Does anyone here know the exact voltage that these chips operate at?
I know the voltage is fixed and can't be changed but what is the exact operating voltage for each ASIC?
from my research they use the same chip (BM1382) in both the s4 and s4+ and the specs are as follows
Chip specs: BM1382
Process Node: 28nm
Package Type: FCQFN-56
Packaged Chip Size: 8mm x 8mm
Number of Cores: 63
Core Voltage: 0.75 V
Core Frequency: 250 MHz
Hash Rate: 15.75 GH/s
Power Consumption: 0.59 J/GH (chip level, and it can be lower to 0.40J/GH by lowering the core voltage)
