D975XBX2 E6700 overclock advice

Hello,

Curious if anyone can point me in the right direction to overclok the obve board/cpu.

I had an Asus p5n32 SLI SE, and ran okidoki at 3.0ghz. Thus far just upping the MHz to get to 3.0 and I can't post.

No, I don't know what I'm doing

I have 2g OCZ DDR2800 Ram: ocz2g8002gk

You may want to go in to POST bios and disable failsafe watchdog. (If new OC doesnâ€™t boot you will have to move the jumper to post again to clear settings) My limited experience and things Iâ€™ve read on this site have shown that watchdog messes with OCing. Reboot and go back in to bios and set ram to 200/533 then push fsb up to 300. Should give you memory speed of 800mhz, and CPU @3ghz.

This link helped me out a lot.

The link I have...I don't fully understand it yet.

A little confusing for me on the FSB...as I don't actually see a place to set FSB
I did try the settings you gave (FSB to 300 is actually CPU mhz speed to 300?).

Anyway, thats what I've done and I'm at 3.0ghz..windows running prime ok so-far.

Glad to hear it worked. I should have booted in to bios to verify the wording you would see, but it appears you figured it out. My bad.
Link shows how settings on FSB relate to memory speed. Multiplier is 10 for E6700, so use drop down to input 10. Now look at Ref Freq MHz & Mem Freq MHz and to DDR2 Equiv MHz to see the memory speed. I am using PC6400 (800mhz) and didn't want to OC it so my goal for memory speed was 800 and with 200/533 this is what I achieved.
