Topic: Received one silver and one black Avalon... (Read 771 times)
Also, I have the problem on the black machine: for the second time, hashing power drops to about 4-5 Ghps with no obvious reason, frequency stays the same, but the temperature drops to 32-37. Only restarting cgminer helps.... Someone experienced the same?
I also have one silver and one black Avalon, and I see the same thing.
Only 2 temperatures are reported on the silver unit, where all 3 are reported on the black one.
My --avalon-auto speeds settled on ~360MHz for the silver one (after I replaced the power supply), and ~345MHz for the black one.

I ordered batch 2 avalons, 2 pieces, but I received one silver and one black. I suppose silver is batch 1, and there are some differences in temperature readings actually affecting speeds that Avalons can achieve:
I use cgminer's --avalon-auto parameter for them both:
my black avalon shows the temperature for all three sensors: 34, 49 and 51, and frequency is about 340 Mhz, making about 77 Ghps.
my silver avalon shows these temperatures: 37, 53, -1, frequency is about 274 Mhz, making about 65 GHps.
Have in mind that I originally received silver avalon with temperature sensor attached to P4 connector (like on picture), and now it is attached to P3 with above mentioned values, because I tried to make things better. While it was attached to P4, temperature readings were like 37, -1, 53.
It's not clear to me, do I miss one sensor in silver machine? If not, should this one be attached to P3 or P4? And, where is the connector for the first value (37)?
My firmware is 20130723 on both machines.
