Hello everyone i follow this forum from first pages, happy owner of 2 newpac since two years for fun.
They worked fine@275 mhz. on my Pi3 B+ Buster OS, cgminer, powered USB-hub, and Arctic usb fan.
But from 2 day ago have some trouble of frequency...found 0 chip(s) or frequency jump to 200 Mhz.. im going crazy
I tried to many solution: change usb port, replace Newpac termal paste, update cgminer, downgrade the frequency to 90 Mhz... but nothin to do.. Thanks.
