[CLOSED] 1THs 1kW 28nm Miner - $4200 - March 18th, BTC, Wire, Paypal - Last Call

[Cheeseater]

I've tried both. Same results 

Ugh! On to the next, have you taken it apart and checked for loose connections?

[DimensionsOfHell]

Ya, took apart both miner. Nothing is loose as far as I can tell. Pushed all cables in just to make sure.

[Cheshyr]

Just got off the phone with him; it's resolved.

There are 4 network settings fields that need to be completed: IP Address, Subnet Mask, Gateway, and DNS Server.  If any of these fields are missing or incorrect, the unit will not be able to access your pools.  I would recommend using ipconfig or ifconfig to look up your current home network settings.

You have two and neither will hash?

That's what was going on. Got off the phone with Dave, he figured out it was because of the DNS setting. For some reason mine were set up with 0.0.0.0 on one and 8.8.8.8 on the other. I changed them both to 0.0.0.0, and none of them were working.

[Cheshyr]

8.8.8.8 is actually a Google Public name server, which is why that unit worked.

8.8.8.8 use it on all my miners

[DimensionsOfHell]

I didn't know that would break it. One of the machines did come with 0.0.0.0 though and I figured I'd keep all the same settings to make things easier, boy was I wrong. Had 6+ hours of frustrations!

Thank you guys so much for all the help. I really do appreciate it!

Special thanks to you Dave, you've been great through all of this.

I will def do another GB with you, and I promise to give you less hassle next time



On a side note.... anyone know how to SSH into this unit? What port does it use? And whats the user/pass? root/root?
I just want to access CGMiner to view it.

I think you just putty the IP

Here's some info on whats inside

Turn it off, then on again.
SSH into the pi
Locate the CGminer folder
Create a .sh , name it to whatever you want (nano Overclock.sh  <-- just a example)
Add:

Code:

sudo ./cgminer -o "1" -u 2 -p bac --no-submit-stale --tempCut 70 --real-quiet --queue 1 --cs 9 --stmcu 0 --diff 5 --api-listen --api-network --A1Pll 800


1: Keep the ", add pool adress
2: Wallet or Username, depends on which pool you use
800: Default clocksetting, you can push it to 850Mhz but no more.

Save the file
Now you need to install screen for the pi, to keep the resource running even when you logout of the pi.

Code:

sudo apt-get install screen
screen bash


Now you´re in screen
Locate the CGminer folder
Now you need to run the .sh

Code:

sh Whateveryounamedthefileas.sh


Press CTRL + A + D to close screen
You´re still connected to the pi via SSH.

Code:

Logout


Now you´re not connected to the pi anymore and your Dragon is running the chips in overclocked mode.
Don´t connect to the web frontend! (If you do, you need to start over from step 1 again)
Check your hash status via the pool.

IMPORTANT:

If you got the 32 chip version it´s already clocked to 900Mhz (Instead of more chips they used a little more expensive components to handle the over clock, but saved a bunch of money since the A1 is more expensive). DO NOT EVEN TRY TO OVERCLOCK. Add blades instead.

If you got the 40 chip version you can push it to 850Mhz as long as the unit is in a cold room. The 850Mhz setting makes the Dragon pull 1000-1100 watt, so don´t expect the stock PSU to survive to long (unless you got the 2x650w psu version) but should give you 50-100Ghz more to play with.

If you turn off the unit or experience power outtake, just start screen on the pi and run the .sh again and you´re back on over clocked chips again.

Say thank you and send me a beer here: 1Nm46UJo57NAuwA9XdAoaYQpUk4Phg2Ueu

[Suave]

Still waiting on my 4 units.

[Cheshyr]

Still waiting on my 4 units.

Your units were pre-authorized through US customs at 10pm yesterday.  I would not be surprised if you received them tomorrow, although I can't promise that.

[Cheshyr]

There have been reports of high power usage on these units, after the move to 32-chips.  After some badgering, they admitted that the unit can draw up to 1080W in some cases, and that they upgraded the power supplies to accommodate.  If what they claim is true, the included power supplies should be 1200W power supplies, not 1000W power supplies.  So, good news, bad news.

We've run into an issue with customs in Europe.  These units do NOT have a CE certificate.  In this case, a refund is being issued.  I don't think we'll be accepting orders that ship to CE-requiring countries in the future.

I have one unit that draws 1050 watts at the wall (measured using a Killowatt), and another unit that draws 1170 watts at the wall!

Also, both of my units contain 1000W power supplies, so the vender is full of shit. The power supply model number that is included is a Grand GW-EPS1000BTC(90+). I'm not happy about these units containing a 1000W power supply and drawing well over 1000 Watts. Be careful, folks!

The unit that draws 1170W contains 4 blades that have 6 pin PCI-E connections, and the unit that draws 1050W watts contains two blades that have 6 pin PCI-E connections and two longer blades that take 8-pin CPU cables, which is odd. I'm not sure if these units contain a mixture of old and new style blades, but that also makes me a bit nervous considering the over clock. Why does the unit contain two different types of blades?

Here are some other notes:
- The cases were fairly banged up when the units arrived, but they seem to hash ok. One of connections to a blade came out during shipping so I had to plug it back in.
- These units are very loud, which is not a huge issue for me since they are in my basement storage room, but could be an issue for others.

[Cheshyr]

If they die, let us know, and we'll take care of it.  The vendors engineers keep trying to reassure us that despite the discrepancies, the units work fine.  At this point, all I can really say is 'let's find out'. 

[kendog77]

Upon further review, it looks like the shorter blades with 6-pin PCI-E connectors are rev 1.2, and the longer boards with 8-pin CPU connectors are rev 1.1.

One of the units I received has two rev 1.1 boards and 2 1.2 boards, and the other unit contains 4 rev 1.2 boards.

The rev 1.2 boards appear to draw more power. The mixed rev 1.1 / 1.2 unit only draws ~1050W at the wall, and the all rev 1.2 unit draws ~1170W at the wall.

Wow.... hungry units

Yes, I am very disappointed by the power usage since these units were advertised at 960W at the wall. The vender, lketc, is shady as hell, and I won't be ordering any products from them in the future.

- They switched the number of chips per unit from 40 to 32 without updating product specifications.
- The overclocked units are less efficient and use more power than advertised (actual usage is ~200W higher than advertised).
- They shipped units with 1000W power supplies when the unit draws ~1170W at the wall.
- They shipped overclocked units with mixed rev 1.1 and 1.2 blades. The rev 1.1 blades have a wire soldered from the board to the power cable that looks like it's a voltage hack.

I'm not confident that these units will last long.

[Cheshyr]

For what it's worth, the 5-module units did perform in the 880-960W range, but the recent changes to the design were rather drastic.  We'll do what we can to support everyone as we appraise the performance and reliability of these unexpected new specs.  If you have any questions or issues, don't hesitate to contact me.

Despite all of my complaints, the units have been stable hashing at ~1TH each for over 12 hours, so I hope they continue to do so.

I did swap out power supplies on the unit that was drawing 1170W because I don't feel good about a 1000W power supply drawing 1170W 24-7.
