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

[DimensionsOfHell]

Hey quick question Dave,

I got the tracking numbers you sent this morning, but it still only shows shipment information received. Do you know if it's physically been shipped yet? I know it's a stretch of a question, just wanted to ask in case you got info on it.

[Cheshyr]

It's my understanding that DHL out of China can sometimes take a little time before the status updates, even after the package has shipped.  All items have shipped.

I just got the rest of the tracking numbers about 5 minutes ago; emails going out now.

[DimensionsOfHell]

I just thought about something, Dave, the miner you had was the 40 chip version, which was not OC but these newer units are the OC 32 chip version. What guarantee do we have these will survive the long haul?

From what I know, these are the "imitation/fake/knockoff" A1 chips these machines are running, and now they are overclocked. I don't feel too good about the longevity of these machines. I hope these will at least run 7-8 months without issue. I would've felt more comfortable with the 40 chips at lower clocks not pushing things close to the limit.

[Cheshyr]

Recent information has made me believe these aren't knock offs or fakes. There is a warranty, so I don't think you need to worry.

We all would have been more comfortable with the 40 chip units. This is what the vendor decided to ship after taking our money. We're going to do our best to take care of everyone, despite the incidentals of this group buy.

Are they giving you any spare boards for RMA issues? Or do we need to deal with them?

As mentioned early in the thread, we're making arrangements to have spare parts available in the US, so you don't have to go back to China.

[Cheshyr]

DHL Tracking is claiming the units were picked up this morning.  We gave them the units by the end of day March 20th, so I'm not entirely certain what's going on.  I'm in the process of following up now.

[Cheshyr]

I followed up on the shipping updates...  Hong Kong customs is seriously backlogged.  Once they clear customs in Hong Kong, they should arrive pretty quickly.

[Suave]

And if they don't arrive before the guaranteed ship date?

It's DHL that's why. Someone from another group buy shipped me something Fedex earlier today (EST time) and it will be here Monday....

Quite annoyed...

[Cheshyr]

Yup. Same.

I don't have a response to your question regarding ship date and arrival date.  I've provided best estimates and email updates within an hour of having them myself.  

edit:  DHL is what we had, and DHL is what we have always posted as intended shipping method.  We've had other poeple ask if we could use another carrier if they were cheaper, but in all cases they were more expensive.  Next group buy, I'll pass on the extra $100 to you guys, and use UPS or Fedex instead.

edit 2:  It's only the 22nd.  There's still a very good chance it'll arrive on the 25th or 26th.  I understand the annoyance with the DHL reporting system, but 3 days from Hong Kong to Eastern US is not uncommon in my experience.

[Powell]

Once it makes it out of hong kong it is usually 2-3 days.  Hell if it reported leaving and customs in the US on Saturday (and passes through) you may even have it by Monday.  I have had this happen before.

There are 2 GB's of these machines that the factory sent out at the same time and of course HK customs is overwhelmed.  I just do not like DHL for other reasons (even if cost is more for FedEx/UPS) years and years ago they brought out their special teams and managed to kick a 42 yard field goal with a car part to our front door.  All we heard was a thud.  Thankfully part was metal, but recently most of my DHL things have been ok when they come in.  I just prefer Fedex and UPS because I do have tracking and delivery notifications setup for me.  Plus autosign for package, etc.

[Cheshyr]

5 shipments have been received by US Customs.  2 have left Hong Kong and are en route to their specific country.  6 are still in Hong Kong customs for some reason.

[Suave]

Have the 2 that have been released had their DHL tracking updated?

[Cheshyr]

All but two packages have left Hong Kong.  These two were also the largest orders, which is a bit frustrating.  The tracking is up to date.

I got a unit before this batch with 5 modules.  How do I overclock it?

I'm not quite sure how to overclock these.  I would assume you need to SSH into the Rasp Pi and modify the cgminer config file, as mentioned by someone else in the thread.  Anyone else able to help here?

The instructions I got:

"As the machine does not open interface for overclocking settings, you need  modify the cgminer parameters listed in /boot/www/index.php, it is said that the hash rate could up to 1.2T with the sufficient power supply after overclocking. We are working on that to evaluate whether it is possible"

1.2Th is impossible and the reason why you got no instructions on how to overclock the Dragon units is because it will go up in smoke if you push it (Cheap-ass components)

This is on your own risk: (aka hardcore miner mode)

How to overclock a Dragon 1Th unit:

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  

EDIT: Thanks for the beer anon! (I like beer, so keep it coming if you feel that this guide helped you to earn some more coins   )

Edit 2: Cleaned the how to up a little. Added some text so now anyone with a little knowledge should be able to over clock.  You can create multiple .sh for different Mhz settings and pools ex Eligius.sh, Bitminter.sh, Ghash.sh and so on.

Can anyone help me? i followed these instructions and I get this error when I try to start CGminer
[2014-03-24 05:50:24] ./cgminer: --A1Pll: unrecognized option

i am running cgminer 3.9.0. i have the batch with 5 modules

[Cheshyr]

Over half the shipments are being delivered today, or have already been delivered.  I expect more precise tracking info during the day today for the other shipments.

Thanks Dave. Your communication and status updates for this group buy have been excellent.

[DimensionsOfHell]

So..... How do i set this bad boy up? Instruction is in chinese... I cant find the IP add to connect

[DimensionsOfHell]

hey one of my miners is defective. It doesn't get an IP address. I just plugged the second one it, and it came right up.

it is possible that it is set to a static IP address.

plug a monitor (hdmi or composite) into the PI and you will be able to get the iP address that way
