Bitmain launches the Z9 Equihash miner

[dwood443]

Just wanted to add comment on Batch 2 Z9 minis.

My batch 2 Z9 minis (arrived today) have the drop down box to choose frequency. It has all the same frequencies as my batch 1 Z9 mini.

The only issue is that they are not steady when overclocking to 700 frequency like batch 1. The highest they will go without pooping out is 668 frequency.

Mine is running fine at 675. I also tried 700 and it ran for a few minutes and then one single board would stop completely. My temp at 61C and getting 14.9 average

All mine has under frequency is balance.  Do I have to downgrade the firmware?

Still no one alerted of z9 full miner shipments??

Still nothing here - 7/26 order date.

As linked just above  - quick way is to edit the using f12 via browser under your advanced settings to set the 500 value for frequency to your over clock (see https://bitcointalk.org/index.php?topic=3509006.msg45020727#msg4502072)  However another quick way depending on how your farm may be setup is just to ssh in and edit the file in /config/cgminer.conf and edit the frequency by hand there in that file, and then reboot the antminer (type 'reboot' if you are in ssh).

For those not familiar with SSH, check out a program calledWinSCP or  PuttY.  WinSCP is even easier, it lets you navigate and edit files too), and just connect using the default user 'root' default password is 'admin' to your port for SSH/SCP (port 22).  You can then if using PuttY edit the file using VI (good luck if you are new to unix, sorry but google is your friend).  WinSCP is much easier to remotely access and edit files on the antminer.  Perhaps easier than using developer mode (f12) in your browser to hand edit frequency.

Again the file is located in folder    /config    and is named cgminer.conf  - you may find it easier to manage things there on all your different antminers anyway than browser access if you have lots to manage.

p.s. I use 675 Frequency and get about 14 K up to as high as 15.92 K output - varies between my different Z9 minis for the same setting (all batch 2's) and even unstable on others.  Still adjusting to fine the best stable one.

edit: 3 of my units from 'china' (fedex delivery) clock at 675 fine and stable, produce 14 to 15.9 K output.  My other 3 units that came from Hong Kong shipping origin (DHL) all dropped out a chip after about 10-15 minutes, at 675 Clock Frequency.  at 650 Clock its stable for those 3 units producing about 13.9 K up to about 14.4 K.  Arrived within a day of each other this week batch #2 - the theory that different batches, and chip quality can differ would hold true.   Why hong kong vs china origin ship units differ I dont know.  Serial numbers on the 3 from honk kong end in 914, 919, and 932.  The China serial numbers are wildly different for letters and numbers, again all 3 arrived and shipped together from china.  Temps on all are 68C to 70C for what its worth on the over clock.  (Its hot out here and using open-air system with fans).

Does anyone have the timestamp of the cgminer.conf file and the /config directory from stock on September batch?   

I have a unit which is reporting oxoo on one of the boards, and need to restore back to original configuration before shipping it in.

Thanks!

Cgminer.conf will auto change time stamp any time you so much as change the pool information. It is over written each time.  So they can’t see you over clocked from that file if you simply set the frequency back to 500

The log files though show your frequency each reboot and startup so delete your logs or do a factory reset from browser first and then verify logs gone on file systems

My recent arrivals also came showing balance so I used ssh to get in, found the changed file, compared it to my older units and changed the html to match.  I used built in vi as the editor. Worked like a charm.

The file is "minerAdvanced.cgi" and the changes happen after line #225. Here is what I did.  If you know Linux and can follow vi.....

  vi /www/pages/cgi-bin/minerAdvanced.cgi

  :226,252d

then I copied and pasted the code for the frequency drop down (show below) to the end of the file just before EOT and saved the file when done  with  esc :x    ....

If you reboot, you loose your change...

[wsopft]

2 days ago i got 2 z9 minis delivered by DHL  and today i got surprise bill from DHL to pay £289 VAT im in UK

[roc-noc]

If you reboot, you loose your change...

Not when you save the changes to  /www/pages/cgi-bin/minerAdvanced.cgi on the Z9 mini.

+1... however i'm too lazy so i just do the F12 trick. set it and forget it.

I believe what Django69 meant was that the changes are lost when the z9 mini is powered off, not reboot.  The OS is running on non-persistent storage and any changes to the file system are lost when powered off.  The config (ie. /config) on the other hand is kept on persistent storage and any changes here are retained.  

When powered off, you lose your customized web page but your OC setting will still be set to what it was before the miner lost its power.

Good discussion guys. Thank you!

[hashestohashes]

My z9 came with the option to change OC's it doesn't say "balance", still doesn't go to 750 without crashing though.

Mini or full version?

[fccs]

No one has full yet, we are all waiting for shipments.

[minefarmbuy]

looks like spec had changed for the full, unless I'm late to the update from being on holiday. but 42k sols at 970w. Hopefully with OC's on cheap power.
