Wow a Jala has 2 - 4Gh chips inside and you managed to get more than the physical limit.
Amazing!
my jalas were hashing at 8.7 Gh/s, lucko from BFL contamination board has some firmware hack for that, I met him in Ljubljana (the capital of Slovenia) and he did all the jalas and for free, BTW a real great guy.
the one that had only 8 Gh/s had a bad chip which had only 13 working engine as lucko explain to me. but I went from 15 Gh/s to 25Gh/s, I just wished I could do that when i got them right away....
