I am happy with 62

I read that going more than that starts to dramaticlly increase the wattage at the wall. currently it works out slightly less than 1watt per 1gh/s (about 0.95watt @ 800mV). i have a watt-o-meter and my PC and the 2 U3 are draining 162watts 24/7 from which 40watts is the PC then 60watts x 2 from the other PSU

I had a duff one form the same guy I bought these two. I was lucky to find them cheap on amazon because I know if something went bad returns would be a simple.. and my hunch was correct. The second one was running 45ghs and there was nothing I could do to increase it. Returned and the 3rd one runs like the 1st. No problem at all.

24hour mark now broken and niether the fixer upper nor the stock one ZOMBIED... Interesting.

Please upgrade the latest firmware if it still can start to work..RMA is accepted if it is still working on 45G at below codes:

Code:

cgminer.exe --bmsc-options 115200:0.54 -o stratum.antpool.com:3336 -u antminer_1 -o p2p.antpool.com:25 -u antminer_2 --bmsc-voltage 0830 --bmsc-freq 0982

cannot seem to find any firmware updates on the supportpages?

Its not on there yet (bumped for it to be uploaded), in the meantime I've mirrored it here because I already had a copy.

How do you update the firmware on these U3's?

no firmware update on these they are not running any linux embedded controller like the S1, S2, S3, S4 etc these are essentially a U1, U2 style USB device only with 4 chips in it instead of 1. Best bet is to use the latest version of cgminer this proved the most stable for me. Bitmain did release a new version a few days ago on his site but i run all mine on a raspberry pi so i haven't tested it myself
