Alright, added 3 Scythe fans to my case.
I replaced my Noctua on my TRUE with a 1900 RPM Scythe.
Core Temps down to:
32/32/27/27
Very nice sir!

Yeah I agree that its the luck of the draw sometimes.
I'm hitting a wall at 3.5Ghz methinks.
Running 390 x 9 = 3510Mhz and idling at 45/42/35/34 at 1.43v (in cpu-z). Load bumps that up to 60ish across all.
Some people hit 400 x 9 really easy and some others... don't.
Sounds like you might get 3.4ghz. When you ran Prime95 did you run four instances to make sure all 4 cores were stressed? Check windows performance tab under task manager to make sure they are all being worked. My coworker made the mistake of only working 2 and his temps were great under load that way lol. This will also help you see which cores are failing first. Did you try 8x400 to see if your FSB limited on your chip? Also make sure your memory devider is putting you back into spec. I try to run my memory as close to 800mhz as possible initially to rule out any memory issues during my OC. When you get your cpu OC right you can go back and start pushing your memory higher. Congrats on the rig. It sounds like a nice setup!
Yeah I agree that its the luck of the draw sometimes. Once I establish my highest stable OC, I"ll then play with my memory timings. Question is, if 355x9 is the highest it can go, should I run a divider for more ram bandwidth? I hate the idea of UNDERCLOCKING anything, it's like paying for something that you don't use at all! lol. Thanks for the props,
Btw, if you're curious, here's my Crysis benchmark so far (@1280x1024, everything at Very High). Avg fps ~31 !! Crazy!

Idling in the 40's is a bit high isn't it? But that's a great OC, I'll do more testing today and see what happens.
I hit 9x400 with my q6600 but it takes a hair over 1.5V to get stability. I can run 8x425 @ 1.38V so I just leave it there. My peak load temp on my hottest core was 62C after 10 hours of OCCT. I expect a little temp drop when the arctic silver finally cures.
Yeah I wouldn't go over 1.5, although with Vdroop it should still be under 1.5. What were your other voltages btw? NB/FSB? I think that's my limiting factor right now, they're still on auto.
I was able to run my Q6600 at 377 X 9 for 3.4 stable at 1.5 volts but my temps were in the high 60's. I run day to day at 3.2 and 1.4 volts with temps in the low 50s under load. Anything above that would cause errors in Prime 95 within a few minutes.
I tried running my P5K at 400 X 8 , and it appeared to be stable in Prime 95, but after 12 hours or so, the system would just blink off like I flipped a light switch and reboot. After several times of that, I went back to 355 X 9 for daily use.
I'm happy.

3.2 is pretty stable for many people it seems eh? I'm also there (355x9), but maybe I"ll go 400x8 so I can use my ram 1:1 and see if it's stable, without random reboots! Otherwise eitehr a) I under clock my ram in sync mode, or b) OC it using whatever divider (maybe run at 866) and tighten up my timings.
Can you guys please post ALL your voltages (fsb/vcore/nb/sb) please? Thanks a lot!

Copy: Sounds like your system @3.4 is rock solid, good to hear. I'll keep playing with mine. Given that I'm around 55C (max) @3.2, hopefully I can go to 3.4 without the need of getting into lapping. That's a bit beyond me to do (time constraints as well).
Thats great that you're under 60 as well, looks like you built it well. I'm using the true with a Scythe sflex (1600rpm), it's pretty quiet as well, not whisper, but better tahn my old p4 so I'm happy with that.
I'll check out photobucket tonight and upload my pics. I think c1e is disabled as well, but I forget right now (I just followed the guide on tomshardware for what to disable/enable, the manual doesn't explain these things very well).
Let's see if lady luck is on my side tonight.
Update: I was able to get into windows with 450x8, but I only saw two cores!! Did I reach my motherboard limit? Just for testing sake I used vcore of 1.5 and nb volt of 1.55. I might have to try lower, again shooting for the stars here

You try 8x425? The two core thing is weird. Here is a snap shot of mine at idle with an ambient of 76F in the house. I enabled C1E and it helped a bit.
more likely cpu limit. i get that when overclock is unstable.
Meh, for prime95 stable @3.6, i need at least 1.47v bios voltage for my q6600. Even then, temps are still high for me... 66-71c. I have a TRUE and scythe s-flex 1600 fan, and both my q6600 and true are lapped, using as5. >.> Horrible temps, and its not even that hot right now in my room.
But at 3.2, i never get passed 52c.
Pretty dissappointing, but it works...
ps, do you guys also up your nb voltage/fsb volts/ or pci-e volts?
Well bios isn't accurate because the vcore is never totally constant (Vdroop etc).I simply meant what voltage is actually going to the CPU? Is it the bios voltage or the voltage displayed in windows (by cpu-z). Just wanted clarification (with reference to my previous post), that's all.
I posted both vcores in my earlier post.
No I don't run any OC for daily use, since I don't see much performance increase. I don't need that much speed.From your specs, you don't OC for daily use at all? how did you hit 9x400? Vcore of 1.36 (bios) and any other voltage changes?
