Hi, how you have obtained 3.65 GH? Have you used mcp2210 usb to spi o other chip? Thanks
The 3.65+Gh/s per chip requires a xcellent cooling for sustained and long term operation.
To get said performance each chip will need to be supplied with 3.75-4A @ 0.96-1.075V with very low ripple voltage of preferably pk-pk less than 15mV
