I only bought 1 unit to experiment with and it has been running stable for over 24 hours on a Rpi.
My stats look like this.
Average 2.409gh/s
A 83568 R 156 HW 369 WU 33.5
I have adjusted the voltage to .9 volts and the clock is set at 300mhz (0B81).
BTC guild stats verify the hash rate.
Wish I had a more units

What does your command line look like?
I've been using:
C:\Users\M\Downloads\CTB\Antminerminer\cgminer.exe -o stratum+tcp://stratum.mining.eligius.st:3334 -u <"Shut up, Flanders."> -p --bmsc-options 115200:20 --bmsc-freq 0881
And seeing:

I'd like to get that average a bit higher, anyone have any thoughts? I think they are maxed for now. I do have a bunch of those weeny lil heatsinks, I'll put one on each of the ASICs, are there any other chips/items that would benefit from one stuck on there?
Also, since I don't want to fiddle with the miner jest yet, what do these commands do: "[P]ool management [ S ]ettings [D]isplay options [Q]uit"? I have a lil' bit of CMD.exe experience, but not a lot. I assume the miner window has to be primary, and I know what [Q] does, but what do the others do?
