You're welcome. Just post after completing the first one so I should know if everything's fine.

hoping to find the cgminer for the 2th/s dragon - 4 blades

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.

well maybe its not a dragon ? check pics - see if you can tell what it is
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.

[renbit]

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.

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.

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

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.
2 cables on each blade -  1 at each end

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.

[renbit]

Thanks - I'll try it out - will let you know how it goes

[sueche]

Sure, if everything else is OK it should work.

I have one of these A1 terminator 2TH miners. It has only 4 pcb-boards but 8 connection cables.So 8-board fw should be fine.Here is screenshot of the original fw.

Thanks for posting.  Very interesting as far as an A1 firmware.  Seems they gave you a lot of control.   Which is very nice.  Might even be able to find a decent under clock.
