What should be the total rate for two Radeon 7970?
Use the Linux system
Program: cgminer 2.10.5
That he wrote to me:
(5s) 783M (avg) 626 Mh / s
GPU 0: 69C 5073RPM 322.6M/314Mh/s A: 192
GPU 1: 46C 1070RPM (Huh) 322.2M/313.5Mh/s A: 223

Until the hour i use it, statistics on the pool says 572 Mh / s
Tell that to the normal speed for 2 video cards or something I did wrong?
Why in the second rotational speed is so small and the temperature is lower?
I would be grateful for answers.

Outside card is always cooler as it gets better access to the air. And that is way too low for your hash rate on mine I used to use this in my .cgminer/cgminer.conf.

Code:

"intensity" : "8,8",
"gpu-engine" : "0-1100,0-1100",
"gpu-memclock" : "950,950",
"gpu-threads" : "2",
"auto-fan" : true,
"auto-gpu" : true,
"temp-target" : "75",
"gpu-fan" : "0-100",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"donation" : "0",
"shares" : "0",
"api-listen" : true,
"api-network" : true,
"api-port" : "4028",
"kernel-path" : "/usr/local/bin"

I have modified it for your use give these settings a try it should just about double your hash rate. You may even want to raise the "temp-target" : "75" to 80 depending on how hot you want the card to get or if it starts to throttle at that temperature.

What would the cgminer .bat look like to get those same settings?

Better off using a cgminer.conf file to do it but if wanting to put it in a .bat then.

Code:
cgminer --intensity 8,8 --gpu-engine 0-1100,0-1100 --gpu-memclock 950,950 --auto-fan --auto-gpu --temp-target 75 ....

Basically put a -- in front of the option you want used on the command line in the .bat.
