So, my 2.4C has been sitting at 3 GHz for about 5 months now, with no problems. My Corsair PC3200 is at DDR400 at 5:4.
Two days ago I changed my AGP aperture from 64MB to 256MB. I beleive this is the only BIOS or other configuration change I have made to the system, except for switching antialiasing and anisotropic filtering on and off constantly - but I always do that.
Today I realized that my 2.4C was running at 1500 MHz. I used CPU-Z to confirm; my FSB was at 125 MHz, and my memory was at 100 MHz, despite the fact that the FSB was set at 250 in th BIOS, and the memory ratio was at 5:4. Restoring the BIOS defaults did not fix the problem - as soon as I changed the FSB back to 250, the system would boot at 1.5 GHz.
Clearing the CMOS and putting everything back to where it used to be fixed the problem, and now I am running at 3 GHz again. If I change the AGP aperture back to 256MB, the FSB drops again. What's going on?
