Sorry. Got carried away
All those terms relate to the timings (and what affects what). They are what you see when in the BIOS and in apps like CPU-Z
Also if it makes a difference it's 4x4gb sticks, 2 8gb packs I got in a sweet deal.
4 filled dimm slots of 4GB modules - Ocing the RAM is now harder due to more variables involved (voltage/individual module capabilities etc)
Doable - but realistically not worth it.
I hear that it provides no noticeable difference and is hardly worth the trouble, but then you get 1333mhz kits at 8-8-8-24 latencies that run better, am I to assume this extra 2gb/s or 1.5 second improvement is not really noticeable?
The way RAM is sold, depends on how 'well binned' it is.
For example, from a production run (yield) of X amount of modules, those modules that perform better than others from the same yield are 'matched' with similar performing modules and then sold as kits.
Since some RAM quality is better than others, they are then sold at varying performance/price points. The 'poorer binned' modules are usually the budget/high latency kits. ie 9-9-9-24 1333mhz
The slightly better ones are sold at the same speed, but with lower latencies because they handle it. Or, they keep the 9-9-9-24 timings but sell it as 1600mhz and so on and so forth.
To keep quotas for a range etc, some RAM that is
capable of high Mhz/low latency are sold as a slower kit to 'make up the numbers'. This is where luck of the draw comes into it. Those that can squeeze more mhz or tighter timings from cheaper/lower speed modules might actually have some of the modules that are better binned, yet 'sacrificed' to make up the numbers. Those that can't, have a module/s already at their limit.
It's a simplified explanation, but hopefully it gives you an idea why some can 'wring more out of' the same model you have.
(The binning process also applies to CPUs, GPU's etc. That's why some CPU's and GPU's will overclock really high with really low voltages, compared to others who have to max the volts just to hit the same clock speed. )

That pretty much sums it up. Particularly with 16GB.
If they have an X.M.P profile - set it and forget it. As tw33k mentioned, outside of benchmarks, the 'noticeable' performance difference is practically negligible.
(You've really got to start wringing the nuts off it to visibly
notice a difference)
