Help with 2x 7970 low kh/s cgminer 3.1.0

[scapeoflegends]

So I can only post here which sucks.. But anyways..

I am trying to get the most out of my cards.. But for some reason the max that I can get is only ~500 kh/s a card

My brothers miner is the same besides different cards and he is running at ~750kh/s a card

This is my cgminer settings..

Code:

cgminer.exe --scrypt -o http://ltc.nushor.net:8998 -u WaterSpice.1 -p x --intensity 13 -g 2 --thread-concurrency 8192 --lookup-gap 2 --gpu-engine 1044 --gpu-memclock 1500

I am willing to give a few ltc once I mine them..

See if putting the intensity to something lower or to what mine is set at which is 8, i know my 7970 dont work well with 13 for some reason :/

500 kh/s per one card or both?

500kh/s for 1 card..

Core clock/memory ratio seems to affect hash rates quite a bit. I'm getting 690 KHash/s with 1000MHz core and 1755MHz memory with a 7970 and the same settings.
