Gigabyte GA-P35-DS3L, Q6600 mobo - running 3 virtual machines... O/C to what?

[Deja Q]

I have 8GB in my system (four 2GB Corsair modules:

* Cas Latency: 4
* Timing: 4-4-4-12
* Voltage: 2.1V
* Heat Spreader: Yes
* Model #: TWIN2X4096-6400C4DHX
* Item #: N82E16820145194
* Return Policy: Memory (Modules, USB) Return Policy
)


333x9 (RAM at 667MHz)

Or 400x8? (RAM at 800MHZ)

I know the northbridge on the mobo will have to be ramped up.

At 3.2GHZ, can the CPU live with air cooling? (Zalman 9700 fan)

[Deja Q]

1. Am testing right now, 400x8 with current stats:

DDR2 at 2.1v (+.3, but now running at stats rated BY Corsair -- I had been using 1.8v at 667MHz) -- 4-4-4-12 timings, 1:1 ratio
(G)MCH overvoltage +.1
FSB overvoltage +0.1
CPU is at 1.331v (BIOS, PC Wizard reports 1.326)

Windows Vista claims the CPU is running at 3.6GHz, however the BIOS and PC Wizard show 3.2GHz.

Temps:
Core 1 - 56 degrees under load, 40 idle
Core 2 - 51 under load, 38 idle
Core 3 - 49 under load, 37 idle
Core 4 - 51 under load, 38 idle


Load: Running Prime95 (64-bit version) AND SuperPi (32-bit) simultaneously -- Task manager currently reports 6.2GB of 8GB RAM in use.



Why would Core1 be running higher?

2. Isn't core 1 the natural default?

If the programs aren't set up for multi-core, I think they default to core 1.

3. Not necessarily...

With SMP enabled, Windows will put any given system applet on any given processor.

Multithreaded, SMP-aware apps will recognize multiple cores and distribute tasks amongst them.

Most software won't make use of 4 cores, but I've managed to hog-tie my system on some occasions (3D rendering, virus scan, 3D game playing)

4. Don't have much to add but...

...our systems look very similar:
