Overclocking Q6600 on Rampage Formula issue

[L.o.D.]

When I try to OC the quad to 333 or above, I don't get a video signal after I save the settings & the machine restarts.
Cpu voltage is at 1.5.
FSB is 333 or above.
300 works fine.
DRAM voltage is at 2.

Any ideas?
I used to be able to get it to run at 400 FSB for a 3.6GHz.

Lock the PCI-E bus to 100MHz and the PCI bus to 33.3MHz.

Right, thanks. I forgot about that.
Totally forgot that a lot of settings were reset when I replaced the Rampage for a new Rampage.

That's why you should always keep a text log of the things you change and the final settings you arrive at. ;)

It's be nice if I could do a printout from the bios. :)

Ok, the PCIe frequency was already set to 100 by default but canot find a PCI setting anywhere.

I still need help with this.

I can set my FSB to 333 & it will load fine but can't get higher.
