2. 8-chip cards that were supposed to give more hashrate per chip using the same 30Amp power regulator, this design failed !!! the new PCB was designed as 2 layers and it generates too much noise to connect 2 h-cards in one bank ... so we can use such cards only in the last position of the bank.
3. provisional 5V string designs [no power regulator], this is a very promising design, chips run very clean and fast, but require cooling. If this is not provided or if it fails, chips heat up, leakage increases, chips consume more power and heat up more and melt and burn finally http://150.254.111.246/img/S7300314.JPG, http://150.254.111.246/img/S7300316.JPG ... the chips don't have any thermal sensors so I am still thinking how to detect such problems using the hardware we have.

and where you later commented that it was an experiment that went out of control -
It's an experiment that went a bit out of control.
The latest scientific explanation I heard is that
"the boards don't like women." Not really sure
about that though:)
intron
So basically - is it the same design? If so - what has been done (and was there anything done) to avoid the same outcome as tytus' ?
And just out of curiosity - are you guys going to be publishing the design schematics?
just jk.
