I think what he means by underclocking is setting the other components to run lower so you only hit one overclocking ceiling at a time.
Yep that's exactly what I mean. I'm talking about the part when you talk about overclocking the CPU.... During the first phase it is best to isolate memory, either by unlinking it, or putting it on a ratio... If you just start winding up HTT or FSB you are overlocking both at the same time.
The end result is to overclock both, but it is easier to get there by doing them one at a time to find the max of your CPU and max of your RAM separately so if you get failures you know which part is responsible.
I think in my feedback I was missing the final step where you take the results from overclocking CPU & RAM separately. Then at the end you figure out the good FSB + Ratio so you can have both at a reasonable, stable max (sacrificing a little RAM speed for CPU speed if you need to!).
You are right you don't really need to totally break out AMD and Intel but it would be good to point out the differences at each step. For example, from reading these forums it looks like most enthusiast Intel boards have a way of unlinking RAM, while that is not an option on AMD (that I have seen). If you mentioned at the start of the CPU section about unlinking RAM, or putting it on a ratio so it runs slower, and for AMD you have to turn the HTT down I think you would have it covered.
