These Gridseed blades are hashing at 5.6 MH/S (2.8 MH/S per board--two boards are in each blade) at the factory settings (not overclocked) and use about 140 watts of power per blade. Your hashing rate may vary based on the quality of your power supply, the quality of the power in your area, ambient temperature and etc. They are rated at a nominal 5.2 MH/S so you should get at least something close to that. This item mines all SCRYPT coins including Litecoin, Dogecoin and etc. I have added two copper heatsinks (one on each board within the blade) over the VRMs to keep them cool--they are the hottest part on these blades and are notorious for overheating (see pictures). The blades are 'in hand,' working order and ready to ship immediately. The units come with: 1 Gridseed Blade with two integrated mining boards with copper heatsinks on the VRMs 2 usb cables 1 6 pin PCIE cable with two gridseed power plugs--one for each board on the blade Original factory box and packaging You will need to provide a power supply that can provide at least 140 watts per blade over a 6 pin PCIE connection--the same connector used for power on most graphics cards. Most standard PC power supplies have one or more of these connectors. You will also need a controller (Raspberry Pi or PC with mining software).
