GekkoScience NEWPAC (Dual BM1387) USB Miner – 23GH’s+ USB Miner (SHA256) MADE IN USA
All products are tested for non-DOA and confirmed working.
If you run the miners over about 100MHz, use a cooling fan. Actively cooled sticks will use less amperage than passively cooled ones.
Non cooled sticks are subject to thermal runaway where heat will trigger increased amperage draw increasing heat in a cycle until the unit fails.
GekkoScience NEWPAC Dual BM1387 Stickminer
Features 2 Bitmain BM1387, the same chip found in the high-end Bitmain S9.
GekkoScience built a Mini USB miner that will run stock at 23+ GH's using only USB power and can overclock to upwards of 90 Gh's with adequate cooling and a powered USB hub.
It functions through a modified cgminer, which gives you command-line frequency control to adjust the hash rate.
This entry-level miner is good for anyone interested in tweaking and testing stuff, or for anyone wanting to “get into mining” without spending a lot of money or burning a lot of power. It’s designed as a flexible yet affordable tool to learn a lot about bitcoin mining and its hardware. While it's small and doesn't offer the same hashing power as the big pod systems, the GekkoScience NEWPAC is the most power-efficient Bitcoin miner on the market today.
