Dayun Zig Z1 - Lyra2Rev2 6.8GH/s Asic miner

[sysubeing]

What did you pay for it?  One of my suppliers in China quoted $4600 (this is just the machine, no shipping, psu, etc)...

It looks interesting, but isn't Vert and Mona supposed to be switching to a new algo in Q1?  My supplier also said this is going to be the only production run of these devices (due to this) - which could be a good or bad thing, depending on how you look at it...

The manufacture is a bullshit! They said this is the only batch of 2400 miners in oder to assure the first batch miner's profit.
But they just released a new version miner of 7.2 GH/s.

[0305rig]

Just received the Z1. Got it connected to network. Put the IP4 to static.

Tried to setup with different pools. But no luck, it stays offline.

When I go to Dashboard Widget, it says - THE MINER MAY NOT BOOT.

Anyone has an idea how to fix this?

Try NH or MPH, if those work then the Z1 is not compatible with that pool

[roberto_f]

here is my feedback.

got the miner 3 days ago

to make it go online had to change the ip to .10 instead of .100 and put manually DNS server name

then tried different pools. nicehash, MPH, powermining. all same performance, 1 board not hashing fine.

changing frequency doesn't seem to do a big deal, with 900 one board stays dead all the time, with 800 dies after a while.

sent message to crypto drilling (shop I bought) and told me to freq 845 (which I can only put 850)

How did you get the extra fan controls?

[sysubeing]

Dayun Miner is the new name for PinIdea. It is evident just from the design and build quality of the miner - which is very good, I might add.

Can somebody get a full raw image of the USB key (dd clone) instead of just the files?

source that PinIdea = Dayun?

yes, I found that from one of config files

[Bitreo]

if you want to modify the config files on the filesystem then you need to get the root password. if anyone can crack the password here is the hash :


Username: root
PW Hash: $6$pvnavTv2$2W/s.veJLVbb1g9qJpFO7ATNNBiOtwt.MXABU6nRVgJwuiS3WlBrRMj0avAdnHL

regards

hash for root not full specified.

Here is the correct:

Code:

[sysubeing]

You guys got any solutions to control the fan speed? I live in an apartment complex and you can hear it in the hallway a door down lol. I'm bound to get a noise complaint from the police soon. It's annoying cuz the mines are running at 37C so plenty of leeway to run slower.

Take-off outtake fan. And plug a simulator that fools the miner.

The Z1's seems to send a lot of stale shares(these are being shown as rejects on powermining pool, and seems to be doing the same on nicehash i see). That is software related issue, so i hope they will supply an update soon to fix this.

Hard to see your image https://www.screencast.com/t/8cvezEcAnD, but seems like lots of chips that does not work? If so, try to reduce frequency slightly.. You won`t get advertised hashrate, but maybe some more than now if those chips becomes active again. You would probably have to return the faulty hashing board

[0305rig]

Thank you code3gen.

Got it to hash Power Mining pool with right Wallet.

I had to put it on DHCP to get it permanently online.

The zig z1 hashes less then advertise and seems to be unstable. % of rejected shares is high (10 to 15%).

So when they ship this units do they ship to your house or do you have to go pick it up somewhere? What's the process?

[sysubeing]

"lyra2rev2-asic-x": "4",
"lyra2rev2-asic-y": "24",
"lyra2rev2-asic-num": "50",

I suppose "asic-x" = 4 means there are 4 hash-boards, "asic-y" = 24 means there are 24 chips in each has-board.
So does anyone know the meaning of "asic-num" =50?
I tried a value of 80 and ran for 12 hours. The hashrate still not stable, but no offline. Need more time to test.

Hello guys,

i want to purchase the asic with the lyra2rev2 algo.

Is it real?

I read there are a lot of asics which are broken and cannot be repaired because the website of Dayun is offline.

Is this asic reliable, or do we have to wait for bitmain to produce and sell a lyra2rev2 asic?

I have purchased some z9 minis and z9 but eventually after 3 months from the first batch i feel getting fked because of the low roi now.

Anyone have some ideas it will happen to the dayun zig z1 too the low roi after some short time?

like to hear some suggestions and ideas from you guys.

I quote a comment from an Chinese reseller >_<
因为前些天发了关于dayun zig z1矿机的广告，最近加微信咨询的客户挺多，相信大多数投资者是冲着z1矿机宣传的高收益来咨询的，通过这几天市场反馈来看，我个人觉得有必要提醒下广大投资者，暂定这款dayun zig z1矿机是不太靠谱的，很多人说这是rr210矿机的前身，而且是组装机；rr210相信大多数今年老矿工知道，rr210矿机刚出来的时候售价2万多，一天利润200多，但是后面没保持多久收益每天乘递减式 ，割了很多矿工的韭菜，这款z1矿机刚出来的时候收益宣传差不多有100美元，也就是差不多600rmb，客户挖了两天实测从400多跌到现在只有300多收益了，另外就是售价方面，第一批刚出来的市场价在50000多，任何一款新矿机上市尤其是挖 小币种矿机的，市场价格都存在虚高情况，所以那时候我建议我的客户再观望下，果然第二天就跌到了3万多，价格和收益及其不稳定，另外有客户说他花50000多买的第一批矿机就坏了，现在售后情况未知，所以dayun zig z1矿机购买的风险大家还是要注意下的。更多实际情况可以加我微信探讨！

then tried different pools. nicehash, MPH, powermining. all same performance, 1 board not hashing fine.

changing frequency doesn't seem to do a big deal, with 900 one board stays dead all the time, with 800 dies after a while.

sent message to crypto drilling (shop I bought) and told me to freq 845 (which I can only put 850)

waiting for their technical team to reply..

this is my configuration

and this is the results



hash rate quite erratic but never higher than 5GH

any feedback or suggestion, very welcome

How did you get the extra fan controls?

Hy btc2017btc2017

There is no fan control for this miner.
To see those "controls" for the fan, you need to activet the option "Auto Stop Miner".
But there you can only tell the miner to stop working if the fans turn lower then the value you set.

here is my feedback.

got the miner 3 days ago

to make it go online had to change the ip to .10 instead of .100 and put manually DNS server name

then tried different pools. nicehash, MPH, powermining. all same performance, 1 board not hashing fine.

changing frequency doesn't seem to do a big deal, with 900 one board stays dead all the time, with 800 dies after a while.

Hello Roberto_F

About the non active chips you have on the "ASIC Status" page.
Here is what i do when i have the same problem (Status black, yellow or red)

Go on the Settings page and just hit the "Save and Restart Miner" button.
Check after 2-3 mins on the  "ASIC Status" page if its better. If not...hit that "Save and Restart Miner" button again.
Again, go check after 2-3 mins on the "ASIC Status" page if its better. If not, try this tome the "Save and Restart Machine" button.
Now wait 5mins and then check the "ASIC Status" page. If its's better...good, if not, pull the plug from the PSU and wait 10-15min.

Pull the plug back in and wait...
Again, check the "ASIC Status" page...if it's not better, repeate the steps above.

Sometime i need "only" 15 mins to make the chips all green...
One time it took my almost 1h...but it works.

My config is with 900MHz, mining on NH and the new Firmware.

Good luck and have fun.

EDIT: Sometimes some chips need more time to turn from black to green.
So if most chips on a card are green and just a few black, i just wait 2-3mins and then they turn green.
