Yes indeed, it's not worth that kind of language and behaviour. Patience he will sort it .

In the mean time, ignoring the user prevents it from ever being noticed again.

Hello Martin,

Is is possible to have a tracking number for those packets (Order Ref EJYKOZQDX) ?

So,
All 10-th feb orders are packed.
Part of them went out of the door.

@marto74: All 10th Feb orders shipped?

My Status still says "preparation in progress" as we know from Gator-hex there could be the status "shipped"

Did you see the BitMine A1 1GH/W @ 200GH Video?

http://www.youtube.com/watch?v=91MuwGOgRFo

Are these the same batch of A1 chips we got, or are they a later more efficient batch?

Just wondering if my Hex8A1 will run 1GH/W @ 200GH or if later batches of Hex8A1 will be more efficient?

Hex8A1s not arrived yet so still in speculating mode.  

UPDATE: Oh, I see they use 12x A1 chips per board to get 200GH/200W so not going to be that good with 8x. Aww. 17.5GH a chip.

17.5GH x 8 = 140GH @ 1GH/1W I estimate on the Hex8A1.

No, 12 chips are for the rig boards, desk boards have 8 chips,  clocked at 800MHz for 25GH/s per chip, 200GH per board.
That video is showing a Coincraft Desk unit, right?

Some hints for you Zih (and for the rest waiting for their boards to arrive).
1. Set you pool hex8 worker to mine at predefined diff 256 or 512 - will give you les rejects about 0.15% . The key point is to avoid adjusting your diff to often. The higher the better
2. Set diff-to-one 1 -   watch it closely HW error % and find your sweet spot in terms of clock and voltage
3. Set diff-to-one 0 - default value for a production run - which will give you less HW% and big speed variation, BUT you gonna have x diff less USB reads better usb communication. You are not loosing/gainig Hashrate. you are just suffering from variation. Probably you are getting very small amount on top because of reduced USB reads which are deducing USB CRC errors  
4. Wait for a day and post nice looking screen shot
5. If you are inpatient and do not want to wait use diff-to-one 1 It is ok even for production run
6. And post again
7. Finlay when you are done ssh/screen disable logging --quiet

Thanks loshia , this is what i need.
I will follow your way by setting at lower frequency & voltage then let it run for 24 Hour before push it to 260

I will get upset if you do not post something like this I am jocking of course do not push the board too much  

My reject rate is little bit high due to my primary pool issues and moving back and forth to backup/primary, besides guild sucks in terms of rejects for me personally
this is with Set diff-to-one 0 - i am testing it and it is looking good   with tplink of course
TO ALL - Such high clock and voltage values are not recommended Use them at your OWN RISK!!!!!

[Beastlymac]

Shame they have sold out the pre production run. I was interested in one. If anyone is looking to sell one at a fair mark up i would be interested.

  Honestly I can't wait to post

[stiffla]

so I just received 3 boards today.

I opened one board to check it and one fan is broken on the edges and some nuts are missing to keep the fans on the board....it is not a deal breaker, but the nuts should have been there

I will test the boards in the evening with my less powerful 40A PSU (still waiting on my new ones).
How do I have to set clock and voltage? Or should I just try to decrease the voltage until it is stable?

Thats really cool if it's the same chips, and they only used 8x per CoinDesk board, I might see 200GH for 1GH/W then?  
That's a lot of power cost for 60-80GH Turbo gain.
