SpeedStep/C1E Problem?

[scottlpz]

So I decided to play around and bump my Intel E6700 up to 3 GHz by raising my FSB to 1200 MHz in the BIOS. However, CPU-Z is still showing my multiplier dipping down to x 6.0, giving me a clock speed of 1800 MHz. I have a feeling that it is SpeedStep or C1E causing this. These are the steps I have taken:

- Disabled Intel EIST in the BIOS
- Disabled D.O.T. Control in the BIOS
- Set System Clock Mode to "Manual" in the BIOS
- Disabled Spread Spectrum in the BIOS
- Changed Power Scheme to "Always On"

I don't have any options for enabling or disabling C1E in the BIOS as far as I can see. Is there anything else that could be causing this? System specs are as follows:

Intel Core 2 Duo E6700 Conroe running @ 3 GHz, stock voltage
MSI P6N Diamond (NVIDIA 680i SLI chipset, BIOS version 1.2)
OCZ Reaper HPC Dual Channel DDR2 running 4-3-3-15 @ 800MHz, 2.1 V
eVGA GeForce 8800 GTS 640MB (running stock speeds)

Thanks for the help.

E.I.S.T.= Speed Step, and it's what's responsible for changing the multiplier down to 6x. C1E is the other half of the equation, but it's only responsible for dropping the vcore down to 1.1v, after the multiplier is lowered. I guess that MSI just has them enabled/disabled with one setting, instead of two; they're weird like that. BTW, what's to complain about? You're able to successfully overclock, but you still get to run your processor slower and use less electricity while you're browsing the web and/or listening to music? I wouldn't be complaining.😉

Do you have the MSI dual core utility installed? I made the mistake of installing that yesterday, and it started screwing with my FSB to meet its pre-set ideas for what it should run under certain conditions. I did a 3DMark run and it said I was running at 1900MHz, and I had a giant ?. Removing the MSI utility got things back up to speed.
