I've been overclocking some 1600MHz ram on my xeon e3-1230 machine. I managed to get 2400MHz with 12-13-13-38 timings at 1.65v. Not exactly the best timings in the world, and definitely not as good as some of the kits with guaranteed XMP profiles. But I was still alright with it and heck, that was quite a big jump.
Couple weeks later I was thinking (in the shower) about how smoothly that overclock went and how I stopped at 2400MHz without trying for further. So I go back to overclocking this ram again, this time I did some stupid timings like 14-15-15-40 with 2600MHz at 1.7v. Boots perfect, passes a prime95 test with no hicups.
So realistically, is it worth it? To have the timings so high if the rest of the system can handle it? What are the downfalls? Latency?
Also, people often say that the 4th timing should be equal to the sum of the first second and third timing? Is that true? It appears that the fourth timing only goes to 40. Is this the same for all motherboards?
I'm also thinking of going further for the heck of curiosity.
