I'm glad it was helpful. To be honest I really didn't even read it. I just googled a guide and skimmed over it making sure it was at least slightly relevant. There are two guides on this forum, one is complete crap and the other is pretty good but could be organized slightly better.
There really isn't that much to it though, if you get stuck and want to figure out what is causing problems try to test each part individually. For example if you suspect the memory speed is holding you back, back off the CPU/Northbridge multiplier while retaining the memory speeds and see if you still get crashes.
My biggest word of advice is to not use "Auto" voltage settings. Many motherboards will ramp up voltages to dangerous levels when left on Auto and the HT bus is increased. Spend an extra 2 minutes to set all the voltages to what the BIOS says is default manually and it will allow you to pick out problems easier.
Another thing that has helped me is to find a way to reset the BIOS easily. Removing the CMOS battery for 10 minutes definitely works, but it is time consuming. For my motherboard, if I start it and then shut it off really fast before it posts it will automatically clear the CMOS. If this doesn't work for you should see a jumper near the CMOS battery. Switching positions, booting, and then switching again will reset to factory defaults. Just make sure that the computer is off when you are switching.
If you don't have an easy way to reset CMOS such as the jumper being directly under a video card, just make sure to make HT adjustments slowly. An unstable computer can at least post most of the time as long as its not an extremely unstable computer.
Remember the last thing, the only setting that can really damage components is the voltage. Be careful with this, and have fun experimenting with any other setting.
