Yeah, but I mean I was not able to use a 150 for my 6990 card, only 125.
150 memdiff works on 7970 though.

A 6790 won't be much more than a 5770. To maximize your speed, tho, make sure you are NOT using an APP SDK 2.6 or newer. APP SDK 2.5 is your best bet.
Try these settings:
Just curious, is a 6790 able to do a --gpu-memdiff of 150 without reverting to default mem clocks? Do not know about the whole 6xxx series but my 6990 is only able to do 125. Try these settings:
Code:
--temp-target 70 --auto-gpu --auto-fan --gpu-fan 25-80 --gpu-engine 900 --gpu-memdiff -150 -I 8
I had to flash the bios to go lower.

Alright dropped the later SDK and installed the 2.5 version. Went into the cgminer's bitstreams folder and moved all .bin files into a old bin folder. Just a buncha .bit files left. Running command line with your recommended options and we're pushing 202Mh/s. You're the man.
I'm tweaking my HD6870 now.
Thanks bro!

1016.4 is the opencl runtime that comes included with 12.10. You need to downgrade to an older opencl runtime, and direct CGMiner to use the older version. Re run the 12.10 CCC driver installation, and completely uninstall the openCL runtime (you can leave the driver and everything else alone). Then install the APP SDK 2.5 from HERE. Delete the .bin files out of your CGMiner folder, and see what that does for your performance.
If that doesnt work, I have an 8MB rar file with the 64bit opencl runtime files that you drag and drop into your windows folder. The installers don't like it much, but it works.

Yeah I'm getting about 179MH/s using
--temp-target 70 --auto-gpu --auto-fan --gpu-fan 25-80 --gpu-engine 1050 --gpu-memdiff -150 -I 8
--temp-target 70 --auto-gpu --auto-fan --gpu-fan 25-80 --gpu-engine 1050 --gpu-memdiff -150 -I 8
What driver/SDK are you using?

What are the best settings to maximize the Mh/s on HIS Radeon HD 6790 running cgminer 2.10.0. Right now it is about 66 degrees Celsius. I'm letting it auto-tune.

The CGMiner defaults should be best for worksize, vectors, and kernel. The only thing you should change is your overclock. You want your core clock as high as you can, while your memory as low as you can. Try these settings:
Code:
--temp-target 70 --auto-gpu --auto-fan --gpu-fan 25-80 --gpu-engine 900 --gpu-memdiff -150 -I 8
