So.. I can finally post here Smiley
Started working on overclocking and abusing the Block Erupter Smiley

From what info I have found
"Each chip's rated frequency is 336MHz at 1.05V
The chips work stable and well at 392MH/s at 1.15V. Further overclocking needs proper handling of heat and power supply."

So I started looking into how to boost things up.

Simple start... the soldermask on the back of the board... this will prevent good heat transfer. I am planning on polishing my boards up better
but simply scratching the solder mask off carefully under a microscope

 could be polished up better.

Same can be said about the asic.

very porous and could be smoothed out for better heat transfer to a heat sink.

I started to reverse engineer the board completely.

I have a feeling the speed of the asic is controlled by the firmware in the attiny
I would kill for a full detailed schematic or chip spec of the asic.
Can anyone get me one? Firmware of the attiny would be nice too Smiley
