Thanks for answering the question, loshia I am not above giving credit where credit is due. I am asking because I have my own curiosity as well in this. AMT is not the only miner I own. And getting some other options is nice. Thanks again for the reply.

So out of curiosity the numbers achieved what settings were needed to get those?
What settings were required...and can they be sustained without burning out?
And are they recommended?

Welcome contributor,
To contribute to your question first thing
https://bitcointalksearch.org/topic/m.6597849
So you will need a fire man arround like usual with amt crap Grin

Now if you are brave you will need
270 clock and 1050 mv whatever this means to you oh yeah and 40 amps at 12 volts.are your two higher degrees enough for this info?. If not look at cgminer screen if it is not helping you Zipkin poserkoto will explain for sure. When time comes of course Grin

it is a matter of weeks Grin

just a few more
Ask for your money poserkoto Zipkin is gona deliver crap as always
If you Contribute this info to amt thread I will own you Wink

Just measured the power draw at the wall (240V) for 4 x Technobit HEX8A1 - 260GHs Coincraft A1 units:

Pictures can be found here: http://imgur.com/a/mRbMZ#4w7cdKp

1730W = ~1000GHs
1730W / 4 = ~433W each (250GHs)

Code:

0: HEX8 0 : 270 1000/1009mV | 777.0G / 262.8Gh/s
1: HEX8 1 : 270 1000/1006mV | 74.51G / 262.9Gh/s
2: HEX8 2 : 270 1000/1006mV | 354.7G / 255.4Gh/s
3: HEX8 3 : 270 1000/ 999mV | 266.6G / 275.5Gh/s

How the heck is that possible?

That is overclocked at 1v, I assume, yes?
Consuming 1.7W/GH... That would cost me over $5000 a year, just to run it! In addition to the cost of the unit.
(Just thinking out-loud, observations, not complaining.)

Where the heck did you find a 1800W PSU?

No shit isawhim Wink

No seriously I will keep my promise and stop to "contribute" to amt thread anymore. poserkoto Zipkin deleted my post from amt thread of course. Opium2 will take care of it Grin

In general you will be able to get 1.2 the from 5 boards Technobit originals with real heatsinks. You need just a little bit of over clocking
We discussed so called psu issue and grounding if your remember?
Back to your questions yo are needing about 30-35 amps per board at 12 v to get 1.2 t the from 5 boards
As we know poserkoto Zipkin will not ship you six boards Grin

If I were you I would split my setup over two psu's with two tplinks
You are good with numbers so you are the one to decide. I will strongly suggest
1. To ask for refund from poserkoto Zipkin
2. Or eventually if you happen to get someday Technobit boards without amt engendering touch Grin

To run them in more relax manner on two psu's
Yeah an prepare about 700 usd for psu just in case

I do not remember you getting miners from us Wink

read carefully
it is 1W/GHs in standard mode
it is about 25 GHs per chip or 200 GHs per 8 chip board.
And just FYI the board design can change the power consumption in the range of 5-10%.
So it is the chip !

I have not gotten a miner from you yet... I had not said that I have...

I am aware of the A1's power consumption and levels. I was simply questioning HIS use, in the post.

Looking at the other post I quoted... ~~Nor apparently does he have your miner... That is not your boards, that was the power draw of the avalon2 miners. Unless you guys make Avalon2 miners, and Avalon2's have A1's on them now.~~ (I also see he has two separate PSU's... He made it look like only one PSU.)

~~I should have realized that was not the A1's, or, well, not your A1's... Not sure why he posted that here.~~

I came, because this version of the A1 boards are being offered by AMT, as a substitute for the boards they are having issues with. Wanted to get an idea of what I would be getting, before I told them to ship me my miner.. um.. your miner... xD

I am more interested in loshia's power consumption now, looking at his setup. Those are the normal operating voltages I am familiar with.

EDITED: He does have these miners... They are just further down the line in the photo's. That guy has every miner in existence, lol.

Try underclocking them to 230/860 and run cgminer v4.2.3 and see if you can replicate Ioshas results on BTCGuild!
Apparently we all get the same boards and chips are random but that should get you pretty close to 1GH/W. You can run quieter fans then too. Wink

2014-04-26 19:14:23    Hello !

i just send the Miner for RMA
because i want to buy another i choose to "upgrade" this RMA Unit to an HEX8 260 GHS Version.

following URL :
https://bitcointalksearch.org/topic/m.6407336
--------------------

Mhhm my original Order was :

Total products : 499,00€
Total shipping : 32,00€
Total 531,00€
Shipment MARCH 2014    130 GHs HEX8A1 Coincraft A1 miner    1    499,00€    499,00€

What about Pricediscussion ? i am willing to pay 100 Euros more ( 499+100 ) thats 599 Euro for the Hardware.

Can you the send me then back the 130 RMA as 260 Unit ?

Otherwise if i had to pay more the send back my 130 Unit

Hope my English is not so bad that you understand what i mean ;-)

Has anyone successfully tried 270/1050 for extended periods of time in a ~23 degrees C room? Running at 260 seems to work fine, but this saved me after my tl-mr3020 went crazy: https://bitcointa.lk/threads/cgminer-windows-build-for-technobit-boards.298736/

[edit] btw @ 260-1000 I have 0% hw errors, does that mean i can safely try 270/1050?

The test is for current measurement only. I only run it for about 5 minutes since the heatsink become very-very hot.

You can see the current usage is very high for only 10 GH increment LOL

Hi thanks for replies and info, it helps.

so on 130 unit there are 4 chips?

also why are there two 6 pin PCI-e and what are the terminals ?

what info have you based power (12v 17amp) on?

I would like to ask Marto what sort of power supply he would use please?

Yes (lol) i have run two 130 boards on the 300w PSU conected like something out of film adaption of Jules Vern novel.
one PSU is not working now (over heated) in an other 12v line wire began to melt at hexminer voltage 1000. I got a few of these 300w PSU for cheap price (10 euro each), yes u get what u pay for some times.

but it has meant I did not get chance to break more expensive PSU ( I am a beginer really)
When I ran the two 130 units hexminer voltage "890" PSU heating up was less and ran 4-5 hours but with low hash rate
about +/-100gh/s.

so for correct power supply I should know all factors of power requirements of parts on unit eg. chip, fans etc.
ok thanks again and if you can help with further infomation that would be ace!

EU40Niner

After all the explanations i am wandering how you still are not on fire

Listen to zich
Chips need power - that is why two connectors are there. Zich have measured them in the past

In short for eight chips measured by zich

Here is the result on 12V rail:
260/1005 = 33 A
265/1030 = 37 A
265/1040 = 38,5 A
265/1050 = 39 A
270/1050 = 40,5 A
You can go lower of course that is OCed Wink

So divide this by two and add 15% safety margin at least for 4 chips

Has anyone successfully tried 270/1050 for extended periods of time in a ~23 degrees C room? Running at 260 seems to work fine, but this saved me after my tl-mr3020 went crazy: https://bitcointa.lk/threads/cgminer-windows-build-for-technobit-boards.298736/

Just bought a 8A1 for 400 euro's.
it is working fine, but the two fans are not working when connected to the board.
I do supply them external now (connected to same psu).

Does someone know why the board does not supply them (maybe it has happend more often)?

If anyone else (preferrably EU) has any hex8a1's to sell, We can talk about this price range I'd like to get one or two more

Hello,

A bunch of AMT customers have received AMT systems that are non-working.

Would it be possible for us to send our boards to you to be re-assembled into TechnoBit boards?

You will just have to remove the surface mounted A1 chips.

Is this something that is viable?

All of the AMT customers execpt melbro did recive a crap. not a bunch all exept one!
Are you ready to pay shiping back and fourth + 1month delay + service + pcb cost?
If yes then somone can comment if it is possible at at in technical terms
Besides you do not know if chips are working at all
that is noncence
The best aproch will be to order populated board without the chips and do it localy.
Nonworking chip in the beginning of the chain can make all the rest not to work
And finaly cheaper will be just to order real fuly populated board which is working fantastic Wink

That is a thought, how much for a fully populated board without the A1 chips? We can mount it ourselves.

Marto can you comment.

You can order assembly service and to comment in mail or pm that you want them without asics
