realise the fact that the Halong/MyRig 1600W power supply units do not work in the 110-120V mains voltage systems ?

Hagg, per the HM website in the FAQ's:

"Q. I have 110v supply at home, is this suitable?
A. Not really. Miners operate more efficiently with 220-240v and mining farms step down their own electricity supply to 220-240v. If you have 110v supply you will either need to purchase a 1600W PSU rated for 110v from an alternative source, use two of our 1600W PSUs for each miner, or arrange the voltage supply."

I bought 2 PSUs per miner (5 miners and 10 PSUs). Would 2 HM PSUs per miner do the trick?

Thank you! Smiley

If they say that two Halong Mining psus will do the job, then it should be ok.

I haven't seen the technical specifications label for the Halong Mining psu.
That's an odd recommendation. The power rails are connected between the chains so you'd end up having two PSUs connected to the one rail; most PSUs don't like you doing that to them...

ATTN: HalongMining.com Customers

Once again, Myrig will be providing the substitute PSU for customers from HalongMining.com.  Substitution list received and started to ship again and DHL notifications went out for today and it will continue to go out for another 1-3 days.

I pushed a more conservative firmware update this time with a slightly lower speed for balanced mode due to complaints of high power and fanspeeds from those entering summer, and more tightly controlled temperatures for optimal minimum fanspeed.

It should be version t1_20180512_024327 if you check for an update from the web interface.

just installed it, had to run 45min long autotune for balanced mode
seems to run fine now, i'll check on it in a few hours

I would like to buy a spare PSU. What are the specs of the PSU and where can I buy one? Halong should sell separate PSUs...
1680W 92% efficiency (220+V). MyRig are the ones who sell them.

For those keeping track of the latest firmware updates, I've pushed a slightly improved version which is designed to more reliably keep all chains up and running, and to fix a small timekeeping bug which sometimes showed the miners up for 100 days. The version number is t1_20180511_034450, just check for an update from the interface.

Everything was messed up after this firmware update.
I had to run autotune again

Edit: this firmware is bugged as hell. Even after autotune if you reboot, temps are going crazy 2cards at 79c while the other one at 50. fan at 100% in efficienty
had to rollback to 0506 to get back to normal
Thanks for the feedback. Will roll back and investigate.

Lucky if you have them replaced already.

As you see in my picture, there are now 2 miners running only with 2 hashboards at ~10 th/s.

So one more hashboard is dead.

Anyone knows if there is vacation or smth in china/japan? I dont receive answers anymore since 5 days Sad

It is not replaced yet. But Myrig is responding very well in regards to replacement. Will see what time is need to receive replace shipment.

BTW: I have another 2 dead hashboards since yesterday. I will be good in packing and shipping hashboards very soon.

GOOD IDEA!

@MyRig

You may want to consider starting a Thread in the Mining Support section, for all of the returns and replacement info to be found a little easier.  Wink

Evil beware: We have waffles!
that is the biggest knock against them.
and the question remains  why won't  more pools add it the software is not that hard.
I know the answer to that for most major pools.

My take is that being responsible pool operators, they need access to least one T1 - several would be ideal - to run the changes on Testnet before even thinking about applying the AB changes to a live pool. Have you offered one of your T1's for the operator of mmpool or other small pool to bang on? It certainly seems that Halong will not do it.

As Slush in 2016 and another pool last year found out, code needs to be tested hard by tossing a myrid of possible f*ups to the inputs using Testnet vs going live with apparently little to no testing of their code. Helps eliminate embarrassing 'oops. Sorry about that...' moments. Slush may have gotten away with losing a few hundred BTC in rewards because of a coding error that as a result lost several blocks with few screaming about it but that is NOT a good thing. We are after all talking about risking the pool properly generating BTC income and 'oops' is not allowed.

At least 1 user here will be providing Kano with access to a Dragonmint T1-- as soon as the person gets it from Halong that is. After Kano has a chance to implement and properly test the changes then Kano pool will support AB. As for the major pools -- ja, for obvious reasons I don't see them jumping on the AB bandwagon soon...

Hi,

you can expect even worse future. I bought 5 T1 and after 3 weeks of running them 4 dashboards are gone. In fact every week I have an issue and shipping wrong parts back. I was happy we have competitor of Bitmain....but it is long way for Halong to get there.

Be careful guys. These are very first parts are bad quality hash boards. At least in my case.

My dragons, running for 3 days now after the last firmware upgrade and set to 'performance':

http://fs5.directupload.net/images/180509/wmw6qb2c.jpg

One (dragon5) has a broken hashboard (only 2 out of 3 running)

However, not as expected..
