Why is faster slower?

Recommended Posts

I ran the A:M three teapots benchmark on my Core 2 Quad Q6600 machine.

At the stock speed of 2.4GHz it takes about 5:10 per frame

I have a utility to overclock the CPU.

At 2.8GHz it takes about 4:14 per frame, which is about 20% improvement for only a 16% increase in speed.

But at 3.0GHz the time goes up to 4:40 per frame.

So what goes wrong at that higher speed?

How hot is your CPU/GPU/Mainboard?

It might be that at a higher clock speed some other component on your computer is getting hotter and that might be bad for it.
(only guessing here of cause)

You could test it by opening your case and trying it again.

The case was already open but I tried it again and got better results.

This time at 3.0Ghz i got 3:55 per frame. I don't know why it is different.

The CPU temp peaked out at 42° C which doesn't seem too bad.

42 °C is totally fine even pretty good.
Are there other sensors on your board like Motherboard, DIMM, etc?
But it is not that common to be a problem if your CPU is that nice.

There was also a "System" temp displayed but that was always within a degree or two of the CPU temp.
