Z9 performance and general discussion


#445

You’re rigth. Thanks for help! I’m writing pm now :slight_smile:


#447

Use https://guarda.co/ they never disappoint and have an overall great service. You also have total control over your Private Keys. All of our mining rigs are pointing to Guarda and we have 0 issues so far.


#448

ZEC Sapling supported? :slight_smile:


#449

Yes sir. Guarda loves Sapling.


#450

I use XMINER 1.1 to monitor the workers, can anyone tried to connect to Z9 thru SSH, I can’t get in, admin/admin, root/admin or any combination doesn’t work, can anyone help,


#451

Confirmed. Are all batch 3 units, tested today in the morning, Chinese morning. OC works fine and the low price is the outcome of the Z9 rebate.

It is also confirmed it makes no point to move them more than some hundreds Kms (or cross a border) and plug them where energy is pricey.

Jason,

what’s the time frame you set mining fee to run, how long or how often, we want to calculate the profitability risk/gain. We sent a small donation to your original address for 1.0 then modified your code a little, everything runs perfect under 650, I want to try anything above but not willing to pay something that I’ll not make it back. let me know.

10 minutes every 280 minutes.

Exception is on first start: runs for you for 10, me for 10. That’s just a preventative measure since someone would simply restart every 279 minutes otherwise. … and starting with mining for me didn’t feel right. I’m homing in on the fan controls (folk have requested custom fan curves, disabling fan on bootup/reboot, etc.) since they are not in the normal places. Voltage evaluations after that… If you have machines with slower hashboards, they don’t have to drag the rest of your system down… so returns above and beyond the 20-50% already provided will be a function of your environment… but supporting the firmware does support future features.

… plus I do respond pretty darned quickly to questions. :slight_smile:

Thank you,

Jason

so roughly about 50min a day for a rig, ok, I’ll pass that up and will PM you in few minutes.


#455

Yeah, it’s a little less than that on the long average because it doesn’t break even into a 24 hr period. It is roughly 3% of the time plus/- a tenth of a percent. I tried to make it as unobtrusive as possible. The 10 minute window is a function of how long it takes for miners to ramp up the difficulty on share submission since many pools do not support specifying difficulty up front.

I probably will need to tune it again in the next major release because 3% is the target and I think it may be overshooting that by about 4-6 minutes.

Thank you,

Jason

Hi Jason,

you did a very good job. The problem I see is the numbers of pool’s change. As you said, 10 minutes is the time for the miner to ramp up, so we could, roughly, say the machine loose 15 minutes every 11/12 hours. This may work as personal solution, I could understand it and accept it, but cannot resell it. But, I would prefer to give you 10 hours every 1st of the month, consecutive. It would be better for you and for me.


#457

Hey bruno - drop me a PM if you’d like. I am not sure about per-month, but the per-day could be batched into one batch a day and then amortized across miners as a potential option.

Thank you,

Jason


#458

Now this is interesting… The Z9 Mini is now NO longer listed on bitmain for sale!

#459

Yeah, the Z9s went live a couple of days ago again with the Minis going MIA.

#460

Mini still available in SZ. Price very affordable…


#461

Folk,

Just a follow-up; If you happen to represent a farm, I can provide complete configuration automation of your antminers (not just Z series units). Plug them in, add firmware, that’s it. If this is something that meets your needs, please PM me.

Thank you,

Jason
