This thread inspired me, so after getting my 5gh/s jally last Tuesday I ran it (5.1gh/s, 34 C), and ordered a Dragon.

Dragon came on Tuesday, flashed the unit with the stock 1.25 firmware (speed 7) and performance went to 7.3gh/s. Nice. Temp went to 40c, I noticed one chip was putting out 3% error rate, other was at zero %.

This evening I flashed it with diagnostics set to one (to try to get more cores), speed to 8. Performance is around 7.7gh/s, Temp is 45C, one chip is putting out close to 9% error rate.

Looks like one of my chips is a tad bit substandard. Not sure if going to 9 will speed me up more or overwhelm the slower chip, but in either case the heat increase is substantial.

I've ordered some artic heat sink pads to replace the wimpy ones on the unit now, but for a $169 or whatever I paid for this when I ordered it in Jan it's not too bad. I might back the speed back down to 7 since the higher error rate might not be worth it, or should I go to 9?

Thank you everyone for the help.
