^Yeah, in most cases, the 'x.x ghz' moniker isn't all it's cracked up to be. I've had my Q6600 G0 at 4.0ghz before, but it's not stable at CPU load over 75%. I typically keep it between 3.2 and 3.4ghz and it's rock solid and I've never had any issues with any application or game...ever. Yeah, you'll score better in benchmarks, but in real world applications, where does this benefit you? When you are getting 80+FPS in a game...is 85FPS going to make a difference? Not likely.
Yes, its always fun to push the limits and its good to learn how a system works, so I am not knocking your efforts...at all. If anything, I applaud them. I just don't think that everyone realizes that because they have read 'so and so's post about their clocks on a similar system' doesnt't mean you also automatically can achieve the same results on yours. Each hardware component is different, almost like people are different, in specific capabilities, environment, usage and lifespan. Yes, you can expect 'similar' results; no you can't necessarily guarantee them every time on every similar component or build.
