Thanks - I'll try it out - will let you know how it goes
So that means they just used a biger blades and put on them 16 chips instead 8 as in the first versions.
Then that means the image I posted is exactly the one you're looking for - go ahead and use it.
Just be careful when tweaking the voltage - I beleive I have posted a reasonable settings in the thread.

The 1.5T image should not be compatible with these since they have 6 blades / 10 chips.
If you don't find any suitable image go ahead and try the one from my post.
How many control boards are in there and how many cables are plugged to the control board (except these from PSUs) 4 or 8 ?
there are 8 control cables running from the control board.If you don't find any suitable image go ahead and try the one from my post.

2 cables on each blade - 1 at each end

yes there are two psu
the black one is 1150 watt max and the silver is a hp one at 910 watt max ?

Where did you get this miner from? have you ever had it working?
Assuming it's 8 blade A1 and not underclocked, a 910 watt will not cut it. I did not notice that was a PSU the one's ive seen have two matching ATX power supplies when they were new.
my mistake its rated 1300w at 200v-240v (910w at 100-120v) not matching no - i assume its been bodged/customised.
its bought second or third hand as spares repairs -
the blades all light up and the fans work -
the pi was shot so i replaced it -
need the right software as what was on the sd was corrupted.
and should hopefully get it to work
So, based on your findings it might be a different kind of Dragon 2T, I've seen such modifications in China.
4 blades with 16 chips is the same as 8 blades with 8 chips. Original Dragon 1T was 5 blades / 8 chips and later versions (overclocked) were 4 blades / 8 chips.
The problem with the software I've posted is that it's for 8 blades / 8 chips or 4 blades / 8 chips (always 8 chips per blade).
In your case of 4 blades / 16 chips - I am not sure it would be appropriate to use it.
If I were you and I don't have any other option I'd try it after all.

I have a copy of the 1.5T dragon if needed I believe. I still am a little confused with machine I don't think 900 watts will be enough on one side.

I beleive that the image I've uploaded is not suitable for your miner. It has to have 8 blades to be compatible. Can you post some pics of inside the miner ?
If it's a 2TH dragon it is 8 blade. As far as I know they did not make a 4 blade model that achieved 2T.
there are 4 blades with 16 chips each 28nm
I have a feeling it might be a 1T looking at it. Are you able to read PSU and see what it say's in watts? 1100 or so would be a 1T. If you had a A1 2T it would take 2 PSU's most likely.

hoping to find the cgminer for the 2th/s dragon - 4 blades
You're welcome. Just post after completing the first one so I should know if everything's fine.
Here's the image from the screenshots above for Dragon 1.5T.
File format is .imgc - [compressed image] - you can use HDDRawCopy for writing on SD card.
(the link will be available the next 120 hours)
Cheers.

Not sure the one I've uploaded is the same as on the pic, you have to test that by yourself. If it's not I'll have to extract the image from the miner's SD card - that would be the only way. The one I've uploaded was the last official image on their website and I thought it might be the same - never tested. I wonder why would you try to "have some "extra" juice" these days at current BTC prices. I would rather go other way round - underclock (of course it depends on your electricity cost).
if it's from the website then it;s not the one you have. greatly appreciate if you could extract it out.
many thx again.
most likely underclocking it to reduce the huge amount of hw errors. like i said earlier will have to test it out and see which direction it favors.
