leoftw, there are a number of ways to try for 3.6, could you be more specific? Here are the BIOS settings that I've found:

400x9 from Maglin
400x9 from giorgos th.

450x8 from Renegade5399
450x8 from cadaveca
450x8 from Grnfinger
450x8 from ChaosMinionX
450x8 from Zucker2k

All have reported varying degrees of success with their specific hardware. I haven't found one that works 100% for me yet.

edit: Ahh, and from the above I see that Grnfinger has tweaked his settings again. Exciting to hear that you're stable again Grnfinger.

Nuckin_Futs, has many pearls of wisdom strewn throughout this discussion. He had this to say about testing for stability:

As for the Quads in general, leave memory and graphics out of it till youget the CPU/mobo where you like and stable in 1:1. So for best stability, leave strap and RAM frequency to Auto, Disable both speed spectrum settings, Disable RAM Booster an drelax to 0 (1~3 as needed for stability, when stable again), Set Ai Clock Twister to Auto or light (for now, avoid "strong", as it will add stress to memory system and become unstable, destracting OC test), Enable Static Read Control. Getting higher FSB out of a quad is gonna need some more PLL and FSBT thgen in my core 2 OC. Matbe PLL up to 1.712v and FSTB to 1.504v is a good refference point.

Try this and use overvolting as little as needed for low temps and stability.

Following Nuckin_Futs' advice, I've been able to run OCCT testing CPU only with some of the above configurations, but not with the blend test, which tells me that my processor can handle the extra clock/voltage fine, but that I'm most likely overstressting/underfeeding my Northbridge. That's the theory I'm working with at the moment anyway. Later tonight I'm going to re-orient some of my components and see if I can't get some airflow over my Northbridge in order to get stablity.

Oh, and do note the thoughts offered by cadavega, on PLL voltage...very interesting:

I wanted to mention the importance of cpuPLL voltage. It is definately important to increase this votlage when going over 400mhz FSB with a quad. There is no specifics...each cpu will differ. For example, my B3 quad doesn't care for it...increase too much and stability was quickly lost. My G0, tho, was not stabe for 48hr prime without 1.8v...1.7v...33hrs...1.75v...38.5hrs...
Also of note is that my B3 did not need any FSB or PLL voltage change when FSB was increased(or it had negative effects), while my G0 ABSOLUTELY REQUIRED more vFSB and cpuPLL. b3 was happy with 1.2vFSB, 1.5v PLL, as a comparison.

Good Luck, and have fun.
