Switched from cgminer3.9 to 3.10 and managed to overclock to 52:2:950 with much less hardware errors and no asic timeouts. Now it averages at 21.5gh/s. Temp is about 36°C.
At 53:2:950 the hardware errors are way over 20%...

40:1:850   19.5Gh/s   1.5%   30°C
50:2:950   19.5Gh/s   1.5%   34°C
52:2:950   asic timeout
i also tried your best result
54:2:850   20.0Gh/s   4%   30°C

it would seem that my miner is hardwired to work best at 19.5Gh/s

This means the boards for Europe are already on route?
(Also, i can swap the parts for my board just confirm that the U20 is TPS62142, and i you followed the datasheet that inductor would be about 2.2uH-3.3uH )

I assume barntechs inbox i full so I'll post my question here. Maybe someone will have an answer...
What is the difference in days between express and regular shipping? Trying to compute if it's worth it. Thanks.

I have the same problem. Running Bitcoin-Qt 0.8.4 on Win7 64bit.

I think i get it. If someone asks me to sign a message instead of just sending a message like [message] i should add something like [Form the desk of chriscross (and other identifiable details)]? Right?
The second warning i still don't get...

Hello
In the sign/verify messages window of the official bitcoin wallet there are some sentences that i do not quite understand.
"Be careful not to sign anything vague, as phishing attacks may try to trick you into signing your identity over to them."
"Be careful not to read more into the signature than what is in the signed message itself, to avoid being tricked by a man-in-the-middle attack."
I don't get these warnings. Could anyone clarify?
Thanks
