Title: Overoverclocking the Borg (BE) Cube?
Post by: brush242 on January 01, 2014, 10:18:20 PM
I swear to Jeebus, I saw someone either commenting on, or noting ideas on, how to overoverclock a Cube. Well, then again, I could have dreamed it....

Does anyone know a thread or source for such a thing? I've searched up and down, but needless to say, nearly every Cube thread mentions overclocking almost as often as it mentions the Cube.

Any thoughts? And thank you!

;)  You weren't wrong.  A user here who's had great success with overclocking kits for blades was working on something similar to overclock the cubes, but last I heard he was only getting another 1.5-2GH/s out of each cube (up to just under 40 GH/s) due to heat issues in the cramped cubes.  His method for the blades was pretty elegant - just change out some feedback resistors so that the BE100 chips get more voltage, swap out the oscillator for a higher rate, and improve cooling.  I imagine it's something similar for the cubes.  FWIW, I got two of my v2 blades crunching happily at 14 GH/s with his kits, and they're still going strong.

Anyway, drop sidehack a note/PM here and I'm sure he'll update his progress for you.

Best and Happy New Year!

Thanks Tye!

Was it a lot of work? Meaning, could a guy with a ball peen hammer and a chisel get it done in an afternoon, do you think?
