AMD Phenonm II X2 550 BE drops to 803.6Mhz


Recommended Posts

Interesting performance numbers from CPU-Z and Core Temp. When I first boot my system and or the monitor 550

CPU Frequency starts out at the rated numbers little over 3,100Mhz and 200.91X15. Within few seconds it drops to 803.6MHz 200.91X4. It also floats around up and down, but never back to the high.

 

Is this normal? Is the BIOs lowering it because of some automatic setting? Plan on getting a better MO so may not be an issue but what causes this kind of data. In the land of the blind the one eyed man is king.

 

AMD Phenonm II X2 550 BE packaged with Gigabyte M68M-S2 Mother board

Corsair XMS2 DDR2 800.

Radeon HD 4670

Hitachi Deskstar 640 3MB

Windows 7 64bit Professional

 

My current MO is a dog and is most likely set at defaults as very little is adjustable.

I believe that is AMD's Cool'n Quiet software.

 

It throttles down your CPU speed when you're not fully utilizing it (I think it might shut off 1 core too) to save energy and make it not as hot.

 

Things throttle up again when needed.

Disable Cool'n'Quiet and C1E in BIOS and this wont happen.
