Re: Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs
Maybe someone will find this useful:
I'm using 4x 7970 cards, all on x1 > x16 extenders.
Was getting max 690KH/s per card, but with old MB, CPU and only 2 of those card I was getting ~730Kh/s.
I've changed priority of cgminer.exe process in Task Manager from Normal to High, and voila ~730 again per card
So just make .bat with start "cgminer" \high in front and it will run it in high priority all the time.

That's weird, does cgminer.exe use any cpu processing power for the 7970's?
I don't think so, but I've noticed on old rig that, for example when I log via teamviewer, hashrate drops. So that was my hint for CPU related issue. Don't know if I'm the only one noticing this, but it would be nice if someone else could confirm/deny this.
what settings are you using for cgiminer?
and what gpu/mem frecv ?
Gygabyte 7970 OC model stock @ 1000mhz / 1375mhz mem
CoreClock 1040
Memclock 1500
cgminer 3.1.1 -I 13 -g2 -w 256 --thread-concurency 8192 --shaders 2048
