I have added some old posts, about my first USB Blockerupters and some other stuff. It’s written in Dutch by the way (I am not gonna translate them 🙂 )
Update December 11th:
Today I tried to tune the Hashbuster Micro a little more without overclocking it, just a “hardware” tweak. I put some non-conductive Thermal Paste between the heatsink and PCB.
- Disconnect the power- and usbcable
- Unscrew the 4 screws on each corner where the fan is attached to the pcbspacers (the fan holds the heatsink in place)
- Simply remove the heatsink
- Put nine dots of paste on the “golden” squares (that’s where the chips are)
- Place back the heatsink, press it lightly and move it around/side to side a little so the paste gets spread
- Put back the fan and tighten the 4 screws
- There is a change that some thermal paste leaks through some very little holes in the PCB. You will see some “worms” on top of the PCB (where the components are). Clean it with a dry cloth.
- Reconnect the power- and usbcable and start mining again
Now you should see some temperature drop. I my case temperature dropped from about 45 degrees celcius to a 30 to 33 degrees. Maybe I used a little bit too much thermal paste, I think if you half the dots you see on the photo it should be enough 🙂
This is a short manual how to install BFGminer version 3.8.0 on Linux for the Hashbuster Micro 20+ Ghash/s (bitcoin)miner. Tested on Debian Linux 7.2
