Has anyone received their miner ?
You cannot magic 200GH out of thin air without adding more watts and it's an exponential relationship so it will require more than 20% extra watts.
Overclocking is primarily a linear relationship. Overvolting is exponential. If they are simply overclocking (and not overvolting), then the watts per GH/s will be mostly unchanged.
If you don't increase the voltage, with the clock increase, you will just get hardware errors and rejects.
thats semi-true. You could probably overclock linearly for about 10% before errors begin to arise and then you must increase the voltage slightly to continue clocking higher.
The power draw should be more, but its likely not much more
Typo should have been...
40 chips x 25GH = 1000GH = 0.9W/GH
32 chips x 25GH = 800GH = 0.9W/GH
32 chips x 31.25GH = 1000GH = more watts/GH!

I have Hex8A1 boards running 8x A1 chips @ 250GH and they're way over 300W each. Assuming it's a better batch of chips. 4 x 300W = 1.2W/GH
I stand corrected. You sir were correct.
They might gone over the head trying to make 1TH miner cheaper. Soon we will read reports of these units mass failing.Quote

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!

They went worse. These units will not last.
IS the new Design 3U or 4U ? also is it available with the current batch?
So anyone here successfully order from the site in the OP?
How did they confirm your btc payment?
Btw, since they dont use services like Bitpay, what exchange rate do they use? from which exchange?

Think about what you're saying...
40 chips x 25GH = 1000GH/900W
32 chips x 25GH = 800GH/900W ??
32 chips x 31.25GH = 1000GH/more watts!

Sorry I was not that clear. Need to improve my English, thats was very bad post. I am saying more watts per chip yes, still 1 less blade take less watts in total. They wont go from 180watts per blade to 300watts per blade, no point. I put killa-a-watt to my unit today and it was pulling 878w from wall with 1TH ok i have swapped the chinese 1kw psu to FPS Aurum 1.2kw psu which might run bit more efficient. Also my fans are taking less watts. I swapped silent ones.
40chips x 25GH = 1000GH/900W 5 blades
32chips x 25GH = 800GH/720W 4 blades
32chips x 31,25GH = 1000GH/+900w 4 blades lets say 25% increase in hashpower and 30% increase in power consumption. Could be possible.
32chips x 31,25GH = 1000GH/1200W would be 25% increase in hashpower and 68% increase in power consumption... thats too much. My bet is closer to 1W/GH or under.
That unit cant draw 1.2kw or it's fail in design. No point making it. I quess we will see soon. I have one coming I assume it's new design.
I am just speculating here with no better knowledge. Lets assume I am wrong. Maybe we see 1200w psu there.

^watts at the wall was mentioned. this means that the measured power is about 10-15% more than what the PSU is putting out (probably around 85% efficiency)
From the picture I count they are making this new model with 4 blades. That is 8 chips per blade 250GH/blade ~31.25GH/chip = 1000GH unit with around 900w power.
I doubt the new one will run at 0.9W/GH @ 31.25GH a chip, probably more like 1.2W/GH, you cannot get more GH per chip without using more power.
I see they've finally figured out it's a 30/70 package and they need a heatsink on both sides of the chip.
I'd still rather have the old one and pay a little more to save my power bills, but I guess for people who want higher density and lower $/GH this is better.
More power per chip yes but also 1 total blade less. Total number of chips is 20% less i still think it's around 900w as they advertice.
Original unit was like 200GH / 180watts per blade, i have 1 onit its total draw from wall is around 900.
So if new design is 250GH / anything less than 240watts / blade keeps the unit still under 1kw total. I really doubt they would improve blades desing to sustain +100w more powerdraw thats too much for the power lines. 1TH/1.2KW unit dont make sense
We will see.

has anyone figured out how to overclock the "gen1" blades? can it be done? should it be done? Should I add a power supply?
I cannot find any info on the overclocking. Oh, and if someone can figure out the logo on the LCD screen....Id pay for that.

Start with extra psu. Good chance something breaks.
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)

New more compact model. I still somehow liked the old one.
This is the source for Dragon miners you can again see their logo in the LCD

Their first design was 25GH/chip and 5x 200GH blades. IF you own any of those early models the MCU unit can run 6 Blades. So you can get 1.2TH - 1.5TH from those units. Thats why i like the design more. Much room for 2 PSU units, much room for ventilation.
DO NOT OC THE GEN1 BLADES. THEY ARE MADE TO HASH 200GH NO MORE!
This New design is made more compact, also saved 1 fan. Price could to drop sub 2000$ while Innosilicon drops chip prices. That unit cost them nomore than 500$ including the Great Wall 1000W psu ( good 1kw psu from China ) ex. chips.
This design beats Antminer S2. Compare 32chips to cool vs. unseen Antminer S2 and 210 chips
These are cheaper.
This factory is challenging Bitmain. They could be shipping out 1PH /week lol
See how Chinese pool hashrate is growing.
ps. whats on that whiteboard
-edit- Can someone write up Bounty post to make Minepeon image to this Dragon miners Raspberry PI. i would gladly pay on that service. There is fancy LCD module too.

Are these guys the company that manufacturer the dragon machines?
Will be interesting to see if this English site works

Yes, look at any of the the Dragon miner resellers pictures, they will have "lketc" on the display. You won't find it cheaper than from the source.
as ive stated before that sites hosting malware.. visit it if you want ...
You talking about a different site?
https://www.virustotal.com/en/url/45e7cc782d8c57113907f502adee992659824e1b963fc169e500d84173124849/analysis/1395586437/
www.lketc.com Looks clean to me.
He's thinking about one the reseller sites.
