4-4-4 and 5-5-5

[fructinhit]

If I'm getting 2 gigs of memory (2x1gb) that is DDR2 800, would I see a large difference with a 4-4-4 timing from a 5-5-5, or is it not that big of an issue? I'm tempted to buy some g.skill memory with the 5-5-5 timings, but am wondering if I should definitely go for a 4-4-4 pair no matter what.

With Intel chips the differance is so small. For overclocking those G.Skill 6400 CL4 HZ's are awesome, and with those G.Skill's I've seen a 380MHz overclock on those 6400 HZ's. They only cost 124.99 at NewEgg.

How about 4-4-3-5 vs. 5-5-5-18 with same type of RAM? Would the 4-4-3-5 have any significant advantage?

There IS a difference - but you will probably not feel it.
But there IS, no doubt about it - especially the first number which is the CAS Latency is very important since it is the latency (measured in clock cycles) for all read/write access to memory banks which is done all the time.

The differance is WAY too small to notice in almost any program. In the real world where I live you can't notice a diff, it matters most with AMD proceesers. Your reading too much into it, go with real world differance's.

That's kind of what I said - that there is a difference however one is not likely to notice it.
