Bitmain launches the Z9 Equihash miner

[not.you]

Anyone else had an issue where the Z9 mini fan starts cycling high like it is restarting and the red fault indicator is solid red?  Just had multiple Z9's go into this state at the same time.  I thought maybe is was something to do with the pool, but I tried changing the pool on one of them to see if that corrected it, but it goes back to the same state.  I am running stock clock speeds, so no overclocking or anything like that going on.  Tried power cycling them and that didn't correct it.  Any thoughts?

My first thought is that if multiple ones did it at the same time it's network related.  I think considering the pool is also a good suspect but it sounds like you have eliminated that.  Swap a switch or something.

EDIT: One thing that just occurred to me, verify that whatever they are using for DNS can resolve the pool(s) you have configured.  Maybe they can't find the pool.

Agree, network related

So I have mined 1 ZEC at almost exactly a week of mining.  Based on prices I can say that 11 ZEC would definitely put me over 100% ROI so 10 more weeks.  I know it won't actually be 10 weeks, it'll certainly be longer, but that looks pretty good right now.  Reminds me of the old days of the early antminers when you could actually make a profit in the long run and ROI was under 6 months.

It appears it is something screwy with the Z9 on the network.  Nothing else was having an issue.  No more than sent an email to Bitmain and suddenly they came back online.  No explanation for this one.  Then about 15 mins later it dropped again.  I restarted the miners and they came back online.  Very strange stuff.  Rebooted the router for good measure.

I'm curious.. if ROI is on average around 6 months wouldn't it be better to simply buy the coin at today's prices and ride it up? Or is the point of mining to make money even as the price continues to drop?

Well, if you think the price is going to continue to drop then buying at today's prices would not be a good idea and you would lose money.

Mining on the other hand.... You spend $2000 on a miner, after 5-6 months you break even... after that everything is profit, get it? Risk vs reward. Even in the price goes down you can hodl the coins you mine, trade for another coin like bitcoin and hodl, or you can cash out immediately.

10 weeks? in three weeks the z9 will make $5 a day
theres tons of batches coming in a week or so, not even factoring in the innosilicon 50sol box
 maybe u break even in six months if prices rises

lol 5$ a day in three weeks. can i get some of those shrooms ?

it went from 30 to 15 in a two weeks.. and the inno batches are not even dropping yet
you have heard of this thing called difficulty right? if not two weeks 4 weeks who cares
these things will be in D3 territory soon unless crypto prices rise

making 35$ a day on btg atm

Currently i mine with 5 Z9.
BTG has procceed to a hardfork, we can't mine more BTG right? (Sry for my english)

[reapz]

I mine zec with mine, I just used the wtm calc to give the poster the roi wtm says btg gold no1 but if they forked already that makes sense

yes you still can until block 536200 maybe another few hours

Does anyone knows approximately how many Z9 mini antminers Bitmain will produce for second batch? Second batch should be a lot bigger then first?

[2Miners]

You could now mine with Antminer Z9 mini Equihash miner at 2Miners!

August batch is sold out now on Bitmain's website.

lol, the two weeks i have been running my army the results have not changed. it's been 2,6 ZEC /day every day (+-3%).

Hi all, since there was some speculation about the actual temperature maximums for the Z9 mini, I contacted Bitmain and received the following information:

Ambient temperature: 15-35C
PCB Max Temp: 80C
Chip Max Temp: 125C

I was told the PCB and Chip temps are the thermal cutoffs where the unit will shut itself down. Also interesting that their specs on the Z9 mini info page state an operating environment temperature maximum of 40C, but they told me 35C when I contacted.

This is all FWIW, but figured it might be helpful. Also explains why in my environment, when I have the fan set to auto, my Z9 regulates itself to mid 70s C, despite having lower temps possible with a higher fan rpm. Seems 70-80C is perfectly safe for the unit.

someone saying that there is a Z9, but that it is only 3X faster than the mini.

I'd imagine it is twice the hash chips, same board design mirrored, and run at 50% higher clock.
