My shipment of Z11 just arrived. Installed the first one 5 minutes ago.

Mining on flypool.

Watch your frequencies -- it auto-adjusts. Will be interesting to see how/where it stabilizes. It is not clear to me if it continually adjusts frequencies or if it settles. -j All 4 have been running for about 3.5 hours and averaging about 140 KSol/S each. So far, 2 of them have dropped the freq on one chain to 724.

Thanks! 7 or 8 on my Fender amp They are pulling 7.1 amps each at 208 volts. That is 1477 watts. Think about 4 z9 minis running. To get rid of all that heat, you need a lot of fan and there are only 2 of them on each z11.

zcash mining difficulty spiked today at an all time high. But now is back down low. Looks like a lot of Z11s were delivered or else somebody in China is testing a lot of them before shipment. I also got hit with a $2127.01 charge from Fedex for the Trump tax on 4 units.

If someone has A) teamviewer and/or B) (preferred) knowledge enough to create an SSH/web port forward AND C) knowledge enough to do a SD card based install on a Z11, I've got an image to start testing with and see what these things can do.
PM me A and C or B and C with a Z11 are true.
Thank you,
Jason

Is anyone getting more than 142KSol out of their Z11? If so, how much?
I have a theory that I need to prove as true/false that the auto-tuning functionality might be auto-limiting to prevent it from going above 142kSol and will auto-adjust frequency down to ensure that is the case.

All 4 averaging 140KSol. One is showing 156KSol /RT but it already has one chain downclocked. Has been since yesterday. My two units with a downclocked chain have not changed clocking.

If the downclocked chain still hasn't changed, can you confirm again please? I have been able to test on a machine this evening. I can fully control these boards on these and I know that higher hash rates can be had by manually setting the clock vs. auto-tuning. That said, there appears to be a hash rate ceiling independent of frequency that I'm trying to figure out. -j

https://releases.broked.net/Z11StockSSHNoSignature.zipThis is the stock Z11 firmware dated Tue Mar 12 19:47:06 CST 2019 + SSH has been enabled + Signature checking has been removed for future firmware updates + Protection against the known antminer malware has been added + No Dev-Fee/Call-Home + No additional features or changes exist. This can be used to enable AwesomeMiner to manage your Z11 ASIC. SHAH256: 4c034f823a68d4a05254630a8082bad13136b3ae85399a3cfae2aac00227fb70 Z11StockSSHNoSignature.zip MD5SUM : 393430f23dd7ac3db0740ef7acabcc6f Z11StockSSHNoSignature.zip That will need to be installed via SD card: 1) Format SD card 32GB or less as FAT32 2) Extract zip file contents to root of SD card 3) Power off miner. 4) Insert SD card, power on miner. 5) WAIT (30-60 seconds) for lights to go off to the right of the ethernet port. 6) Unplug miner, remove SD card. 7) Plug miner back in. Enjoy.

all chains with same frequency after start - no change at all. Have to restart many times cause massive rejected shares (you can see "HW" errors are to much for my opinnion)
anyone has this problem too?
some seconds after reboot

I think hardware errors are normal on this platform now; I've seen them on every system I've looked at so far.
Are you seeing "rejected" shares or "discarded" shares?
If you are mining against nicehash, you will see rejected shares.

i have trouble with lot of rejected shares through miningrigrentals https://www.miningrigrentals.com/rigs/126089like you can see...rejected shares and hashrate went to zero - have to reboot the miner and after this...maybe 10-20 rejected / hour is normal and i dont worry about...but sometimes...90k rejected shares and only 30-40k accepted - could be pool related ?!

I would guess pool problem-- are you able to see what pools are being used during those rejects? .. I don't know how miningrigrentals works -- i don't know if they act as a pool front or if the user provides pool information.

i can set the pool...it´s only passthrough if no one rent this rig and u use 2miners and also tried miningpoolhub but why so many HW errors...my z9 mini´s dont have any HW shown after days could it be, that the chain auto speed is to high

I will say that the higher you push a board, the more likely errors will occur. The key though is the hash rate (and ultimately share submission rate). The DR5 and others throw lots of HW errors, but still hash/submit just fine. I personally use flypool and antpool (sigh) without issues on my Z units. Try it on another pool and see if you don't get the rejects... I will eventually release a firmware that will let you control the frequencies yourself, but until then that is the only suggest I personally have. At this point in time, I think ignoring HW errors is ok -- when they occur, there are no errors in the system log that I've seen that would indicate an actual problem with the hashes, at least the ones I have looked at so far. -j

I've been getting some rejected shares not too many, but enough to bother me. I tried nanopool and flypool both gives similar results. Then I turned my fans up as chip temps were running kinda hot 70C changed to fixed 80% fan. they r at 62C and it helped with hw errors. The 2nd 3rd chains that give me hw errors are staying at higher freq then 1st so chip temp was higher on them 2 chains. the increased fan helped with that so guys kick up the fans if temps r higher then 67C if def lowered hw errors for me . Thank you much efudd for your work so far kudos on quick fw with signature removal nice job 👍. I personally can't wait to be able to set my own freq to run more stable and voltage adjust wud be a BIG plus for sure. Bitmain shouldn't do this crap we buy these not rent so shud be able to configure as I see fit,same crap as cell phones finally letting people unlock their phones cuz if paid for them and own them. Big thanks and anyone here including me let's help efudd if needed, so we can control out miners ourselves not Bitmain picking our settings .

Thank you for the feedback.
I worked on an updated Z9 image today and hope to get a z11 image which gives you control back (but no real overclocking yet... I can make the boards go a lot faster, but hash rate doesn’t change, just how quickly they get up to speed)..
I am thinking it will be dev-fee free for at least a couple of weeks and then be like 20-25 minutes a day. Hopefully I’ll be able to crack the last bit and actually get more hash out of these soon... I am only able to work remote on other people’s systems so far.

Also getting a lot of rejected shares across multiple pools the last few days with the Z11. About 20% are rejected.
Can you link me some stats to look at in chat? I am pretty sure you are on the discord...

My Z11 is mining at MinningPoolHub, Zcash and getting an accepted ratio of 99.72%. I tried NiceHash and it was around 90%. My average rate is 140.43 kH/s. I have not tried other coins yet but all seems to be running well. https://i.postimg.cc/Y9LSMqjf/Z11mph.jpg

Specifically, what Awesome Miner and the Z11's control panel show with regards to hash rate is far higher than Antpool advises. So doing a test: 5 on Antpool and 5 on ZHash Only 5 hours in but hash rate is far better on ZHash. Will update test over next few days.
