Intel P4D 830 Overclocking question

[Wizzard005]

Hello Everyone,

I am not new to overclocking, however I have a question about one of my new setups. I just got a Intel P4D 3.0Ghz (830)

Anyways, to make a long story short, I have it overclocked, however Windows and the bios says its running at 3.4Ghz , but CPUZ says its running at 3.2 or so?

What do i belive , windows or CPUZ?

I tried to OC it to 3.8 or more, but the PC just crashes and when i have it running that high the computer thinks its like a 4Ghz+ .....

Also, in the bios , there is no option to mess with the FSB, well there is a FSB, however it starts at 800Mhz instead of the 200?

I have the ASUS P5ND2 SLI Motherboard.....

If I cant overclock it, I may just got trade it in for a P4 3.4/ 3.2 or something..

Let me know what you think.

Try disabling EIST (SpeedStep) in the BIOS. It could be turning your multiplier down from 15 to 14 (the minimum for Pentium D's) when idle.

True and in the ASUS BIOS the FSB is quad pumped, so instead of seeing 200 you see 800, and when you OC for lets say 220 fsb you need to put 880 . Also, what BIOS version are you using?

windows takes it cpu rating right as windows starts up and from the looks of it so does AIBooster. Odds are speedstep is coming into play and lowering the multi, as was suggested above. Id try playing a game and alt-tabbing to check. Use CPU-z its by far the most accurate in my experiance. (Both my bios and windows tell me my cpu is at 266mhz right now, its running at 2500mhz, cpu-z reads just fine)
