actually, after reading that article, it seems quite outdated. I bet the same principles apply though, especially the fact that the difference between the two tradeoffs are most likely within a few percentage points.
I think it depends on what CPU you have. The AMD Phenom II's loved higher frequency with NB overclock. There was drastic improvements with this in benches, although I'm not sure how much that translates to real world performance. I was seeing results of nearly 20% better in things like MAXXMEM vs CL8 1600.
Not sure how Intel fares with frequency vs. timings, but I suspect frequency would pull ahead also, although CL11 is a bit high for only 1866. I think i'd just stick to CL9 1600 if on Intel.
If you want to know which is best for you, try running both settings on MAXXMEM and compare the results.
