Looking for some Phenom II 955 OC settings

Hi All,

My head is spinning from all the overclocking guides/threads/tips/vids and i know there's lots of great tutorials out there, but I'm just wondering if any AMD 955/965 users can tell me what worked for them to get a stable 3.8-4.0 ghz overclock? looking for combination of all changes made to Multiplier, Voltage, FSB, NB, HT, memory timings/memory voltage etc. (by the way I'm still using DDR2 so i'd like to hear from any fellow ddr2 users on this subject as well)

I also have a question: As I mentioned above I'm using DDR2 800 PC2-6400 ram (2X2gb), CAS latency 5, timings 5-5-5-15. Being a n00b to overclocking will I have to change my ram settings/overclock it in order to run a stable 3.8 ghz cpu overclock, or can I leave that part alone? The RAM part of overclocking is confusing to me. my mobo manual says I can overclock ddr2 up to 1200, and several people on newegg said my RAM is overclockable to at least 1066.

This may also be a stupid question, so bear with me, but is overclocking ram how you get the latency/timings down too? I'm optimizing for FSX and I've heard that getting ddr2 timings down to 4-4-4 is best for the program.

Thanks!
