Old veteran Rad 7950 miner here trying to get more out of this old ASUS 7970 3GD5, seen here:

cgminer 3.7.2 with -I 13 (above 13 gives HW errors, but we all know that by now.
-g 1 (2 just slows it down) -w 256 --thread-concurrency 8192 (higher doesn't seem to yield any better perf.) --gpu-powertune 20 --lookup-gap 2
Core 1050, mem 1375 or 1500, I have tried core from 800 up to 1075 and mem from 1300 up to 1600-1700, 1375 and 1500 seems to work best for now.
I'm only getting 560 KH/s, any advice on how to make it up to 600, 650, 700+? Flash the BIOS, etc?
