help getting vcore stable, q6600, ds3l, 3.2Ghz 9x356

Hi All, I just signed up here, I'm a regular on Anandtech and find myself lurking here all the time and finally brought myself to sign up. Hoping to get some different viewpoints.

Anyways...

Here's my Dilemna This is my first major overclock, the last overclock I did was with a P4 northwood 2.6Ghz back on socket 478 up to 3.0Ghz and that was no problem because it worked for me on stock voltages and I barely had to change anything other than the FSB.

currently I'm trying to Overclock a Q6600 G0 from 2.4Ghz to 3.2Ghz on my GA-P35-DS3L board, and I can't seem to find that magic voltage that makes everything right with the world.

my Motherboard VID is 1.2875, in BIOS i've set it up to 1.318*

My Ram is 2 GB of OCZ GOLD XTC PC2 6400 DDR2 Matched pair dual channel kit, running in dual channel mode 5-5-5-15 however it will run 4-5-5-12 easy, but for the sake of stability I have SPD to auto

at auto voltage CPUZ reports 1.344 and I believe goes down to 1.312 under prime load temps never seem to exceed 60C

with 1.318* in the BIOS CPUZ reads 1.264 at idle and 1.216 at load, again temps not exceeding 60C loaded

(it should be noted that the DS3L doesn't have an option to leave individual voltages at auto, just in general, either all voltages are auto, or they are set to normal or manually.

I'm over 12 hours prime stable on auto, however I'm told it's not good to leave the voltages at auto, but I'm also being told that my particular board won't allow itself to exceed 1.35V and it's fine to leave it on Auto as well as C1E and EIST on.

really I'm just looking for a Stable safe OC, my upgrade cycle is a bit longer than most, usually about 4-5 years so it's absolutely crucial this is stable, I'm even willing to clock down to 3.0 if it means it's that much safer. any advice is appreciated

EIST and C1E are off.

Well I could see the CPU getting replaced possibly as early as 2 years down the line once the penryn mainstreams have been out for a while and get eclipsed by nehalem, I could see the same thing happening that happened to the e2000 core 2's where they got dirt cheap once the e4 e6 and now even e8's are out, when I talk about 4-5 years I mean a complete rebuild, this computer was a complete rebuild from a P4, socket 478 system that I'd built in 03-04ish that I sold just last week and stil runs like a champ just lacking in the cojones dept.
