Well, it's quite possible your Jally has B grade chips with some errors. Remember BFL was originally going to use *one* chip to give us 4.5gh, it didn't work past 4 so they gave us full blast singles with two chips. The fact they used B and C grade chips is fair, since we paid for 4.5gh or maybe 6 if we spent the extra $100 or so (which seemed to get us A grade chips as well).
So 7.3 to 7.5 is actually pretty good. You may be able to go faster but two things will happen:
1) Errors will go up a lot as marginal processors come online
2) Heat use and power use will go way up as the higher clocks burn more power as do error producing cores
I ultimately ran my system with the CK firmware and get a good solid 7.3gh, < .5% errors, and a chip temp of 40c. What I'm going to do is put two more chips on my board, then try two more to see if I can get it to 23-24gh for an extra $100 or so.

is that really possible? I mean just put chips and they will work right away?
chips are not so high priced - and we already have all in place - if you could really do it it would be at least awesome )
