A humble Siberian miner

Why not make a web-interface to configure and monitor the miner?..

How to change ip

1. To change ip, subnet mask you have to modify file that located at:

Code:

/etc/network/interfaces

You may also choose from "dhcp" or "static"

2. To change the pool and worker settings you have to modify file that located at:

Code:

/root/.cgminer/cgminer.conf

NOTE: .cgminer is hidden folder.
you also have to have ext4 extension. You may use Paragon software or kind of that

3. Finally you have to modify gateway. The file that located at:

Code:

/etc/resov.conf

How to change ip

I'm not sure what version of the software you have. I've got a super early one, you may have the new retail one.

Nice guide Dogie. Appreciate the work you put into it.

What will happen to the miner you received for review? Are you sending it back or did you get to keep it?

There's no point shipping 30kg miners round the world twice, and I need the unit to be able to help others.

Thanks a lot for this review! It's well done, as always and gives us a good overview over the new XBTec miner! Do you have any guess how many miners they're able to churn out every week? Can anyone make an educated guess?

I don't think anyone ever can. There isn't really bottlenecks to manufacture any more, chips are in hand, PCBs are easy, assembly is easy...

Obviously I wouldn´t suggest anyone builds a datacenter without ventilation.

It was merely meant as an example that the miners should be fine on max fan settings, if there are (temporary) cooling problems at the hosting site.

Well, it is good to see a unit which is properly optimised for free air cooling, even in the toughest environments.

They have a very solid cooling design, I find that most professionally built units from China are built with demanding climates in mind, as their hot and humid summers put a lot of pressure on miners.

Basically, the unit should still run fine on max fans even if your datacenter ventilation completely fails, which is a nice feature.
Dynamic fan adjustment would obviously have been better, but this option should also do the trick nicely.

We have a huge fans in our farm to prevent overheating.

Its worth noting that the high fan mode was just added for people wanting to OC

Well, how can it be overclocked? Does the error rate remains the same at any of that three pools or may vary from pool to pool?

Its got BFGminer on a known controller on a known chip, it won't be long before people give it a go. I test everything on BTCGuild, rarely GHIO if there is a problem. Pool variance isn't relevant in a hardware scenario.

Ah okay, so you are basically stress-testing the unit.
The quoted 45°C temperature might presume that you would use the 5000rpm fan mode though Wink

Are you planning on testing the overclockability tomorrow?

They've said they don't use it even in their 40C farm, and performance is absolutely fine.

Thank you, does that put the total error rate at 5.9% aka ~1176GH at the pool?

It would be very nice if we could get an update after 24h, to have a good average.

37°C also seems rather brutal (at 2500 fans that is), do you have access to hosting at a cooler facility?

No its post reject, so I'm getting 1.26 at the pool after 6 hours. I've lowered the difficulty to 512 which effectively doubles the run time of the test by reducing luck variance. The hardware isn't shifting at all.

I'm forcing the test cell hot because they quote operating range up to 45C, so its only fair to see what happens at that range. At 25C it was overperforming at 1.30. Its worth noting that the high fan mode was just added for people wanting to OC or who live in the centre of the sun etc, you don't actually need it. Its one of the significant advantages of the BE200 people didn't really notice.

Nice review and pics, Dogie.

Have you done any mid/long-term testing to find out the average hardware error rate / poolside performance?

Are you going to provide screenshots from the hashing unit or is the GUI still so ugly you would rather not have anyone see it?

I never take screenshots of software because they go out of date so quickly, and people tend to refer to them over the instructions and then get stuck. Error rate @ 37C ambient and normal fans is averaging 5.4% after 5 hours, 0.75% HW. Stats are taken directly from the BFGminer inbuilt so pool side is identical or above.

Anxious to see some screen shots of performance Dogie. Solid instructions as always. I like your consistency in an erratic industry.

I did not mean to make that rhyme.
