This happened to me recently too.  I was getting 390 m/hash consistently with 930 clock and -v -w128 -f60 (wanted to keep it cool at around 63 C.)  Then, about 3 days ago, I noticed it's only getting around 330 m/hash.  Not sure what's up.

Do you have auto-update turned on? Maybe MS pushed something bad.

The Windows version of the ATI drivers don't always recognize the need for full speed clocks. Next time it happens, run something like GPU-Z and see if the graphics card is being slowed down.

Thx, there was probably some other process. After 2 system reboots it did help.

Hi,

I was using my radeon hd 6950 for quite some time with avarage 320mh/s but today it suddenly dropped to 180mh/s.

Could someone explain to me why did it happen and how can I reverse it?
