Antminer Z9 mini overclocked

[grinbuck]

I don't think so. I currently have 5 z9 minis connected to 2 apw3++ psus on 110v without issue. However the above poster must be using a splitter to connect all 3 to 1 PSU which from what I understand is something you are NOT supposed to do.

Don't think it matters as long as the splitters are good quality and total draw is well within the rated limit. Time will tell though. Will report back if there are any issues.

Antminer-Z9-Mini-NAND-500M-201808311812.tar.gz

Is it a new firmware form Batch-3? Has anyone tried it? What is about overclocking?

forget it. it cannot be overclocked. neither the SSH / WEB F12 edit mode is working.. stays at 500MHz, so you need the MAY for that. or the AUG 12th..

Do you know with a 750 the miner is slower than 700 ?

when I set up Z9 mini at 700 I get 15.5 Kh/s while at 750 14.5 Kh/s !

This is not correct. You need to be looking at the average hashrate taken over a long period of time, I assume you are either looking at the current hashrate (it fluctuates quite a bit) or not giving enough time to calculate an accurate average.
my average at 750 is 16.95 Ksols/s over the past 24 hours. Sometimes into the 17s

Actually he is correct. Every batch 2 i have played with either has a reduced hashrate or none at all when running at 750. Personally I cant push mine past 675 without dropping boards.

Another thought I had is that the hashboards could be self throttling if the temps are too high at 750. Otherwise I could be wrong, i'll experiment with 700 for a day or so & then report back if I remember.

Are you talking about batch 2 or batch 3, because my batch 3 is working stable on 725 for more than 24hour hashing avg. 15.8 kh/s

[Gangzsta]

Ezeiza,
Did you flash May's firmware on your batch 3's?

Yes

[MinerLamp]

Ezeiza,
Did you flash May's firmware on your batch 3's?

Yes

Can somebody explain to a total noob how to do this? I just got my batch 3 and no option for overclocking, how do I flash older firmware?

never mind, found the may firmware upstairs, works fine so far

About firmware versions and overclocking:


I've been doing some serious digging!!!


When you login to your Z9 mini you check on first page "System - Overview"
Batch 1, 2 and 3 all seem to have
"Hardware Version:" = 9.0.0.5

"File System Version:" tells you which firmware version your Z9 mini is running on.

There are at LEAST four (4) different firmware versions for z9 mini:

1. Sat May 26 20:42:30 CST 2018 = Antminer-Z9-Mini-201805262047-500M.tar.gz
2. Sun Aug 12 17:43:41 CST 2018 = ? ? ?
3. Thu Aug 30 14:57:48 CST 2018 = ? ? ?
4. Fri Aug 31 17:02:59 CST 2018 = Antminer-Z9-Mini-NAND-500M-201808311812.tar.gz (the now only downloadable fw on Bitmains site for z9 mini.)


May 26 and Aug 12 firmware-versions are overclockable either from SSH into machine and changing the file "/config/cgminer.conf" or from Chrome using "Inspection" for the field where you choose "frequence" (May 26 version) alt. "mode" (Aug 12 version) on page "Miner configuration - Advanced settings" and for the May 26 version ofcourse you just choose the frequence here you wan't just like God intended !


Aug 30 and Aug 31 versions just ignores any frequence value from cgminer.conf or with Chrome's "Inspection" method.
If you go to the "/www/pages/cgi-bin/minerAdvanced.cgi"-file and changes value and saving (after you already made the filesystem writable). After reboot it will have changed the file back!!!


Batch 1 seem to be very overclockable !!!
I, myself, are running my single batch 1 Z9 mini on 768 MHz and it's solid !!!


For Batch 2/3 I have seen quite a few running them on 668 MHz solid with both fw May 26(after upgrade) and Aug 12 firmware's !!!


WHEN you install(upgrade) the May 26 firmware using the page "System - Upgrade" I strongly recommend you UNcheck "Keep settings:" to get as clean install and as little problems as possible.


I really recommend you checkout mining at prohashing.com dispite their "high fee" (not high in relation to what I earn compared to MPH, nanopool and flypool after 48 hours, at least for me and my friends.) Read under "Help" on prohashing.com for further info and earning possibilities if you choose a single coin to hash.)

Do you earn more on Prohashing then Mining Pool Hub?... I have been wondering where the best place is to point my Z9's ..
Will Prohashing mine on Autoswitch?. BTCP, HUSH , XEC, ZCL, Ect and payout in BTC?
Thanks

If you point to
Url : stratum+tcp://prohashing.com:3336
it WILL be autoswitch.

If you only want to mine a single coin you will need to have something like this:
password : c=zcash n=You_choose_some_name_and_or_number_that_makes_it_easy_for_you_to_identify
This is if you wan't to hash only one coin and in this example it was Zcash.

Letting all your machines mine one and same single coin (not solo mining) WITHOUT converting will give lower fee AND share rewards you don't get in my case.

I convert to BTC and LTC.
Because I get immidiate conversion on prohashing and can choose have many % of each like 80% BTC and 20% LTC conversion I wan't I do not risk loosing as much because of the loong unknown time it takes for MPH to do the autoexchange since BTC can move alot in that time.


Furthermore on MPH the multialgo on port 17023 is not in sync whith Whattomine.com and also seems to move big hashing-power between the different algorithm's in a way that I beleive influense the other algorithms negatively.


As I understand it, on prohashing.com I can be rewarded for parts of work my machine done (read "Help" on their site) even when "too late" and I seem to get better "2hr avarage solrate" hashingspeed for my z9mini and for other friends they have been getting ridiculus speeds on their Innosilicon A9 ZMaster's when loggin in to them as well as on prohashing "2hr avarage solrate" hashingspeed both in "balance" and "performance"-mode with different firmwares AND the problem they had with there A9's whatever firmware with restarting because memory full seems to be gone. Their logs dont't get clogged up with as much as with MPH, nanopool and flypool and others. Before they had to restore to factory defaults between 1-2 weeks apart just to keep them spinning for more than something like 8 hours before their A9's would restart. After facory restore they could get 1-1.5 days and for every restart it would get worse.


Seems like prohashing.com calculates each and every machines hashingpower and timedelays and manage to choose which work/coin/difficulty to give to each machine with better earnings as a result.

My z9mini has also shown quite a few impressive 2hr delta hashing speed up towards 20ksol/s.
But hashing speed goes up and down.


I have also "found block":
Algorith     Coin        blockrewards   fee            difficulty         value       status
Equihash   Komodocoin   3   0.001356   1,443,172,861   $2.9901   Mature


I just say that give prohashing.com a day or soo if you feel that you are not satisfied with the miningpool(s) you are using now!


(And I live in Europe so I do NOT have anything to do in any way with prohashing other then being a little bit more satisfied and hopeful with my limited earnings.)

If someone else tries prohashing.com I hope they will give their oppinion whatever it is !!!

Is it dangerous to connect multiple ASICs from one PSU? 

it's the other way around. it is dangerous to connect multiple PSUs to a single ASIC.  you can connect as many asics you want to a PSU as long as both your PSU and the 6pin connected can handle the power needed. from a theoretical point of view you can have 4 z9 minis connected to 1 APW 1600w psu ( each z9 mini takes about 350w if not overclocked" ). how ever i would not do that until i verify that the 6 pin connectors which are going to be split can actually handle the load.

You choose some name and / or number that makes it easy for you to identify like:

You don't want to run your engine on max RPM to loong.

It's the same with PSU's.
