Why does clock ratio drop on idle E6300 & DS3

[EddScott]

I noticed today that although the bios on my DS3 board showed I should be getting over 3ghz and I thought everything was fine, once getting to windows it seemed to be running slowly than stock.

I cleared CMOS and started again. Now running like this :-

430 X 7 @ 1.375
2gb Geil Value 55515 @820 (system multi 2.00)
Tweaked the volts on the memory by 2.

Anyway, running CPUz shows the ratio as 6 but then jumps to 7 under any load.

Why is this happening? I've never noticed it before. I thought the puter had been running 3+ for at least 6 weeks.

CPU Z is weird, shows multipler errors for me two, shows it as 6.0 sometiem even though speed spet is disabled.

C2d auto throttling, its normal. You can disable it in the BIOS, I forget the name of the setting.

Intel speedstep when enabled will automatically drop multiplier to 6 when cpu is idle,and will restore bios clocks as soon as cpu activity is detected,cpu-z is reading correctly,you can disable the feature on most boards in the bios.
