Memory Overclocking

[nel]

I happen to have a ddr2-533 and has a timing of 4-4-4-12 and I did overclocked it to ddr2-600 with the same timing.
Now, is it better if I change the timing to 5-5-5-15 and overclock to ddr2-667.
By the way, I have a Pentium 4 3.20 800fsb 65nm w/h
overclocked to 3.60 900fsb

I personally would stay at ddr2-600 and keep the tighter timings than loosen the timings for 67mhz more mem fsb which I don't think is noticeable anyway.
