These boards work great right out of the box, I dont know why you would warn against them.

you should, as a general rule, stay away from MSI motherboards. Based on extensive testing, these are the hardest boards to get working properly.

Set the subnet to 255.255.0.0 and you will be able to access anything on 192.168.xxx.xxx

Nobody can answer that question as you did not provide enough information. What algo? What miner? What mods have been done? etc

Remember the error codes are additive. For example if you have an error 32 and an error 8 it will show as error 40.

The easiest way to check codes is through their query tool. It will list all applicable codes.

If you have a newer batch, the older firmware will not work. Overclocking is a very bad idea anyway. By your post focusing on temperatures I dont think you quite understand what an overclock will do to the gear. Temps have little to do with anything when you are trying to put more power through a set of components that it was designed to handle.

Please setup a 24/7 camera that is recording so we can see the moment where the machine blows up and starts shooting fireballs out the back.

Overclocking bitmain gear is extremely stupid and I hope this doesnt give anyone else ideas.

If you run quality server PSUs there really is no issue as they have protection circuitry built in. Its using the shitty bitmain PSU or an ATX psu where you will find problems.

Neither of those are stats that the Avalons track. If there is a failed chip on the Avalon board it will show up as an error code. HW errors can pretty much be safely ignored as well as there is nothing you can do about them.

Beeping almost always indicates a loss of network connectivity. I would say change our your network cable. You also might have an intermittent fan failure, that would be something else to look at.

Those temps are not on the high side at all. The temps you list are similar to my machines that are currently sitting in a 60f environment. These machines wont even throttle until they are over 105c so sitting around 90 is just fine.

I am speaking from the position of a company that is trying to be successful. If a business thinks like you it will fail rather quickly. The point of bringing a product to market is to sell as many as possible. This whole idea that companies should be altruistic and worry more about the ideals of individuals than making a profit is incredibly naive.

This will never happen so that theory can be put to bed.

They have already said they will not be selling their 12nm chip. Who knows if it even works.

That board looks like a major step back in design, it reminds me of those terrible cointerra systems.

Mining in windows in general is asking for trouble. Almost as much as buying random weirdo untested chinese motherboards when there are a ton of compatible boards out thre in the wild already. Is there any reason you guys are going for this janky looking junk instead of buying a known working board?

if you say its because of cost, count the downtime you are having trying to get that junk working and see if you really saved much 

Mining on anything less than a higher end 9 series card is a waste of time. Those will use so much power you wont make any money, this is a 6 year old video card after all.

You need to look at more than raw profitability, especially when you consider those numbers will be wrong by the time the card is in your hands.

Vegas are a nightmare, I personally would never buy one and warn all of my friends away from them. You should look for a 1070 Ti over the 1080. This gives you maximum flexibility going forward.

When looking for new buildings, I always look for the maximum amount of existing infrastructure I can leverage. Old industrial sites and places that had/have heavy machinery are the sites I would focus on. Due to the electrical demand, sites like this almost always have a substation right next to them, then its all about power delivery. Buying directly from the provider is usually a bad idea, for the kind of power you are looking for you should contact an energy trader local to the area to see what options you have when it comes to buying the power.

An alternate way to get around the location issue would be to power the miners up 1 by 1 so they grab sequential DHCP IPs before staticing. Theres always multiple ways to do things and in the end most of them work. Good job on the script!

Because I didnt pay that much *shrugs*

This will happen in any industry where you can make the kind of insane money you can with bitcoin. Why spend all that R&D time on some stupid little stick miner when you can sell companies big miners by the thousand? Bitmain even tried to make something you could run at home, yet they continue to get blamed for centralization when it was bound to happen anyway, even with more manufacturers on the market.
