Hey Guys,

Re: Miner Info section of Miner Status of A9 ZMaster.

What does HW stand for? And, what do the numbers mean?

Thanks.

Hi guys

I'm having a few problems with my A9s and was wondering if anyone else has experienced the same. I browesed through most of this thread but didnt answers directly.

Temps are decent at 60-66 without modifying firmware. Place has pretty good ventilation.

Problem 1)
Every 1-2 weeks each miner crashes. Not as in reboots, but crashes so I have to manually go to my site and reboot them. Any experiences or fix for this?

Problem 2)
Im only getting 92-94% accepted rate. Poolside im at 142ish for 3 A9s.
Is this low accept rate normal?

Best,

1) Try to find a solution where you can toggle wall power on / off from internet.
I would try to find a solution which I could control from my iphone.
could be part of alarm system.
could be separate gsm/3g/4g mobile network control with it's own sim-card.
or whatever but as I understand you need to toogle power off and on from remote location.


2. try to get mining pool with lower latency if possible

good luck

I think it stands for HardWare error.
can be big difference between each hashboard.

From what I have seen, a rate of something like about 5-25% from "Accepted" seem's quite normal.

But I hope someone who knows this for sure will give you an answer!!!

would someone have the balls and open their A9 and remove a heatsink of one of the chips and make a detailed picture of it? i would pay money for that. please PM me

Why do you need that if I might to ask?

"documentational reasons"

Best,

Temps are really good.

Problem 1 - From my experience every A9 does that. For that reason the best way to solve it is to buy smart plugs so you can open/close the miner. A very detailed guide has been published from a user that even has a script to automatically restart the miners. I think he has TP-Link smart plugs.

Problem 2 - That depends on the pool that you are. The speeds are logical that you get. Try different pools to see if you can get lower errors and better hashing speed.

there is some thread here with chip photos from the bitmain Z9, maybe you mix up these two miners?

Thank you all for the helpful input.

I already have two HS110 laying around. Guess ill make a dyi adapter from PDU -> HS110 so i still have the safety of the PDU.

This guide, would you happen to have a link to it?

Hello Guys,

I have up-to-date firmware for the A9.

There are 4 performance options available:

1. Efficiency
2. Balanced
3. Factory
4. Performance

When I click on Balance (to change from Factory), I then click Save.

I then reboot.

However, when I reboot and then check the options, Factory remains as the current mode.

Where am I going wrong?

And, what are the actual differences in performance of all 4 options?

Thanks.

Please check the previous pages of this topic, it is there.

Did anyone try the October firmware? Any interesting info about it? Will try it on one miner later.

Hallo guys, how can i change the fan speed of the A9?

[imine2]

Hallo guys, how can i change the fan speed of the A9?

For SSH you have Putty.exe.
https://www.chiark.greenend.org.uk/~sgtatham/putty/

SSH in to A9:
user: root
password: blacksheepwall



cd /config
Press "Enter"-button
vim cgminer.conf  ('vim' = editor)  (You should google keyboard commands for vim-editor)
Press "Enter"-button
i    ('i' = insert mode) (NOW u can change in that file) (BE CAREFUL)
(Use arrow keys to navigate)


When you check the file it should be something like this:
{
    "pools": [
        {
            "url": "stratum+tcp://50.225.198.65:3336",
            "user": "imine2",
            "pass": "n=a9zmaster111"
        },
        {
            "url": "stratum+tcp://eu1-zcash.flypool.org:3333",
            "user": "t1d35jvkzKcWybpCqojZmgDZkcFC7iBwe8w.111",
            "pass": ""
        },
        {
            "url": "stratum+tcp://45.79.223.173:17023",
            "user": "imine2.a9zmaster111",
            "pass": "x"
        }
    ],
    "api-listen": true,
    "api-port": "4028",
    "api-allow": "R:0/0,W:127.0.0.1",
    "A1Fanspd": "30",
    "A1Fanmode": "0",
    "T1adjust": "3",
    "T1performance": true
}


YOU want to add
A1Fanspd and A1Fanmode like you see above


(when done do this)
Press "Esc"-button    (ONLY ONCE)
:wq!
Press "Enter"-button
(You will get warning that read only or something.)
Press "Enter"-button again anyway


(verify that your change has taken effect)
cat cgminer.conf
Press "Enter"-button


And for changes to take effect:
systemctl restart cgminer  (restart A9 from within SSH session)
Press "Enter"-button

super, i will try thank you!

This ASIC has an energy efficiency 2.5 times greater than Antminer Z9. It gives 50 Ksol/s, which is 12.4 W/Ksol, Antminer Z9 - 40.8 Ksol/s at 28.18 W/Ksol. An excellent choice if the price of cryptocurrency will remain at least one year at the current level.

has this miner been overclocked yet? what are the results?

No OC so far ... ( or no one say it ! )

Choosing :
Performance+

(in Settings - Performance)

Thats it AFAIK !
