I have two 6770's (one XFX, the other Sapphire) and each should get around 200MH. I'm only getting 187MH total.
This is on cgminer 2.11.4 on Xubuntu 12.04 64-bit.
cgminer -n

On Q (exit), I get:[2013-04-05 19:24:08] Summary of per device statistics:
[2013-04-05 19:24:08] GPU0 | (5s):0.000 (avg):94.06Mh/s | A:41 R:0 HW:0 U:1.2/m I: 9

Here's the command I run:
cgminer -o stratum+tcp://stratum.btcguild.com:3333 -u MYUSER -p 123 -o http://pool.50btc.com:8332 -u MYUSER -p 1 -I 9,9
I think maybe GPU 1 is not being used because its temp is only 27. What am I missing?
