Hi:

I am having a dual HD6990 set up in windows 7. I am using msi afterburner to downclock the memory clock for my cards however the memory won't go below about 780mhz.
say, If I set it to 625mhz it goes all the way back to 1250mhz...
Also, the min value on the adjust bar is 620mhz  so how can I even down clock the memory clock to around 300mhz???

So, Let me know what I did wrong...
Thanks in advance.
