Phenom II X2 560 clock downgrade on AM2 GA-M56S-S3

Hi,
I have GA-M56S-S3 rev1.0
bios: f6h
I've upgraded cpu from Athlon X2 x64 5600+ to Phenom II x2 560 BE (HDZ560WFGMBOX)

The motherboard supports the CPU:

http://www.gigabyte.com/support-downloads/cpu-support-popup.aspx?pid=2607

After upgrade I manualy set multiplier to 16.5 in bios.

Windows 7 64bit reports cpu clock at 3,31GHz but in fact the cpu works at multiplier x4 at 803 MHz (this is shown in CPU-Z)
Applications and games woks noticeable slower.

I tried to chance cool&quiet option in bios, also removed every nForce560 driver from Windows, but it still wokrs at 803 MHz

What should be done to get it working at full speed 3,3GHz?
Please please help
