So for the record, I wasnted to be more specific. I'm currently running my Q6600 G0 at 400x8 with 4x1GB of Crucial Ballistic PC2-6400 with a 1:1 ratio and 4-4-4-12 timings.

When I was having the PCIe x1 problem, I was running the following settings:
PCIe clock - auto

voltages:
PCIe - normal
MCH - normal
RAM - +0.2V
CPU - 1.325V

To solve the PCIe x1 issue I adjusted my settings as follows:
PCIe clock - 110MHz

voltages:
PCIe - +0.05V
MCH - +0.05V
RAM - +0.2V
CPU - 1.325V

I'm not sure why the others needed so much extra MCH voltage, mine seems to be perfectly stable with these settings (they must be pushing 500MHz+ FSB speeds or something).
So, I posted this a few weeks ago, but I've recently upgraded my cooling in order to reach 3.6GHz. Now my machine is stable when I simply increase the multiplier to x9 to reach 3.6...but I'd like to switch to a faster FSB and drop the multiplier (450x8)...the problem is the PCIex1 issue again. Anytime I get the FSB that high, I cannot seem to get my PCIe to stay at x16. I've tried incresing my PCIe, FSB, and MCH voltages all to max, and I set my PCIe speed to 105MHz manually, and that got my PCIe up to x2...but no matter what I do, I cannot seem to get PCIex16 with 450MHz FSB. Is there any difinitive answer to this PCIe speed issue???
