ASICs GTMiner V66, V88


GTMiner introduced two ASICs for mining on the Ethash/Etchash algorithm — V66 and V88. GTMiner ASICs are analogues of the more well-known iPollo V1H ASICs.

The V66 model is positioned as a home ASIC, and the V88 model as a powerful industrial one.

We offer full support for GTMiner V66, V88 ASICs, high efficiency and stable profits for mining coins on the Ethash/Etchash algorithm —

Important note! The memory size of this ASIC is only 6 GB, you will not be able to mine Ethash-coins with a DAG file size larger than 6 GB.
