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.
