htautosjay - it will vary to be honest. With the per-hashboard feature, I've been able to get +5% out of batch2s. That isn't 16k on most, but is an additional 5% from baseline. Tuning takes some work though. Dev fees are disabled until 12/1, so you are welcome to try it on a mini and see.

To tune:

1) Set global frequency to 650. Set each other frequency to "Use Global".
2) Observe your boards for at least 10 minutes, if any drop out, on the next cycle decrease their frequency by 1 step in the pulldown.
3) Repeat this cycle until you have a stable minimum frequency for your boards.
4) To start the 'upwards tuning', choose one board (#1 for example) and increase it's frequency by 1 step.
5) Observe the board for at least 10 minutes to see if it is stable. If it is, repeat #4. If it is not, drop down 1 step and move to the next board.

Going through this process (which hopefully makes sense), you should be able to tune your units for your individual system maximums. It's best to do this with the fans set to 100% so you can remove thermals from the equation -- after which, set the fans back however you want them and see if your boards stay stable. If they do, good, of they don't, eithee decrease freqeuncy by 1 step or increase fan.

Good luck!

Mini support is now available in the Z Series firmware. Please see my other thread for details.

Thanks!

here you go.

i have test 2h today with a lot of rejected...

I switched my Z9 minis (6) about 2 weeks ago, and happy with BTC :-)

For more information like mining single coin you read "help" on prohashing.com site.
(Port 3336 is for Equihash algorithm)


Miner number 1
Pool 1:

and so on ...

I use prohashing.com with multiswitch for equihash algorithm and autoexchange to BTC + LTC.

nanopool.org as backup pool mining ZEC(Zcash).

and finally

MPH with multiswitch for equihash algorithm and autoexchange to BTC as last backup pool.

Subsection :  Make the Most Money Possible
"Prohashing not only merge mines coins, but distributes users among different coin networks with a custom algorithm that prevents mined coins from crashing in value or soaring in difficulty. Prohashing monitors every coin with every price change and every new block. The algorithm recalculates profitability multiple times per second, ensuring that the pool is always mining the most profitable coin using the most up to date information. Our debt to you is locked in the coin you choose at the time of earning, so you have no risk if the coins we mine with your hashrate decline in value."

i use luxor pool currently for zcash and sia. they have a promo 0% fee for zcash

Just checked. In fact, the autotune miners run the fans at slower speeds.

If the readings are right, can someone explain this:
On autotune FW @14TH I get 90°C. Same miner with 650FW and stock settings @14TH shows 110°C. Power consumption is the same. So why get the chips hotter?

UPDATE: I flashed my batch 3 with the batch 1 firmare and am able to overclock this Batch 3 unit to 750 freq. It's only been running 10 minutes so I can't speak to how stable it is; but my batch 2 units will crash almost instantly or 2/3 boards refuse to start hashing above 673 freq. My batch 2 run at 625 freq for about 13.75 ksol/s stable because I had some boards crash with some units even at 631-650.

I will edit this post if I experience any stability issues.

Batch 3 Z9 Mini
15 ksol/s stable @ 750 freq

PCB Temps: 64*c ish
Chip Temps: 70*c ish

Can somebody please tell me if I get this right:
The difference between the fixed frequenc firmwares is the voltage, right? So If I load the 650M firmware on a S9 with stock 14TH, it will assume it has good chips and give them LOWER voltage than the 600M firmware, right?

So could i just load the 650M firmware on my S9 and check what frequency it accepts?
Problem is that as soon as I load the fixed frequency firmware, the temps show above 100°C. But i think the readings are not right...

Any advice?

I see that I made a mistake under "Password" regarding "n="

You choose some name and / or number that makes it easy for you to identify like:
z9mini001
z9mini002

or whatever suits you!!!


Login to your z9 mini's number 1 - 3:
Goto Page "Miner Configuration - General Settings"

and so on ...


Best of luck!!!

If you point to
Url : stratum+tcp://prohashing.com:3336
it WILL be autoswitch.
You will need to have something like this
password : c=zcash n=your_login_name_at_prohashing.com
if you wan't to get 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":

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 !!!
