This uses the BM1368 chip found on the Antminer S21 and use the Argon THRML Cooler to keep temp very cool. Purchased from D-Central Tech in Canada. Never been used. Tested by D-Central for 24 hours before shipping. Only unpackaged for pictures. These hash at ~740 GH/s and use around 18 - 21 Watts. These some pre-configured and overclocked slightly due to the massive cooler that is capable of keeping the chip temp way down.

I bought too many and would like to sell two of them. I have this orange one and an black one in another listing.
