Solution for Slow Hash Performance for Litecoin Mining using Asus Matrix Platinum HD7970

Recently I bought two units of Asus Matrix Platinum HD7970 for Litecoin mining. Bitcoin mining using GPU is not profitable anymore but for Scrypt based coin like Litecoin it is still profitable.

I was excited when I got the card hearing most card like Sapphire Vaporx R9 280 and Asus HD7970 Direct CU II Top can get an average hash of 700KH/s

To my horror when I start to mining Litecoin using my newly purchased Asus Matrix Platinum HD7970 card I can only get 320Kh/s to a max of 500Kh/s using cgminer 3.7.2!!!

I am very sad. I try every setting including the one shown below:-

del *.bin
cgminer.exe --scrypt -o stratum+tcp://coinotron.com:3334 -u worker username -p password --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256 --auto-fan --gpu-engine 1080 --gpu-memclock 1500 --temp-overheat 80

After 3 nights of sleepless night I manage to find a solution :)
