I know this guide has been here a while but this was the first time I actually read it all the way through. It was a very good guide. I would be too lazy to do anything like that. I just have a few suggestions though.
The HT frequency is how the cpu communicates with the chipset. The multiplier times your fsb should be 800mhz-1100mhz. So like if your fsb was at 300 you would want your HT multiplier set at 3(3x300=900).
Also if you dont want to run at a divider you can just loosen the timings on your memory. Mainly your CAS, TRAS, Trcd, and Trp numbers. Usually you willnt want to lower them any more then 3-4-4-8. Then if your memory isnt stable after that you can always increase your memory's voltage. If you dont understand that then run a divider.
