From the project
NerdQX is a new development based on NerdQaxe++. NerdQX also has four BM1370 ASIC chips, a different PCB geometry, and significantly improved and simplified safety mechanisms.
NerdQX is a new development based on NerdQaxe++. NerdQX also has four BM1370 ASIC chips, a different PCB geometry, and significantly improved and simplified safety mechanisms.
The NerdQX was developed as the world's first multi-ASIC home miner for overclocking, which also enables extremely efficient mining. Furthermore, the NerdQX can measure the temperature of all four ASICs separately and directly, in addition to the existing and somewhat less accurate variant.
