What a Crap
I´ve the same Board, running C2D e8400, Stepping e0 @4200 MHz.
First: start in your BIOS, and @ the Main Page press "STRG+F1" simiultaniously.
So you switched to the extended BIOS.
Problem: the Board can't switch to more than 342 MHz FSB without setting the PCI-E Speed to more than 100 MHz.
Some People told, if you switch PCI-E to more than 110 MHz, the HDDs (SATA and IDE) will fail.
Never seen that, my PCI-E is @ 145 MHz and FSB is switched to 467 MHz.
With the C2D e8400 i'm with that setting @ 4200 MHz.
CPU runs @ Stock Voltage (+0,005V), RAM (DDR2) runs @ 934 MHz.
My English is not the best, but if you wanna know more about the Board and CPU (QX9650), just post here and you'll get an Answer from me.
I can help you defintely to get the most out of your CPU, i promise.

Here's the Sys i made with the Gigabyte GA-G31M-S2L @ e8400 (sry, it's in German):
Just if you're interested anymore, post here, and i'll help you

Just lil more Info:
I use just the Stock Cooler (good one with copper core), delivered with my e8400.
You have to look:
the CPU-Case is running out of Temp @70 Degrees Celsius (told ya: i'm German) it's about 158 Degrees in Fahrenheit.
The Core of the QX9650 are out @ 100 Degrees Celsius (=212 Degree Fahrenheit)
Normal Worktemperature is at least 149 Degree for the Case and 185 Degrees for the Cores.
At this temperature the CPU will slow down (Throttle), at 203-210 (the Cores) Degrees the PC switch off.
QX9650 is a little "HOT" (130W TDP), so, perhaps look for a better cooler.
But with Stock Cooler arriving 3,33 GHz will be, in normal circumstances, no prob.
If you see in the PIC above, i switched the RAM (@934 DDR2) from Latencies of original 6-6-6-18 to 5-5-5-15.
Not every RAM works with this, i've Middle Class "Hynix" RAMs, they work with it...
Just test it, once more: i'll help you if you want.
Against of all the People say here: the GA-G31M-S2L is a nice Board for OC, just the Northbridge (FSB) sucks out over 470-480 -MHz (No matter if you give +0,1 or 0,2 V more).
You can buy it for about 25-35€, so I love it for that Price !!!
Hehe, while i wrote this Post, my other Computer (Asus P5B-Premium (Intel P965 Chipset) @ Intel C2Quad Q6600 2400@3000 MHz) restarted with no need...
THAT'S OVERCLOCKING !!!
