3.6 IS doable on air for a revision G0, but hard to do with that motherboard. I have mine on a DQ6, and it does 3.6 OK and stable, but not F@H stable (a lot of EEU's). I had a B3 revision on a DS3, and it died after 2 months. Its now on an S3. Its VERY easy to get 8x400 BTW.
And its good to hear from you, been a while ! Last time I talked to you I was setting up my new dual 248's (that are now for sale)

Some processors (usually Intel) have the multiplier locked

There's an advantage to running at the stock 9X multiplier. You can still enable C1E and EIST so that your cpu won't be running full-bore when you don't need it. Intel indended Speedstep to extend the life of the processor by lowering the voltage and multiplier when the chip is idling. When you need the horsepower for gaming, video rendering (or showing off with benchmarks,) it ramps up quickly and effortlessly.
My Q6600 GO took a little coaxing and 1.42 volts (after vdroop, 1.47 in bios) to get to 3.6 ghz, 9x400. But it doesn't run at that speed all the time. With C1E and EIST enabled in the bios, it idles at 6x400=2.4ghz (the cpu's original rated speed) at just 1.31 volts, which is also the original rated Vcore.
I don't have to worry about temps, it idles in the high 30s and tops out in the mid 60s priming on all four cores.
You can't enable those cpu-saving settings reliably at a lower multiplier. At 8X you'll be running your full OC at all times, throwing out more heat and stressing the cpu even when you're doing low-intensity tasks like surfing and e-mail.
If it were me, I'd rather run 9x356 than 8x400. You get the same 3.2ghz overclock either way. If your memory isn't the greatest you can underclock it slightly at 2x356=712 mhz and maybe run tighter timings. If you have the good stuff, you might overclock the ram too with the divider at 1:1.20 (or 5/6) so the memory is running at DDR 854.
You'll get the speed you need when you need it, and when you don't the system will run cooler and longer with less strain on the cpu and mobo chipset.

Thanks N7 & BoboKatt. I know that the higher you push the FSB, the more stress you put on the NB. Accordingly, you have to add more voltage...which pushes up temps. And you go round and round until it explodes. :Q Er...until it BSODs. :laugh:
But, my MB has been running 400FSB at stock voltage for 14-15 months now. I know that no two CPUs are alike, but if the NB is "used to it", then isn't the ability for my MB to run 400FSB pretty much guaranteed?
I'd be very happy with 8x400 for the same 3.20GHz I have now, but with two more cores. I'm just curious how doable 3.20GHz is with the G0...and/or the B3 for that matter.

Thanks, Mark.
So, what's the word on steppings these days? Are the bigger etailers like Newegg all sold out of B3 and are shipping B0? I know ClubIT/Tankguys guarantee a B0 steppings but if I can just stick w/Newegg I'd be a bit more comfortable.
Then again, if B3 can hit 3.2GHz pretty easily, I'd be happy with that too.
Regardless of which stepping I get, I'm getting a Tuniq Tower to cool it.

Yes, I got my G0 from clubit, first time outside newegg in ages, and they came through, shipped on the weekend even ! Got it fedex in 2 days. And I have one B3 doing 3.2, the other is fighting me, but once I get my second DQ6, we will see ! I am dumping my P5K.
And did you read that my B3 killed my DS3 ? I don't know why, but it could have been that I didn;t heat sink the PWM's like Acanthus suggested.
Whats funny (and I don't understand) is that I have TWO quads on S3's and they have lasted longer than the DS3, why is that ?
