3) As stated above, always take what you read about max OC with a grain of salt, mine never hit what everyone else says.
RAM depends on how high FSB you expect to run. Personally I just go with cheap RAM because the extra $50-100 for expensive RAM can be a couple speed grade bumps on a CPU. Basically, low ROI IMO. However, if you're planning for really high FSB, then you pretty much have to get fast RAM. Basically know your FSB goals before buying.
As for #3, it really is YMMV. The thing is that people are more likely to shout out their successes than their failures, so what you read on forums are biased more towards successful overclocks. Also, people have varying personal definitions of a "stable" overclock. Some feel that their overclock should be 100% stable under indefinate stress testing. That's the ultimate in stability, but of course renders your system indefinately useless if all you're doing with it is running stress tests. :laugh: Some feel that their overclock is "successful" if it can boot up Windows, grab a CPU-Z screenshot and run a few seconds worth of SuperPI.
I've had chips that were really good, and chips that stunk at overclocking. I had one Opteron 144 that was so bad that when I posted about it here, people started calling me names.

isgust; It was one out of three chips. All tested on same parts. One chip was good for around 2.9GHz, another one a bit less. Third chip would barely hit 2.3GHz. All on same parts (mobo/RAM/HSF/PSU).
People who refuse to understand that some chips overclock higher than others are just... <I'll be nice and not say anything that may be construed as a personal attack>
It peeves me to see people write stuff like "oh such and such chip is GUARANTEED to overclock to ?.?GHz" Oh rly? Who's gonna guarantee it? You gonna put your money where your keyboard is and offer to buy chips from people that can't reach your guaranteed overclock?
That's just setting people up for disappointment.
BITD I sold "pretested" Celeron 366 CPUs "guaranteed" at 550MHz. If it didn't work as specified, refund. Now THAT is a guarantee! I can say this... we got in many, many trays of OEM chips. about 2/3 of them were easy 550MHz chips (we binned for those requiring Vcore and those that did 550MHz with no additional Vcore). The rest
just couldn't do it in a stable and reliable manner. Why I mention this was that at the time many in forums were proclaiming these to be "guaranteed overclocks." My clientele were either those who didn't want the risk, or had taken the risk and ended up with a chip that wouldn't hit the higher speeds.
