My iMac is (ahem) irregularly clocked.

Decided to open up CPU-Z one day, and realized that one of my iMac's (2007 refresh, 2.4 GHz) cores was clocking far lower than 2.4 GHz. It seems it only has a 6x speed multiplier, while the other one has a 12x multiplier.

Is this normal? I'm such a noob

(this is RMClock, not CPU-Z.)

I don't think it's right anyway. Don't iMacs have Merom processors?

 

[TheG3Guy]

it still says the maximal for both processors in 12x, so id guess that the other processor isnt being used and is power down to save power

Actually, I think Merom is the mobile version of Conroe.

Hmm, I can only hope
I'm not sure if Vista has that capability, though, but it's strange in any way.

Whoops, accidentally doubleposted.

That's Speedstep in action. It's supported in Windows XP and Vista. When idle or under low load your processor will drop to the 6x multiplier.

It's built into the processor, it'll under-clock when idle/light use.

Speedstep. The iMac is a laptop with a big harddrive and big LCD.

Ah, thanks!
