Even at 500$ it is still the cheapest option(MrTeal 8 chip cost 300$ estimated without cooling and chris99 240$ but we don't know if it is 6 or 8 chips and without cooling as well)...
Just to clarify that board is for 8 chips.

Our board was designed to support 8 chips without any problem and with the maximum heat dissipation.
I am not an expert, as the engineers of the team did this job, but as far as I know
supply current for the core of each chip is 10A.
BFL power supply is approx 35-40A. that is why supports up to 14GH/s and not much more than that.
If BFL's board provided 80A current, it would be enough for 6 good quality chips - 28GH/s.
EDIT: If BFL's board provided 80A current, it would be enough for 6-7 good quality chips - 28GH/s.

EDIT: now that I have looked it longer it seems that is not. Right? Now looks like a nice board in a making...

Heck, a trained monkey could do that.
Can you send me one of thou them... I would love to have one.Your very early estimate for a 4 chip board was "under $200"
If you compare your estimates with the early BFL estimates, then your figure, of around $500 for a 16 chip board, then you are still on track to beat BFL again.
I'm still working on supply chain so I didn't give up on the price... It is still estimate... If you compare your estimates with the early BFL estimates, then your figure, of around $500 for a 16 chip board, then you are still on track to beat BFL again.

Hi Lucko
Just been reading some of the early posts,
Your very early estimate for a 4 chip board was "under $200"

Their estimates always went up and take longer.
Your estimates go down and the product arrives quicker.
All we need now is 70+ Gh/s from 16 chips and we all win again.
BFL must be very unhappy that a private group can produce a better product.
Why would they be unhappy? You're vindicating their work by using their chips.Just been reading some of the early posts,

Besides, what did your group do? All of the hard work has already been done. Your private group did none of the R&D, they will just take chips and boards and put them together and then ship them. Heck, a trained monkey could do that.

Board for less chips will cost less. And GB buyers and donors(the one that contacted me) will also get a discount of 5$ per chip. Good enough power regulation (needed by this chips) unfortunately cost a fortune. It is more then 30% of that price. We also need to cover R&D costs. They are close to 10.000$ at the moment. One time boards cost a lot especially if they are rush jobs. Different test parts and components also. Also some additional equipment we needed to buy and so on... And quick laying of the chips on the boards also cost allot... We can't do all that by hand... We are looking to get prices as low as possible. I'm looking for a way all the time. But at the moment it looks like we can't take it down unless you are willing to wait weeks for board to be made...
We are talking about fully made board. And we think that it will do 70GH with good chips and 65GH with below average... But that is just a guess. We have only poor quality chips(below all BFL grades) but we still get on average 3,6GH out. So even that would get as close to 60GH...

Hi
Don't quote me on this but the price of the board itself fully assembled will be someone around the range of $500.00
We will have a definitive price soon, but this will give you an idea of what to expect.

Does that include the chip assembly, or just $500 from the factory to you

Come on is a lot of money

I will call him tomorrow since he lost about 600 to 1000 MH just by taking them away from me... He must be doing something wrong... And it looks to be incompatibility with BFGminer. I just did some test. I get less with it too... Pool detects 300MH less on my Jala... I put it on difficulty 1 so I get more stable results... But will run it for longer...
And BTW 8.4 is normal for A grade chips without overclock. And 8,6 isn't that special too. But 8,7 that we did saw on one jala is... It had really good chips...

I know why I lost that GH/s, I was looking to charts in my pool and it seems that the stratum server had some issues and still having them, it was disconnecting and trying to reconnect when I logged to watch, I have to change that pool now.
I tried BTCguild and it was working steady at 25.6 GH/s, but fees are 7.5% I will look somewhere else.

What will be the price of board!?

Hello
Just wanted to give an update. I received this morning a DHL tracking number from our PCB fabrication facility in China. These will likely arrive in 2-3 days, at which time I will post pics on the forum and send a couple boards to form and lucko for testing and I will also send 5 boards to my US based Assembly facility, to have 5 production test boards manufactured.
If all goes well with those test boards (which we expect it will) we will move forward.
- Things left to do:
- Test professionally manufactured production board
- --> Finish web site for ordering and order tracking
- --> Test different cooling solutions
- --> Determine final prices
<-> We will have PCBs in hands in a couple of days
<-> We will have professionally manufactured production boards in 7-10 days (or earlier)
Ill post an update with pics as soon as the boards come in.

OK after almost 3 hours of hashing with cgminer 3.4.0 , the 3 jalas seems to be better working
August 31, 2013, 08:49:03 AM
No it has less engines working since chips were poorly cooled. So it is physical damage... And since it has less engines running it is cooler...
August 31, 2013, 07:25:23 AM
Ok so the great jala is even better then we thought... But there is something wrong with good Jala. It looks like it was not autoconfigure OK. You might think of restarting it... And the bad Jala is also a bit higher then we thought... Nice only good Jala is disappointing... It was probably a bad luck during configuration run...

Ok I got cgminer working, it was a driver issue, now everything looks great, I am getting an Avg. of 25.3 GH/s I will let it hash for few hours than post a screen shot
This is a "shot in the dark" suggestion for your "Bad" Jala, It seems to be constant at a lower temperature but showing error rate 4.6%
Try removing the cover, the temp may drop a bit more, and then check the error rate.
The other riskier option is to restrict the airflow a "SMALL" amount, and see if the temperature rises to the same as the others, then again check the error rate.
I have found on some of my kit that overcooling made them as unstable as overheating.
