So I recently built a system with the AMD 1090T cpu.
In Windows 7 64 bit, I run cpu-z and note that my core speed is about 800Mhz at idle - which I guess is some power-saving feature at work. When I stress the cpu, with prime95, the speed shoots up to 3200Mhz. So far so good.
Now, I have also installed XP Home 32 bit and when I look at cpu-z it show a core speed of 3200Mhz at idle! And that speed (obviously) doesn't change if I run prime 95.
So what's going on here?
Does XP not have the power-saving goodness of 7?
Or could cpu-z be reporting incorrectly?
Gah! I can't edit my message
So here's some more info...
My coretemp is 24 C at idle in XP. Prime95 sends it up to 50+.
So I reckon cpu-z is showing a wrong speed because surely 3200Mhz would not be at 24 C with a stock fan.
