numbers are pretty good for 3 sticks at freq 331 should about 51gh and is around 48gh for overnight I am fine with this
So 3 compacs OC'd equals roughly a U3, that's pretty cool. Much less power use, much less hardware problems, and made by a member of our community, not some Chinese mining conglomerate. Can't wait for my 4 to arrive!
Depends on how much you overclock it. Probably around 350 is a practical max for long term, I had four sticks running at 400MHz over a weekend and they had only two hardware errors and averaged 87.90GH/s, where expected is 88GH/s. Sometimes though, some of them didn't seem to want to properly start up at such a high frequency. They never had any trouble starting at 350 or so, however.
Also you're probably not going to run very many sticks at 400MHz unless you have a really beefy hub or one with a whole bunch of extra ports not in use.
It appears to me that hot-plugging is actually "better", which I found surprising.
I've seen odd behavior of cgminer on windows not actually starting to mine at first unless you hotplug as well. Usually it only does it the first time I plug a stick into my machine. It seems to be something with the zadig drivers, I'll see if I can figure out why it does that but it's lower priority than some of the other driver improvements.
As far as detecting as an AMU- it gets pretty nasty to differentiate the compac from the U1/2/3 because from a software standpoint the only difference is the extra identifiers we added to our sticks. If it checks to see if they look like an AMU, they appear identical because bitmain added no such info. You might ask Luke-Jr if maybe you used a slightly wrong COM identifier or something else that made it come up that way.
