I have 50 running at 90Gh/s total. Two throw tons of hardware errors. Shares found on same two are very low even though hashrate is reported normal.
These things run very cool. Begging to to overclocked. Hoping to be able to tweak in the future.
Pictures?

I posted above how it is possible to hardware overclock. Firmware over clocking might be available in the future I just don't want to cause more issues that would then need to be fixed.
