Can you make a daughterboard for the A1 chip or one like the A1 hashrate?
With one bitfury you never come to ROI.

I think the second board with ddr3 ram and artix7 100k could be usefull for litecoins. But this board is in prototype status.

I have an artix7 developer board but its not faster than the sp6

First chip OK

So I think the sencond chip is trash

Asyring:

We have improved now all the shippings. Unfortunately, the shipping time does not depends on us.  Now we offer a true 24h shipping service as we have UPS shipping, but the price is higher.
All the support related with the 1 chip board is on this thread. Just ask your specific question and provide as much information as you can, like pictures or how did you proceed with the connections. For instance, saying "the chain doesn't work" does not help too much.

We provide the specific version of the software we use. It may be an old version, but we get the best performance with it. We have also posted some alternative and even newer software like chainminer.

The performance of the board depends mainly on the core voltage and the software setups. 2.5 Ghps should be a reasonable performance for this boards. Most users reported a good performance.

We understand your complaint. Just post as much information as you can so we can help you.

OK my questions:
- which values are possible for osc6[8]?
- whereis the set_freq() value in file? Not in this version!

Archivo spidevc.c, línea 96, fragmento "speed=xxxxxxx" ajusta la velocidad del spi en Hz. Una velocidad de 5 Mhz es un buen punto para empezar.

Archivo libbitfury.c, linea 297 edita la frecuencia mediante la función definida en la linea 204.

Code:
set_freq(52);
           
- why found chainminer 8 Chips?
- why is my max hashrate at approx 3Gh/s with two miners?
- and chain is not working means that the setup doesn't produce the double output with two miners!

My setup is like this:

As PSU I have a lab-PSU which is at 6V and it takes with both miners 0.54A.

Sorry Minerfactory never again!

48h shipping was 10 Day shipping!
No Support!
Old Version of software!
No support for new software.
2.7Gh/s expected 1Gh/s is realistic.
after modding 2Gh/s with one miner.
The chain doesn't work!
Lower hasrates with 2 miners.


Sorry that was the first and the last time I odered at minerfactory.

Today I want to try to connect the second miner again.
The second miner has the factory 10kOhm trim resistor.

I think I have 5MHz for the SPI.

With the testingtool from bitfury I can't see any difference between 4 and 5 MHz. at 10MHz the rate drops.

So I resolderd yesterday the trim resistor to a 4.7k resistor. Now the 0.9V is at 0.86V and I get a hashrate of approx 2.3Gh/s with one chip.
This is more than before with two miners.
When I connect the slave miner the rashrate goes down I don't konw why. Has someone a clue?

I think the VRM has not enough power. I'll try to power the chip with an external lab psu with 0.7V.

I'll report the results.

I need some help.

I've connected two Bitfurys to my pi.

When I start cgminer I have a avg. of 2.357Gh/s.

I think thats to slow for two miners.
If I connect only the master I get approx 1.4Gh/s.

Where is the problem?
I have a big fan that cools the miners.

I checked also the Voltages on board and all voltages are in range.

So what can I do?
