is there any chance to add to monitoring software the ICMP/ping function?
when remote restarting (in my case relay switches) the rig instead of RDPing in it or using VPN to monitor the rig is responding or not one just can simply use remote from HTTP and see if the rig appeared online or not after restarting, I hope this is not only my concern

just wait for couple more days and see what happens
All of us want's to get batch 1 but in most cases they aren't worth it
just wait a bit more

A fool and his money is easily BITMAINED 🤦🏿‍♂️😂😂

Lol BITMAINED. /cheers

That should probably be a coined term by now. Anyway this seems like a trash post. The OP said "19-20" A3 miners? What you don't know how many ASICs you own? Don't understand what the intentions of the OP are but this is trash. Obviously SIA and CN ASICs will die soon.
may be he was turning off and on 20th A3 who knows, that's why he said 19-20 and not rock solid 20
anyways it doesn't matter, the point is right, but I don't get after D3 and after all bitmain did how can you invest this much

you want us to pay for your mining operations?

we offer a vast majority of our tokens - 85% to the public, while the remaining 15% is split among team and advisors, company reserve and bounty campaign.
So yes you want us to pay for it
Like golden fleece did

here this might help

I saw it on Tallinn blockchain conference
I think they worked quite a lot with modifying the correct ways of airflow and stuff, there also will be some cooling options for higher temp environments
let's see were it will end

nobody minds to pay dev fee, but it has it's limits right?
5% isn't a dev fee any more, when you are on public and have so many people using your product

94  Alternate cryptocurrencies / Mining (Altcoins) / Re: Bitmain Antminer V9-4T Released for sales - MOQ - 5 on: February 08, 2018, 04:00:45 AM
Good for Bitcoin Cash!

Mainly you have to buy 5 unit as $350 each x5= 1750 + 5 psu 515 shipment UPS quick and safer 150 (ish) tot $2725 maybe + customs
mining return as today is approx $450/month + power

I mean if you mine to stuck up BCH and wait going to appreciate in future it's okay investment but still 1000W each unit mean 5000W ... not sure if you really like to get this deal for short term investment!

My guess right now Bitmain it's just guessing what to sell and for sure they got more freedom to build up because got kicked out the mainland to do production and maybe found a better place to build up their units!

It's just raising cash and give the illusion to chinese home they can resell units in alibaba for crazy profit as they been doing last year when where was shortage of units!

Another thing to keep in mind its starting to become more competition for Bitman not maybe not strong yet, but some people start to do the mat and selling 1000 units x $2000 = $2,000,000 it's good money and easy money especially from a country where have no problem to: build up hardware for few $,  cheap labor and $0.02/kwh in average!

What I am saying they are afraid to lose leadership and Obelisk it's a first call other way no sense to sell first batch of A3 for more then $2000 and all the sudden for $950 after Obelisk sold two batches of Sia Asic for $1500 for more than 3000 units (off course not ready yet but still) good waking up call!
quick mafs
They ain't gonna loose leadership and if they will in nearest future, they will still have tons of customers with them.
Not sure who and why someone will buy rebranded S7, but I know that people will, with free electricity and lots of cash it makes sense

That is so right. That doesn't need much explanation on it. It's part of beginning human but, holding is working out the best for me. Good luck everyone.
agree
but those who can't afford to hodl are the contributors
even me in some cases, I only hodl what I can afford, that's sad I know

my oldest AMDs are2.5-3 years old, with 0 issue, they had been through a lot.
480 series are 1.5 old or so, they also had seen some rough times, but out of 600 only 2 had issues that I couldn't fix, no one could

According to SiaMining Stat, the difficulty recently has dropped from 12m TH to 7m+ TH.  Anyone knew why it dropped so fast?  One possible reason I could think of is be many A3 started to break down?


diff is being corrected after hardfork on 139000 block... so it will go down till reaching 10m block time

Not really understand what diff is being corrected mean.  Will this help on those A3 owner any?

Yes - means we are all getting more coins per day. I am up about 50% today in amount of coins per day my A3 is mining.

The first batch will ROI before the 2nd batch ships, no worries there. Than the second batch should have a similar ROI based off the lower price point.
it will ROI I'm pretty sure of it
my 15m profit got from 9SC to 17SC almost doubled in one day
98  Alternate cryptocurrencies / Mining (Altcoins) / Re: Are there any resources that I can learn about mining on: February 02, 2018, 08:36:37 AM
the best thing you will have is passion and interest
all you have to do is to use google and this forum properly
we have access to the biggest knowledge base and it's right in front of us
don't hesitate to ask questions, but remember asking questions before your own research will result in zero response, while asking questions after your research on the subject will cause discussion around it, which will be way more ifnormative
99  Alternate cryptocurrencies / Mining (Altcoins) / Re: 30kW mining farm - need ventilation advice [Reward] on: February 01, 2018, 07:35:13 PM
@Sandal_hat, thank you very much for the very detailed answer.

SHELVES:
These mining rig cases will be used (Veddha 8GPU Mining rig case: https://i.ebayimg.com/images/g/QpcAAOSws1ZZs276/s-l300.jpg), they can be stacked, and no shelves are needed. The downside is that you have to take all off, if you need to remove and service the bottom one. Is there any other advantage for using shelves? Perhaps higher distance between each rig, and the shelf between, so air doesn't go up to the above rig?

FAN:
On the image above, the fan is misplaced, the idea was to have it centered in the room. I guess two fans would be good for backup, but it's probably much more expensive, since each will have it's controller etc, but of course, no fan running at all with no mining would be very costful too.

How much air volume is your fan moving, and what is the average temperature inside your mining room, and outside?

I got a recommendation from a ventilation guy using this formula:

V = 3P/T2-T1.
 
V = Air volume (m3/h)
P = Power consumption to exhaust (W)
T1= Outside temp (ºC)
T2= Max temperature in mining room  (ºC)

In an example during summer, where it can be 25ºC, and I want the room to be 30ºC or less:
3x30000/30-25 = 18000 m3/h.

With a pressure drop due to ducts 250Pa he recommended a fan with these specs:
Air flow: 31500 m3/h
Max pressure: 600 Pa
Weight: 94 kg
Sound: 74-77 dB (yeah I guess that's pretty loud?)
Consumption: 3kW
Fan diameter: 1020 mm
RPM: 1450

How does that sound? It sounds HUUGE to me.. Smiley Price for that is about 4500 USD if i try to convert it. Plus controller, sensors, accessorier.
The weird thing is that I find lots of fans on Alibaba for $200-300. How can it be so vmuch cheaper? I don't have to ship it, but it's still 4-5 weeks shipping.

I'd rather make it bigger than it needs to be, and be done with it, than change it in a year.

Great idea about the vents directed away from the machines.

Thanks again! Smiley

At first, I wanted alot of fan power (based on wat I read on the net and some calculations) but the engineer recommended me about 5000 cmh and I end up putting about 5500 CMH only. I can control the fan speed via a controller but I just leave it on near full power. I only lower the fan for a couple of seconds when I change air filter paper. If I buy an additional slide-in panel for the filter, I can probably change it by juz changing the whole panels and not the filter paper. I wouldnt need the fan speed controller then lol and can juz leave it at full power. I dont use any sensors, juz a simple fan speed controller, something like this http://img.directindustry.com/images_di/photo-mg/5369-9723484.jpg  . I skip using those expensive variable speed drives....dont need it lol.
 
My area is about 24-32 degrees and weirdly, I can get around 30 degrees inside when outside is 32 degrees but this is on the cold side of the miners. I never measured the hot side as the air is bound to be hot. More importantly, there is only 1 row of shelves and all the hot air goes into a sort of collection area and is immediately thrown out by the fan.


I wonder if 18,000 cmh is overkill. Bare in mind, 18,000cmh is huge, and so if any water gets pulled in the intake duct, it is going to pull the water quite alot in the direction of air flow. Also, the exhaust fan may push the air outside quite strongly for a few meters. Do note, u dont want trees receiving that warm exhaust air as they will probably die. U should check how far forward the air will be pushed out and if that will affect other stuff. Also, make sure the exhaust hot air cannot come back in if the wind changes direction.

Your antminers will be far louder than your fans. There are far cheaper fans on amazon also. I used an expensive box fan due to the need to fix it with ducting, a fan speed controller and I also rig it to off the distribution box if it were to malfunction. Also, it is only 1 fan and once fixed, I dont wanna move it.

I have 27 D3’s and 1 x S9in a tiny room in a warehouse.

I had huge issues with cooling to start.

I resolved this pretty easily.

400 mm intake fan into cold isle at low level

A 600 mm mobile fan in centre of cold isle facing upwards

600mm exhaust fan in centre of wall on hot isle.

The fans were from eBay around £250-£400 each.

I have control software which then lowers / raises frequency according to antminer temperature.

The 600mm fan is probably only slightly quieter than the 28 antminers that are running!

I’ll get a pic up if it will help
How many CMH of fans is the exhaust fan? By right, if u push air outside, air will automatically come in, u dont need an intake fan.
The centre fan helps cool the miners? What temps u have outside and wat are your antminer temps?
it is better to also use intake ones to reduce load on exhaust fans
